Features
Run four agents side by side
Split the window into up to four panes and give each agent a different job. They work at the same time, and each pane keeps its own model and its own diff to review. Put each one on its own git worktree and they never touch the same files.

One sentence becomes an automation
Type the routine the way you would say it: "Every weekday at 9am, run the tests. If any fail, have an agent fix them, then wait for my approval before it opens a PR." Frink builds it as a Flow and lists every step, so you can read it and change it before it runs.

It starts when something happens
A new ticket in Linear, Shortcut or ClickUp, an error in Sentry, an event in PostHog or Vercel, any webhook, or a time of day. The Flow checks a condition to pick its path, and waits at an approval step until you say yes.

Everything that needs you, in one queue
Every run from every project shows up in the Work Queue as running, ready for review or queued. A badge appears when a Flow stops for approval or an agent has a question. Read what it did, then approve it or reply to send it back.

Check the work and fix it yourself
Every file the agent changes shows as a diff. Open it in the built-in editor, change a line and save, run a command in the terminal, or roll the chat and its code back to an earlier point.

Also in the box:
- Custom steps — need a step Frink doesn't have? Ask the agent to write one in JavaScript, or write it yourself, and reuse it in any Flow. For another language, use a command step.
- Plugins & MCP — connect Linear, Shortcut, ClickUp, GitHub, Notion, Slack, Sentry, PostHog and more, as chat tools and Flow steps.
- Your own AI sign-in — uses your existing Claude Code or Codex login, the OpenCode or GitHub Copilot you installed, or your Cursor sign-in. Frink only checks that you are signed in and leaves the login with the tool. If you paste an Anthropic API key instead, it is stored encrypted on your computer.
- Local-first — chats, Flows and tasks live in SQLite on your machine. No account needed. Official builds send anonymous usage counts and crash reports: everything Frink sends.
Supported Agents
Bring your own subscription or API key — Frink runs the agent, you keep the account.
Install
Linux (x64 and arm64)
Download the AppImage or the .deb from frink.dev/download, or directly: x64 AppImage · .deb, arm64 AppImage · .deb. Both update themselves.
- AppImage (any distro):
chmod +x Frink-X.Y.Z.AppImage && ./Frink-X.Y.Z.AppImage, with X.Y.Z the version you downloaded. It does not need libfuse2: it mounts itself with fusermount3 from the fuse3 package. If it will not start, install fuse3 or start it with --appimage-extract-and-run. Keep it in a folder you can write to, such as ~/Applications, so updates can replace it.
- .deb (Debian/Ubuntu):
sudo apt install ./frink_X.Y.Z_amd64.deb (_arm64.deb on arm64). Updates ask for your password in a system prompt.
Frink saves API keys and MCP credentials only when it can encrypt them with a desktop keyring (GNOME Keyring or KWallet). Without one it does not save them, so install one and relaunch Frink before adding accounts.
