A map of your product, written from the code
Tin reads the connected GitHub repository and writes the Code map section of project memory: every user-facing surface with its exposure, plans and gating, integrations and tech stack, each cited to file and line.

A Tin workflow is a repeatable job: declared inputs, a bounded run and a defined output. The steps below are what this one does, every time.
- 01Reads the selected repository.
- 02Lists every user-facing surface and how it is exposed and gated.
- 03Records integrations and the tech stack.
- 04Cites each entry to file and line in wiki/INDEX.md.
Have Tin map our product from the code, then tell me which surfaces have no plan gating.
What every workflow here comes with
Battle tested on real products
These are the workflows we run for real companies. Claw Messenger went from about $45 to $2,105 in monthly revenue in 124 days on them. Each one has declared inputs, bounded execution and tests, and anything public waits for your review.
See the case study →Open source: read it, fork it, self-host it
Apache 2.0. Every workflow is a folder in the repository: the steps it runs, the data it reads and what it is allowed to do. Change it, or run the whole system on your own machine.
Open the repo →Runs on the agent that already knows your product
Your agent already reads this code. The code map turns that into durable memory every other workflow can use.

Questions
Why does a marketing system need a code map?
Because marketing that misdescribes the product fails. Every later workflow reads the map, so content and QA describe what really exists.
Is my code copied into the map?
The map cites file and line and describes surfaces. It is not a copy of the source.
Is Tin really open source?
Yes. Tin is licensed under Apache 2.0 and the source is at github.com/tin-computer/tin. You can read every workflow, change it, and self-host the whole system.
Which coding agents can run Tin workflows?
Any agent that speaks MCP, including Claude Code, Codex and Cursor. There is also an API, and the same projects run in the browser at app.tin.computer.
Why run marketing from a coding agent?
Because it already knows your product. It has the repository open, so it fills workflow inputs accurately, reviews output against what the product really does, and can act on the results in the same session.
