blown away by how fast and consistent ships quality work.

The maker of just introduced v6. This update includes:

  • Composable rulesets

  • Compressed agent files

  • First-class support for more frameworks

  • Speed improvements

  • Biome 2.3.0 support

The project is open source. . OSS ftw!

hey , what are the main differences from your competitors?

TL,DR: is faster (Rust-based), AI-optimized, with a better DX. cc Β 

Β Primarily the fact that it's zero-config. You have a lot of choices for linters and formatters nowadays (Biome, ESLint, Oxlint, etc.) but they all take time to configure and maintain, which takes your focus away from application development.

Ultracite is designed to be the simplest and best approach: we picked the fastest linter and formatter, preconfigured it for you and made it play nice with others (editors, agents, integrations) so you can focus on your product and not the code quality.

Congrats on the launch πŸŽ‰

Congrats on the launch! πŸŽ‰ Seriously, this is the kind of tool devs have been waiting for. No setup, no config hell, just clean code that stays consistent. Gonna give Ultracite a spin right away.

enjoy :)
Looks great! Love the zero-config approach β€” that’s a huge time saver. Quick question: does it allow custom rules for team-specific styles?

congrats on the launch !!

Hi, it sounds amazing product, do you think it'd be non-tech expert friendly too? Would love to get advce from the creators! πŸ™Œ
