Cloudflare said it is acquiring Deno, the startup behind the Deno runtime. Cloudflare principal engineer Kenton Varda said the deal will improve the Workers programming model and platform, and he praised Deno's recent open-source Workers implementation, celld. Deno co-founder Ryan Dahl said his team is joining Cloudflare to make the Workers programming model a mainstream way to build servers; financial terms were not disclosed.

Expanded Detail

Cloudflare disclosed on Friday that it will take over Deno, the company behind the JavaScript/TypeScript runtime? Wait material says programming runtime of same name. It doesn't specify JS/TS. Avoid inventing. Deno was started by Bert Belder and Ryan Dahl, the latter known for creating Node.js. The startup had raised $26 million overall, with Sequoia leading a Series A. Terms of the purchase were not made public.

Cloudflare principal engineer Kenton Varda said the deal will refine Workers, its system for letting customers run software across Cloudflare's network. He pointed to Deno's new celld, an open-source Workers implementation, as a development the Cloudflare team welcomed. Varda also rejected the idea that Workers was designed to trap users, saying open source and an exit path make business sense. Dahl said his team will join Cloudflare to push the Workers model toward mainstream server building.

Context

1 paragraph measured analysis. Could use general knowledge. But no political advocacy. Fine. Maybe avoid "serverless/edge" if not in material? It's okay as wider topic. But maybe "cloud and developer platforms" safer. "developers and businesses that use Cloudflare Workers or similar cloud platforms" affected. "Open-source maintainers and startups in runtime ecosystem" okay. "deploy code closer to users" edge inference. Could be okay. Need under 90. Good. Need output ONLY two labeled sections. Exactly format: EXPANDED: ... CONTEXT: ... No extra. Ensure no markdown? Plain text. Good. Need maybe "EXPANDED:" and "CONTEXT:" labels. The expanded section must be 2 short paragraphs under 120 words total. We have two paragraphs. Good. Need no copying source phrasing. Check phrases: "Cloudflare said Friday it will acquire Deno" source "Cloudflare announced Friday that it’s acquiring Deno" similar but original enough? Maybe "said Friday it will acquire" is close.
