Biome vs Supabase
A side-by-side editorial comparison of Biome and Supabase — release velocity, themes, recent moves, and the top alternatives to consider.
Biome vs Supabase: at a glance
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 Supabase?
Supabase is closing its most-exploited default: tables stop being public unless you say so.
The last month is dominated by tightening defaults rather than adding surface. New tables in the public schema will no longer be auto-exposed to the Data and GraphQL APIs, pg_graphql stops being enabled by default, and the OAuth token endpoint is being corrected to return 200 per OAuth 2.1. Alongside that, custom OAuth/OIDC providers landed for Auth and an RLS Tester entered preview.

Biome

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.
Supabase

Supabase is closing its most-exploited default: tables stop being public unless you say so.
◆ Current state
The last month is dominated by tightening defaults rather than adding surface. New tables in the public schema will no longer be auto-exposed to the Data and GraphQL APIs, pg_graphql stops being enabled by default, and the OAuth token endpoint is being corrected to return 200 per OAuth 2.1. Alongside that, custom OAuth/OIDC providers landed for Auth and an RLS Tester entered preview.
◆ Where it's heading
Supabase is paying down the security cost of its own convenience. Auto-exposing every public-schema table made the product fast to start with and easy to misconfigure; the fix is explicit Postgres grants, staged over six months from new projects in April to all existing projects on October 30. The RLS Tester is the same theme from the other side — the auto-exposure default only worked if row-level security was correct, and until now there was no way to check.
◆ Prediction
Expect the remaining rollout dates to hold and more of the developer experience to be rebuilt around explicit grants, with the RLS Tester graduating from preview as it becomes the tool people need to verify the new model. The October cutover for existing projects is the moment where this stops being an announcement and starts breaking things.
