Cloudflare announced Friday it is acquiring Deno, the startup behind the programming runtime of the same name, to improve its Workers platform.

What Deno brings to Workers

Deno, co-founded by Bert Belder and Node.js creator Ryan Dahl, recently launched celld, an open source implementation of Workers that Cloudflare principal engineer Kenton Varda said delighted the team.

Varda argued that contrary to popular theory, Cloudflare did not make Workers work differently to create lock-in, saying being open source and giving people an escape hatch is good business.
