Which JavaScript runtime wins in 2026:
- Node.js is still the safe default for production work that needs maximum ecosystem compatibility.
- Bun has the fastest startup, installs, and test runner, and is the best fit for new projects that prioritize developer experience.
- Deno is the most secure by default and the best TypeScript-first experience. Since the 2.9 release, it’s also the fastest at raw HTTP throughput on my test bench.
All three are production-ready in 2026, so the decision should come down to your constraints rather than benchmark headlines.
