TL;DR
fessRAG / Knowledge Base · ★ 1.1k
Implement an internal enterprise search engine for documents, files, and databases
pipeshub-aiRAG / Knowledge Base · ★ 3.8k
When to choose:
- Knowledge is spread across Slack, Drive, GitHub, Microsoft 365, Notion and other tools, and you want one search with citations.
- Answers must respect each person's access: permissions are checked against the source system at query time.
- You want to self-host with your own LLM provider and give the same context to agents through MCP.
When to skip:
- You only need one app such as Jira or Slack: a single MCP server is far lighter.
- You cannot run several services (graph database, message broker, key-value store) on a properly sized server.
- You want a managed cloud version: the README lists it as coming soon.
