Your keys, your server
Every crossposting service asks you to hand over write access to your social accounts. Postline is the same software, running on your own box, with the tokens in your own database.
Tokens never leave your instance
OAuth tokens and app passwords are stored encrypted in your database, with a key only your instance holds. There is no vendor with a copy.
One command to deploy
Postline deploys as a single Bun service. There is no queue cluster, no broker, and no separate worker fleet to keep alive.
More features
- Crossposting Write once and publish to Bluesky, X, LinkedIn, Instagram, Threads and Mastodon in a single pass.
- Scheduling Schedule posts ahead in your own timezone and let the queue publish them, or send immediately.
- Per-network variants Override the text for any single network without maintaining six separate drafts of the same post.
