Show HN: Accessyo – CLI to Debug DNS, TCP, TLS and HTTP Issues

I kept running into “works for me, not for users” issues, where everything looked fine locally but failed somewhere along DNS / TCP / TLS / HTTP.

So I built a small CLI tool that checks each layer step by step and shows where it breaks.

Example:

DNS (NXDOMAIN) → domain does not exist

It’s meant to quickly narrow down the problem instead of guessing.

You can run it directly via:

npx accessyo yourdomain.com

It’s free and open source.

Would love feedback from people who deal with these kinds of issues.
