I'm using Ultracite from @haydenbleasel. Is based on Biome. Is... Just *chef kiss*. ultracite.dev
Try ultracite, it’s based on biome ultracite.dev
I just updated the starter-kit with Ultracite ⚡️ github.com/rajatsandeepse…
maybe try biomejs, it's super fast. had a great experience so far. ultracite by @haydenbleasel is a solid option if you're going to try biome
✨ I'm unbelievably excited to introduce Ultracite v5: the AI-ready formatter that helps you write and generate code faster. 🙅 Zero-config ⚡ Lightning fast 🤖 Designed for humans and AI 💪 Maximum type safety 🔗 Plays nice with others Here's the TL;DR 👇🧵
This was an unbelievably easy setup. Just 2 commands - init & lint. Thank you for your OSS work!🫡 github.com/haydenbleasel/…

A few more lines later.. App is fully functional with Expo 53. Swapped for @biomejs and Ultracite. Didn't realize how much better a faster linter is for dev feedback loop.
So @shadcn is using ultracite which is basically a formatter so u gotta look at if ur running around with the quid pro quo tech stack

@amanvarshney01 it could be worth including this in better-t-stack if you're not already. seems like it would fit into your biome config stack pretty nicely.

Gosh this is sooo good! You cooked a big one @haydenbleasel!
this is so good! you can't tell me otherwise. @haydenbleasel cooked with this 👉 bunx ultracite@latest init
How could I overlook Ultracite until now? Just tested it and it’s incredible - huge props to @haydenbleasel Adding it to a bunch of projects rn
Now add ultracite.
One of the biggest lessons I learned from my first startup is to set the bar extremely high for code quality and linting from day one. If you do not, it turns into an impossible escalator you can never step off. We are big believers in ultracite.ai, and I am always
only the best stack 😍 @aisdk ❤️ ultracite 😍
ultracite.ai all the way
The fact that we need to tell AI that it needs to use semantic elements tells us the quality of software that is out there 😂 btw checkout ultracite.ai
It's been almost 2 weeks since I did this and I have to say Ultracite definitely is a lifesaver. Amazing work @haydenbleasel I want to ask tho is it good at other frameworks like say Astro or just even plain React or is it just Next.js?
Setting up Ultracite @haydenbleasel . Let's see how it goes
Every time I delay setting up "essentials" for a repo (e.g. ultracite.ai, alchemy.run
I specifically use ultracite.ai on top because I don’t want to think about configuration at all
ultracite is a gem. no more nutty eslint/prettier/editorconfig configuration and things are super easy to override or turn on/off as needed.
@haydenbleasel I just installed Ultracite on my project and this has been the best gift. I’m now effortlessly writing, clean code and fixing all my errors with these new rules in place. Thank you! 🙏
Ultraciteいいな、Biomeのルール考えるのも面倒だしもうこれ使っておけば良いなという気持ちです👌 ultracite.ai
Soon you’ll have instantaneous linting and formatting, it feels so good—also worth peeping github.com/haydenbleasel/…
How in the world did I just found out about ultracite.ai now, no one told me
Hey, just wanted to say how much I appreciate your work on Ultracite. I migrated all of my ts projects to it, and while it annoys the shit out of my agents, it's definitely helping them achieve a far better code quality. And @coderabbitai
Shout out to @haydenbleasel 👏 Sometimes all you need is formatting and linting — and ultracite.ai nails it. Minimal, fast, and beautifully opinionated. Try it once, and your codebase will never go back.
Zap.ts will support Biome over ESLint + Prettier w/ ultracite (@haydenbleasel) natively. github.com/alexandretrote…
とりあえずcodexのmcpに設定して使ってみる Vibe codingによって生成されたコードの品質を担保するためにUltraciteを使ってみた|シン zenn.dev/bita/articles/… #zenn
@haydenbleasel ultracite is one the best formatting tool I have ever used. Thanks man!
Ultraciteは、AIが生成したコードの品質担保のためのbiomeのプリセット。biomeはゼロコンフィグで機能するのが利点だけど、AIの爆走の制御には足りないので、厳格に制御するプリセットを提供している感じっぽい。関数の複雑さや行数上限のチェックも有効化されているようだ。 ultracite.ai
The ones from ultracite, by @haydenbleasel are awesome. Definitely expensive and more generic on purpose because it's the same for every project on init. Super great inspiration. I use it on every new project I make, together with better t stack from
@cursor_ai gpt-5-high is the best, no linter errors (ultracite by @haydenbleasel), understand my code style, understand my flow, work properly - in one prompt. Crazy good
OMG....i just discovered Ultracite! I must have been under a rock. Thanks @haydenbleasel
Yep 💯, Ultracite rocks, eslint+prettier sucks. @biomejs 💙💙🩵
if you don’t want to mess around with prettier & eslint configs and just want to ship fast, ultracite is your answer. out of the box, zero setup and your code is clean, consistent. ultracite.ai
@biomejs with ultracite, it's just perfect
@haydenbleasel is an absolute legend — his OSS stuff slaps! 🔥 Can’t get enough!🥰🥰 - next-forge.com - ultracite.ai - kibo-ui.com - ai-sdk.dev/elements/overv…
guys, ultracite is amazing! I use it in most of my projects! @haydenbleasel great work! 🔥
well deserved man! the recent stuff with ultracite by @haydenbleasel is really exciting 🙌
TIL no. 47: punting & formatting recently migrated from @PrettierCode and @geteslint to @biomejs
i've been moving more of my apps to biome, and i've really enjoyed it. but recently I moved an app to biome with ultracite.ai from @haydenbleasel
check out ultracite! ultracite.ai
might wanna look at ultracite ultracite.ai
enjoying ultracite, great work by @haydenbleasel
@haydenbleasel ultracite is sooo good!
Just added Ultracite to my project, and I’m seriously impressed. It’s making clean code feel effortless. The new rules are super helpful. They catch mistakes before I even notice them. Loving it so far! Big thanks to @haydenbleasel 🙌 ultracite.ai

