Open source
The clients are public. The API is the product.
We build CatCaster in the open wherever someone else has to trust it. The SDK, the n8n node, and the Zapier app are MIT. Make imports the same public spec. Read the code, fork it, and ship with it.
MIT
TypeScript SDK
Projects, drafts, schedules, and publishes — the same /api/v1 routes the product uses, in a small client you can read.
Read the project
MIT
n8n
List workspaces, create drafts, schedule, and publish from a self-hosted n8n workflow. The node talks only to the public API.

MIT
Zapier
Create drafts, publish posts, and subscribe to post lifecycle hooks. The Platform app is open so you can see exactly which API calls a Zap makes.

Open API
Make
Import the CatCaster OpenAPI spec into a Make custom app. Your scenarios call the same public API, with your key, under your control.

Why we publish this
CatCaster exists because we were tired of closed tools that would not show their work. The product still has a dashboard, a voice, and a calendar. The way other software talks to it should be boring and visible: one HTTP API, clients you can audit, and a license that lets you keep a copy.
If you improve a client, send it back. If you only need to read it before you paste an API key, that is enough. We will keep these repositories next to the product.
