CatDoes v4 - An AI agent with its own computer builds your apps
byβ’
CatDoes is a no-code app builder. Its AI agent, Compose, runs in the cloud and has its own computer, so you can close the tab and it keeps working. Compose writes the code, installs the packages, runs the tests, and fixes its own errors. It builds mobile apps and websites. Every plan comes with a backend included, database and auth and storage and edge functions and real-time events. For founders, SMBs, designers, and engineers who want to move faster.

π Hey Product Hunt,
I'm Mahdi, co-founder of CatDoes. Building this with Nafis. Big thanks to @thisiskp_ for hunting us today.
This is our third time here. v3 was "a team of AI agents that builds your mobile app." v4 is where that idea grew up.
The core of v4 is Compose, our new AI agent. It replaces the old specialist-team setup with a single autonomous agent that works more like an engineer you can hand things off to than a copilot that sits next to you while you code.
A few things that are actually different about Compose:
- It runs in the cloud. You describe what you want, close the tab, go to sleep, come back. Compose has been working the whole time.
- It has its own computer. So it can install packages, run scripts, try a build, read the output, and try again if something fails. It doesn't suggest code changes, it writes them, runs them, and fixes them when they break.
- It spawns subagents. If your request has three independent parts, Compose runs them in parallel instead of serially.
- It decides what to do next. Plans the work, writes the code, runs the tests, ships the build, reads the errors, fixes them.
What Compose builds
Mobile apps and websites. You can start from scratch or import a GitHub repo. Paste a URL (Lovable, WordPress, Shopify, whatever) and Compose will turn that website into a mobile app. Fork any of your projects to ship the same product under a different brand. It also monitors your app's errors via CatDoes Watch (Built-in error monitoring) and will fix them when you ask.
Every plan ships with a full backend: CatDoes Cloud. Database, auth, storage, real-time, edge functions. US and EU regions. No separate setup, no extra vendor.
What's new since v3
- Compose Agent: autonomous, cloud-native, has its own computer
- CatDoes Cloud: backend included on every plan
- Websites + custom domains
- Import from GitHub
- Monorepos with a preview size switcher (mobile, desktop, iPad, phone sizes)
- Website to Mobile App convertor
- File Browser (edit your code from the dashboard)
- Multi-page Canvas (see every screen at once)
- CatDoes Watch (built-in error monitoring, dev and prod)
- Env Manager (store secrets the AI can request but never read)
- Fork Projects
- Principal Agent tier, our smartest agent yet
Who it's for
- Founders going from idea to a real app in days
- Designers whose prototypes should actually run
- Small businesses that finally need a mobile and web presence
- Engineers who want to ship 10x faster
- Anyone who's been waiting for tech to catch up with their idea
Product Hunt perks
- 20% off your first paid month with code V4_PH_20, valid this week
- Drop your idea in the comments and I'll reply with how Compose would tackle it. If it's interesting, we'll spin it up and share what Compose built.
Thanks for taking a look. Feedback from people who showed up for v2 and v3 is a big reason this version exists. π

Batteries-included by default, and exits are there when you want them. CatDoes Cloud (db, auth, storage, realtime, edge functions) ships on every plan and most builders want to ship, not shop for infra. Under the hood we use open-source tech, nothing proprietary. Code export is there whenever you want to own the code and leave, and because the stack is open-source the exported code actually runs elsewhere.
GitHub import works the other way where you can bring any repo in and the agent will work on it. The agent isn't locked to Cloud either; it can wire up Stripe, Clerk, your own Postgres, whatever, by writing against it.
Cloud's EU region is live at data centers in Europe for data residency, and teams and enterprises can run private Cloud deployments.
On secrets and safety: our Env Manager encrypts everything, the agent only ever sees which keys exist, never the values. For sensitive inputs, there's a secure input field where values are encrypted on entry and the agent just knows a value is provided and proceeds. Each project runs on its own isolated cloud machine, so no cross-contamination between builds.
Also, CatDoes Watch monitors prod and hands errors back to the agent when you want them fixed.

Hey PH fam π
Super excited to hunt CatDoes v4 today β and this one is a meaningful step forward for AI-assisted development.
I know Mehdi well. He and his co-founder (Nafis) have been heads down building for a long time. Third PH launch. Best one yet.
Hereβs whatβs always frustrated me about AI coding tools: They write the code. Then they stop.
The moment something breaks β a failed build, a missing dependency, a cryptic error log β itβs back on you. Youβre still the debugger. Youβre still the one closing the loop.
CatDoes v4 changes that dynamic.
The new agent runs on its own cloud machine. It doesnβt just generate β it:
β Installs dependencies on its own
β Runs the build
β Reads the error logs
β Fixes what broke. In a loop.
You tell it what to build, close the tab, and come back when itβs done.
Thatβs not a code generator. Thatβs agent autonomy.
And itβs the closest thing Iβve seen to a tireless dev running in the background while you focus on what actually matters.
Big congrats to Mehdi and Nafis and and the CatDoes team π Three launches in and they keep raising the bar.
Check it out and drop your questions and feedback below π
I am seriously impressed.
I had a few design ideas for my business and they were laying down in my Figma untested. I used Catdoes v4 and tada πͺ. Kudos team!!!

@khashayar_mansourizadeh1Β Thank you Khashayar, It means a lot.
CatDoes
Thank you for the comment @khashayar_mansourizadeh1Β
We're a big fan of Starnus here! π
Congrats β really excited about this release! I built a couple of portfolio apps with CatDoes v3, and even without diving deep yet, this already looks super impressive.
CatDoes
Thank you @sinan_ugurdagΒ , this is what we like to hear! π

@sinan_ugurdagΒ Thank you Sinanπ
Is it good enough to deploy to public for non software engineer? Or is it only for vibe coding?
CatDoes
it is @linkun_dongΒ !
please give it a try and let me know how it goes!
CatDoes
@linkun_dongΒ It's made for non-technical people. We have business owners, product managers, and designers who use CatDoes to build apps and websites. Give it a try and let me know if you need any help.
does it support like all Apple platforms?
CatDoes
yes @zabbarΒ , it supports both iPhone and iPad apps.
And the best part is, you don't even need a mac or Xcode to publish your app on the app store.
