I ported Kubernetes to the browser

2 days ago

Webernetes is a partial port of Kubernetes to TypeScript, enabling clusters to run in the browser.
It is about 140KiB gzipped and avoids WebAssembly due to size constraints, instead being a from-scratch TypeScript implementation.
The project includes features like pod lifecycles, DNS, networking, and deployments, with a browser-based image registry.
Almost all code was generated by LLMs, but rigorous manual review and integration testing against k3s were used to ensure correctness.
It includes 204 integration tests and 1,855 unit tests to validate behavior matches real Kubernetes.
The author spent two months on the project, with significant LLM token usage, costing over $1,800 in the final week.
Webernetes is intended for interactive educational content, not production, and future expansions are planned based on user needs.
