CodeSandbox (OSS)
The open-sourced pieces of the CodeSandbox in-browser IDE/sandbox platform, historically best known as a hosted SaaS product. Its standout trait — the real value (instant cloud sandboxes) — largely remains proprietary/hosted rather than in the OSS release.

⚙ Full Stack
TypeScript monorepo (React frontend, Node services) that historically depended on CodeSandbox's proprietary container-sandboxing infrastructure (Firecracker VMs) for the actual code-execution sandboxes — that heavy-infra piece isn't fully represented in the public OSS repo.
📈 Scaling Analysis
The real product's scaling story (ephemeral micro-VMs per sandbox) isn't reproducible from the OSS pieces alone, so it can't be honestly evaluated as a self-hostable scalable service from this repo.
🚀 Running on Nexlayer
Self-hosting the full experience isn't realistic — the OSS repo lacks the proprietary sandbox-execution infrastructure (VM-per-sandbox isolation) that makes the real product work, so a Nexlayer deployment would only get a partial, UI-only slice of the actual SaaS.
