Bun is an all-in-one toolkit for JavaScript and TypeScript apps. It ships as a single executable called `bun`.
At its core is the _Bun runtime_, a fast JavaScript runtime designed as **a drop-in replacement for Node.js**. It's written in Rust and powered by JavaScriptCore under the hood, dramatically reducing startup times and memory usage.

“The default choice for production React today - server components, file-based routing, and first-class deployment story make it the fastest path from idea to shipped app.”
The Postgres development platform. Supabase gives you a dedicated Postgres database to build your web, mobile, and AI applications.
“A genuinely open-source Firebase alternative - real Postgres underneath, with auth, storage, and realtime built in rather than a proprietary database.”
“Utility-first CSS that's become the default styling approach for new projects - fast to write, easy to keep consistent, no dead CSS to prune later.”
Find vulnerabilities, misconfigurations, secrets, SBOM in containers, Kubernetes, code repositories, clouds and more
“A fast, all-in-one vulnerability scanner - containers, filesystems, git repos, and Terraform/IaC misconfigurations all covered by one CLI tool.”
“An all-in-one JavaScript runtime, bundler, test runner, and package manager - genuinely faster than the Node.js equivalents it replaces.”
“The de facto standard code editor - lightweight enough to feel instant, extensible enough to replace a full IDE for almost any language.”
“Makes monorepo builds fast via aggressive local/remote caching - the difference is dramatic once a repo has more than a couple of packages.”
“A content-addressable package manager that's both faster and dramatically more disk-efficient than npm/yarn, with none of npm's phantom-dependency bugs.”
“The modern default frontend build tool - native ESM in dev means a dev server that starts and reloads almost instantly, even on large apps.”
“The standard JavaScript linter - catches real bugs, not just style nits, and its plugin ecosystem covers virtually every framework.”
“The industry-standard container orchestrator - not always necessary at small scale, but the default assumption for any serious cloud-native platform team.”
“The most capable open-source relational database available - strong standards compliance, extensions for nearly everything (including full-text search and vectors), and a default choice for good reason.”
“Unifies dozens of LLM providers behind a single API, making model switching almost effortless in production.”
“The standard library for working with open-weight models - thousands of pretrained models are one line of code away.”
“The open-source engine behind Docker - understanding containers here pays off no matter which orchestrator sits on top later.”
“The most widely adopted framework for chaining LLM calls, tools, and retrieval into real applications - a near-default starting point for RAG and agent projects.”
