Everything you need
Everything a production SaaS needs — architected correctly from day one.
RBAC + Middleware
Platform roles (USER, ADMIN, SUPER_ADMIN) and org roles (OWNER, ADMIN, MEMBER) enforced at Edge — no DB call needed.
Stripe Billing
Checkout, customer portal, and 5 idempotent webhook handlers. Plan limits enforced server-side. MRR in admin panel.
Team Management
Invite by email — even users who haven't signed up yet. Pending invite flow with email + token. Role changes, removal.
API Keys
Generate scoped API keys (SHA-256 hashed, never stored plaintext). Revoke, track last-used. Per-plan limits enforced.
Transactional Email
5 React Email templates — welcome, invite, subscription, cancellation, payment failed. Idempotent via Resend.
Admin Dashboard
KPIs: users, orgs, MRR, subscriptions. Recharts analytics: signup trend, plan distribution, top events. Paginated audit log.
i18n (EN + ES)
next-intl v4. URL-based locale detection. Add any language in 4 steps. All UI strings translated.
Dark Mode
next-themes with system preference detection. Persisted across sessions. Toggle in sidebar.
CI/CD + Docker
5 GitHub Actions workflows: lint, test, E2E, build, deploy. Multi-stage Dockerfile. docker-compose for local dev.
Rate Limiting
4 tiered Upstash Redis limiters (auth, API, strict, webhooks). Edge-compatible. Sliding window, 429 + Retry-After.
Audit Logs
Immutable audit trail with IP, User-Agent, actor. SET NULL on delete — trail preserved forever. Sentry integration.
