Deno raises $21M to launch a completely managed runtime service

Deno, the event firm behind the eponymous Deno runtime, at the moment introduced that it closed a $21 million Sequence A spherical led by Sequoia that brings its whole raised to $26 million. In line with CEO Ryan Dahl, the brand new money might be put towards constructing out Deno’s industrial providing, Deno Deploy, whereas rising advertising and marketing operations and exploring new strains of enterprise.

Deno is a runtime for JavaScript, TypeScript and WebAssembly based mostly on the Rust programming language and the V8 JavaScript engine initially developed for Google Chrome and Chromium internet browsers. Co-created by Dahl, who additionally created Node.js, Deno goals to offer a “productive” and safe scripting atmosphere that can be utilized to handle servers, carry out scientific computations, and extra.

A prolific engineer, Dahl launched Deno in 2019 with Bert Belder, the co-founder of StrongLoop, an organization constructing instruments and companies on high of Node.js. “Broadly, the aim of the corporate is to additional the usage of JavaScript exterior of the browser,” Dahl informed TechCrunch in an e mail Q&A. “The principle drawback is how one can tame the huge complexity of numerous and distributed infrastructure that’s the internet.”

Dahl sees Deno as a continuation of Node.js, which lets builders use JavaScript for server-side scripting (i.e., operating scripts serverside to provide dynamic internet web page content material). Deno seeks to resolve Node.js’ lack of interoperability, and — not like Node.js — it’s optimized for serverless computing, the place cloud suppliers summary away server useful resource administration.

“You give [Deno] a JavaScript perform that takes a request and returns a response, and we are able to serve that at scale indefinitely at zero value — if it’s low site visitors,” Dahl defined.

Deno the corporate contributes to Deno the open supply undertaking, which already has tens of hundreds of weekly lively customers on GitHub. A full-time group of engineers works on Deno, addressing points and bugs and deploying new releases. However Deno additionally sells entry to the aforementioned Deno Deploy, a managed Deno service operating on high of a community with 33 areas around the globe.

Dahl sees Cloudflare Workers as most intently competing with Deno Deploy, adopted by Vercel, Netlify and Fastly. However Deno has notched a number of wins so far, together with a collaboration with Slack to develop the latter’s next-generation improvement platform.

Deno can be a member of an initiative between Node.js and Cloudflare to permit the switch of apps between Cloudflare Staff, Deno and Node.js with out the necessity for a rewrite, a feat that’s presently past attain.

“There’s an enormous quantity of financial strain to enhance the infrastructure across the internet — whether or not that’s browsers themselves or the servers that host web sites or the databases,” Dahl mentioned. “[Our goal is to provide] very optimum, very low cost cloud companies.”

Former GitHub CEO Nat Friedman, a Deno investor, added in an announcement:

Deno is a brand new runtime for JavaScript that abstracts away all of the advanced capabilities of at the moment’s information facilities in native, easy-to-use JavaScript. This can revolutionize server programming by making it easier and extra intuitive to the biggest base of builders: JavaScript builders. Moreover, Deno’s structure as an isolate cloud helps the subsequent wave of internet improvement that depends closely on optimizations like … edge. This makes it a super platform for contemporary internet functions.

Apart from Sequoia, 4 Rivers Ventures, Rauch Capital, Lengthy Journey Ventures, the Mozilla Company and Shasta Ventures have backed Deno. The corporate at present has 17 workers and plans to rent 10 extra by subsequent 12 months.
