kiln vs Trail-Code
kiln: Kiln is an open-source engine and local tools that enable coding agents to build and revise 3D assets. Agents write JavaScript using Kiln's helpers, and Kiln provides rendered views and structural checks for review, supporting GLB export.; Trail-Code: Trail-Code (formerly Graft) enhances coding agents like Claude Code, Cursor, and Gemini by providing them with a contextual understanding of the codebase. This results in significantly faster, cheaper, and more accurate code generation and problem-solving, preventing agents from repeatedly re-exploring the same code.

When to choose:
- You keep correcting your agent the same way and want each lesson saved as a rule in CLAUDE.md and AGENTS.md.
- You want learnings committed in `.trail/learnings/` so the next session or a teammate gets them back.
- You want a code graph as linked markdown files, with no embeddings or server.
When to skip:
- You need independent benchmarks: the 4x cheaper and 3x faster claims are the project's own.
- You want team views without a hosted account: they need sign-in to a hosted service.
- You prefer mature tools: the repository was created in July 2026.
