This page is designed to help you find out whether Bun.sh is good and if it is the right choice for you.
Bun is a new JavaScript runtime built from scratch to serve the modern JavaScript ecosystem. It has three major design goals:
Speed. Bun starts fast and runs fast. It extends JavaScriptCore, the performance-minded JS engine built for Safari. As computing moves to the edge, this is critical.
Elegant APIs. Bun provides a minimal set of highly-optimimized APIs for performing common tasks, like starting an HTTP server and writing files.
Cohesive DX. Bun is a complete toolkit for building JavaScript apps, including a package manager, test runner, and bundler.
Bun is designed as a drop-in replacement for Node.js. It natively implements hundreds of Node.js and Web APIs, including fs, path, Buffer and more.
The goal of Bun is to run most of the world's server-side JavaScript and provide tools to improve performance, reduce complexity, and multiply developer productivity.

Speed
Bun.sh is designed for performance and is optimized for running JavaScript and TypeScript quickly. This can lead to faster development cycles and more efficient runtime performance.
Built-in Tools
Bun.sh comes with a built-in bundler, transpiler, and package manager. This reduces the need for additional tooling and simplifies the development setup.
TypeScript Support
Bun.sh has native support for TypeScript, making it easier for developers who prefer strongly typed languages to work seamlessly without additional configuration.
Compatibility
Bun aims to be compatible with existing npm packages, reducing friction in adopting it for existing projects.
Lower Resource Usage
Bun is designed to use fewer resources compared to some traditional Node.js setups, which could lead to cost savings in a production environment.

Bun.sh is considered a good option, especially for developers seeking high-performance solutions and a streamlined tooling experience. Its focus on speed and integration can make it an attractive choice for certain projects.
We have collected here some useful links to help you find out if Bun.sh is good.
Check the traffic stats of Bun.sh on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Bun.sh on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Bun.sh's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Bun.sh on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

The tools that do need a server run on Bun. Each one is there because of one of the four reasons above, and I can tell you which:. - Source: dev.to / 2 days ago
Built with Next.js 16 (React 19), Bun, Tailwind CSS v4, and shadcn/ui on Base UI — scaffolded with create-notils and linted with Biome. - Source: dev.to / 2 days ago
Direct API probing — calling the actual method on the actual installed Bun binary (1.4.0) and recording what happens, success or exception, before writing a single line of pipeline code around it. - Source: dev.to / 6 days ago
It runs on Bun and needs no global install, since bunx fetches and runs it in one step. The first run downloads Chromium once. Every run after that is instant. - Source: dev.to / 18 days ago
This directory contains the TypeScript implementation of the CLI. End users Should install the precompiled backboard binary. Contributors can run or Compile it from source with Bun. - Source: dev.to / 22 days ago
The Node.js ecosystem has powered bots for a decade via discord.js. However, the Bun runtime has completely changed the game. Bun acts as an all-in-one JavaScript toolkit that starts up significantly faster and utilizes memory far more efficiently than standard Node.js. - Source: dev.to / 2 months ago
The binary had a #!/usr/bin/env bun shebang and imported bun:sqlite. I had developed the whole thing under Bun, so on my machine it was perfect. On a normal machine with only Node installed, there is no bun to run the shebang, the entry was a .ts file Node would not execute, and even if it got that far, bun:sqlite is a built-in that only exists inside Bun. Three separate ways to fail before any of my code ran.... - Source: dev.to / 3 months ago
The CLI is a thin Bun wrapper; the engine is the Rust binary it shells out to. Pipe-friendly by design — transcript on stdout, errors on stderr. - Source: dev.to / 3 months ago
The numbers are striking. According to benchmarks published on bun.sh, Bun handles 59,026 Express.js "hello world" HTTP requests per second on Linux x64, compared to 25,335 for Deno and 19,039 for Node.js. For WebSocket throughput, Bun clocks 2,536,227 messages per second against Deno's 1,320,525 and Node's 435,099. Bun also bundles 10,000 React components in 269ms. Rolldown completes the same job in 495ms.... - Source: dev.to / 4 months ago
Toolchains: I use SDKMAN! For JDKs, NVM for Node.js, rustup for Rust, Bun, Go, Python, Deno, and the usual Linux build tools. - Source: dev.to / 4 months ago
For the curious: gitui is built with Bun, React 19, and OpenTUI — a relatively new library for making terminal UIs feel like real apps. Every GitHub call is just a shell-out to gh, which means there's no token plumbing and no API client to maintain. If gh pr list works in your terminal, gitui works. - Source: dev.to / 4 months ago
The official plugin runs on Bun -- a JavaScript runtime. It works, but it's heavy: ~100 MB RAM per instance, 2-3 second startup, and it doesn't clean up after itself. - Source: dev.to / 5 months ago
The UI layer is built with React and Ink, a library that renders React components to the terminal. Layout is handled by Yoga, the Flexbox engine that also powers React Native. The runtime is Bun rather than Node.js, and the entire application compiles down to a single cli.js bundle at 10.5MB. - Source: dev.to / 5 months ago
Prerequisites: Bun and a Telegram bot token from @BotFather. - Source: dev.to / 5 months ago
Bun includes a built-in HTTP server that's 5-10x faster than Node.js + Express. No npm install needed — just Bun.serve() and you have a production-ready server. - Source: dev.to / 5 months ago

While having everything in one tool helps, it does have some DX papercuts at this point. For example, while they do support most package managers (pnpm, npm, yarn), they are missing bun. There is also some more work to be done with the vite.config.ts on Nuxt and TanStack Start since the tooling for each aren't quite there yet. Nevertheless it's early days in Vite+, and it's still in alpha, so I'm sure the updates... - Source: dev.to / 6 months ago
To get started: install Bun, then run bun install to install dependencies (We have two: @apidevtools/swagger-parser, and turndown). - Source: dev.to / 6 months ago
For what it's worth, Bun is written in Zig (https://bun.sh/). The language isn't exactly in an early stage. - Source: Hacker News / 7 months ago
There are also no-framework approaches. These rely directly on React-provided packages and low-level integrations with bundlers like Webpack or experimental support in tools like Bun. While technically possible, these setups are fragile. React explicitly does not guarantee stability of these internal APIs. Any team choosing this route must accept ongoing maintenance risk. - Source: dev.to / 7 months ago
