X Heimdall

About

X Heimdall scans your entire following list on X (formerly Twitter) and shows you every account that isn't following you back — in seconds, not hours. No login tokens to paste, no shady third-party sites, no data leaving your browser. Ever.

  𝗪𝗛𝗔𝗧 𝗜𝗧 𝗗𝗢𝗘𝗦

  ✦ One-click scan — hit Scan and watch real-time progress as your full following list is analyzed
  ✦ Followers audit — see every account that doesn't follow you back, with avatar, handle, display name, follower count, and verified badge
  ✦ Single or bulk unfollow — remove one account at a time, or select dozens and unfollow them all at once
  ✦ Search & filter — instantly find any user in your results by name or @handle
  ✦ Export to CSV — download your non-followers list as a spreadsheet for record-keeping or further analysis
  ✦ Stop anytime — cancel a scan or bulk unfollow mid-process with one click

𝗣𝗥𝗜𝗩𝗔𝗖𝗬 𝗙𝗜𝗥𝗦𝗧
Unlike web apps that ask for your Twitter password or OAuth tokens, X Heimdall works entirely inside your browser using your existing X login session — no data is ever sent to external servers.

  • Zero external servers — no data is ever sent outside your device
  • No OAuth — no third-party app access to your account
  • Local storage only — scan results stay in Chrome's built-in storage
  • Minimal permissions — only requests access to x.com, nothing else
  • Open source (coming soon)

  Your data stays yours. Period.

  𝗔𝗖𝗖𝗢𝗨𝗡𝗧 𝗦𝗔𝗙𝗘𝗧𝗬

  Built-in rate limiting protects your account from triggering X's spam detection:

  • Automatic delays between API requests during scanning
  • Throttled bulk unfollows (one action per 800ms)
  • Rate-limit detection — if X throttles you, the extension pauses and tells you when to retry
  • Request timeouts and error recovery built in

  𝗙𝗥𝗘𝗤𝗨𝗘𝗡𝗧𝗟𝗬 𝗔𝗦𝗞𝗘𝗗 𝗤𝗨𝗘𝗦𝗧𝗜𝗢𝗡𝗦

  Q: Does this work with the new X / Twitter?
  A: Yes. X Heimdall is built specifically for x.com (formerly twitter.com) and works with the current 2025 version of the platform.

  Q: Will I get banned for using this?
  A: X Heimdall uses built-in rate limiting that mimics normal browsing speed. It does not spam the API or perform aggressive automation. That said, bulk-unfollowing hundreds of accounts in a short period is something you should do gradually.

  Q: Does it need my password?
  A: No. It uses your existing browser session — the same cookies your browser already has when you're logged into X. No passwords,
  no tokens, no third-party access.

  Q: How many accounts can it scan?
  A: There is no hard limit. The extension paginates through your entire following list. For large lists (5,000+), the scan may take several minutes due to rate-limiting delays.

  Q: Can I see who unfollowed ME?
  A: Not currently. X Heimdall focuses on identifying accounts you follow that don't follow you back.

  Q: Does it work on Twitter.com?
  A: Twitter.com redirects to x.com, so yes — it works regardless of which URL you use.
