🔒
No data stored

Nothing you paste or analyse is saved. Pure JS tools run entirely in your browser. Proxy tools fetch, process, and immediately discard.

🚫
No signup needed

Open the tool, use it, close it. No account, no email, no cookie banner beyond the legal minimum. Just the tool.

♾️
Unlimited usage

No daily limits, no "pro required" gates on the tools themselves. The speed checker uses Google's API which has rate limits, but those are Google's — not ours.
