REST vs GraphQL — when should I use each?

REST suits straightforward CRUD and resource-heavy apps. GraphQL excels when clients need flexible queries, reduced over-fetching, and a strong type system. We help you choose and can support both.

We implement JWT or OAuth2 for auth, RBAC for permissions, rate limiting, input validation, HTTPS, and CORS. For sensitive data, we add encryption and audit logging.
