InfluxDB
Monitoring & StatusPurpose-built time series database for metrics and events
Replaces Datadog, AWS Timestream
AWS Timestream is a popular proprietary tool in the monitoring & status space. These open-source apps let you replace AWS Timestream with software you host and control yourself.
Moving off AWS Timestream means trading a managed subscription for a service you run yourself. The payoff is ownership: no per-seat pricing, no vendor lock-in, and full control of your data. Start with the option above that matches your setup-difficulty comfort level — every app links to a detailed specs page and head-to-head comparisons.
