PROJECT / KINEWEFT · OPEN SOURCE

Motion design.
Structured for tools.

An early-stage open-source motion engine built by Ephyro. Kineweft makes compositions editable through both a command line and AI-agent tools, using the same validated project operations.

Kineweft motion-design workspace with a composition preview, structured scene data, and a render timeline.

One project format. More than one way to edit.

A versioned JSON document describes the composition. The CLI and Model Context Protocol (MCP) server use the same validated operations to inspect and modify it, so edits stay explicit and reproducible.

Projects are data rather than executable code. Rendering runs locally; the core workflow does not require a hosted service or an AI model.
