Hey Product Hunt! I'm Ethan, the one-person team behind Patchen Technologies. I built Probe Toolkit because I was tired of bouncing between MXToolbox, dnschecker.org, and five other tabs just to diagnose a single DNS issue. So I built one place that does it all. The feature I'm most proud of: paste anything into the search bar. An IP address, a domain, a JWT token, a MAC address — it detects what you pasted and fires every relevant tool in parallel. One paste, every answer, one page. A few things I care about: - Privacy first — client-side processing wherever possible. Your data doesn't leave your browser unless a server lookup is required, and nothing is ever logged. - No signup wall — every tool is free, right now, no account needed. - No bloat — vanilla JS and PHP, zero frameworks. Pages load in under a second. There are 42 tools live today across DNS, network, email, web, security, and developer categories. I'm actively building and would love to hear what tools you'd want to see next. Happy to answer any questions!
