Open source · MIT License · Runs on a Raspberry Pi
Bun's native SQLite driver with zero FFI overhead. WAL mode for concurrent reads. No external database server — your data lives in a single file.
Server-side .htx templates with declarative data queries, computed properties, component composition, layout inheritance, and expression evaluation.
Server returns HTML fragments, htmx swaps them in. No JSON serialization, no client-side rendering, no SPA complexity. Progressive enhancement built in.
JWT-based prepare/execute CSRF protection. One-time tokens, replay guard, record scoping, expiration. Security without sessions.
Serve documentation from flat .md files with YAML frontmatter. Zero-config content authoring — write markdown, see it rendered.
bun create hypermedia-app scaffolds a full project. Dev server with diagnostics. Showcase and minimal variants.
No compilation. No virtual DOM. No hydration. Templates go in, HTML comes out.
