Mobile IDE
Making software doesn't need a bigger screen.
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.
