Layer-by-layer network diagnosis when curl and dig already exist separately.

Strengths

•Sequential DNS→TCP→TLS→HTTP checks with clear failure point identification
•Batch mode groups multiple domains by failure type for quick triage
•JSON output enables CI/CD and monitoring integrations

Weaknesses

•Marked work in progress, not fully published to npm yet
•Competes with established tools like curl, dig, openssl s_client

Post Description

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.

Scanward – Free domain security scanner (SSL, DNS, headers, email auth)

Putting SSL, DNS, HTTP headers, SPF/DKIM/DMARC and uptime into one external scanner is the kind of boring-but-critical product people actually pay for; Scanward adds continuous monitoring, instant alerts and a free no‑signup scan which lowers friction. What will decide adoption is the scoring transparency and integrations — the product is convenience-first, not a deeper replacement for specialized tools like Hardenize or SSL Labs.
