Cloudflare Workers
Which Should You Choose?
Choose Bun if:
- •You want a fast, all-in-one JavaScript runtime that replaces Node.js, npm, and webpack in a single binary
- •Your project needs a local development runtime with built-in bundler, test runner, and package manager
- •You prefer open-source tools with zero vendor lock-in — Bun is MIT-licensed and free forever
- •Performance is critical — Bun's native code execution is significantly faster than Node.js for startup time and I/O
Choose Cloudflare Workers if:
- •You need a serverless edge computing platform that deploys code to 300+ locations worldwide
- •Your application requires near-zero cold starts at the edge with automatic scaling
- •You want an integrated ecosystem with KV storage, R2 object storage, D1 databases, and Queues
- •You need to run code as close to your users as possible for latency-sensitive applications
Bun and Cloudflare Workers occupy different layers of the JavaScript stack. Bun is an open-source JavaScript runtime — a faster alternative to Node.js that you install locally and run anywhere. Cloudflare Workers is a serverless edge compute platform where you deploy code to Cloudflare's global network. Comparing them is like comparing an engine to a car: one is a component, the other is a complete deployment solution. Bun is entirely free and open-source (MIT license). You download the binary, run your JavaScript or TypeScript, and pay nothing. It includes a bundler, test runner, and package manager — replacing Node.js, webpack, and npm in one tool. There are no tiers, no usage limits, and no vendor lock-in. Cloudflare Workers Free gives you 100,000 requests/day with 10ms CPU time per invocation. The Paid plan at $5/month includes 10 million requests/month, 30ms CPU time, and access to KV, R2, and D1 storage services. For high-traffic applications, the Enterprise tier offers custom pricing with higher limits, SLAs, and dedicated support. These tools are complementary rather than competitive. Many developers use Bun as their local runtime and development tool, then deploy to Cloudflare Workers for production edge hosting. If you are choosing a runtime for a backend service you will self-host, Bun is a compelling Node.js replacement. If you need managed serverless deployment with global edge distribution, Cloudflare Workers handles the infrastructure so you do not have to. The $5/month Workers plan is remarkably generous for most projects, while Bun costs nothing at all.
