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. The same graph runs underneath every surface: an embedded engine, a transparent filesystem projection, editor and agent integrations. 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 KinLab control plane is the commercial layer on top.
Open sourceApache-2.0
The substrate, in the open. The engine, the projection, retrieval, inference, and the editor and agent surfaces, each its own repo on github.com/firelock-ai.
