About witr
witr is an open source, Apache 2.0 licensed Go tool with both a command line interface and an interactive terminal UI that traces any process, port, container, or file back to the exact chain of systems that started it, and it is built for operators, SREs, and developers who need to answer "why is this running?" during debugging and incident response.
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.
