Deno 2.9 lands: build native desktop apps from the web, no Electron

Deno shipped 2.9, headlined by deno desktop — a new way to package native desktop apps from the web stack you already know, with no Electron boilerplate and a single binary at the end. It turns a Deno project (from a single TypeScript file to a full Next.js app) into a self-contained binary that bundles the Deno runtime and a web rendering engine. Note: the feature currently requires the canary build and the API may still change before it stabilizes.

Key points

• deno desktop: build native desktop apps from Deno/Next.js, no Electron, one binary output.
• Easier migration: deno install reads npm, pnpm, yarn and Bun lockfiles directly — switching package managers is a couple of commands.
• CSS module imports: import CSS modules right in your code.
• Stronger testing: adds snapshot testing and parameterized testing.
• Smaller & faster: deno compile --bundle produces smaller binaries with faster startup.
• Node.js 26 compatibility.
