Kenton Varda's stated wager: an exclusive model "narrows our TAM," so Cloudflare bought the exit door and set a six-month clock on the rival host. ## Node.js's creator just sold the exit door Ryan Dahl built Deno to fix what Node.js got wrong [1][2]. In August his team shipped celld, [an open-source implementation of Cloudflare's Workers and Durable Objects](https://blog.cloudflare.com/deno-joins-cloudflare/) that scales across machines on hardware anyone controls [1][3]. [On October 9 Cloudflare bought the company; terms were not disclosed](https://thenewstack.io/cloudflare-acquires-deno-ryan-dahl/) [1]. The wind-down clocks started with the announcement [1][2]: Deno Deploy's paying customers get six months to migrate onto the acquirer's platform, and the runtime gets a year of monthly patches before development ends. For NET holders, the deal is a bet that portability widens the funnel into [Cloudflare](https://theinference.org/markets/companies/cloudflare)'s compute, not an admission that Workers needed a moat repair. ## $26 million in, no number out Deno raised about $26 million across two rounds: a $5.9 million seed in 2021 and [a $21 million Series A led by Sequoia Capital and announced on June 21, 2022](https://en.m.wikipedia.org/wiki/Deno_%28software%29) [1][2][4]. Terms of the sale were not disclosed [1], so the multiple on that money stays private. The market priced a neighboring layer the same day: Andreessen Horowitz led [an $870 million round valuing TypeSafe, whose Jev decision model contests Cloudflare's Clef line, at $7.5 billion](https://siliconangle.com/2026/10/09/jev-creator-typesafe-closes-870m-round-at-7-5b-valuation/) [5][6]. Sequoia, Deno's own Series A lead, was among the participants [5]. Deno's investors exited the runtime layer for an undisclosed sum [1]. ## The platform paid to remove its own trap Durable Objects are the internet's favorite Cloudflare lock-in accusation: apps built around them are hard to move, and celld was the unlock [3]. Cloudflare's answer was to buy it. "If the model is exclusive to us, that narrows our TAM," Cloudflare distinguished engineer Kenton Varda said; making the model work on every provider "comes back to benefit us" [1]. He conceded Cloudflare "just didn't have the right talent to see it through," and that workerd's Durable Objects have only ever run single-instance [1][2][3]. ## Same day, a 58% price cut The wager rides on a business still spending for growth: Q2 2026 revenue of $696.1 million, up 35.9% year over year, against a $205.7 million operating loss [7]. *Chart: **Cloudflare's quarterly revenue has more than doubled since Q3 2023** Line chart of Cloudflare quarterly revenue rising from $335.6 million in Q3 2023 to $696.1 million in Q2 2026* *Quarterly revenue in USD millions as reported in Cloudflare's SEC filings, Q3 2023 through Q2 2026. [7]* The same day, Cloudflare [cut Clef-flash's hosted input price from $0.09 to $0.038 per million tokens](https://runtimewire.com/article/cloudflare-clef-omni-multimodal-decision-model) [6], a price its rate card confirms [8]. The pattern across runtimes is consolidation: [Anthropic](https://theinference.org/markets/companies/anthropic) took Bun, the other Node.js alternative, in December 2025 [1]. Dahl's stated prize is agents, where Durable Objects bundle cheap execution, persistent state and WebSockets into one harness [1][9]. ## The exit door works, and the landlord owns it Varda's defense is on the record: [Shopify required an open-source runtime before it would build on Workers in 2022](https://www.technobezz.com/news/deno-joins-cloudflare-expand-workers-self-hosting), and former customers have used workerd to leave [3][10]. "We believe only the open version wins here," Dahl said [1]. The deadlines are on the calendar: Deno Deploy goes dark around April 2027, six months out, and runtime patches run monthly through October 2027 [1][2]. Cloudflare promises more on the merged celld-workerd runtime "in the coming months" [3]. Dahl indicated the combined project is expected to remain open source, likely under the Apache 2.0 license celld already uses [1]. For NET holders: an open Workers model [feeds Cloudflare's meter](https://theinference.org/article/cloudflare-s-bouncer-now-runs-the-bank-for-ai-agents) faster than a closed one defends it. ## Takeaway Cloudflare paid to make Workers portable: Deno's open celld runtime now feeds the same meter, with Deno Deploy dark around April 2027 and runtime patches ending a year later. ## Sources 1.
