AI coding agents,
on your phone.

OpenDev gives you a cloud dev server with an AI coding agent, driven entirely from your browser — build, fix, and ship from anywhere.

Get started See how it works

Everything you need to code from anywhere

No laptop, no setup — just a browser.

📱

Mobile-first

A terminal and chat interface designed for phone screens first. Everything works great in a mobile browser — install it as an app.

🤖

Real AI coding agents

A full agentic coding tool runs on your server — it reads, writes, and runs code, not just autocomplete. Free models included; bring your own API key for more.

☁️

Your own cloud server

Each workspace is a real dev environment in the cloud — Node, Python, git, and common dev tools, with your data persisted across restarts.

🔒

Private & secure

Sign in with Google, HTTPS everywhere, and isolated sandboxes per workspace. Your code and keys stay yours.

Reminders & Telegram

Ask the agent to remind you about anything — it pings you on Telegram. Kick off work from chat and come back when it's done.

🔧

Open by design

Built on open-source tools — an open agentic coding CLI, tmux, and a web terminal. No lock-in: it's your server and your code.

How it works

From zero to coding in a couple of minutes.
