The problem

Writing code got 10x faster.
Shipping stayed the same speed.

1

The queue

Every change goes through engineering. A PM specs a feature in an afternoon, then watches it wait in the backlog for a quarter.
2

The wrong stage got faster

AI coding tools make your engineers faster. Only engineers can ship, so the backlog keeps growing anyway.
3

Prototypes that go nowhere

App builders produce demos that can't touch your real codebase. The work gets redone from scratch, or dies.

Why not just use Claude Code, or any coding agent?

Same model. Different environment — Fei ships it.
A coding agent Fei Studio
Your PM describes the change ↓ It writes the code ↓ Your engineer's plate An engineer sets up the environment ↓ An engineer reviews and fixes the code ↓ An engineer ships it
Work bounces back to engineering.
Your PM describes the change ↓ Fei writes it, renders it, and validates it ↓ Fei opens a PR ↓ Your engineer clicks approve.
Ships with one approval.

For your engineers: Fei Studio runs inside Claude Code, Cursor, or any agent over MCP — their tools, plus Fei Studio's delivery layer.

The fix

Product and design build it.
Engineers approve it.

1
Built into your real codebase
2
The people who spec it, ship it
3
A second lane to production

Connect your codebase. Run a task. Get a PR.

Codebase ingestion

Your real stack. Understood in under 2 minutes.

Fei Studio plugs into your repo and models how your engineers write code - components, standards, design system, APIs, hooks, and architecture - so every task is built like your team would, not a generic AI template.
  • Connect your git provider, no manual config
  • CSS, API, SSO, DB connections - all ingested
  • Self-updating as your codebase evolves
Codebase ingestion — Fei connecting to Libs, CSS, API, SSO, DB, and Hooks

Task Execution

Turn ideas into production-ready product updates

Fei Studio takes raw product ideas, whether from prompts, screenshots, or Figma, and turns them into codebase-aligned variants and testable implementation options before generating production-ready output.
  • Any input - PRDs, screenshot, tickets, Figma etc
  • Break ideas into structured plans based on your infra
  • Translates plans into real system changes & PRs
Task execution — 36+ orchestrated steps per task with transparent output

Production Grade

Handoff output engineering can actually review and ship

Every task produces production-ready code, a clean PR, and full specs, all built to match your codebase, so engineering reviews and merges.
  • Production quality code generated to your standards
  • Clean PRs ready for engineering review
  • Full specs and change history for complete context
Production-grade code — typed, lint clean, generated to your standards

Inside the OS

Six capabilities, perfectly orchestrated.

Codebase Ingestion

Connects to your Git repo and automatically maps CSS conventions, API patterns, hooks & events, third-party libraries, project architecture, and rendering config — in under 2 minutes.

Task Execution

One task request triggers up to 40+ internal agent steps. Fei handles the orchestration end-to-end. Pricing is per-task - not per step, not per seat.

Triple Output Per Task

Every completed task produces a visual prototype, production-quality code written to your org's actual standards, and a full spec doc plus pull request ready for engineer review.

Agent Knowledge Hub

As your codebase evolves, Fei updates its understanding in near-real time. Agent context stays current without any manual maintenance or re-ingestion.

Self-Updating

Spot issues, apply fixes, add validations, and push features forward by resolving problems directly instead of handing off work to developers

Explorer Mode

Coming Soon

Planned connectors to Amplitude, Mixpanel, and call recordings - giving agents business-level context, not just technical context. So the AI knows why a feature matters, not just how to build it.

Our own product, our own codebase

Our product team. Zero code written.
100% merged.

Our product team has opened 50+ PRs against our production codebase, writing zero code. An engineer approved every merge.
