See Voidbunny on your phone
Three agents, a real terminal, the same git checkout you’d have over SSH — sitting on a box you fully control, opening from your home screen like a native app.
Same shell, anywhere
A real terminal hooked to a real PTY on your box. Run the agent CLIs, edit dotfiles, tail logs — nothing's emulated.
Three agents, one app
Claude Code, Codex, Gemini — switch per project or use whichever one's on a streak. Sign in with the subscription account for each; no API keys needed.
PWA with Web Push
Add Voidbunny to your Home Screen and it behaves like a native app — including push when long agent tasks finish.
Everything that’s in the box
One installer, fourteen moving parts — every one of them an open tool you can already SSH into and inspect. No proprietary runtime, no managed control plane.

FAQs
A self-hosted web app that runs on your own machine — a rented Ubuntu VPS, an old desktop at home, whatever you have — and gives a coding-agent CLI (Claude, Codex, Cursor, Gemini, Grok) a real shell, a real filesystem, and a real git checkout. You open Voidbunny from your phone or laptop, type or speak a prompt, and the agent does the work on your box: branches, commits, deploys, the lot.
Voidbunny is the wrapper — the agents are still the agents. Sign in with the subscription you already pay for (Claude Pro / Max, ChatGPT Plus / Pro, Cursor Pro, Google AI Pro, SuperGrok) or drop in an API key. Voidbunny doesn't touch your credentials; they live in the CLI's own config directory on your box.
