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 Aiven?

Aiven moves Grafana to 13 and gives Runtime apps custom domains.

Aiven's November releases mix pricing changes with plumbing between its own services. The MySQL free tier stops on 21 December, bring-your-own-key encryption is included at no extra cost, and a change-data-capture integration now copies PostgreSQL tables into ClickHouse in limited availability. On 12 November Grafana 13.2 became available alongside 12.4, without Git Sync or the Synthetic Monitoring app, and Aiven Runtime applications gained custom domains and readable URLs.

Bun vs Aiven: editorial side-by-side

Bun
DEVOPS
6.3

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.

6.3

Aiven moves Grafana to 13 and gives Runtime apps custom domains.

◆ Current state

Aiven's November releases mix pricing changes with plumbing between its own services. The MySQL free tier stops on 21 December, bring-your-own-key encryption is included at no extra cost, and a change-data-capture integration now copies PostgreSQL tables into ClickHouse in limited availability. On 12 November Grafana 13.2 became available alongside 12.4, without Git Sync or the Synthetic Monitoring app, and Aiven Runtime applications gained custom domains and readable URLs.

◆ Where it's heading

Aiven is filling out the layer around its databases: logs, access control, encryption, dashboards and now an application runtime with its own domains. Each release is small, but together they make it easier to keep both data and the apps that use it on Aiven.

◆ Prediction

Expect more Aiven Runtime features that connect apps to Aiven's own databases, and a default-version switch to Grafana 13 once 12.4 nears end of support.
