You know what to fix. Now you can plan, build and ship it, too.
Fei Studio already knows your app. Describe a change and it opens a merge-ready pull request in your real codebase — your engineers approve every merge.
Described in plain language. Rendered in the real app. Sent to engineering.
Trusted by 160+ product teams.
The problem
Your best ideas are stuck in someone else's queue.
You can spec a feature in an afternoon. Then it waits a quarter, behind every other ticket in the engineering backlog. The person closest to the product has no way to ship it.
The fix
A second lane to production, yours.
Ship past the queue.
Describe the change; Fei Studio builds it in your real codebase and opens a PR. The backlog stops being the only path.
Learn from real users sooner.
Release behind a flag and watch behavior while other teams are still debating in a doc.
Engineers keep the gate.
Every change is visually validated and arrives as a review-ready PR. Your engineers approve the merge — that control stays theirs.
