Bun vs Scalingo
A side-by-side editorial comparison of Bun and Scalingo — release velocity, themes, recent moves, and the top alternatives to consider.
Bun vs Scalingo: 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 Scalingo?
Scalingo opens its Application Firewall to every app and adds CLI commands for it.
Scalingo is a European PaaS that keeps runtimes close to upstream. On November 9 its Application Firewall became available for all applications, letting any app restrict public HTTP and HTTPS access to allowed IPv4 ranges, and CLI 1.52.0 added commands to list, add and remove those rules plus an organizations command. Earlier in the month it patched every stack image for a Brotli decoder CVE and rebuilt nginx against zlib 1.4.

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.
Scalingo
5.0DEVOPS
Scalingo opens its Application Firewall to every app and adds CLI commands for it.
◆ Current state
Scalingo is a European PaaS that keeps runtimes close to upstream. On November 9 its Application Firewall became available for all applications, letting any app restrict public HTTP and HTTPS access to allowed IPv4 ranges, and CLI 1.52.0 added commands to list, add and remove those rules plus an organizations command. Earlier in the month it patched every stack image for a Brotli decoder CVE and rebuilt nginx against zlib 1.4.
◆ Where it's heading
After October's router incident, the platform is adding security controls at the edge alongside its routine runtime updates. Firewall rules in the CLI suggest they are meant to be scripted, not just set in the dashboard.
◆ Prediction
Expect the firewall to gain more options, IPv6 ranges being the obvious gap, alongside the usual buildpack updates.