HUGE 🙏🏻to @haydenbleasel for Ultracite Hey Genius, I wanna shout from the Rooftops about how Ultracite saved me today while migrating my Next15+ESLint project to Next16-beta+Biome I was struggling to debug It & I remembered Ultracite& installed it & BOOM🤯one-shotted all d bugs
Day 1 with ultracite Deleted 47 lines of ESLint config Removed 8 Prettier rules Fixed 342 lint errors automatically Setup time: 2 commands, 30 seconds My codebase has never looked this clean. Why did I wait so long? ultracite.ai
thanks for building Ultracite @haydenbleasel, it's awesome.
have you tried ultracite.ai
👀看看这个? github.com/haydenbleasel/…
Try ultracite by @haydenbleasel
Hice una app de concepto en menos de una hora que usa workers con el Claude Agent SDK para tomar tareas y resolverlas de forma agéntica - @remix_run - shadcn/ui @shadcn - PostgreSQL + @DrizzleORM - @better_auth (pass+Google) - @claudeai - Ultracite @haydenbleasel
shadcn/ui compiled Turbo repo setup with Bun. Comes with individual @biomejs setup through ultracite.ai. Result of my recent playing with @turborepo + @bunjavascript. Enjoyed Bun's new Catalog support. Organizing deps version is easier now 👉 github.com/mmikhan/next-w…
Try ultracite.ai as well
Muy contento con el stack de @lapyme_ar: - @nextjs: frontend + backend - @supabase
It is based on - tanstack start - svgo - intlayer - ultracite - shadcn ui - better t stack @tannerlinsley @tan_stack @haydenbleasel @shadcn @amanvarshney01
Ultracite by @haydenbleasel is something I can’t live without now. github.com/haydenbleasel/…
I was already stoked on this stack then added @haydenbleasel ultracite 6.3.2 and it’s just 👌
Migré @lapyme_ar a Ultracite después de leer haber leído buenas cosas por acá. Por ahora hice una migración parcial desde Eslint, pasando muchos de los errores a warning y resolviendo todos los errores nuevos con strictNullCheck. Fue un viaje, pero vale la pena en el largo plazo.
🧰 Ops & Growth 🔐 Auth: @better_auth 💳 Commerce: @polar_sh
Ultracite is awsome!! Can't go back to ESlint and Prettier ever again. Thanks @haydenbleasel 🐐
Here is my build anything tech stack for 2026: core: TypeScript, React, @nextjs, @vercel db: @neondatabase
The migration from SmoothUI to using Fumadocs, Nextjs 16, and Ultracite is almost complete! I'll probably publish it tomorrow. Thanks to @fuma_nama and @haydenbleasel
Ultracite feels magical. I set it up in seconds. Recommended. @haydenbleasel, amazing work.
sometimes all it takes to get motivated is a massive refactor huge thanks to @haydenbleasel for ultracite spent three days migrating many, many repos and yes I kept all the default rules
Choosing Ultracite was a blessing 😇 @haydenbleasel
Or just use @biomejs with ultracite 👍
replace prettier and eslint with @biomejs and ultracite.ai
If you're upgrading to Next.js 16 and using ESLint, you might run into some property errors. 🪓 That's because you need to migrate to the new ESLint Flat Config. You can either follow the migration guide in the docs, or take the easy route: Just create a new Next.js 16 app and
Using Ultracite by @haydenbleasel for ui.efferd.com — it’s seriously amazing.
