The problem

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

1The queue

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

2The wrong stage got faster

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

3Prototypes that go nowhere

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

We already have Claude Code. Why Fei?

Same starting point. A coding agent hands the work back to engineering. Fei Studio hands them one click.

A coding agent
Fei Studio
Your PM describes the change
…waits in the engineering queue
It writes the code
…waits for an engineer to pick it up
Your engineer's plate
Sets up the environment
Reviews and fixes the code
Ships it
…the result misses what the PM actually meant
Round two, back through the queue
Your PM describes the change
minutes later…
Fei writes it, renders it, and validates it
Fei opens a PR
Your engineer clicks approve.
That's the whole path.
Work bounces back to engineering
Ships with one approval

The fix

One loop, on your codebase.

Product and design build it. Engineers approve it. The whole loop runs as one system.

1
Connect

Git provider in, codebase understood in minutes, kept current on every task.

2
Describe

A ticket, a PRD, a screenshot, a Figma frame, or a Discovery brief.

3
Build and verify

Real components, real tokens, rendered and checked in your running app, shareable preview link.

4
Ship

A review-ready PR, your engineer approves, flag it, measure it, feed the result into the next task.

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
Review, approve, ship — PR from Fei reviewed by your engineer with one-click approve

And the loop now starts before the ticket: Discover Mode researches your analytics, tickets, and customer calls to find what to build, and every merge makes the system smarter. The whole way of working is Autonomous Product Delivery.

After it ships, Fei Studio measures the result and proposes the next build. See the full loop →

Our own product, our own codebase

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

Our product team opened 80+ PRs against our production codebase. An engineer approved every merge. No one on the product team wrote a line.
