Open toolNothing you paste or analyse is saved. Pure JS tools run entirely in your browser. Proxy tools fetch, process, and immediately discard.
Open the tool, use it, close it. No account, no email, no cookie banner beyond the legal minimum. Just the tool.
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.
