Tracking Twitter/X unfollowers got significantly harder after 2023. X's API changes shut down most of the free tools that used to make this effortless, and the landscape has shifted considerably. Many tools that still rank on Google are either broken, paywalled, or worse — risky to your account.
This is an honest comparison of what actually works in 2026 for tracking Twitter unfollowers, ranked by safety and cost.
Why Most Old Twitter Unfollow Tools No Longer Work
Prior to 2023, Twitter's free API tier gave third-party apps access to follower lists, letting tools like JustUnfollow and Who.Unfollowed.Me provide real-time unfollow tracking. When X raised API access prices — to as much as $42,000/month for enterprise tiers — the vast majority of these tools died overnight or pivoted to paid-only models.
This means the landscape in 2026 is very different from what you'll find in most "best tools" articles that haven't been updated. Here's the honest current picture.
Quick Comparison
| Tool | Free? | No Login? | Still Works? | Safe? |
|---|---|---|---|---|
| FollowSweep | ✓ Free | ✓ Yes | ✓ Yes | ✓ Very safe |
| Circleboom | Freemium | Requires OAuth | ✓ Yes | ⚠️ Moderate |
| Followerwonk | Freemium | Requires OAuth | ✓ Limited | ⚠️ Moderate |
| Who.Unfollowed.Me | Was free | Requires OAuth | Mostly broken | Outdated |
| JustUnfollow | Paid | Requires OAuth | ⚠️ Partial | ⚠️ Varies |
Tool-by-Tool Breakdown
1. FollowSweep
FollowSweep works by analyzing your downloaded X/Twitter data archive rather than connecting to X's API at all. You download your followers.js and following.js files from X's data export, upload them to FollowSweep, and get an instant breakdown: who doesn't follow you back, who you don't follow back, and mutual followers.
- Completely free
- No Twitter/X login required
- Data never leaves your browser
- Not affected by API changes
- CSV export included
- Not real-time — requires re-download to update
- Shows current state, not history of who unfollowed when
2. Circleboom
Circleboom survived the API changes by becoming a paid product. Their free tier gives you very limited access — usually just a snapshot of your current followers. Unfollow tracking and history requires a paid subscription starting around $8/month. They use OAuth login (no password sharing, just account access permission).
- Real-time tracking (paid)
- Historical unfollow data
- Clean interface
- Requires OAuth account access
- Free tier very limited
- Monthly cost
3. Followerwonk
Followerwonk is primarily a follower analytics tool rather than a pure unfollow tracker. It's good for understanding your audience demographics and finding new accounts to follow. The unfollow tracking functionality is limited on the free plan and the tool has become less reliable since X's API changes.
- Good audience analytics
- Long track record
- Unfollow tracking limited/unreliable
- Requires OAuth login
- Paid for full features
What to Avoid
Several sites still rank for "Twitter unfollow tracker" but are effectively defunct — their APIs were cut off and they just show errors or cached data. Always check when a tool was last updated before trusting it.
The Bottom Line
If you want to check who doesn't follow you back on Twitter/X right now, the safest and most reliable free method is to use your data export with FollowSweep. It takes about 5 minutes and requires no account access from any third party.
If you need ongoing real-time tracking and historical data and don't mind paying, Circleboom is the most polished paid option that still works reliably in 2026.
