holaOS: holaOS is an agent environment built for long-horizon work, continuity, and self-evolution. It provides agents with a structured operating system including runtime, memory, tools, apps, and durable state, enabling them to operate continuously, evolve over time, and remain inspectable across different runs.; spring-ai-playground: Spring AI Playground is a cross-platform desktop app for building, testing, validating, and executing MCP tools in a controlled local environment. It enforces a 'No Pass, No Run' workflow where tools must pass local tests before being exposed to agents. It provides a built-in MCP server, secure secret management, and supports multiple platforms.
