An AI agent with its own computer builds your apps
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.
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. 🙌

Who hunted CatDoes v4?
CatDoes v4 was hunted by KP. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
