Deno Desktop in Deno 2.9 compiles TypeScript projects into native apps with a system WebView or bundled Chromium. How it compares to Electron and Tauri.

All-in-one JavaScript runtime, bundler, test runner, and package manager. Rewritten in Rust as of Bun 1.4 (August 2026), drop-in compatible with Node, dramatically faster install and start times.

The original server-side JavaScript runtime. V8 under the hood, npm ecosystem, and the default backend runtime for most production deployments.

Secure-by-default JavaScript and TypeScript runtime from Node's original creator, with built-in TypeScript, fmt, lint, and test. The Deno team joined Cloudflare in October 2026: the runtime gets one more year of bug-fix and security releases, and Deno Deploy shuts down six months after the announcement.

The standard JavaScript and TypeScript linter. Massive plugin ecosystem, framework-specific configs, and integration with every editor.

Vercel's high-performance monorepo build system. Remote caching, task pipelines, and incremental builds. Drop into any pnpm or npm workspace.

Fast, disk-efficient package manager. Content-addressable global store, strict dependency resolution, first-class workspaces. Default for many TypeScript monorepos.

The default JavaScript package manager. Ships with Node, hosts the largest software registry in the world, and remains the safest compatibility default.

The long-standing JavaScript test framework, now stewarded by the OpenJS Foundation. Snapshots, mocks, parallelism, and the broadest plugin ecosystem in the JS testing world.
