# Client crashes, freezes and failed tool execution (`rel.client_failures`)

Feedback Bench, coding agents, built 2026-10-01, window 2026-08-31 to 2026-09-27. Web page: https://feedbackbench.com/#/criterion/rel.client_failures

Area: [Reliability and speed](https://feedbackbench.com/criteria/reliability.md)

**Definition.** The local app, CLI or extension crashes, freezes, leaks memory or uses too much CPU, or fails to execute the model's tool calls and shell commands.

**Boundary.** Not this: see [Outages, server errors and capacity or rate errors](https://feedbackbench.com/criteria/rel.service_errors.md) for backend outages and server errors. Not this: see [Updates break working setups](https://feedbackbench.com/criteria/rel.update_breakage.md) when a specific update caused it.

## The brief

Written by Claude Opus 5.5 from 101 labelled posts and the numbers on this page. Interpretation, not measurement: every quote is verbatim and links to its post.

**Lean terminal clients hold up; heavy desktop apps freeze, bloat and stall.**

TL;DR:

- Codex and Antigravity draw the most crash, freeze and lag complaints, both worse than peers.
- Zed, Pi and Claude Code stand out for light footprints and fewer client failures.
- Recurring pain: hung UIs, runaway RAM, failed tool calls, sessions that silently stop.

In plain terms: Expect the app itself to be the weak link. Users kill frozen processes, restart to clear zombie agents, and watch RAM climb. Many retreat to the CLI, which posts describe as lighter and steadier.

### How it breaks

- **Desktop apps freeze and lock up** ([Client crashes, freezes and failed tool execution](https://feedbackbench.com/criteria/rel.client_failures.md)). The most common failure is a GUI that stops responding mid-task, forcing users to kill the process or close the terminal.
  Posts describe loading spinners that never clear, input that stops registering while the cursor still blinks, and UIs lagging several words behind typing. Devin CLI users report freezes on long file writes that only a fresh process fixes. A Claude Code user says the desktop app lags the whole machine and the CLI is better. Freezing mid-task is one of the most-requested fixes, led by Codex and Cursor users.
  Evidence:
  - Complaint, Claude Code, @ClaudeDevs, 2026-09-25: “@claudedevs still lags and freezes my machine. cli is better” [source](https://twitter.com/44595437/status/2103303119799210260)
  - Complaint, Devin, r/windsurf, 2026-09-03: “when writing longer files, such as markdown plans or html for documentation, devin cli has been constantly freezing up on me. i tried hitting ctrl+c, ctrl+z, ctrl+l, ctrl+shift+l, and nothing happens. the cursor in the chat is still blinking, and i can still scroll, but typing does nothing, refreshing, stopping -- nothing seems to work besides closing the terminal and starting a new process. by the way, i am in windows 11/windows terminal/wsl2/debian trixie/devin 3000.5.20 (2d902011). is anyone else having this problem? some of my teammates are occasionally having this problem, but not nearly as much as i am.” [source](https://www.reddit.com/r/windsurf/comments/1w6eoh8/devin_cli_freezes_but_continues_in_background/)
  - Complaint, Devin, @cognition, 2026-09-12: “i really like what @cognition is building with @devindesktop, but the client experience is really having some state, process management, and ux issues: -sessions disappearing and losing history (!!!) -the ui locking up to 3 *word* input lag -silent devin -p failures (1/3)” [source](https://twitter.com/928932212/status/2098854625323463157)
  - Complaint, OpenAI Codex, r/codex, 2026-09-27: “windows desktop app. unfortunately as a windows user i feel we are often neglected. super buggy - and it's been since the latest release that the bug is high impact (stuck at loading spinner unless we kill codex.exe). even then, codex works but not chatgpt. sometimes i use codex cli (with wsl) for windows, but i mostly use the desktop app. i hope they pay attention to users that are on other os other than macos.” [source](https://www.reddit.com/r/codex/comments/1wra4ev/codex_on_windows_do_you_work_with_wsl_agent/pcc70fw/)

