arkon vs utopia
Self-hosted enterprise knowledge hub + MCP server: an LLM pipeline compiles SOPs and docs into a traceable, human-reviewed wiki, then serves it to AI clients scoped by department and role. — versus — DeepLethe's open 'enterprise world model': one Rust binary plus Postgres running a bitemporal knowledge graph with ontology packs, cited hybrid search, an agent harness and MCP. Air-gap ready.
Both are self-hosted enterprise knowledge hubs with an MCP server. Arkon compiles SOPs and docs into a traceable, human-reviewed wiki; Utopia stores facts in a bitemporal ontology-typed graph and answers with citations.

arkon — the curator's take
The MRP pipeline is the differentiator: instead of chunk-and-index, documents are compiled into merged, source-traceable wiki pages behind a plan-review gate — knowledge management, not just retrieval — with department-scoped serving over one MCP endpoint. When NOT: the license is NOASSERTION, a real blocker for the enterprises it targets — clarify before adoption; ★1.2k young, and the compile-everything approach costs LLM tokens where a plain vector store costs none.
utopia — the curator's take
For a company that wants a governed knowledge base its agents can trust, on its own hardware: ingest PDFs/Office/Markdown and sync sources (GitHub, Jira, Notion, S3), extraction follows an ontology you pick at creation (schema.org, W3C Org, PROV-O, FOAF, IOF ship in the binary), facts are bitemporal so you can ask what was known as of a date, and a built-in agent walks the graph with the same read-only tools exposed over MCP. Tantivy full-text is embedded, vectors go in pgvector, the job queue is a table — nothing else to run. NOT a memory layer for an agent app (it is a product, not a library) and not for a single person's notes: the ontology and audit machinery only pay off when several people and agents share the knowledge.
