Cloudflare acquires Deno to improve its Workers programming model
Internet infrastructure company Cloudflare announced on Friday that it is acquiring Deno, the startup behind the programming runtime of the same name. The deal is meant to improve the Cloudflare Workers platform for building and running software.

Cloudflare, a US company providing network and internet infrastructure services, said on Friday, October 10, that it is acquiring the startup Deno, which develops a programming runtime of the same name used to run software. The financial terms of the deal were not disclosed.
According to Kenton Varda, principal engineer for Cloudflare Workers, the company will use the acquisition to improve the Workers programming model and platform. Workers lets customers build and run software on Cloudflare's network.
Open source Workers implementation
Deno was co-founded by Bert Belder and Ryan Dahl, the creator of Node.js. The company recently released celld, an open source implementation of Workers, which Varda wrote "delighted" the Cloudflare team.
Varda also addressed what he called a popular theory that Cloudflare made Workers work differently from other cloud platforms in order to create "lock-in" for customers. He rejected it, saying the company believes that being open source and giving people an escape hatch is good business.
Dahl, for his part, wrote that his team is joining Cloudflare to make the Workers programming model a mainstream way to build servers.
Funding
Deno had raised a total of $26 million, including a Series A round led by the venture capital firm Sequoia.
