Mobile IDE
Treena is an agentic coding environment for your phone. Describe a task, approve a plan or let it run, test, and push to GitHub, all without a laptop.
The idea
The phone is already the computer you never put down. It should be enough to ship real software.
Serious development was stuck on desks because the tools were. Cloud workspaces and coding agents change that. You steer. The machine does the heavy lifting. The screen size stops mattering.
Product
A real workspace. On a phone. #
Not a toy editor. Editor, terminal, files, and an agent that can use them, running in the cloud so your battery stays out of it.
- Plan or act
- Plan mode drafts steps you approve first. Agent mode edits, runs commands, and iterates on its own. One toggle.
- Any model
- Claude, GPT, Gemini, and more. Switch mid-task without losing your place.
- Cloud machine
- Builds and long jobs run remotely. Claude Code and your CLI tools work out of the box.
Models
Your agent. Your model. Your key. #
Plan a change before anything moves, or let the agent act. Switch models mid-task. First release is bring-your-own-key: OpenRouter, OpenAI, Anthropic, Codex, Claude Code, and more.

How it works
From prompt to pushed commit #
- 01
Connect a GitHub repo
Sign in with GitHub, pick a repository, and Treena clones it into a fresh workspace.
- 02
Tell the agent what you want
Describe a task in plain language. The agent edits files, runs commands, and shows its work.
- 03
Test, review, and push
Run tests, check the diff, then commit and push back to GitHub, still on your phone.

FAQ
Questions, answered #
- What's the best mobile coding IDE for developers?
- Treena is built specifically as a mobile coding IDE: a real editor, terminal, and git workflow paired with an AI coding agent that runs in the cloud. Instead of a scaled-down mobile editor, you get plan and agent modes, a full workspace, and the ability to push to GitHub, all from a phone.
- Can I actually write and ship code from my phone?
- Yes. Connect a GitHub repo, describe the task, and either approve a plan before it runs or let the agent work unattended. Tests, diffs, commits, and pushes all happen from the same phone session, no laptop required.
- Do I need a laptop to use Treena?
- No. Treena runs the workspace, builds, and long-running jobs on a cloud machine. Your phone is the control surface; the heavy lifting happens remotely, so battery and device specs don't limit what you can build.
- Which AI models and coding agents does Treena support?
- Treena is bring-your-own-key: connect OpenRouter, OpenAI, or Anthropic directly, or use account-linked agents like Codex and Claude Code. Switch models mid-task without losing context.
- How is Treena different from Cursor or Replit?
- Cursor is a desktop code editor with no mobile app. Replit runs in the browser with a companion mobile app for viewing and light edits. Treena is built mobile-first: the full plan/agent workflow, terminal, and GitHub push are designed to work from a phone screen, not a scaled-down view of a desktop product.
