A Zapier alternative for marketing work that needs judgment
Zapier moves data between apps when something happens. Marketing work needs research, writing and review. Tin ships that work as open-source workflows your coding agent runs.

Zapier is the most widely used no-code automation platform, connecting thousands of apps through triggers and actions.
| the job | how Tin does it | workflow |
|---|---|---|
| Zaps that try to automate content | Planned drafts in your voice, with human review. | content.generate → |
| Zaps that try to automate outreach | Approved sends with reply-aware follow-ups. | outreach.email_campaign → |
| Getting set up | Your agent plans and sets up the systems from your codebase. | growth.onboarding → |
What Tin does not replace
Tin is not a clone. Here is where each one fits.
Zapier still does this better
- Trigger and action automation across thousands of apps.
- No-code building for non-technical teams.
Choose Tin when
You work with a coding agent and want marketing done, reviewed and recorded.
Stay with Zapier when
You need app-to-app automation that anyone on the team can build.
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
Can Tin and Zapier work together?
They do different jobs. Tin exposes its workflows over MCP and an API, so other systems can start runs.
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.
