Frequently asked questions
Do these tools make requests on my behalf?
Status checker and header inspector do. Other tools run entirely in your browser.
Are requests logged or stored?
No. Requests are made directly from your browser to the target server. We never proxy or store them.
Can I check sites that block my IP?
Yes. Status checker uses your browser's connection, so it sees what you see.
Do these tools work for HTTPS sites?
Yes. All tools support both HTTP and HTTPS endpoints.
Is there a rate limit?
No hard limit, but please don't hammer public APIs. Be considerate of target servers.
