Original Summary

Most online developer tools are fine for simple things, but I kept getting frustrated whenever I needed to dig a little deeper. A TLS checker that only shows the certificate. A DNS checker that hides the actual response. An email checker that says SPF is broken without showing where the 10 DNS lookups went. So I started building my own. kirkdiamond.com is now a growing collection of free developer and infrastructure tools for DNS, TLS, HTTP, email, networking and the usual developer utilities. A few of the things I've focused on: TLS checks that make a real connection and inspect the chain, protocol versions, SNI, ALPN and expiry DNS lookups with real record data, TTLs and resolver selection SPF analysis that recursively expands includes and counts DNS lookups HTTP inspection with redirects, headers and DNS/TCP/TLS/TTFB timing A Domain Health check that combines DNS, TLS, HTTP and email security into one report Browser-side tools for things like JSON, JWT, hashing and encoding where sensitive input doesn't need to leave the browser There is no account required. I wanted the site to be something where you can land on a tool, get the answer, and leave. It's still very much a side project and I'm continuing to add to it. The video shows a few of the tools running. I'd especially love feedback from other developers on one thing: what diagnostic/debugging tool do you regularly Google for that still annoys you? https://kirkdiamond.com   submitted by   /u/Lord-kirk [link]   [comments]
