Buntime

#bun #hono #runtime #kubernetes #typescript

Buntime is a Bun runtime, built at Zomme, for running applications in an isolated worker pool. It adds a plugin system and a micro-frontend shell, and is operated through a web control panel. The codebase is a monorepo covering the runtime, the control panel, the core plugins, and the Helm charts.

What it does

Buntime runs applications as workers in an LRU-managed pool. Workers can be ephemeral or persistent, and each is isolated. It is built on Bun and Hono. A plugin system provides the platform capabilities through auto-discovery, onInit/onRequest/onResponse/onShutdown hooks, a service registry, and persistent or serverless modes. A micro-frontend shell hosts operator and application UIs via iframes.

Components

  • Runtime — worker pool, multi-layer routing, REST API, and service discovery.
  • CPanel — operator SPA (React + TanStack Router) for managing workers, plugins, and API keys.
  • Plugins — gateway, proxy, deployments, vhosts, authn (OIDC/JWT), authz (XACML), logs, metrics.
  • Data — @buntime/keyval (Deno KV-like), Turso/libSQL, and a multi-adapter database layer.
  • Ops — Helm charts for Kubernetes, Docker images, dual versioning, and CI release flows.

Stack

Bun, Hono, TypeScript, Biome, and Playwright, with shared packages published to npm (@zomme/bun-plugin-*) and JSR (@buntime/shared). It is deployed on Kubernetes via Helm.
