Bun vs Z-Wave JS
A side-by-side editorial comparison of Bun and Z-Wave JS — release velocity, themes, recent moves, and the top alternatives to consider.
Bun vs Z-Wave JS: 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 Z-Wave JS?
Z-Wave JS v15.31.2 puts endpoint grouping to work across a batch of meters and shutters.
v15.31.2 is a patch with four driver fixes: invalid Powerlevel statuses rejected, nvmedit ignoring stale bytes, migrated 700/800 controllers set to Static Controller, and application presets no longer overwritten. It also adds ten device config changes, eight of them using the v15.31.0 endpoint grouping feature for Zipato, Qubino, Aeotec, Shelly and Intermatic devices.

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.
Z-Wave JS
5.0DEVOPS
Z-Wave JS v15.31.2 puts endpoint grouping to work across a batch of meters and shutters.
◆ Current state
v15.31.2 is a patch with four driver fixes: invalid Powerlevel statuses rejected, nvmedit ignoring stale bytes, migrated 700/800 controllers set to Static Controller, and application presets no longer overwritten. It also adds ten device config changes, eight of them using the v15.31.0 endpoint grouping feature for Zipato, Qubino, Aeotec, Shelly and Intermatic devices.
◆ Where it's heading
The project is in a steady cycle: a feature minor about every two to four weeks, followed by patches that apply the new feature through device configs. The RCP firmware driver from v15.28 and command deduplication from v15.29 were the last big capability moves. Since then, work has gone into config coverage and controller-migration correctness.
◆ Prediction
Expect v15.32.0 in the next few weeks, with more device configs moving to endpoint grouping in the patches that follow it.
