A modern JavaScript runtime that combines a bundler, test runner, and package manager.

Business benefits

Why do we choose this solution?

Instant startup

Applications start many times faster than in traditional runtimes, which shortens developers' time and reduces latency.

Native TypeScript

TypeScript code runs without additional transpilation steps, simplifying project configuration and the pipeline.

All in one

A bundler, test runner, and package manager integrated into one tool reduce the number of dependencies.

Low resource usage

A lightweight engine lets you handle more traffic with less infrastructure, which genuinely lowers costs.

npm ecosystem compatibility

Seamless cooperation with existing npm packages makes migration and integration with popular libraries easy.

Faster CI/CD

Short install and build times translate into faster deployments and smoother iteration.

Our expertise

How do we work with Bun?

Bun is our choice wherever speed of operation and infrastructure lightness matter. In projects based on React Router and TypeScript, it lets us run the entire application without an additional transpilation layer.

Why do we choose Bun?

  • One toolchain: a bundler, tests, and package management in a single binary simplify onboarding and reduce configuration failures.
  • Lower bills: lower memory and CPU usage lets you serve more with the same infrastructure.
  • Predictability: deterministic and fast installs shorten build times in the CI/CD pipeline.

At Tesserakt we treat Bun as the foundation of efficient, modern applications — from prototype to production.
