Bun
A JavaScript runtime that starts faster, runs faster, and ships its own tooling.
What we build with it
- Fast APIs and lightweight services
- CLI tools
- Build tooling and scripts
- Services where cold-start time matters
Why we use it
Bun collapses runtime, package manager, bundler, and test runner into one fast tool. For new services without exotic dependencies it cuts both build times and server bills.
When we don't use it
Ecosystem certainty still belongs to Node. If a project depends on packages with native bindings or long-tail edge cases, we default to Node.
What we have written about Bun
- Bun in production: where it is ready and where it is not
A plain look at what Bun's runtime, installer, bundler, and test runner handle today, and the specific corners where Node still deserves the job.
- Go, Node, or Bun for your backend
A scenario-based look at Go, Node.js, and Bun for backend work, covering team fluency, concurrency, deployment shape, and ecosystem depth.
Questions clients ask
Short answers, no sales language. If yours isn't here, ask an engineer directly.
Ask us anythingIs Bun ready for production?
For plenty of workloads yes, and we run it where the dependency set is proven. Conservative projects still go on Node, and we are upfront about which side of that line yours falls on.
Should we migrate our Node service to Bun?
Only if it measurably pays. We benchmark your actual workload first, because a migration should be justified by numbers.
