Trellis

The best agent harness.

Make AI coding reliable at team scale. A team AI coding harness for progressive specs, custom workflows, task context, and memory across Claude Code, Cursor, OpenCode, Codex, Kiro, Kilo, Gemini CLI, Antigravity, Windsurf, Qoder, CodeBuddy, GitHub Copilot, Droid, and Pi Agent. It has reached 8,380 GitHub stars, written primarily in TypeScript.

Why now: Recent coverage — "Víctor Falcón (@developer.joy) on Threads" — alongside renewed developer interest is driving current visibility.

• 8,380 GitHub stars, 459 forks — verifiable at github.com/mindfold-ai/Trellis.
• Primary language TypeScript; topics: agentic-coding, ai-workflow, claudecode, codex.
• Licensed AGPL-3.0.
• Third-party coverage: "Víctor Falcón (@developer.joy) on Threads".

Considerations: Solid adoption (8,380 stars) but quiet cross-source signal right now — established utility more than a current breakout.

EARLY MOMENTUM · Research: Adoption is real but cross-source confirmation is thin — a short hands-on trial (TypeScript) will tell you more than the metrics.
