Users migrating from traditional social networks to Bluesky want to rebuild their social graph. This extension automates discovering which accounts they follow on other platforms also exist on Bluesky, then lets them bulk-follow, block, or import those users into Bluesky lists.

1. User opens a following/followers/blocked/list page on a supported social network (X, Threads, Instagram, TikTok, Facebook). 2. User presses Alt+B or clicks the toolbar icon to open the extension popup. 3. User signs into Bluesky via OAuth or App Password. 4. Extension scans visible users on the page, matching them to Bluesky accounts. 5. User views detected matches in a results modal. 6. User can bulk follow, bulk block, or import matched users into a Bluesky list.

Target users: Users migrating from X/Twitter to Bluesky / Users migrating from Threads, Instagram, TikTok, or Facebook to Bluesky / Social media users wanting to rebuild their follow graph on Bluesky

Source files are minified/bundled (Plasmo framework build), making deeper code inspection of auth flow and API calls difficult, but locale strings and manifest provide strong evidence.
The exact OAuth implementation details in the background service worker are obscured by bundling.
Cannot confirm whether Bluesky itself has any paid tiers that affect this extension's functionality (Bluesky is currently free).

Monetization

No paid features detected

No paid features, subscriptions, or payment gates found in the extension. No premium/subscription/stripe/payment/upgrade/plan keywords in meaningful context. The only money-related reference is a voluntary 'donate_message' linking to ko-fi.com/kawamataryo (individual developer tip jar), which does not gate any functionality. All 'pro' keyword matches are false positives (Proceed, Processing, profile URLs). The extension appears fully free with optional donations.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension requires signing into Bluesky to use its core workflow. Two login methods are provided: (1) OAuth via 'Sign in with Bluesky' button that redirects to server.sky-follower-bridge.dev OAuth flow, and (2) App Password with handle/email + app password + service URL. Without Bluesky authentication, the extension cannot follow, block, or import users to Bluesky. The store description explicitly states: 'Sign in with Bluesky (click the button to open Bluesky and authorize the extension)'. The manifest includes the 'identity' permission for Chrome OAuth.
