Initialization

Fei Studio maps your codebase, CI/CD, and workflows

Fei reads your repo structure, components, CI/CD, and workflows to align with how your team builds and ships, so the code it generates follows your standards and fits your process without rework.

Workflow

Product work comes in as complete PRs

Changes arrive as structured pull requests that follow your standards. You review, request changes, and merge, instead of building from specs or tickets.

Control

You decide what gets shipped

Everything goes through your existing review process. Nothing bypasses engineering, and every change meets your standards before it’s merged.
