REST and GraphQL APIs built OpenAPI-first. JWT or OAuth auth, rate limiting, request validation, Sentry monitoring, OpenTelemetry tracing. Documentation is generated from the spec, not the other way around.
API development at NedDev starts from €4,500 for a single-resource REST endpoint and runs up to €25,000 for a full GraphQL stack with federated services. We work OpenAPI-first, ship auto-generated SDK clients in TypeScript and Python, and monitor every endpoint from launch via Sentry and custom dashboards. An MVP goes live in 2-4 weeks.
API development is the right choice when you need your own backend for mobile apps, headless architectures, B2B integrations, or a public API as a product layer. Built with Laravel or FastAPI, GraphQL, and OpenAPI 3.1.
Our internal stack packages for multi-tenant SaaS. A Laravel + Filament starter, an audit-trail engine, and a tenant-impersonation package that runs across 12 clients.

14 EXPERIMENTS · LIVE DEMOSREST for public APIs with simple resources and wide tooling. GraphQL for frontends that combine a lot of different data or for mobile apps that want to avoid over-fetching. NedDev builds both and can also combine them via an Apollo layer.
From €4,500 for a single-resource REST endpoint, €12,000 for a full business API with auth and payments, and up to €25,000 for a federated GraphQL architecture with multiple microservices.
By default you get JWT or OAuth 2.0, rate limiting per IP and per token, request validation via JSON schema, a CORS policy, security headers, and SQL-injection protection via prepared statements. Third-party pen testing is available on request.
