Touitomamout is a lightweight crossposting tool that synchronizes tweets from Twitter/X to Mastodon and Bluesky. It is implemented in TypeScript for Node.js and distributed as a Docker image. The project is archived and no further updates are planned.

Key Features

Crossposts tweets to Mastodon (via masto.js) and Bluesky (via atproto) from a Twitter/X source
Available as a prebuilt Docker image for simple deployment
Can run on a schedule (cron-style scheduling) to perform periodic synchronization
Handles basic media and text payloads when creating posts on target platforms
Built with TypeScript and Node.js; CI/CD configured via GitHub Actions

Use Cases

Mirror a Twitter/X account to a Mastodon instance for audience migration
Publish selected Twitter/X content to a Bluesky account automatically
Run as an automated service on a home server or container platform to maintain cross-platform presence

Limitations and Considerations

The project is archived and receives no further updates; compatibility with evolving platform APIs is not guaranteed
Functionality depends on third-party APIs and scrapers; changes to source or target platform APIs may break synchronization

Touitomamout provides a straightforward, containerized way to crosspost tweets to federated networks, suitable for users who need a low-effort bridge between platforms. Evaluate compatibility with current platform APIs before deploying.
