About SigNoz
SigNoz is an open source, OpenTelemetry native observability platform for cloud native applications. It unifies logs, metrics, traces, alerts, and dashboards into a single tool, replacing fragmented monitoring stacks with a correlated signal pipeline. It lives in the observability ecosystem alongside tools like Prometheus, Jaeger, and Grafana, and is positioned as an open alternative to Datadog.

About opensre
OpenSRE is an open source Python framework for building AI SRE agents, distributed under the Apache 2.0 license. It lives in the infrastructure and operations ecosystem, specifically the monitoring and observability space, and it describes itself as the toolkit for AI era site reliability engineering. The project is currently at v0.1 and is published as a public alpha, meaning the core workflows are usable for early exploration but are not yet fully stable, and both APIs and integrations may evolve as development continues.
