Just Fucking Use Ultracite
Stop wasting hours configuring your linting tools. Whether you use ESLint, Biome, or Oxlint—Ultracite gives you battle-tested presets so you can get back to actually building things.
Your linting setup is a disaster
Be honest with yourself. Your current setup probably looks like this:
- Config files with 200+ lines of rules you copied from Stack Overflow
- Formatter and linter rules that constantly conflict with each other
- Hours spent researching which rules to enable and which to ignore
- A
lint-stagedconfig that breaks every other commit - Rules that your AI assistant ignores because it has no idea they exist
And the worst part? Every new project means doing this shit all over again.
The Graveyard
Here lies everything you get to delete. May they rest in peace.
What the fuck is Ultracite?
Ultracite is a collection of zero-config presets for your favorite linting tools. Just pick your provider and be done with it.
Done. You now have hundreds of battle-tested linting rules, a formatter that doesn't fight your linter, and your AI assistant actually knows about your code style.
Smart people who stopped fucking around
These companies decided life's too short for config files.
Plus the Alan Turing Institute, the French Government, and the US Department of Veterans Affairs. Yes, really.
Why it's fucking great
Use whatever tools you want
Love ESLint's ecosystem? Use it. Want Biome's speed? Go for it. Excited about Oxlint? We got you. Ultracite doesn't care—it just gives you great defaults for all of them.
Your AI actually listens
Ultracite generates rule files for Cursor, Claude Code, Windsurf, GitHub Copilot, and more. So when you ask your AI to write code, it follows your rules instead of making up its own bullshit.
Hundreds of rules, zero research
We already figured out which rules matter. Type safety, accessibility, performance, security—it's all there. You don't need to read through 500 rule descriptions to build a good config.
Zero config, maximum opinions
Stop bikeshedding about tabs vs spaces or semicolons. Ultracite already decided for you. You're welcome.
Works with everything
Next.js, React, Vue, Svelte, Astro, Remix—it doesn't matter. Ultracite has framework-specific presets for all of them. Just pick yours and go.
What Ultracite decides for you
No more arguments. No more "let's discuss this in the next sprint." Here's what you're getting:
Don't like it? Too bad. (Just kidding, you can override anything. But you won't.)
Rules for everything you forgot to care about
Ultracite doesn't just format your code. It catches bugs, improves accessibility, and stops you from shipping garbage.
Your AI assistant is finally useful
Ever noticed how Copilot ignores your linting rules? That's because it doesn't know they exist. Ultracite generates rule files that your AI can actually read.
Now when you ask AI to write code, it writes code your way. Revolutionary, I know.
Pick your weapon
Can't decide which linter to use? Here's the honest breakdown:
| ESLint | Biome | Oxlint | |
|---|---|---|---|
| Speed | Slow | Fast as fuck | Fast as fuck |
| Ecosystem | Huge | Growing | New |
| Formatter | Prettier | Built-in | Oxfmt |
| Config UX | Pain | Nice | Nice |
| Maturity | Battle-tested | Production-ready | Getting there |
TL;DR: ESLint if you need specific plugins. Biome if you want speed and simplicity. Oxlint if you like living on the edge.
Already have a mess?
Migrating is easier than you think. Here's the plan:
- Delete your existing shit config
- Run
npx ultracite init - Run
npx ultracite fixto auto-fix everything - Commit the changes
- Never think about linting config again
That's it. The whole migration takes about 5 minutes. You've spent longer reading this page.
"But what about..."
"I have custom rules I need"
Cool. Override them. Ultracite is just a preset—you can add whatever rules you want on top. But you probably don't need to. The defaults are good.
"I already have a setup that works"
Does it though? When's the last time you updated those rules? Are your formatter and linter still fighting? Does your AI know about any of it? Ultracite keeps everything in sync and up-to-date.
"My team won't like the style choices"
Your team will like shipping code faster. Stop having meetings about formatting. Accept the defaults and move on with your lives.
Should you use Ultracite?
Just do it
You've been thinking about fixing your linting setup for months. Here's your sign. Run this and pick your preferred toolchain:
npx ultracite initThat's literally it. ESLint, Biome, Oxlint—whatever you pick, you'll get a bulletproof config in seconds. Stop overthinking. Stop researching. Stop comparing. Just fucking use Ultracite.
