Self-hosted social media auto poster on Cloudflare
Postwire is a self-hostable social media auto poster that runs as a Cloudflare Worker on your own account so packages, images and any optional metrics tokens never sit on someone else's servers.
What runs where
The hub is a single Cloudflare Worker with D1 for data, R2 for images, Queues for scheduling and KV for rate limits. Optional metrics tokens are encrypted with a key that lives only in your Worker secrets.
The Chrome extension runs on your Mac and talks to your hub; platform logins never leave it.
Self-hosted options compared
If you want a self-hosted scheduler with a visual calendar and many integrations, Postiz is open source and runs on your own server with Docker. Postwire is narrower: it is built for an AI agent as the operator, with a local extension that fills every platform for you to publish.
Running on Cloudflare means no server to patch; the trade-off is that you need a Cloudflare account.
Frequently asked
- Is Postwire open source?
- Postwire is in an internal-use phase and runs on its author's Cloudflare account; it is not published as an open-source project. Postiz is the open-source option in this space.
- What does it cost to run on Cloudflare?
- That depends on your Cloudflare plan and usage; a once-a-day package is a small workload, but check Cloudflare's own pricing for Workers, D1, R2 and Queues.
- Where are my platform tokens stored?
- Posting needs no platform tokens at all. If you add optional metrics credentials, static ones live in Worker secrets and rotating ones are stored in D1, encrypted with a key kept in Worker secrets.
