Bun vs Zed: at a glance
What is Bun?
Bun 1.4.4 adds bun fmt, a built-in Prettier-compatible formatter, two weeks after bun check.
Bun now covers formatting as well as type checking: v1.4.4 ships bun fmt, a Prettier-compatible formatter it says is 3-6x faster than oxfmt, and makes bun check 1.4-7.8x faster on large projects. The same release closes 271 issues, migrates Yarn Berry lockfiles, adds install retries with backoff, and cuts Bun.SQL CPU per query by up to 48%.
What is Zed?
Zed 1.27 writes commit messages in your repo's style and trims agent memory use.
Zed ships a weekly minor plus patches. 1.27.0 adds Go 1.27 generic-method highlighting, an option to open README files in new windows, AI commit messages that copy the style of the repository's last three commits, and lazy loading that cuts Agent Panel memory and CPU on long threads. 1.26 added Pyrefly for Python and WebAssembly stepping in the JavaScript debugger.

Bun
6.3DEVOPS
Bun 1.4.4 adds bun fmt, a built-in Prettier-compatible formatter, two weeks after bun check.
◆ Current state
Bun now covers formatting as well as type checking: v1.4.4 ships bun fmt, a Prettier-compatible formatter it says is 3-6x faster than oxfmt, and makes bun check 1.4-7.8x faster on large projects. The same release closes 271 issues, migrates Yarn Berry lockfiles, adds install retries with backoff, and cuts Bun.SQL CPU per query by up to 48%.
◆ Where it's heading
After the Rust rewrite in July and bun check in v1.4.3, Bun is absorbing the remaining steps of a TypeScript toolchain one release at a time. Package-manager reliability work (Yarn Berry migration, retries, faster hoisted installs) shows it is also going after teams still on other package managers.
◆ Prediction
Expect a linter or lint mode next to round out the check/fmt pair, and more lockfile migrations aimed at pnpm and Yarn users.
Zed
5.0DEVOPS
Zed 1.27 writes commit messages in your repo's style and trims agent memory use.
◆ Current state
Zed ships a weekly minor plus patches. 1.27.0 adds Go 1.27 generic-method highlighting, an option to open README files in new windows, AI commit messages that copy the style of the repository's last three commits, and lazy loading that cuts Agent Panel memory and CPU on long threads. 1.26 added Pyrefly for Python and WebAssembly stepping in the JavaScript debugger.
◆ Where it's heading
The agent side is now in a tuning phase: recent releases spend more effort on resource use, defaults and small quality gains than on new agent capabilities. Core editor work (languages, debugger, Git Graph) keeps pace alongside it.
◆ Prediction
Expect more agent performance and quality-of-life fixes plus another round of language and Git Graph additions in 1.28.
