About Prometheus
Prometheus is an open source monitoring system and time series database, part of the Cloud Native Computing Foundation ecosystem. It collects metrics from configured targets at defined intervals, evaluates alerting rules, and visualizes results. Designed for reliability in dynamic environments, it operates without reliance on distributed storage, ensuring each server node functions independently.

libSQL is an open source, open contribution fork of SQLite created and maintained by Turso. It lives in the SQLite ecosystem and extends the embedded database model with features such as embedded replicas and remote access. The repository also distinguishes libSQL from the separate Turso database, which is a SQLite compatible implementation written from scratch in Rust and currently in beta.
