Is Bun compatible with Node.js packages?

Yes. Bun implements most Node.js APIs and is compatible with the vast majority of npm packages. It can serve as a drop-in replacement for Node.js in most projects.

Why is Bun faster than Node.js?

Bun uses JavaScriptCore (Safari engine) instead of V8, is written in Zig for low-level performance, and implements native APIs for HTTP, WebSockets, and file I/O that bypass the overhead of Node.js abstractions.

Is Bun stable enough for production?

Bun has reached stable 1.x releases and is used in production by many companies. For mission-critical applications, we run comprehensive compatibility testing against your specific dependency tree.

Bun Development for Maximum Speed

Our AI-managed teams build applications with Bun, the fastest JavaScript runtime, delivering superior throughput and developer experience.

Technology: Bun (JavaScript Runtime)

Bun is an all-in-one JavaScript runtime, bundler, transpiler, and package manager built from scratch for speed. Using JavaScriptCore instead of V8 and implemented in Zig, Bun offers dramatically faster startup times, package installation, and bundling. Our teams use Bun to accelerate development workflows and build high-throughput server applications.

What We Build

High-Throughput API Servers: API servers that handle 3-4x more requests per second than equivalent Node.js implementations with lower latency.
Build Tooling and Dev Servers: Blazing-fast development environments with instant hot module replacement, native TypeScript execution, and sub-second builds.
Monorepo Package Management: Monorepo setups with Bun workspaces that install dependencies in seconds instead of minutes compared to npm or yarn.
Full-Stack Applications: Complete web applications using Bun native APIs for HTTP serving, file I/O, and SQLite with minimal dependency footprint.
