Hire Bun.js developers

Bun differs from Node.js in several practical ways (package resolution, test-runner compatibility, bundling model, and some async/I/O edge cases), and engineers with Bun production experience avoid common friction and debugging surprises faster. Engineers who’ve worked through those differences in production ship faster and make fewer assumptions that cost you debugging time later.

Rates at Lemon.io run from $35–$90/hr, depending on seniority, the breadth of the stack (whether you need TypeScript, frontend, backend development, or all three), and hours per week. Most engagements are 20–40 hours per week.

For most web development and API work, yes. Bun has been in stable release since 1.0, and teams are running it in production. The honest caveat is that Node.js compatibility isn’t at 100%. Native addons and some niche npm packages still cause issues. A good Bun engineer knows where those edges are and how to handle them.

Both Deno and Bun offer native TypeScript-first runtimes. Deno emphasizes a stronger permission model and security posture, Bun emphasizes raw performance and an all‑in‑one toolkit with growing npm compatibility, and for a startup prioritizing speed and DX over sandboxing, Bun is often the more practical choice, while Deno suits strict-permission environments.

80% of matches close within 24 hours, and many finish in under 10. You submit your requirements, stack, hours per week, and domain. Lemon.io filters the vetted network, and you receive 1–3 candidates. If you need a replacement for any reason, that also comes within 24–48 hours.

Yes. That’s one of the most common situations. Bun is designed to be a drop-in replacement for Node.js in most cases, and many teams adopt it incrementally. Engineers from Lemon.io with Bun experience typically have strong Node.js backgrounds and know how to onboard new hires into a codebase mid-migration without breaking things.

Software development teams building high-volume APIs, real-time products, or serverless infrastructure get the clearest returns. That includes SaaS platforms, developer tools companies, fintech backends, and any startup where compute costs and build speed are active concerns. Bun also increasingly shows up in frontend build workflows for teams that want to cut toolchain dependencies without switching frameworks or rewriting use cases.

Look for engineers who know the full toolkit. A qualified Bun developer understands how JavaScriptCore handles async behavior differently from V8, has debugged real compatibility gaps with npm dependencies, and has used Bun’s bundler, package manager, and test runner in production. TypeScript fluency is crucial, too.

For products with real-time features, check the WebSocket experience specifically. Bun has a built-in server that removes the need for Socket.IO entirely. Experience with GitHub CI workflows, incremental migration, and frontend bundling for HTML and React projects can also be useful.
