One system.A few clear surfaces.
Kin is a system, not nineteen products. The expensive failure is rarely in the file that changed. Files compile locally; systems break relationally. Graph-owned truth sits beneath the engine, optional filesystem projection, editor, and bundled agent surface. You adopt one substrate, not a pile of tools.
Open-source Kin substrate, hosted KinLab control plane. Adopt the tooling for free, scale on the platform. The open-source Kin repos below are the wedge: free to adopt, Apache-2.0, and dogfooded. We build Kin with Kin. The hosted proprietary KinLab control plane is the commercial layer on top.
Open sourceApache-2.0
