Bun vs Grav
A side-by-side editorial comparison of Bun and Grav — release velocity, themes, recent moves, and the top alternatives to consider.
Bun vs Grav: 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 Grav?
Grav backports a Clockwork profiler security fix from 2.1.7 to its 1.7 line.
Grav's only entry in the feed is 1.7.53.6, a patch to the legacy 1.7 branch. It backports a Grav 2.1.7 security fix so Clockwork profiler data requires a configured debugger.token, even for requests arriving from localhost through a same-server reverse proxy. It also keeps accented letters intact in title-derived slugs on PHP 7.3 to 8.1 with single-byte locales.

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.
Grav
2.5DEVOPS
Grav backports a Clockwork profiler security fix from 2.1.7 to its 1.7 line.
◆ Current state
Grav's only entry in the feed is 1.7.53.6, a patch to the legacy 1.7 branch. It backports a Grav 2.1.7 security fix so Clockwork profiler data requires a configured debugger.token, even for requests arriving from localhost through a same-server reverse proxy. It also keeps accented letters intact in title-derived slugs on PHP 7.3 to 8.1 with single-byte locales.
◆ Where it's heading
The fix originates on Grav 2.x and is carried back to 1.7, so the project is maintaining two lines, with 1.7 receiving security and compatibility patches for older PHP versions. With a single entry, the cadence on either branch isn't visible yet.
◆ Prediction
Expect further 1.7.53.x patches that mirror security fixes from the 2.x line. The entries don't show how long 1.7 support continues.
