Build local-first products faster
Auth, sync, AI, billing, and analytics wired together.
Local-first data
Electric + TanStack DB stream Postgres to the client; writes reconcile by transaction id.
AI runtime
OpenRouter gateway, dictionary-driven model policy, structured outputs, and Durable Streams.
Auth & API
Better Auth sessions and a typed tRPC API over Hono — one boundary for all product data.
Workflows & email
BullMQ on Postgres for product-critical jobs and Resend with localized React Email templates.
Billing
Stripe checkout, portal, and signature-verified webhooks behind a single package.
Analytics & logs
PostHog-first events and feature flags, with request/workspace correlation on every log.
Everything you need, on day one.
Twelve provider-boundaried packages, six apps, and a no-skip test suite. Clone it and start shipping product, not plumbing.