- **Memory and CPU run away** ([Client crashes, freezes and failed tool execution](https://feedbackbench.com/criteria/rel.client_failures.md)). Clients leak memory as sessions grow and leave helper processes alive, turning a coding agent into the heaviest thing on the machine.
  A Cursor user finds stopped sub-agents relaunching on every start and holding gigabytes of RAM. A Devin Ask user watches the tab climb past 8 GB around fifty prompts and suggests virtualizing chat history. Zed users report idle CPU above VS Code. Leaked-process cleanup and RAM reduction both appear on the request list across many vendors.
  Evidence:
  - Complaint, Cursor, @cursor_ai, 2026-09-16: “@cursor_ai having an issue with zombie sub-agents restarting every time i launch cursor. currently eating ~5gb of ram running 11 sub-agents i stopped yesterday. any fix?” [source](https://twitter.com/1481656122645696518/status/2100354201171698135)
  - Complaint, Devin, r/CognitionLabs, 2026-09-15: “i’ve been running into a pretty rough performance issue with devin ask on longer conversations. i’m on windows 10 using operagx, with an older phenom ii x6 1100t be and 12 gb of ddr3 ram, so my machine is definitely not new, but the devin tab starts using 8 gb+ of ram once the conversation gets to around 50 prompts, and input lag becomes noticeable. the ram usage keeps climbing as the context grows. it feels like the chat canvas may be keeping too much of the conversation rendered in the dom at once. a quality-of-life improvement that would help a lot would be virtualizing the chat history, keeping only the most recent messages visible/rendered, maybe around 20 prompt/response pairs, and loading older content back only when scrolling up. other ai chat uis seem to handle long threads this way, and it would make devin ask much more usable on lower-end or older machines.” [source](https://www.reddit.com/r/CognitionLabs/comments/1wgoq0x/perf_issue/)
  - Complaint, Devin, @cognition, 2026-09-23: “i love devin but wtf is this memory consumption? @cognition @dabit3 <strict_link>” [source](https://twitter.com/1333116608609398785/status/2102571264183242968)
  - Complaint, Zed, r/ZedEditor, 2026-09-23: “same issue on sequoia. high cpu usage without any extensions or lsp. cpu usage consistently remains more than vscode with occasional spikes.” [source](https://www.reddit.com/r/ZedEditor/comments/1sbyj79/zed_high_memory_and_cpu_usage_on_mac/pbi6zvh/)

- **Tool calls fail to execute** ([Client crashes, freezes and failed tool execution](https://feedbackbench.com/criteria/rel.client_failures.md)). The model asks for an action and the harness cannot run it, burning credits or retries for nothing.
  Warp users say tool-call failures consume credits and deliver nothing. Antigravity users count retries before a command executes correctly. Copilot users say the harness repeatedly fails read and write operations, and that hung tools waiting on input need manual rules to avoid. Pi users report the stock edit and read tools failing schema validation, with one user building a fix after mining months of edit failures.
  Evidence:
  - Complaint, Warp, @warpdotdev, 2026-09-02: “@warpdotdev when can you guys fix the tool calling failure issues? it burn my credit but deliver nothing.” [source](https://twitter.com/268717001/status/2095001516151132453)
  - Complaint, Google Antigravity, r/google_antigravity, 2026-09-07: “it's meh compared to fable / astra but definitely a massive leg up compared to 3.5 and 3.1 of its own family. i'm comparing "tool usage" how many times does it need to retry to get a command correctly executed” [source](https://www.reddit.com/r/google_antigravity/comments/1w9vwgv/tbh_flash_38_is_really_good_when_it_comes_in/p8e9t6y/)
  - Complaint, GitHub Copilot, r/GithubCopilot, 2026-09-27: “why would you wanna use copilot harness? it keeps making mistakes, ignore instructions and repeatedly fails read/write ops. another person in this sub posted benchmarks that put it lower than other harnesses like pi/ds/codex” [source](https://www.reddit.com/r/GithubCopilot/comments/1wr5io2/best_cheaper_alternative/pca0pix/)
  - Complaint, Pi, r/PiCodingAgent, 2026-09-13: “not hashline edit (imho doesn't work well), but i've had this problem with pi's edit tool for a long time, basically mined every single type of edit failure from 6+ months of usage and then found which ones can be fixed programmatically, the rest i enhanced with better errors the agent can act on. shameless self plug <strict_link>” [source](https://www.reddit.com/r/PiCodingAgent/comments/1wfavpg/which_hash_line_extension_solves_constant_the_old/p9lynql/)

