Claude Code and Codex limit tools compared
Independent project. Not affiliated with Anthropic or OpenAI.
Usage limits are now part of daily life with coding agents, and a small crop of tools has appeared to deal with them. Some warn you before you run out. Some wait for the reset and carry on. Some hand your work to a different agent. This page compares them as fairly as we can.
We make one of these tools, so read this with that in mind. To keep it honest, every competitor row below only states what that tool's own page says, with a link, and we list where Limit Rescue falls short.
The short answer
If you use Claude Code and Codex and want a heads-up before the limit plus a handoff note and a one-command switch to the other agent, that is what Limit Rescue is for. It warns at 80% and 95% of your usage limit, writes a "Where I left off" note, and limitrescue resume codex or limitrescue resume claude continues the work in the other agent. It runs locally and makes no network calls.
But it is v0.1.0 in early access, not public yet, and several of the tools below are further along. Jump to where Limit Rescue falls short and how to choose.
What we compared
"Checked 2 November 2026" means we read the linked page that day. Features are as described on that page. We did not install or test the competing tools, so we cannot vouch for how well they work. If a page changes, the page wins.
Tools that warn, resume, or hand off
| Tool | What its page says it does | Agents named | Platforms named | Network note from its page | Source |
|---|---|---|---|---|---|
| Limit Rescue (v0.1.0, early access) | Warns at 80% and 95% of your usage limit, writes a "Where I left off" note, and limitrescue resume codex / limitrescue resume claude continues the work in the other agent |
Claude Code, Codex | Tested on macOS so far | Makes no network calls | limitrescue.com |
| noctis | A Claude Code plugin that saves a checkpoint and pauses before the 5-hour or weekly limit (defaults 92% and 95%), then resumes the same session after the reset. Can also run a job queue from a file | Claude Code; also runs in Codex CLI, Antigravity CLI, Factory Droid and Copilot CLI with fewer features | Windows, macOS, Linux | Reads usage from the status line first, and may ask the usage endpoint the Claude app uses, with your stored login token. A once-a-day update check goes to GitHub. No telemetry | claude-mods.com/noctis |
| spare10 | A plugin that holds work at the last 10% of the 5-hour or weekly quota (reserve defaults to 10%) and asks whether to stop or resume. At 100% it holds until the reset | Claude Code; the same plugin also runs in the Codex CLI | Not stated on the page we read | No network calls and no processes run | claude-mods.com/spare10 |
| cas | Wraps claude or codex. It detects the limit, waits for the reset, then types continue or relaunches with claude --continue (codex resume --last for Codex). Resumes the same agent, it does not hand off to another one |
Claude Code, Codex | macOS, Linux | Not stated in the README | github.com/cloud-007/agent-auto-start |
| ccam | Manages several Claude Code accounts, each in its own config directory. ccam usage shows 5-hour and weekly usage per account, and ccam next --auto --continue continues the same conversation on the account with the most headroom |
Claude Code only | Linux, macOS, Windows | Not stated on the page we read | ccam.dev |
| agent-baton | Monitors usage for Claude Code and Codex, warns before a threshold (the README's default hard threshold is 95%, with a warning band 5 points below) and writes a Markdown handoff with git evidence. baton pickup --to codex or --to claude starts the other agent |
Claude Code, Codex. Cursor and Gemini CLI get a transcript fallback only | macOS, Linux, WSL (README badges) | The README says Claude usage is detected via an OAuth token and the Claude usage API. Codex usage is read from local session files | github.com/codeprakhar25/agent-baton |
| keepitmovin | Runs your AI coding tools in one terminal in a fallback order you choose (movin). When a tool hits its limit it hands the next tool a handoff file. Says it cannot copy a tool's private chat state |
13 tools listed, including Claude Code, Codex and Grok Build | Not stated in what we read. Needs Node 22.12 or newer and uses node-pty | Says handoff prompts are generated locally with no extra network calls | github.com/garrettsiegel/keepitmovin |
| PonyMux | A terminal app that organizes Claude Code, Codex and Grok sessions. Its Handoff action reads a session transcript, writes a Markdown file (title, summary if any, last five exchanges, transcript path) and starts the other agent with it. Its home page also shows usage windows per agent | Claude Code, Codex, Grok | macOS and Windows | Not stated on the pages we read | ponymux.com and its handoff guide |
| Lifeline (v0.2.1 public beta) | Run lifeline claude, lifeline codex or lifeline gemini. When it sees a usage-limit message it captures that session and opens another AI with the context loaded. Can also switch before the limit from a second terminal. Redacts secrets from the handoff |
Claude Code, Codex, Gemini | macOS primary; Windows, Linux and WSL in beta | Its page says session content goes to the other AI provider, so it redacts secrets locally first. Only works for sessions started through Lifeline | pypi.org/project/lifeline |
| PlanLimits CLI (v0.2.2) | A Node tool that reads your local Claude Code and Codex logs. planlimits watch alerts at 80% (configurable) and 100% of a 5-hour or weekly window. A Claude Code hook can save a handoff file, and planlimits handoff codex starts Codex with it. The page notes Claude percentages are estimates and that it cannot move or pause a running session |
Claude Code, Codex (other tools set manually) | Not stated on the page we read | watch sends nothing. The route command can send plan ids, states and task type unless you use --offline. Not on npm; it runs from the site |
planlimits.app/cli |
| Ceiling Guard | Shows how much of your Claude Code, Codex or Grok subscription window is left, warns your agent before it runs out (default 95% of the binding window) and writes a handoff for the next run. The handoff is a record of what it observed, not a summary the agent wrote | Claude Code, Codex, Grok | Linux, macOS, Windows, or a container | Reads usage files the CLIs already write; says no provider credentials and no proxy. For Claude it needs one wrapped claude -p run to read the percentage |
pypi.org/project/ceiling-guard. PyPI showed every listed release as yanked ("no reason given") when we looked, so check its status before relying on it |
Notes on a few rows
- noctis and spare10 are the closest fit if you only use Claude Code and want it to pause and resume on its own. Neither is described as handing off to a different agent.
