As answered by people managing JSFiddle and ExpiryPulse.dev.
ExpiryPulse.dev's answer:
ExpiryPulse goes beyond SSL certificates to track any credential that expires — API keys, tokens, licenses, and certifications — all in one dashboard. Most competitors only monitor SSL. ExpiryPulse also includes SSL auto-scanning, CSV bulk import, allows assignment to a backup, and a genuinely useful free-forever tier with no credit card required.
ExpiryPulse.dev's answer:
ExpiryPulse was built to address the visibility and accountability gap around expiring certificates, API tokens, and credentials. Outages that could have been prevented with a simple alert kept happening because existing tools only tracked SSL certificates. ExpiryPulse was built to provide a single pane of glass for all credentials owned by a team.
ExpiryPulse.dev's answer:
ExpiryPulse is the only credential expiry tracker built for IT admins and small teams who manage more than just SSL certificates. It combines automated SSL scanning, multi-credential tracking, and timely alerts at 30, 14, 7, and 1 day before expiration — at a price point that makes sense for individuals and small teams, with a free tier that doesn't require a credit card.
ExpiryPulse.dev's answer:
Solo IT administrators, small IT teams, and MSPs who manage credentials across multiple services and can't afford to discover an expiry after the outage has already happened.

Test your javascript, CSS, HTML or coffeescript online with jsfiddle code editor. Jsfiddle – code playground.
JSFiddle cannot be used to host code on your server. The code has to be on JSFiddle and is public all the time.
What is missing from JSFiddle is live previews. You have to basically refresh the page by clicking on the play button. And compared to other playgrounds, JSFiddle is probably the slowest. Another slightly frustrating...