- **Sessions silently stop mid-run** ([Client crashes, freezes and failed tool execution](https://feedbackbench.com/criteria/rel.client_failures.md)). Long runs halt without a clear error, and the only recovery is nudging the agent or starting a new session.
  Cline users report sessions dying around the half-hour to hour mark on every model, sometimes recoverable by switching models. OpenCode users describe the agent waiting forever after running a command until they type something. Conductor and Cursor users see agents that just stop responding or drop queued messages. Unattended work is where this hurts most, and users say it blocks automated workflows.
  Evidence:
  - Complaint, Cline, @cline, 2026-09-26: “@cline this happens a lot for no reason. sometimes changing the model works and able to continue, other times just have to create a new session entirely. usually, happens at 37m or 1hr mark. happens on all (free and paid) models. <strict_link>” [source](https://twitter.com/220288969/status/2103715062653636714)
  - Complaint, OpenCode, r/opencode, 2026-09-08: “when i run some sessions, opencode sometimes just pauses, until i type something it it, and it acts like nothing happened. it's like it's waiting for a response or something and never gets it and just waits forever. it especially happens when it runs a command it sends. sometimes it seems to compact immediately after i wake it up. so maybe that has something to do with it? anyone else having this issue? i'm using llama.cpp, qwen 3.8 27b, 128k context. latest opencode. thanks in advance!” [source](https://www.reddit.com/r/opencode/comments/1wa9yj0/opencode_pausing/)
  - Complaint, Conductor, @conductor_build, 2026-09-21: “@charlieholtz i have no idea whether its an issue with @cursor_ai or @conductor_build but cursor agents sometimes they just stop responding in conductor cloud. it has happened to me thrice in the past 3 days. please figure it out and fix it? i am happy to provide any details for you to debug if needed.” [source](https://twitter.com/1900337293564817408/status/2101825344626208846)
  - Complaint, Cursor, @cursor_ai, 2026-09-22: “@cursor_ai message queueing is broken for about a week now, even after the latest update. the message is posted to the timeline after the agents turn has finished, but then just stops.” [source](https://twitter.com/9172042/status/2102328449134116906)

