Sync

Local-first harness that lets you review and approve AI-agent code block by block.

Desktopfreeglobal

Sync is a free, open-source, local-first harness for steering AI coding agents. It has an agent draft a spec, build against it on its own branch, and explain the resulting changes block by block so a developer can review and approve them before anything merges. It runs on an existing agent subscription rather than requiring a separate account or paid tokens.
