An open-source HeyGen alternative that shows the real product
HeyGen puts an AI presenter on screen. Tin puts your product on screen: it captures the live app at phone size and renders a short-form demo with a hook, voiceover and word-synced captions.

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
Tin connects to Claude Code, Codex or Cursor over MCP. That agent has your repository open and knows your product, customers and voice, so it fills the inputs and reviews the output. You never brief a new tool from zero.

Questions
Does Tin generate avatars?
No. It records your real product. The optional narrator is an illustrated brand character.
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.
