    Very good

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

    Practical uses

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

    Pros and cons

    What Redis does especially well — and the limits to anticipate.

    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.

    Redis: when it makes sense.

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

    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 on Redis.

    Why this verdict

    Very good

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