Express has 2 supported release lines; endoflife.date doesn’t track Fastify. Both are open source under the MIT licence. OSV.dev lists 11 advisories from the last 12 months for Fastify and none for Express.
Last checked against endoflife.date, npm, deps.dev, OSV.dev and CISA KEV.
Every value links to its source. Where a row doesn’t apply to one of them, the cell says why.

Minimal Node.js web framework
Node.js web framework with schema-based validation and a plugin system
From StackPrism’s curated notes. Pricing isn’t covered here: it changes often, so check each vendor’s pricing page.
Both are minimal Node.js web frameworks. Express is the older and more widely installed of the two (see the weekly downloads below); Fastify adds JSON Schema validation and serialization, an encapsulated plugin system and built-in logging, and runs Express middleware through an adapter.
Release lines and end-of-life dates come from endoflife.date, release counts from deps.dev’s publish dates, and advisories from OSV.dev, counted once per flaw even when it’s listed under several ids, and checked against CISA’s list of vulnerabilities known to be exploited. Status and incident history come from each vendor’s public status feed; licences from each project’s licence file or the vendor’s licensing page, linked in the table.
The data refreshes every few hours and the time it was checked is shown above. There’s no pricing and no overall winner: which one fits depends on your constraints. To see how the versions you actually run hold up, check your repo.