- cas and ccam keep you on the same agent (or the same agent on a different account) rather than switching tools.
- agent-baton, keepitmovin, Lifeline, PlanLimits and PonyMux are the closest in spirit to Limit Rescue because they include a handoff to another agent. They differ in when they act: before the limit (agent-baton, PlanLimits, Ceiling Guard), when the limit message appears (Lifeline, keepitmovin), or when you click (PonyMux).
- Limit Rescue aims at the same moment, with a deliberately small scope: two agents, a warning at two points, one note, one resume command.
- Details such as thresholds are copied from each page and can change. Please read the source before you rely on a number.
Adjacent tools (a different kind of thing)
These come up in the same searches. They help you keep context across agents, but their pages do not describe usage-limit warnings.
| Tool | What its page says it does | Source |
|---|---|---|
| Taskhold | A hosted task list shared by you and your AI agents over MCP (Claude Code, Cursor, Codex, Windsurf, VS Code Copilot, Gemini CLI and others), so another agent can pick up the open step. It is a subscription product per its page. Its own guide says it does not watch your usage or restart a session | taskhold.com and its limit guide |
| Sharkly | A team workspace and project management tool where AI agents (Claude Code, Codex, Cursor and others) work as teammates with tasks, sprints and worktrees. We did not see usage-limit warnings described on its home page | sharkly.ai |
| Agent.Space | A shared workspace where you can switch between Codex and Claude Code on the same files. Its use-case page lists hitting a usage limit as a reason to switch. It says files, diffs and test results carry over, a person writes a short handoff, and the sessions stay separate | dev.agent.space use case |
| Qarinah | Local project memory and cited context packs shared across coding agents, with hooks for Claude Code and Cursor integrations. Metadata-only by default and no account needed. We did not see usage-limit warnings described | qarinah.io |
A note on Grok Build
PonyMux's guide says Grok Build can pick up a Claude Code or Codex session directly with /resume-claude and /resume-codex. We checked that against Grok Build's own source repository rather than taking PonyMux's word for it.
- Grok Build's repository describes it as a terminal-based AI coding agent, and its tutorial for people coming from another tool says: "The /resume-claude, /resume-codex, and /resume-cursor skills continue a recent session from those tools right here." (source in the Grok Build repo)
- Its configuration guide says each tool needs both its sessions compatibility setting and the matching skill ("Harness compatibility" in
docs/user-guide/05-configuration.md). - Two caveats: they are skills, not core built-in commands, and they only work in one direction, into Grok Build. We also did not find them on the docs.x.ai CLI reference page we read, so check which version you have.
So it is confirmed by Grok Build's own repository, with those caveats. We have not tried it.
Where Limit Rescue falls short
Plainly:
- Not public yet. v0.1.0 is in early access and is not on npm. Today the only way in is the early-access list on limitrescue.com. Several tools above you can inspect and install right now.
- Tested on macOS only so far. Several tools above name Windows and Linux support.
- Only Claude Code and Codex. keepitmovin lists 13 tools. Lifeline, PonyMux and Ceiling Guard include Grok or Gemini.
- It does not wait out the reset and continue the same session for you. If you just want Claude Code to wait and continue after the reset, noctis, cas or Claude Code's own wait feature are closer to that.
- It is new. Fewer people have used it, and the others have more history.
How to choose
- Only Claude Code, want it to wait and carry on: look at noctis, spare10, cas, or the wait feature built into Claude Code. See what to do when Claude Code hits its limit.
- Several Claude accounts: ccam.
- Want a terminal that manages many agent sessions, with a handoff button: PonyMux.
- Want automatic fallback across many agents, today: keepitmovin or Lifeline.
- Want a heads-up before the limit and a handoff note, for Claude Code and Codex, and are happy to wait for a small, local tool: Limit Rescue.
- Want shared context or tasks across agents rather than limit handling: Taskhold, Agent.Space or Qarinah.
- Want to do it by hand: switch from Claude Code to Codex with a handoff note. It works with no tools at all.
