$ Vocare · Tech Stack
The converged siloes stack as it applies to Vocare, plus the Vocare-specific items beyond that shared baseline. Notably, Vocare is where this stack was discovered, not designed top-down — Farpost's rebuild adopted it after finding it already working here.
## SHARED_SILOES_BASELINE
- Fastify — the API framework.
- Drizzle — the ORM layer over Postgres.
- Postgres — the database.
- better-auth — passwordless magic-link authentication, extended with Vocare's own
additionalFields(entitlement status, date of birth, country, paid-at) rather than a separate profile table.
## VOCARE_SPECIFIC_ADDITIONS
- Web Speech API / Expo speech recognition — voice capture for the conversation engine, with a typed fallback.
- Stripe — the $29 one-time paywall, currently running in test mode.
- Expo — the mobile shell underlying both voice capture (M3) and the planned Android packaging (M10).
- An LLM API — powers the conversation engine and the async post-session mining pipeline that extracts coaching signal without ever scoring a session in real time.
