What is fabro?

Fabro is the open-source dark software factory—a Rust CLI and API server for orchestrating AI coding agents via Graphviz DOT workflows. Define pipelines with branching, loops, human approval gates, and verifications; agents execute in isolated Daytona cloud sandboxes, checkpointing Git changes at every step. A React web UI tracks runs, previews ports via `fabro preview`, and generates automatic retrospectives, all from a single binary with no runtime deps.

Why is it gaining traction?

It bridges chaotic agent REPLs and untrusted diffs by making workflows diffable code—route tasks via CSS-like model stylesheets (e.g., cheap models for planning, frontier for coding), intervene mid-run, and layer linters/LLM judges. GitHub integration, SSH access (`fabro ssh`), and 24/7 queuing stand out for scaling without babysitting, plus token savings from fallbacks. At 395 stars, it's hooking dark software engineering teams tired of ad-hoc prompts.

Who should use this?

Expert engineers chaining LLMs for repo tasks like drift detection or feature impls, especially those needing human-in-the-loop without constant monitoring. Teams sharing workflows as Git files, or solo devs securing untrusted agent code in sandboxes. Avoid if you're just dabbling in one-off prompts.

Verdict

Promising for dark software factory workflows, with solid docs and DOT simplicity, but 1.0% credibility score and low stars signal early maturity—test in a side project first. Self-host via `curl https://fabro.sh/install.sh | bash` if AI agents are your bottleneck.
