Playcode is an AI app builder for non-technical teams. Describe a website, portal, dashboard, internal tool, or app in plain language, and Playcode AI builds it while Playcode Cloud runs it with a real backend, database, files, HTTPS, preview links, custom domains, background jobs, WebSockets, snapshots, and rollback under current plan limits.
Playcode supports visual editing, AI chat iteration, AI-generated images, voice or text input in many languages, mobile building, publishing, and custom domains. No programmers are needed to start, and finished projects can move toward real business outcomes like leads, bookings, signups, and payments.

I completely rebuilt this sync engine + orm with relations, lazy loading etc, using Vue + Pinia in https://playcode.io. Google Linearโs videos, they explained in detail their architecture. Yes, I spent a few months. But it worth it. Every new field, model I need to add, it is so straightforward. I do love frameworks and foundations. They make live easier later by a lot. - Source: Hacker News / 3 months ago

Far beyond of 7K LoCs. So when you compare to โshitty slowโ Claude... - Source: Hacker News / 3 months ago

Most system design interviews fail because candidates draw perfect whiteboard diagrams but canโt explain the tradeoffs of their choices, or canโt write code to implement a core component. By 2025, 60% of FAANG system design interviews will require live coding of at least one component, per internal hiring data. Instead of practicing whiteboard diagrams with Excalidraw, practice coding core components: rate... - Source: dev.to / 4 months ago
