Bun, the fast all-in-one JavaScript runtime: releases, production use and how it compares to Node and Deno.
A production deep dive into Bun v1.3.11 — covering Bun.cron for OS-level scheduling, Bun.sliceAnsi for terminal-aware string slicing, enriched Markdown rendering callbacks, path-ignore patterns for test discovery, and the dgram UDP fixes that unblocked real-world libraries on macOS.
Past the benchmark charts and feature matrices — here's what Deno's permission system and Bun's native APIs look like when you build something real with them. The gotchas, the sharp edges, and the parts that are actually better than Node.
Three JavaScript runtimes. Three different philosophies on what the developer experience should feel like. Here's how they compare on performance, ecosystem, tooling, and the only decision that actually matters for production.
Bun is a JavaScript runtime, package manager, bundler, and test runner in a single binary written in Zig. It's also the fastest thing to happen to JavaScript tooling in years — and it runs your existing Node.js code.
