This conversation is saved. Continue after the provider resets, or start with another available account or provider.

The Default account just hit its session limit. Press Continue on Work to carry the task to your other account with a short briefing. Every reply here is prepared, and nothing you type is sent or saved.

Multiple accounts

Hit a limit on one account. Keep going on another.

When a session runs out of provider quota, Crowsnest offers to continue on a second subscription account you are already signed into. It quotes a compact briefing into a fresh session under that account and keeps the lineage back to the original — an attributed fork, never a disguised native resume.

  • Claude Code and Codex alike; each account keeps its own config directory.
  • Fresh installs ask first; optional automatic continuation acts only with one unambiguous destination.
  • Opt-in routing uses readable allowance evidence; a missing reading never masquerades as zero.

UI Studio

Point at the interface. Hand the change to an agent.

Open a live preview of an enabled project, select an element, and make reversible visual drafts — text, spacing, radius, size. Crowsnest turns the selection and your draft into a provider-neutral component brief and sends it to Claude Code or Codex.

  • An accessible selection breadcrumb with bounded DOM and style context.
  • Drafts are reversible — nothing is written until an agent writes it.
  • Send the batch to a new Claude Code or Codex chat, or attach it to the conversation you are in.

Insights

Local usage summaries keep limits, activity, and cost evidence clear.

Explore usage across 7, 30, 90 or 365 days, or all recorded history, broken down by supported dimensions such as day, model, project, hour, cache behaviour, and conversation. It is built from the transcripts already on disk — producing it uploads nothing.

  • Claude values are local estimates; Codex cost is API-equivalent only when enough counters exist.
  • Unsupported dimensions are omitted rather than filled with invented zeroes.
  • An estimate or provider evidence as labeled — never a billing ledger.

The workspace runs on your machine.

Byte-preserving repair

Rewrite one Claude turn in place; safe resume with original context.

Native continuation

Continue Claude Code and Codex in their own runtimes, in the browser; how Codex resume works.

Cross-provider handoff

Move work between agents as an explicit fork with visible lineage.

Local Insights

Usage summaries, cost, and cache behavior over time, with labeled provenance.

Loopback-only

No conversation upload or telemetry. Outbound calls are account sign-in, an update check you allow, and connections you start. What “local” means.

Try it for seven days. Then choose your workspace.

Your first sign-in starts one fixed seven-day Standard trial. Then choose Standard for the one-agent workspace, Pro for handoff, UI Studio, and several accounts, or Premium for everything in Pro with lifetime updates.

Where the boundary sits

  • The trial does not reset. It starts on the account's first sign-in and ends seven days later, even after another sign-in, refresh, or reinstall.
  • No model usage is included. Crowsnest coordinates the Claude Code and Codex runtimes already installed on your machine. You keep paying Anthropic and OpenAI directly under your own plans, and you need at least one of them for Crowsnest to be useful at all.
  • Payment follows your account. Use the same email at Polar checkout and Crowsnest sign-in. Refresh after payment obtains the signed Standard, Pro, or Premium plan; the client cannot edit it.
  • The available plans are one-time purchases. Standard is $19.99 and Pro is $69.99 in USD. Premium has a $99 launch price, 50% off $198. Polar displays the final amount at checkout.
  • No local data is removed when the trial ends. The workspace locks until Standard, Pro, or Premium is active, then opens the same files again.

A current signed access document works offline, with no background payment polling.

The questions a developer asks first.

Where does my data go?

Conversations stay on the machine that owns them. The local interface binds to 127.0.0.1, and transcripts, prompts, answers, project paths, and provider-native history are never uploaded to Crowsnest. The official app sends account credentials only for sign-in and session refresh, and, if you allow it, checks one signed update feed with no workspace or account data. Optional connections you set up send only the content of an action you start to the destination you chose.

Does editing a past turn break claude --resume?

No. Editing rewrites one line in place while preserving its UUID and tool pairings and keeping every other JSONL line byte-for-byte identical, so resume retains the original surrounding context. Edits keep recoverable backups. For the native continuation paths, see how to resume or restore a Claude Code session.

Which agents does it work with?

Claude Code, Codex, and GitHub Copilot. Claude history is the deeply editable format; completed Codex history stays immutable and is changed through its native fork/retry operations instead. Copilot chats run through GitHub’s standalone copilot CLI and your existing Copilot subscription, so their prompts go to GitHub under GitHub’s usage policy. Multiple accounts and handoff cover Claude Code and Codex.

Can I use Claude Code and Codex in the same app?

Yes. Both runtimes live in one workspace: Claude Code and Codex history is browsable and searchable side by side on every plan, including Standard, and you choose which provider a new conversation starts in. Every plan can keep several live conversations running at once. Handing work between Claude Code and Codex and keeping multiple provider accounts separate are Pro or Premium. Crowsnest coordinates the runtimes already installed on your machine rather than replacing them. Using both agents in one app →

Is it allowed to use more than one Claude or ChatGPT account?

Holding separate accounts you are entitled to, such as a personal subscription and one your employer or a client provides, is ordinary practice, and keeping those apart is what Crowsnest’s multiple accounts are for. Creating extra accounts to get around the usage limit of a single subscription is a different thing, and it is the sort of use providers restrict. Crowsnest never pools quota: each account keeps its own login, limits, and bill. Read Anthropic’s and OpenAI’s current terms for your plan before you rely on any arrangement.

Can I move a task from Claude Code to Codex?

Yes, on Pro or Premium. Two agent runtimes cannot share one thread, so a handoff is an explicit, attributed fork rather than a native resume: Crowsnest writes a bounded briefing that quotes the work so far, starts the new provider-native conversation, and keeps the lineage visible on both sides. Quota is never pooled, and each side still bills to its own provider account. What a handoff briefing should quote →

Do I need an account or a license server?

The official macOS app requires a Google or GitHub account. The first sign-in starts one fixed seven-day trial. Standard, Pro, or Premium is required after it ends. Signed access is verified locally, and a current cached document works offline with no payment polling during ordinary use.

Does Crowsnest run the agents for me in the cloud?

No. Crowsnest coordinates the Claude Code and Codex runtimes installed on machines you control; those providers still execute models under your own plans. There is no Crowsnest cloud and no queue.

Does Crowsnest show a Claude Code and Codex usage summary?

Yes. Every plan shows the current provider window's usage and spend. Pro and Premium Insights add local usage summaries across 7, 30, 90, or 365 days or all recorded history, with supported breakdowns by project, model, hour, cache behavior, and conversation. Unsupported dimensions are omitted, and values are labeled by provenance rather than presented as a billing ledger.

How are paid Crowsnest features unlocked?

Standard is a $19.99 one-time purchase, Pro is a $69.99 one-time purchase, and Premium has a $99 one-time launch price, 50% off $198. A successful Polar payment assigns the chosen plan to the same email used for Crowsnest sign-in. After checkout, Refresh now obtains a signed document that the local server verifies before opening the paid workspace boundaries.

Does the price include model usage?

No. A Crowsnest plan covers the local workspace only. Claude Code and Codex still execute models under your own provider plans, and you need at least one of those plans for Crowsnest to be useful.

How do I contact support?

Email support@crowsnest.app for help with installation, sign-in, or a purchase. Crowsnest still uploads nothing on its own, so include the Crowsnest and macOS versions and only the details you choose to send.
