Free, no account
Every tool we run, none of them behind a signup.
Check a proxy list line by line. Look up any address and the network behind it. Find out what your browser leaks before a site does. We build these because we run the network underneath them, and a proxy you verified yourself is a proxy you trust.

Questions
About these tools
- Are these tools really free?
- Yes. Every tool on this page runs without an account, without a card and without a trial clock. They exist because we run the proxy network underneath them: the same probes that keep our own pool honest are cheap to point at your list, and a person who can verify a proxy before buying one is a better customer than a person who cannot.
- Do I have to be an HProxy customer?
- No. Nothing here checks whether you have an account. Paste a list from any provider, or from a public list you found somewhere, and you get the same answer.
- Which tool should I start with?
- If you have a proxy list and want to know what is in it, start with the Proxy Checker: it returns alive or dead, speed, anonymity and exit country per line. If you want to know what a website sees when you arrive, start with the Connection Checker, which runs the address, leak and fingerprint tests together and gives you one verdict.
- Can my AI assistant use these?
- Yes. Every tool here has a keyless HTTP endpoint and a markdown doc written for a machine, and there is an MCP server that installs in one line for Claude, Cursor and Windsurf. The details are on the For AI Assistants page.
- Do you keep what I paste in?
- The checks run and the result comes back to you. We do not build a profile from the lists people paste, and we do not resell them. Full detail is in the privacy policy.
