A tray app for Windows and Linux
The inbox for your coding agents
foolscap lives in your tray, tells you the moment Claude Code, Codex or any ACP agent needs you, and sends each agent's next prompt only when your tests pass.

Queue the next prompt
Give any task its “then…” steps when you start it, or while it works.
- 2
Your repo's tests run
When a turn ends, foolscap runs your own test command itself, outside the agent's sandbox.

Sent only on green
Green sends the next step. Red holds it and tells you why. You can always send anyway.
The pill
Answer without switching windows
A small capsule floats above your taskbar with one mark per task: a dot when one needs you, a ring while one works. Hover it to approve, deny or merge right there.
- On Windows the notification itself has Approve and Deny, and takes a reply.
- Claude Code sessions you start in your own terminal show up too, approvals included.
The orbit
Urgency as distance
Click the pill and the orbit opens: you in the middle, every task a planet. Whatever needs you sits closest; finished work drifts to the edge.
- Tab walks the planets, A approves, D denies, Esc puts it away.
- Each task keeps its place, so the picture never reshuffles under you.
The queue
The next prompt waits for green
Give a task its “then…” steps. After each turn foolscap runs your repo's own tests, outside the agent's sandbox, and sends the next step only when they pass. Red or unclear holds the queue and tells you why.
- Green means exit code 0 and at least one test that actually ran, read from the runner's own counts.
- Every task gets its own git worktree. Merge lands it as one commit; Discard throws it away.
Voice
Say the next step
Press the mic, talk, and foolscap writes it down as a clean prompt for the agent. Every licence comes with 2,000 voice words a week.
- foolscap Cloud keeps no audio, transcripts or prompts: only a hash of your licence key and a word count.
While you were away
Come back and the panel says what finished green, what went red and what is waiting for you. Counted from a local journal, never guessed.
Your settings, or none
Start Claude Code with only the repo's own settings, or with your CLAUDE.md. foolscap never reads or stores your agents' logins.
Personal assistants too
Hermes and OpenClaw connect over ACP like any agent. Their queue always waits for you.
Open source
The whole app is GPL-3.0 on GitHub. Build it yourself and it is never gated.

Download
Get foolscap
You need at least one agent installed: Claude Code, Codex, or any agent that speaks ACP.
Builds come from GitHub Releases.
Is it free to try?
Yes. Download it and every feature works for 14 days, with no account and no card. After that it asks for a licence key; building it yourself from the source is free and never asks.
What happens when the trial ends?
Your tasks and settings stay where they are. Starting new tasks needs a licence: $19 once, or $9 if you are one of the first 50 buyers. There is no subscription for the app itself.
How do I get my key?
Right after checkout it is on the thank-you page, and Dodo Payments emails it to you as well. Open foolscap, go to Settings, paste it under Licence and press Activate.
Does foolscap see my code or my agent logins?
It runs your own claude and codex on your computer, the same way you would in a terminal. It never reads, stores or sends your agents' logins or API keys, and your code never leaves your machine through foolscap.
Which agents does it work with?
Claude Code and Codex natively, plus anything that speaks the Agent Client Protocol: OpenCode, Goose, Qwen Code, Kimi, Copilot CLI, Kiro, and personal assistants like Hermes and OpenClaw. foolscap only shows the ones it finds installed.
What counts as “green”?
foolscap runs your repo's own test command after each turn, outside the agent's sandbox. It counts as passing only with exit code 0 and at least one test that actually ran, read from the runner's own summary. Zero tests, a missing exit code or a sandbox block is never green, so the queue holds and tells you why.
Is it really open source?
Yes. The whole app is on GitHub under GPL-3.0. The official installers need a licence after the 14-day trial; a build you make from the source is never gated.
What happens to my voice?
Your audio goes through foolscap Cloud to a speech service that turns it into text. foolscap Cloud keeps no audio, transcripts or prompts: only a hash of your licence key and how many words you used, so it can count your allowance.
How many computers can I use?
A licence works on 3 computers at once, and keeps working for 7 days offline. You can move it from one computer to another whenever you like.
Is there a Mac version?
Not yet. foolscap is built for Windows and Linux first, where nothing like it existed.
Your agents, one tray away
Stop checking terminals. foolscap tells you when it is your move.
