As answered by people managing Extism 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.

Technically WASI 0.1, but I used it (via Extism[0]) to implement a simple login library[1] that works in Rust, Go, and Node. Would be trivial to add other lanugages supported by Extism. Overall I loved the dev experience. [0]:... - Source: Hacker News / 3 months ago
I tinkered with https://extism.org and basically the use case is that they suggest, namely you can extend software in another programming language but without having to setup a container or VMs on the client. They "just" run the code in... - Source: Hacker News / 3 months ago
Check out https://extism.org, it is built for those kinds of use cases. However I think WASI and components could enhance it. - Source: Hacker News / 3 months ago
