Frequently Asked Questions
What is the best free API testing tool?
Hoppscotch (web-based, open source) and Insomnia (desktop, open core) are both excellent free options. Postman's free tier is also generous for individual developers.
Do I need an API gateway?
If you have multiple microservices or need centralized rate limiting, authentication, and logging, yes. For simple applications with a single backend, your framework's built-in middleware is usually sufficient.
How do I keep API documentation up to date?
Use an OpenAPI specification as the single source of truth and auto-generate documentation. Tools like Swagger and Postman can publish live docs from your spec file.
