    Redis makes sense for real-time, high-performance caching and AI projects; for a classic CRUD app, a traditional database fits better.

    About

    In practice. What you can do with Redis.

    Key-value store for cache, queues, rate limiting, and sessions.

    Practical uses

    • Cache frequent query results.
    • Store user sessions and tokens.
    • Add vector search to an AI app.
    • Implement a leaderboard/scoring system.

    Features & use cases

    Pros and cons. What Redis does well, and what to expect.

    Pros

    • Extremely fast performance (sub-millisecond).
    • Free open-source and production-ready.
    • Rich ecosystem (caching, sessions, search, streaming).
    • Flexible deployment options (managed, on-premise, open-source).

    Cons

    • In-memory (volatile data without persistence).
    • Learning curve (specific data structures).
    • Redis Cloud can be costly at high consumption.

    When it makes sense. Keep Redis, or challenge it?

    Keep if

    • You need high-performance caching or session storage.
    • You're working on AI/ML projects with vector search.

    Challenge if

    • You only need a classic database (PostgreSQL suffices).
    • You're looking for a fully free production solution (self-hosted is complex).

    Our verdict. What to know about Redis.

    Why this verdict

    Excellent

    Redis is hard to replace short-term, a free tier to test before paying, clearly documented use cases.
