1/x Starting my #buildinpublic journey #myelixirstatus. Basically, I'm going to periodically ramble about building my digital product in public to maybe connect or share insight with others doing the same. Journey so far:

Something I wanted to see if Claude Opus 4.5 could do: clone a fully functional Billion $ SAAS product and make it at least 100x cheaper.

The first product that came to mind was TypeForm because it's very popular, very expensive, and in theory, very simple.

The result is OpenForm: a polished + functional and Open Source Typeform clone at ~100x less cost, that can be setup and deployed in ~15 minutes. The agent building this ran for ~35 minutes.

Here are the details, technique, and the code:

Getting to the point where I just build what I want instead of searching for existing solutions. eg. I built and released https://t.co/muOzBSZyN5 in 10 mins to help me with breathing exercises (I like the graph animation way of visualising it).

[Matt Platts @mplatts]

Built a real-time AI streaming chat recipe for Phoenix LiveView using ReqLLM 🚀

Watch responses appear token-by-token instead of waiting for the full response. Includes:
• Multi-turn conversations with context
• Auto-scroll & visual indicators
• Error handling & retry logic
• Reusable components

@mikehostetler Nice work... just used this in a recipe https://t.co/uJ6hslS4Xj

[Matt Platts @mplatts]

not long left before we're all unemployed - yay

[Matt Platts @mplatts]

https://t.co/Klt3oRJATp is crazy good. build your phoenix web app from inside your browser - the AI has access to logs, can click around your app, access your db etc.

@rohanpaul_ai what site generates the music?

[Matt Platts @mplatts]

Augment code still clearly the best coding agent. I've tried a lot.

[Matt Platts @mplatts]

Suno is great... anyone can be a music artist now. https://t.co/WrI8QRCv60
