About OpenObserve
OpenObserve is an open source observability platform for logs, metrics, traces, analytics, Real User Monitoring, session replay, pipelines, SLO, and LLM observability.

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.
