Sky Follower Bridge
Browser extension that finds your Twitter/X contacts on Bluesky — migrate your professional network without starting over.
What should journalists know about Sky Follower Bridge?
Sky Follower Bridge solves a real problem for journalists leaving X: finding the colleagues, sources, and organizations you already follow on Bluesky. Install the extension, visit your X follower/following list, press Alt+B, sign in with Bluesky OAuth, and it scans for matching accounts. It works across Chrome, Firefox, and Edge. The matching isn't perfect — it searches Bluesky's API for similar usernames and display names, so you should verify each match before following. v3.1.0 added support for self-hosted Bluesky PDS servers. The extension has 863 GitHub stars, is MIT-licensed, and the code is readable. It authenticates to Bluesky via OAuth or app password — your X credentials are never touched (it just reads the public follower list displayed in your browser). Rate limiting from Bluesky's API can slow down large migrations. Built by kawamataryo, a solo developer active on Bluesky.
Migrating your X/Twitter following list to Bluesky. Finding journalist colleagues who've moved to Bluesky. Rebuilding professional networks after platform shifts. One-time migration rather than ongoing use.
Automated cross-posting between platforms. Managing multiple Bluesky accounts. Mobile browsers (desktop only). Ongoing follower synchronization — it's a one-time migration tool.

Privacy policy summary
The extension runs locally in your browser. It reads your X follower lists from the page you're viewing (no X API access needed) and queries Bluesky's public API for matches. Authentication is via Bluesky OAuth or app password — your X credentials are never requested or accessed. No data is sent to third-party servers beyond Bluesky's API. No analytics or telemetry in the extension code.
How to protect yourself:
Use Bluesky OAuth rather than app passwords when possible — OAuth is more granular and revocable. Review each suggested match before following — the matching algorithm can produce false positives. Be aware that bulk following via 'Follow All' may trigger Bluesky rate limits. Review the extension's permissions in your browser before installing.
Open-source under MIT license with readable code. Runs locally in the browser with no third-party data collection. The main trust consideration is that it authenticates to your Bluesky account — use OAuth rather than app passwords for better security. Solo developer project means slower security response if issues arise, but the codebase is small and auditable.
Who Owns This
Known issues
Matching accuracy varies — false positives occur when usernames or display names are similar but refer to different people. Bluesky API rate limits can interrupt large migrations (wait 2-3 minutes and retry). Solo developer project — bus factor of one. Desktop browsers only, no mobile support. 'Follow All' button can trigger aggressive rate limiting if used on large lists.
