Why Tesseract

Tesseract is a new kind of development machine. It lives in a container on your own server, runs Claude Code around the clock and answers to your phone. Ask for a change, approve it from your Lock Screen and download the build, wherever you are.

1.0Agents

Claude Code that keeps working when you put your phone down

Start a run from anywhere and follow every tool call, diff and test result as it streams in. Claude works inside your sandbox, with your repos, your toolchains and your tests.
