Kshitij and Rahul here. We're building Playground, an open-source sandbox that lets your non-technical teams prototype directly on production codebases, without bugging you (developers) to spin up and maintain another repo.The repo is here: https://github.com/B1u3B01t/design-playground.We've been working together for six years. Last year we built an AI design agent because we thought designers were the biggest bottleneck. But we were wrong.After talking to teams, we realised designers, PMs, founders and even sales people all wanted to quickly change and explore flows for their users, that looked and behaved like the real app.But devs don't trust non-technical teams to work on production and not fuck up the code. Agree. So the other way is setting up another mock repo.And that defeats the point. It adds maintenance cost of keeping both in sync. This is what happened when both of us were working together too. So we built an open-source Playground.It has all the features out of the box: super intuitive, good ux, links to claude/codex, latest features, easy additions of skills, collaborative and best of all, safe guardrails so if you want, you can get the code in one click (unlike figma or other closed source shit).I work on the Playground. Rahul on Conductor. We're super claude pilled and believe in this duo being the new product team size, something coinbase and square are already doing with "pods".Right now it supports Nextjs projects. We will definitely add more frameworks and improve the developer experience. We'd especially love feedback from teams already maintaining internal sandboxes.Go let your non-tech team play.

Could you build this?

Partial The front-end prototyping canvas can be built quickly, but dynamically loading and isolating arbitrary production codebases without breaking builds requires complex sandbox infrastructure.

What it would actually take: The core system requires an isolated sandboxing environment (like WebContainers in browser or ephemeral remote containers via Docker/Firecracker), an AST parser (Babel/SWC) for hot-patching UI code in memory, and dynamic module resolution. The hardest parts are bundling dependencies dynamically and safely isolating state updates against proprietary codebases.
