Here's what some of the most in the most forward-thinking developers in the React ecosystem have to say about Ultracite.
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
Yeah ultracite has a few nice configs that I am also integatring into supastarter :)
✨ 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/…

Impressive, great job! I tested it right now, and it works perfectly. Even auto-sorting imports is included by default. I can't believe I overlooked Ultracite until now.
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.
legit was just looking to integrate ultracite and biome in my monorepo to replace eslint/prettier. hyped for this and congrats on the ship!
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

started using this for all my projects. I have now escaped the eslint hell of errors
Result after formatting. Clean and sorted imports 👌
Ultracite autocorrected on my iPhone to “ultra cute” and I think that’s a good sign
looks great!
really cool!
That’s really cool! I’d love support for left-hook as well. I also love to set up commitlint, so that would be awesome if it were included.
@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.

love it, creative AI linter/formatter
It looks really great! You've got the designer eye man.
Installing it right away!
Gosh this is sooo good! You cooked a big one @haydenbleasel!
Looks great 👍
this is so good! you can't tell me otherwise. @haydenbleasel cooked with this 👉 bunx ultracite@latest init
ultracite is goated
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 😍
I just install ultracite and tell the AI to do what it says. So kebab-case it is
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
Yup, biome is great check Ultracite as well
ultracite rocks especially when the man himself adds it
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.
Have you tried ultracite for for managing formatting and linting? I've been liking it a lot so far. Helps keep agents really consistent with code style
Ultracite is the future!
the hollow knight silksong version of this is when you remove eslint and install biome+ultracite and see issues you never knew existed
@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 makes it 100 times more enjoyable
totally agree ultracite is a lifesaver for config
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/…
Starting with high standards creates a culture that compounds over time. It is easier to scale when quality is embedded from day one rather than patched later. The interesting part is how tools like ultracite can make that discipline more accessible to every team.
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
Highly recommend moving over to Ultracite, super easy to setup and much faster. Been using it for months and love it.
cuz devs are lazy and stupid and don't actually read. most IDE/tools support at least one or two general places. For example, I've seen a tool putting rules for one thing in .rules FILE! while Zed supports that to be a fricking directory! ultracite, convex and bun all do this!
Solid update, guys! Been using Ultracite for my latest project and this is exactly the kind of thing I was hoping you'd do next
@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…
Started a new project using ultracite and never want to go back to eslint+prettier.
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 🙌
amazing 🥳 adding ultracite was always the first thing after initialization
Ultracite has taught to both love type safe codebase and at the same time despise linting possibly more uniting testing. Awesome updates though, not a bad ship for a Monday!
TIL no. 47: punting & formatting recently migrated from @PrettierCode and @geteslint to @biomejs
TIL no. 46: lovable scoping as i’m working on @withduckyAI, one thing i’m think about most is what’s the simplest but best way to build out the ui, workflow, data management, and experience. based on previous experience, there’s only one way: build -> talk to users ->
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
I got biome set up on my monorepo last night, after quite the humbling 😅 But I want all the benefits of Ultracite for cursor. Will try this weekend if I get chance 🫡
check out ultracite! ultracite.ai
clean and fast tools are what every dev needs. ultracite looks solid for modern projects. checking it out.
Plan mode + ultracite is the banger 🔥
might wanna look at ultracite ultracite.ai
Use ultracite with biome 👌🏾
Antes usaba Tinder, ahora uso Ultracite
Setting up ultracite was so much easier than using eslint + prettier. Great work
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.
I was using only Biome until some days ago but now Ultracite from now on... really great!
Ultracite really made things easier
love ultracite. first used it a couple months back. yet to set it up for my current project (just running biome).
have you tried ultracite.ai
Try ultracite by @haydenbleasel
Yup, having the llms run `bun ultracite check/fix` has really improved the amount of hand editing of final code
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
i really recommend ultracite if you use Claude or any other coding agent. super usefull, it also uses biome
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 or bust
Ultracite by @haydenbleasel is something I can’t live without now. github.com/haydenbleasel/…
only missing ultracite and unlimited shipping unlocked
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.
hmmm got some examples ? im not getting it entierly.. sorry.. typecheck finds type issues, lint finds linting issues, what does it have to do with types.. i have fully onboarded myself to ultracite(biome)+bun+typecheck soooo i feel the oppurunity cost of trying new tools
🧰 Ops & Growth 🔐 Auth: @better_auth 💳 Commerce: @polar_sh
ultracite is the ultimate biome config.
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
New video drop 🪓 WITH THIS TECH STACK YOU CAN BUILD ANYTHING! ⚔️ I'm revealing the ultimate 2026 tech stack, the exact tools I use to build anything: frontend, backend, AI, auth, emails, payments… all of it. Link below 👇
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
I just recently started using ultracite, coming from eslint. It's so good, thanks.
Yes and it's very powerful Specifically in linting. Try ultracite
I love ultracite, truly set and forget. Thanks for continuing the development!
Ultracite feels magical. I set it up in seconds. Recommended. @haydenbleasel, amazing work.
I played around with Vite ecosystem and it’s pretty good too (oxlint + prettier oxc plugin for now, oxfmt coming soon). Ultracite rules are great and I agree with most of them.
this is how my biome config looks without ultracite 😭
awesome, time to update my projects to ultracite thanks!
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
Huge fan of hardcore opinionated setup just like Ultracite is. I use it everywhere in my projects.
Choosing Ultracite was a blessing 😇 @haydenbleasel
Or just use @biomejs with ultracite 👍
加个 lint 啊，我用的 ultracite 提交前自动修复
ESLint is cooked. I use Biome with Ultracite and it works without any issues. Awesome upgrade from ESLint. But yeah...some people/companies can't migrate yet.
replace prettier and eslint with @biomejs and ultracite.ai
ultracite is biome at its best you’ve gotta try it
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.