- **The CLI outlasts the app** ([Client crashes, freezes and failed tool execution](https://feedbackbench.com/criteria/rel.client_failures.md)). Across vendors, users praise the terminal client and blame the desktop app, using the CLI as their stability fallback.
  A Factory user calls the CLI amazing and the app buggy. Codex users say the CLI uses less CPU and memory and lets them run multiple instances freely. An OpenCode user on Linux avoids GUI harnesses entirely for resource reasons. The pattern is consistent enough that it reads as a product signal: the desktop wrappers are where client failures concentrate.
  Evidence:
  - Complaint, Factory, @droid, 2026-09-21: “@ain3sh @benvargas @droid hey a fellow droid user here, the cli is amazing, the app not so much, there were some bugs here and there. only thing with the cli is the rendering can be improved, it's a bit janky on missions, maybe you guys can move to a different framework from ink?” [source](https://twitter.com/1333161864/status/2101883259831632365)
  - Praise, OpenAI Codex, X search: OpenAI Codex, Codex CLI, Codex app, 2026-09-20: “the codex cli actually consumes less cpu and memory than pi, which is somewhat surprising. <strict_link>” [source](https://twitter.com/1732683816685514752/status/2101508430326591969)
  - Praise, OpenAI Codex, X search: OpenAI Codex, Codex CLI, Codex app, 2026-09-07: “personally, i think the opposite... i'm overwhelmingly a cli person. i tried using the desktop for the sol and hackathon topics & implementation, but in the end, i open the terminal for commands and file operations, which crowds the screen. if i use codex cli in the terminal, i can use multiple instances and arrange them freely, and it consumes less memory. also, working with wsl on windows is cumbersome... (the image is gnome) i haven't encountered any benefits other than the cuteness of pets...” [source](https://twitter.com/1743042073962672129/status/2096954964002377745)
  - Praise, OpenCode, r/opencode, 2026-09-20: “maybe , i dont have a mac machine , i have linux and windows , there is no problem in linux using opencode ans other harness on cli or tui and i will not reccomend (spelling mistake) because they f*cking consumes the system resources so heavily , i will prefer the cli or tui still you can install the tui of opencode in windows refer this doc : <strict_link>” [source](https://www.reddit.com/r/opencode/comments/1wlkq6c/windows_app_has_no_plan_mode/pazicsc/)

### Who stands out

- **OpenAI Codex (weaker)**. Codex dominates the complaint volume here, with the desktop app crashing, hanging on launch and lagging while the CLI earns quiet praise.
  Windows users report the app stuck at a loading spinner until they kill the process, and say non-macOS users feel neglected. Others see random crash-and-restart loops and broken projects across machines. Codex users file most requests for fixing laggy UI, 17 of 24. A Cursor user praises Cursor for not hogging the computer like Codex. On the other side, CLI users describe smooth, low-memory runs.
  Evidence:
  - Complaint, OpenAI Codex, X search: OpenAI Codex, Codex CLI, Codex app, 2026-09-23: “codex keeps randomly crashing and restarting on its own, hope they fix this soon @openai #codex <strict_link>” [source](https://twitter.com/1247015624/status/2102672150406525224)
  - Complaint, OpenAI Codex, r/codex, 2026-09-27: “windows desktop app. unfortunately as a windows user i feel we are often neglected. super buggy - and it's been since the latest release that the bug is high impact (stuck at loading spinner unless we kill codex.exe). even then, codex works but not chatgpt. sometimes i use codex cli (with wsl) for windows, but i mostly use the desktop app. i hope they pay attention to users that are on other os other than macos.” [source](https://www.reddit.com/r/codex/comments/1wra4ev/codex_on_windows_do_you_work_with_wsl_agent/pcc70fw/)
  - Complaint, OpenAI Codex, r/codex, 2026-09-25: “i have exactly the same issue on 2 computers now. i got codex to write a work around, but it means i am unable to use projects. if anyone has this issue and knows a proper fix i am desperate.” [source](https://www.reddit.com/r/codex/comments/1wlkggh/codex_stops_working_after_the_first_message_in/pbyknow/)
  - Praise, Cursor, @cursor_ai, 2026-09-06: “been heavily using @cursor_ai desktop app last few days just to try it. gotta say i really like it. the simplicity of it is great, it doesnt have the issues of hogging computer like codex. obviously codex is my fav still cause of the computer use ability. but cursor is def second and if it had equal computer use id prolly use it more” [source](https://twitter.com/539363367/status/2096624059479994547)

