The Kin ecosystem

One system. A few clear surfaces.

Kin is one system, not a shelf of separate products. Each repository below has one job in that system. Kin's semantic graph connects the engine, optional filesystem projection, editor, and bundled agent surface. Install one system, not a pile of unrelated tools.

Kin is open-source developer tooling. KinLab adds hosted collaboration, shared memory, and team controls. The open-source Kin repositories below are free to adopt under Apache-2.0. Kin is built from them. KinLab is the hosted team product.

Kin: the system of record

Kin is the system of record for AI-written software. Kin keeps a persistent graph of entities, relationships, changes, and history.

kin-dbApache-2.0

kin-db: the semantic engine

An embedded graph engine, not a server you run.

kin-vfsApache-2.0

kin-vfs: transparent projection

Serve graph-backed files to ordinary filesystem tools.

kin-editorApache-2.0

kin-editor: the editor surface

Kin in your editor, not a fork.

kin-mcpApache-2.0

kin-mcp: the agent surface

Semantic context for any AI agent, over MCP.

kin-modelApache-2.0

kin-model: canonical types

The shared vocabulary of the graph.

kin-lspApache-2.0

kin-lsp: type-resolved enrichment

Type-resolved relationships for the graph.

kin-blobsApache-2.0

kin-blobs: content storage

Content-addressed storage for Kin.

kin-searchApache-2.0

kin-search: lexical retrieval

Lexical search under the graph.

kin-vectorApache-2.0

kin-vector: vector retrieval

Semantic vector search under the graph.

kin-inferApache-2.0

kin-infer: local inference

Pure-Rust embeddings, computed locally.

Private proof infrastructureexternal access pending

Internal supporting repositories are documented for architecture clarity, but they are not publicly readable or forkable today.

kin-benchPrivate support

kin-bench: proof harness

Pinned proof infrastructure. Public access is pending.
