Bivy

Local coding agents that show their work. Anywhere.

Bivy is the open-source workspace for coding agents. It runs Claude Code, Codex, Pi, OpenCode and other agents on your own machine. Reach them from a browser or your phone, with the live session, its terminal, its approvals, and the app they're building right in the chat. Try it, mark what's wrong, and send it back.

Bivy is not another coding agent and not a cloud development machine. The agent stays local and does the coding with your model provider. Your repos, tools, databases, and services stay where they are. Bivy gives you remote access to all of it, plus live previews, automations, and review.

• Live previews. The running app beside the chat. Mark it, send it back, share it with someone who has no Bivy account.
• Automations. GitHub issues, failed CI, Linear, Slack, schedules, and webhooks start the work. It comes back as a preview link or a pull request.
• Any agent. Hit a usage limit? Fork the session to another agent, or let Bivy retry when the limit resets.
• Your machine, anywhere. Start at your desk, pick the session up on your phone. The machine dials out, so there are no ports to open, and session traffic is end-to-end encrypted.

Recommended: sign in at app.bivy.sh, then copy your personalized Connect a Machine command into a terminal on your Mac or Linux computer. It installs and enrolls the machine without another Bivy login. The browser connects automatically; choose a repository and send your first task right there.

Prefer starting from the terminal?

curl -fsSL https://bivy.sh/install.sh | bash  # install + guided setup
cd your-repo
bivy run claude                            # or codex, pi, opencode
bivy open                                  # continue in the web app (needs remote setup)

Bivy Cloud hosts the app, control plane, and relay—not the machines running your agents. Connect a Mac, Linux computer, or existing server and bring your own agent subscription, model API key, or local model. You can also self-host the entire remote-access stack.

Bivy is 0.x software. Claude Code, Codex, Pi, OpenCode, and Grok are the release-tested paths. Credential sync, resume, handoffs, approvals, and sandboxing depend on the runtime. See the runtime support matrix.

Don't just read the diff. Try the app.

Bivy lets you use what the agent built and show it what to fix, without a separate deployment step.

1. Ask for a change. The agent works in your repo with your existing tools and local services.
2. Try the app. Bivy finds the dev server the agent starts and opens it beside the chat: web apps, terminals, and desktop apps. Use the running app, not a screenshot of what the agent says it finished.
3. Mark what needs work. Press and hold anything in the preview to mark it, or drag to circle it, then say what you want. Mark another keeps separate notes separate. The marks go to the agent with the element and page context. No screenshots to paste.
4. Follow each note. Every mark stays in the chat as a pin that resolves itself: Changed when a later run changes what you marked, Element gone when it leaves the page, Done when you say so.
5. Review the next version. A new version waits on the preview pill instead of reloading under you. Take it when you're ready, compare before and after, inspect the diff and checks, and decide when the work is done.
6. Get a second opinion. Share a preview link for 1 hour, 1 day, or 7 days. Teammates and clients try the running app and leave notes without a Bivy account. Make it view-only, or Stop sharing to end every link at once.

On Bivy Cloud, preview delivery is built in: no per-app domains, certificates, public ports, or tunnels to configure. Self-hosters configure preview delivery once for their Bivy deployment, not for every app. The app still needs its normal build or dev-server setup, and the machine serving it must stay awake and online. These are development previews, not production hosting.

Share deliberately: anyone with a preview link can use that app, including its live backend, until the link expires or you stop sharing. Reviewer notes aren't sent to the agent automatically; you send them or explicitly allow agent access. Preview traffic uses HTTPS through the preview relay, not session end-to-end encryption; the relay operator can see it.