- **Google Antigravity (weaker)**. Antigravity users report a harness that breaks at the plumbing level, from missing tool registrations to git index corruption.
  Subagents fail to start because a tool is not found in the registry. Users share aliases to repair corrupted git indexes and question whether the remote feature wears out their SSD. One user left the IDE for Zed after slowness and crashes. Praise exists, with some calling the harness stable and smooth, but complaints vastly outnumber it.
  Evidence:
  - Complaint, Google Antigravity, r/google_antigravity, 2026-09-01: “same, seems like it's just plain broken. >the subagent code review investigator (deepinvestigator) with id \[omitted\] encountered an error and has either stopped or failed to start execution: failed to construct executor: failed to resolve components: unknown component: tool "skill\_search" not found in registry” [source](https://www.reddit.com/r/google_antigravity/comments/1w4d47l/boost_mode_usage/p77zjpm/)
  - Complaint, Google Antigravity, r/google_antigravity, 2026-09-08: “the index corruption is real. `git config --global alias.fix-index '!rm -f .git/index && git reset'` then you can say `git fix-index` at least.” [source](https://www.reddit.com/r/google_antigravity/comments/1wau0ea/how_to_make_file_changes_auto_accept_all/p8l0cos/)
  - Complaint, Google Antigravity, @antigravity, 2026-09-24: “huh, @antigravity 's remote is silently destroying your ssd? <strict_link>” [source](https://twitter.com/1443206574835699715/status/2103251993494179853)
  - Praise, Zed, r/google_antigravity, 2026-09-09: “the ide is slow and crashes. i switched to zed so i can use the models is a stable and snappy ide.” [source](https://www.reddit.com/r/google_antigravity/comments/1waolu4/why_does_antigravity_have_so_few_users/p8r9iig/)

- **Zed (stronger)**. Zed draws users specifically because it stays light and fast, though some report CPU spikes and frozen git panels.
  Posts praise a small memory footprint, GPU rendering and relief for modest laptops, and some arrive fleeing crashier IDEs. The complaints are real but narrower: high idle CPU on macOS, a git panel stuck pushing until restart, and machine-specific freezes on one Linux laptop that the same user's desktop does not show.
  Evidence:
  - Praise, Zed, @zeddotdev, 2026-09-13: “@arpit_bhayani i moved to @zeddotdev from vscode it's really great and runs under 200 mb.” [source](https://twitter.com/1302187537629413376/status/2099140245241594089)
  - Praise, Zed, @zeddotdev, 2026-09-27: “@0xprajwal_ i use @zeddotdev, btw. it’s fast, lightweight, consumes less memory, and uses the gpu for rendering.” [source](https://twitter.com/1542127649463898113/status/2104217257153110457)
  - Praise, Zed, @zeddotdev, 2026-09-25: “@zeddotdev my 16 gb ram development laptop is saved because of you!” [source](https://twitter.com/1115272367154950151/status/2103318390798774306)
  - Complaint, Zed, r/ZedEditor, 2026-09-12: “i have a cachyos laptop, which regularly has a frozen lap or git, or sometimes i just can't open files anymore. however on my cachyos desktop it works fine.” [source](https://www.reddit.com/r/ZedEditor/comments/1we3tul/instability_and_ui_lag/p9bepmk/)

- **Pi (stronger)**. Pi users praise its speed and low memory, and treat breakage as something the agent can fix itself.
  A user who swapped OpenCode for Pi reports it runs much faster and lighter. Another says six months without flicker problems, blaming one extension when it happened. Weak spots are tool-level: subagents failing on macOS while working on Linux, and edit-tool failures users have had to patch themselves.
  Evidence:
  - Praise, Pi, @pidotdev, 2026-09-04: “replaced opencode harness in 20x with @pidotdev and omg it's so much faster and consumes less memory.” [source](https://twitter.com/994170492901773312/status/2095929704993931715)
  - Praise, Pi, r/PiCodingAgent, 2026-09-14: “in six months i've never had this with pi. the only time i had flicker problems it was an extension i was running.” [source](https://www.reddit.com/r/PiCodingAgent/comments/1wfvx2f/any_idea_how_to_resolve_for_this/p9q22uh/)
  - Complaint, Pi, r/PiCodingAgent, 2026-09-24: “just found an issue. everything was great on my linux desktop, but when i moved to my mac (darwin) it just doesn't work at all. a new pane opens, containing just this: echo __pi_herdsman_ready_5b4c042a-589a-48dd-a0c3-1b1e92f215e9__  echo __pi_herdsman_ready_5b4c042a-589a-48dd-a0c3-1b1e92f215e9__ __pi_herdsman_ready_5b4c042a-589a-48dd-a0c3-1b1e92f215e9__ and the subagent simply fails immediately. that pane also stays open. sorry for bad formatting, i'm on phone, not home. i have no idea why this is happening, but maybe it helps you herdr v0.9.1, pi 0.87.1, ghostty” [source](https://www.reddit.com/r/PiCodingAgent/comments/1woif1b/i_built_pi_herdsman_for_async_subagents_with/pbsl1ks/)
  - Complaint, Pi, r/PiCodingAgent, 2026-09-13: “not hashline edit (imho doesn't work well), but i've had this problem with pi's edit tool for a long time, basically mined every single type of edit failure from 6+ months of usage and then found which ones can be fixed programmatically, the rest i enhanced with better errors the agent can act on. shameless self plug <strict_link>” [source](https://www.reddit.com/r/PiCodingAgent/comments/1wfavpg/which_hash_line_extension_solves_constant_the_old/p9lynql/)

