CatDoes v4

does it support like all Apple platforms?

Is it good enough to deploy to public for non software engineer? Or is it only for vibe coding?

Congrats — 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.

You’re bundling a full backend (DB/auth/storage/realtime/edge). How do you think about the tradeoff between “batteries included” and flexibility: what’s the escape hatch when teams need custom infra, strict compliance, or want to bring their own services—and how do secrets and production safety work with an autonomous agent?

I created my habit tracker app with catdoes, and I love it! Congrats Guys.

This product is really amazing, and I've been watching their progress. I really like the quality of the product.

Congrats, I'm so excited for this! I prototyped 2 apps for my portfolio with CatDoes v3 and now I just tried this and I can't believe it one-shotted my app. Good job team✨👌🏼

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 🪄. Kudos team!!!

Hey PH fam 👋Super excited to hunt CatDoes v4 today — 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.Here’s what’s always frustrated me about AI coding tools: They write the code. Then they stop.The moment something breaks — a failed build, a missing dependency, a cryptic error log — it’s back on you. You’re still the debugger. You’re still the one closing the loop.CatDoes v4 changes that dynamic.The new agent runs on its own cloud machine. It doesn’t just generate — it:→ Installs dependencies on its own→ Runs the build→ Reads the error logs→ Fixes what broke. In a loop.You tell it what to build, close the tab, and come back when it’s done.That’s not a code generator. That’s agent autonomy.And it’s the closest thing I’ve 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 🙌 Three launches in and they keep raising the bar.Check it out and drop your questions and feedback below 👇

👋 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 buildsMobile 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 yetWho 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 ideaProduct 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. 🙌Mahdi and NafisCo-founders, CatDoes
