About WebChecks

What WebChecks is

WebChecks is a set of free diagnostic tools for DNS, email, TLS, and networking. Every check runs live—real DNS lookups, real TLS handshakes—not cached data pulled from somewhere else. Results are never truncated or gated behind an account, and when a check can’t run, the tool says so instead of failing silently.

About the author

I’m Jason Howe. I run cloud infrastructure for a US-based MSP, and these are the tools I use for that work. I built them because I wanted one place for the checks I run constantly—and since they exist anyway, there’s no reason not to share them.

Some tools are marked as in development. Feedback and bug reports are welcome.
