Airweave

Context retrieval layer for AI agents and RAG

freemiumopen sourceupdated Apr 21, 2026

Airweave is an open-source context retrieval platform that connects AI agents and RAG systems to 50+ apps and databases through a unified search interface. It continuously syncs data from sources like Notion, Slack, GitHub, and databases, making it searchable through LLM-friendly APIs. Airweave includes Python and TypeScript SDKs, MCP support, and a CLI for managing data connections.

Airweave solves the data connectivity problem that every RAG system and AI agent faces: getting up-to-date information from the dozens of tools and databases where an organization's knowledge actually lives. Instead of building custom integrations for each data source, Airweave provides a single platform that connects to over 50 services including Notion, Slack, GitHub, Jira, Google Drive, Confluence, and various databases, then continuously syncs and indexes that data for retrieval.

The platform handles the complete pipeline from data extraction through chunking, embedding, and indexing, exposing the results through a unified search API that AI agents can query naturally. MCP server support means coding agents like Claude Code and Cursor can access organizational knowledge directly. The sync engine runs incrementally, updating only changed data to minimize compute and API costs. Developers configure connections through a web dashboard, CLI, or programmatically via Python and TypeScript SDKs.

Backed by Y Combinator X25 with over 6,200 GitHub stars and an MIT license, Airweave has gained traction among teams building AI products that need access to real-world business data. The project maintains an aggressive release cadence with 457 releases and nearly 5,000 commits. For organizations implementing RAG or building AI agents that need to answer questions about internal data, Airweave provides the data plumbing that eliminates months of custom integration work.
