📎169 free DNS, email, TLS diagnostics in one place + more!
5 followers
169 diagnostics for the boring-but-critical layer of the internet: DNS records, email authentication (SPF · DKIM · DMARC), TLS certificates, IP blacklists and HTTP security headers — plus in-browser dev utilities (JWT, cron, regex, hashing) where your data never leaves your machine. No sign-up to run a check. Built by a self-hoster who got tired of juggling six sites to debug one mail server. Watchlists, cert/DNS expiry alerts, embeddable badges and an API on top.
Hey Product Hunt!
I run my own mail server, and if you've ever tried that, you know the drill: mail silently lands in spam, and the answer is scattered across a DNS checker here, a blacklist lookup there, an SSL tool somewhere else. I built bypassed.me to put every check in one place — it's grown to 169 tools covering DNS, email auth (SPF/DKIM/DMARC), TLS, IP reputation, plus a pile of dev utilities. The client-side ones (JWT decode, hashing, etc.) run entirely in your browser, so real tokens and keys never touch a server. 👍
Free tier needs no account — just run a check. I'd love to hear what's missing: tool requests are the fastest thing for me to ship.
🧰 All-in-one (1) — every applicable check on one domain, one graded report
🌐 DNS (13) — records, propagation, DNSSEC, subdomain enum via CT logs, reverse
📧 Mail (28) — SPF, DKIM, DMARC, BIMI, MTA-STS, TLS-RPT, SMTP banner, header analysis, spam score, plus record builders
🔒 TLS (14) — cert details, full chain (leaf → root), expiry, HSTS preload, cipher/config grading
⚡ HTTP (9) — security-header grading, ping with latency stats, redirect trace, OG preview, port check
📍 IP & WHOIS (11) — DNSBL across common blocklists, WHOIS, ASN/geo, CIDR + OUI calculators
🧹 Web hygiene (22) — cookie flags, CSP grading, robots.txt, security.txt, CSR generator, typosquat finder
🛠️ Utilities (44) — JWT decoder, Base64, JSON formatter, regex tester, cron explainer, UUIDs, diff, timestamps…
🔐 Cryptography (27) — hashing, HMAC, AES & RSA, PEM↔DER, SSH keys, bcrypt, plus wallet-address validation (BTC/ETH/XMR checksums, Lightning address, BIP-353)
The utilities + crypto ones run entirely in your browser — nothing you paste ever leaves your machine.

ran a quick check on my own domain and was surprised how fast it pulled the full picture. love that no login is needed and the dev tools run locally.
