A FOCUSED WORKFLOW
From a long list
to a useful one.
One desktop window. Load your trackers, run a check, then copy or save exactly the selection you want.
Read the response
Check availability or add a magnet or torrent file to see seeders and incomplete peers for each tracker.
Export the keepers
Exclude failed checks and, optionally, zero seeders or peers. Copy the clean list or save a TXT. Your input stays intact.
THE DESKTOP APP
The response is the result.
A working tracker must return a valid BitTorrent protocol reply. An open port or a successful web request is not enough.
Working
A valid protocol response.
Review
Answered, but needs attention.
Failed / Invalid
This check failed, or the URL is unsupported.
CLEAR BOUNDARIES
Tracker diagnostics.
Nothing to download.
Tracker Radar queries trackers. It does not connect to discovered peers, join DHT, or download torrent content.
Unknown stays unknown
Missing statistics appear as a dash, never an invented zero. Review entries require an explicit choice before export.
Private torrents stay scoped
Private torrent files are queried only against their embedded trackers. Use the original torrent file: magnets cannot reliably identify a private swarm.
Your connection, your check
No account, backend or telemetry. Trackers still see your IP address and any hash you query. Counts from different trackers are not unique swarm totals.

A FEW DETAILS
Before you start.
Does this make a torrent download faster?
It helps identify trackers that respond from your connection. Download speed still depends on the swarm, your network and your client. More trackers do not guarantee more unique peers.
What does “Peers” mean?
Incomplete peers reported by that tracker for the requested hash. Seeders have the complete content. The app keeps each tracker's counts separate.
Is a failed tracker permanently offline?
No. A timeout can depend on your connection or the tracker at that moment. Retest before treating a failed response as a permanent outage.
Can I use the exported list in qBittorrent?
Yes. Copy the clean list or import the saved TXT into your workflow. Tracker Radar does not modify your client. Private tracker URLs can contain passkeys; keep those exports private.
