    Why switch from Firebolt

    In-process analytical database for single-machine work, free and MIT licensed.

    Pros

    • Runs in-process with no server to install or manage
    • Queries CSV, JSON, Parquet and Iceberg files directly
    • Clients for Python, R, Java, Node.js, Go, Rust and more
    • MIT licence, governed by an independent foundation

    Cons

    • Not built for many concurrent writers or high-volume transactional apps
    • Single-machine engine; scaling beyond one host needs other tools or a hosted service
    • No built-in GUI; you need a client tool or notebook for visual work
