Theia
An extensible browser/desktop IDE framework (the open alternative to VS Code's proprietary extension model). Standout trait is being a true platform for building custom cloud IDEs rather than a single product.

⚙ Full Stack
TypeScript/Node.js backend process per workspace paired with a browser frontend built on the Monaco editor and a DI-based extension framework; typically run one container per user workspace with a mounted volume.
📈 Scaling Analysis
Scales by fanning out one stateful container per user rather than scaling a shared service — this works but multiplies cost and requires an orchestration layer (e.g. Theia Cloud) to spin workspaces up/down, which is real infrastructure investment beyond just running the image.
🚀 Running on Nexlayer
Needs a per-user workspace pod pattern (one Theia pod + PVC per active user session), which is resource-heavy at scale on Nexlayer; each pod's workspace files should live on a dedicated volume, not shared across pods.
