What are some alternatives to Flask-Limiter for rate limiting in Flask?

There are several alternatives to Flask-Limiter for rate limiting in Flask applications. Some popular options include Redis-based rate limiting, Flask-RateLimit, and using middleware like Flask-Limiter with custom backends.

Can you tell me more about Redis-based rate limiting?

Redis-based rate limiting uses Redis as a data store to keep track of request counts. It allows for distributed rate limiting across multiple instances of your application, making it highly scalable.

What about Flask-RateLimit? How does it work?

Flask-RateLimit is a simple extension that provides rate limiting for Flask applications. It works by decorating your view functions with a rate limit, which is enforced using in-memory storage or a custom backend.

Are there any performance considerations I should be aware of?

Yes, performance can vary based on the storage backend you choose. In-memory solutions are faster but not suitable for distributed systems, while Redis offers better scalability but may introduce some latency.
