Frameworks

These ship as examples in the playground (project picker → Examples). Unless noted, they were checked in Chrome.

Project	Status	Notes
Elysia 1.4	✅ Works	Every route returns the same status and body as real Bun.
Elysia 2 (rc)	✅ Works	Same check as above.
Hono	❔ Untested	Bun starter template, from GitHub. Listed as an example; no recorded check yet.
Lit SSR + Elysia	✅ Works	Streams Lit SSR, hydrates, uses bun:sqlite and WebSockets.
Astro + Solid	🟡 Partial	Astro 7 dev server, on-demand pages, a hydrated Solid island and an API route. HMR and the dev toolbar are off.
Vite	🟡 Partial	Vite 8 dev server, started from a script with createServer(). HMR connects over the preview’s WebSocket; not yet tested end to end.
Node built-ins demo	✅ Works	Output matches real Bun.
bun.lock demo	✅ Works	Nested installs from a lockfile.

What usually blocks a framework

• CLI scripts. Only "script": "bun <file>" runs. Start the dev server from a file instead (for example createServer() in Vite, dev() in Astro).
• Native bindings without a wasm fallback.
• Child processes (child_process, Bun.spawn) and zlib.
• Install scripts, which never run.
