RESOURCES / WHY
A SaaS starter
that respects
your architecture.
Most starters give you screens. UseDeploy gives you a system. Bounded contexts, ports & adapters, an event bus, a typed permission matrix — the foundations you'd build anyway, already built.
The honest pitch.
You can build everything UseDeploy ships in three to six months. The question is what you'd learn doing it. If the lessons are interesting (a novel DSL, a hard distributed-systems problem) — build it. If the lessons are boilerplate (HMAC webhook delivery, OAuth flows, GDPR deletion lifecycle) — buy the boilerplate and ship the interesting part.
What you get on day one.
A working DDD layout
Bounded contexts, layered modules, ports/adapters. ESLint flat configs enforce the boundaries.
Three payment providers
Stripe, MercadoPago, Polar — switch with one env var. One IPaymentProvider port behind them.
Auth that meets compliance
argon2id, 2FA, password reset, rate limits, audit log — all wired and tested.
Webhook delivery + receiver
BullMQ, HMAC, retries, DLQ. Receivers verified with a 5-line helper.
GDPR by design
Consent, export, 30-day-grace deletion, audit anonymization. Not bolted on.
AI-streaming endpoints
Vercel AI SDK + Anthropic. SSE streaming, tools, structured output, per-org budgeting.
Why DDD?
Domain-Driven Design isn't a religion — it's a way to keep the domain readable as the codebase grows. UseDeploy's layout means the domain layer is a pure description of your business: no Express, no Prisma, no SDK imports. Tests are fast. Onboarding is faster. Refactors don't cascade. After a year, the code still tells you what the system does.
Why AI-readable?
Claude Code, Cursor, and other agents work better with explicit conventions than with implicit ones. AGENT.md and CLAUDE.md files document bounded contexts, forbidden patterns, and the WHY of each decision. The agent reads them once and stops hallucinating types. You spend your time reviewing diffs, not re-explaining architecture.
Skip 6 months. Keep your architecture.
A typed, tested, documented foundation — yours forever for one fee.
