requests-cache is a persistent HTTP caching library for Python's requests library, providing a drop-in CachedSession and optional global patching. It supports multiple storage backends including SQLite, Redis, MongoDB, DynamoDB, and file-based serialization, with flexible expiration via Cache-Control headers or custom schedules.

Use cases

• cache http responses in python requests
• speed up web scraping with persistent caching
• avoid re-downloading api responses
• cache requests session to sqlite
• add ttl-based http caching to python scripts
• reduce api rate limit hits with response caching

When to choose

• you already use the python requests library and want transparent caching
• you need persistent cached responses across script runs
• you want flexible expiration strategies and multiple storage backends

When to avoid

• you use httpx or aiohttp instead of requests
• you need a standalone caching proxy rather than an in-process library
• you need distributed cache invalidation logic beyond HTTP semantics
