Lobu

Lobu is an open source platform that gives AI agents shared, persistent context about a person, a team or a public body of knowledge. It connects public signals with customer conversations and activity so agents can find sales opportunities, flag churn risks early and show who needs attention and why. The product is presented in three forms. A personal second brain keeps relationships, commitments and plans connected. A company brain gives a team prospects and customer health, with the context needed to follow through. A public knowledge graph lets people and their agents discover and contribute research. Agents reach this context through an MCP server, so tools such as Claude Code, ChatGPT, Codex and Gemini can query it, and the site cites more than 60 connectors including Slack, Gmail, GitHub, Jira and Notion. Users can bring their own MCP server or have an agent build a connector with the Connector SDK. A Mac app for computer use, a Chrome extension for browser use and sandboxed code with scoped access are also listed. Lobu can be self hosted for free or used through Lobu Cloud. The managed service is described as serverless and billed by usage: $0.000463 per vCPU per minute, $0.000231 per GB of memory per minute and $0.15 per GB of storage per month. Idle agents cost nothing, and billing is metered by the second only while an agent is active.
