Write once. Post everywhere. Schedule anything. Cross-post to X, Reddit, Telegram, Discord, and Bluesky — from a single self-hosted dashboard. No subscriptions. No data harvesting. Your keys, your server, your data.
| X (Twitter) | |
| Telegram | Discord |
| Bluesky |
Post to all five from one form. Right now, or on a schedule.
- Compose once, post everywhere - one form, five platforms, zero repetition
- Schedule with confidence - jobs persist across server restarts (MongoDB-backed)
- Smart retry - only failed platforms are retried; successful ones never re-post
- Live previews - see how your post looks on X, Reddit, Telegram, Discord, and Bluesky before sending
- OG link previews - paste a URL and metadata is auto-fetched (title, image, description)
- Character counters - real-time per-platform limits so you never go over
- Edit & Unschedule - change your mind before it goes live
- Media uploads - attach images directly from the dashboard
- API-first - the FastAPI backend works standalone; connect any client you want
- Rate limited & secure - API key auth on all endpoints, SSRF protection baked in
