What is Biome?

Biome's patch train keeps adding rules — and is quietly growing a Markdown linter.

Six patch releases since mid-June, each mixing new nursery rules with parser and formatter fixes. 2.5.8 adds useReactCompiler, which surfaces React Compiler's own lint diagnostics through Biome, and makes HTML style attribute values parse as CSS so every CSS rule applies inside them. Framework coverage keeps deepening — Svelte legacy {@const} tags, Vue instance properties, Tailwind arbitrary values — and the JavaScript API package reached 6.0.0 with a byte-to-UTF-16 span helper.

What is PlanetScale?

PlanetScale is building out Postgres while making every control reachable without the dashboard.

The Postgres line carries the new capability: vectorscale extension support, storage configurable at database creation, out-of-memory alerts by both email and webhook, a customisable log line prefix, a Discovery Tool for evaluating existing databases, and updated pricing for private connection traffic. Database Traffic Control introduced resource budgets and has since gained warning thresholds and CLI management. The surface work is constant — API endpoints for backup policies, maintenance schedules, schema recommendations, deploy-request storage checks and invoice status, a Terraform provider at v1, and an Insights-only MCP server.

Biome vs PlanetScale: editorial side-by-side

Biome
INFRA · APIS
5.0

Biome's patch train keeps adding rules — and is quietly growing a Markdown linter.

◆ Current state

Six patch releases since mid-June, each mixing new nursery rules with parser and formatter fixes. 2.5.8 adds useReactCompiler, which surfaces React Compiler's own lint diagnostics through Biome, and makes HTML style attribute values parse as CSS so every CSS rule applies inside them. Framework coverage keeps deepening — Svelte legacy {@const} tags, Vue instance properties, Tailwind arbitrary values — and the JavaScript API package reached 6.0.0 with a byte-to-UTF-16 span helper.

◆ Where it's heading

The rule set is widening along two axes at once: frameworks and file types. Framework rules are now specific enough to argue about Svelte runes rather than generic JavaScript, and CSS handling has pushed into HTML attributes and registered custom properties. The larger move sits in 2.5.8's PR list rather than its changelog — a markdown linter, a markdown rule generator, a markdownlint rule source, a two-phase markdown parser, and a first rule in useTopLevelHeading, none of it documented for users yet.

◆ Prediction

Markdown linting looks close enough to ready that it should appear in the changelog proper rather than the PR list, most likely as nursery rules in the next minor.

PlanetScale is building out Postgres while making every control reachable without the dashboard.

◆ Current state

The Postgres line carries the new capability: vectorscale extension support, storage configurable at database creation, out-of-memory alerts by both email and webhook, a customisable log line prefix, a Discovery Tool for evaluating existing databases, and updated pricing for private connection traffic. Database Traffic Control introduced resource budgets and has since gained warning thresholds and CLI management. The surface work is constant — API endpoints for backup policies, maintenance schedules, schema recommendations, deploy-request storage checks and invoice status, a Terraform provider at v1, and an Insights-only MCP server.

◆ Where it's heading

PlanetScale is doing two things at once: closing the gap between its Postgres offering and its MySQL heritage, and making every operation scriptable. The API, Terraform and MCP work share a single goal — nothing should require the dashboard — and the schema-recommendations feature landing simultaneously as a REST endpoint and an MCP tool is the clearest statement of it. Traffic Control is the exception, launched as a named product surface and then immediately given the same CLI and threshold treatment.

◆ Prediction

Expect the remaining Postgres parity items and more MCP tools mirroring existing REST endpoints, following the schema-recommendations pattern where both arrived together.
