CompTool
Check usernames.
Instantly.
CompTool checks Discord username availability at real speed, with proxy support and live results — built for people who need answers fast.
High-speed checking
Safely checks up to hundreds of usernames a minute without tripping rate limits or hanging.
Proxy support
Runs your own proxy pool with smart concurrency, so throughput stays fast and clean.
Discord webhook alerts
Get pinged the moment a username opens up — configurable per search mode.
Sniper mode
Locks onto a single target and alerts you the instant it becomes available.
14 search patterns
Random, dictionary, palindrome, dot-prefix and more — built-in generators for every style.
Live dashboard
Real-time speed, hits, and history in a clean desktop app — no browser tab required.
System tweaks
Optional built-in tweaks to clean up temp files, reset network settings, and tune Windows performance — separate from the checker itself.

CompTool only works with a proxy subscription — it does not check usernames using your own direct connection. We recommend DataImpulse, which is what this site and app were tested with.
