SigNoz – An open source alternative to DataDog

In plain words

SigNoz is an open source monitoring and observability platform launched in 2021. It provides an alternative to commercial solutions like Datadog for tracking application performance and system metrics. Designed for developers and DevOps teams, SigNoz allows organizations to monitor their applications and infrastructure without relying on proprietary vendors. Being open source, users can self-host the platform and customize it to their specific needs.
