Show HN: Dyad, local, open-source Lovable alternative (Electron desktop app)

Hi HN!

I left Google earlier this year and created Dyad, a local, open-source AI app builder made with Electron.

The motivation: I tried one of the popular cloud-based AI app builders, but when I pulled down the app to run locally and debug in Cursor, it just didn’t work. So I created Dyad, an app builder that runs fully on your computer, making it easy to switch between Dyad and coding tools like Cursor or Claude Code.

Source code: https://github.com/dyad-sh/dyad/

Download (free, no sign-up): https://www.dyad.sh/

I've gotten questions about how it works under the hood so I wrote an architecture doc explaining how it does tool calling using XML tags, etc: https://github.com/dyad-sh/dyad/blob/main/docs/architecture....

Let me know what you think and happy to answer questions about building an Electron app, etc!

These things does work (up to a max few thousand lines of code), but, they eat tokens like f*ng monsters.

Thanks! Check out our Prompt Library feature: this way you can create reusable prompts across your apps: https://www.dyad.sh/docs/releases/0.18.0

I have been using it and I love it. It's isn't my main driver because I have to work on a lot of Bootstrap sites, it didn't like them the last I checked because they weren't a js framework. But I have made a few playthings with it that were and it was good.

My Kagi-fu fails me, but I recall a builder generated code use Supabase row level security, and it fails open, and no longer filtering out data from other users. Is this guaranteed to protect your data?