- **Claude Code (stronger)**. Claude Code rates better than peers, with users citing modest resource use, though the desktop app still lags and stuck daemons need manual kills.
  Users report zero issues across Linux, macOS and Windows and expect quiet fans because the client stays light. Complaints center on the desktop app: slow side chats, machine-wide lag, and a stuck state one user escaped only by killing a supervisor process from a lock file.
  Evidence:
  - Praise, Claude Code, r/ClaudeCode, 2026-09-04: “yeah bro you have got something else going on the app works great for me zero issues” [source](https://www.reddit.com/r/ClaudeCode/comments/1w76z28/why_cant_anthropic_have_claude_make_their_desktop/p7usuhp/)
  - Praise, Claude Code, r/ClaudeCode, 2026-09-26: “i haven’t had any issues with it at all. i also keep pwsh on linux and maxos and it works on all three major platforms as a result 🤷♂️” [source](https://www.reddit.com/r/ClaudeCode/comments/1wqwi4h/why_claude_code_uses_python_for_everything_and/pc9n3w8/)
  - Complaint, Claude Code, r/ClaudeCode, 2026-09-05: “this is such a bullshit feature, its a bug, if im right, ctrl-x will delete it, the only one way to get unstuck out of it is by find and kill supervisor pid is in \~/.claude/daemon.lock, it quite complicated so ask your ai to do it for you, worked for me” [source](https://www.reddit.com/r/ClaudeCode/comments/1vwtzpf/how_to_completely_exit_a_background_agent/p7vygdv/)
  - Complaint, Claude Code, @ClaudeDevs, 2026-09-23: “@claudedevs @_catwu desktop app /btw (side chat) conversation is still slow, sometimes it shows error. side chats are very important, it helps keeping conversations unpolluted. please make it 3x faster. 🥲” [source](https://twitter.com/490212419/status/2102899328000172040)

### Fine print

- Posts here skew heavily toward complaints for every agent, since users rarely post when a client simply works.
- Some failures involve local model servers or user hardware, which posts cannot always separate from the client itself.
- Several posts tie problems to recent releases; those overlap with update breakage and may be counted there too.

## Top requests

What users ask to add or change, most asked first. 458 author-weeks ask for something. Requests do not change the Feedback Score. Rule: A separate pass by Claude Sonnet 5 reads every counted post and extracts what the author asks the agent or its vendor to add or change, with the criteria it maps to and a short normalised wording; it does not touch the labels or the Feedback Score. Claude Opus 5.5 groups the wordings within each criterion (the first criterion the request maps to) into themes; code counts them. A theme counts distinct author-weeks that ask for it, per agent; across agents, one author-week per agent. Themes asked in fewer than 2 author-weeks, and requests that share no theme, are not shown. Examples: up to 3 posts per theme from different authors, without slurs, preferring posts of 60 to 450 characters, most recent first.
