Cert Decoder is a free online tool that helps you decode X.509 SSL/TLS certificates in PEM format. It instantly shows important information like the issuer, expiry date, SAN entries, and fingerprint. All data is processed locally in your browser, so nothing is ever sent or stored elsewhere.
HTML Hoster publishes your HTML, images, PDFs, ZIPs and Markdown to the web as instant shareable links — no server setup, no build step. Drop in an HTML file for a clean htmlhoster.com/p/... URL, host images, turn any PDF into a link, unzip and serve archives, or convert Markdown to a live page....

As answered by people managing Cert Decoder and HTML Hoster.
Cert Decoder's answer
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
HTML Hoster's answer:
HTML Hoster started from the gap between "I have an HTML file" and "here's a URL anyone can open." Static hosts assume you want a whole project and a deploy pipeline; sometimes you just want one file online now. So we built the shortest path from drag-and-drop to a shareable link, with object storage doing the heavy lifting and no database in the way.
Cert Decoder's answer
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
HTML Hoster's answer:
api.htmlhoster.com) handling uploads, scanning and takedownsCert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
HTML Hoster's answer:
Anyone who needs a live link to a file without running infrastructure: developers shipping demos and prototypes, marketers running quick landing pages, educators and students hosting project work, and automation that needs to publish via the agent API. It's built for speed and zero setup rather than long-term site hosting.
Cert Decoder's answer
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
HTML Hoster's answer:
Most hosts make you provision a server, wire up a domain, or sit through a build step. HTML Hoster skips all of it: drop a file in and you get a URL. There's no account wall for basic use, uploads are protected by Cloudflare Turnstile to block abuse, and a reported-content workflow keeps the platform safe without slow pre-moderation. Free to start, instant to share.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
HTML Hoster's answer:
HTML Hoster has no traditional enterprise accounts — it's a free, low-friction tool with no sign-up wall, so "customers" are best described as user groups rather than named logos:
HTML Hoster's answer:
HTML Hoster lets you publish any HTML, image, PDF, ZIP or Markdown file to the web as a clean htmlhoster.com/p/... link in seconds — upload a page, host images, turn a PDF into a link, or convert Markdown to a live page. Files are stored directly on object storage and never pass through a database, so what you upload is exactly what gets served. It also ships an agent API for programmatic publishing.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
