AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

fakeredis is a pure-Python, in-memory implementation of the Redis protocol that serves as a drop-in replacement for redis-py, enabling Redis-dependent code to run in tests without a server.

Low friction installation with three lightweight runtime dependencies (redis, sortedcontainers, typing-extensions). The package is actively maintained with a recent release 22 days ago and has been stable since 2012.

BSD-3-Clause is a permissive license that allows commercial and private use with minimal restrictions, requiring only preservation of copyright and license notices.

Usage

pip install fakeredis

import fakeredis

r = fakeredis.FakeStrictRedis()
r.set("foo", "bar")
print(r.get("foo"))  # b'bar'

Verdict: fakeredis is a mature, actively maintained testing utility with no known vulnerabilities, permissive licensing, and low install friction. It is well-suited for developers who need Redis-compatible in-memory testing without server overhead.

Needs verification
