Why we deploy every change to its own URL before production, and how it changes our relationship with clients.
At Coderflight, no feature reaches production without going through a preview environment: a full copy of the application, deployed automatically for every pull request.
The pipeline, step by step
- Every push triggers checks: lint, type-checking, unit tests.
- If everything passes, the app is deployed to a unique URL (for example on Vercel).
- End-to-end tests run against that URL in a real browser.
- The client gets the link and validates the feature on their own phone.
- Merging triggers the production release, with one-click rollback.
What it changes for clients
No more waiting for "acceptance testing" at the end of the project. Feedback flows continuously, on the real app, with real test data. Misunderstandings are caught in days, not weeks.
What it changes for quality
Each change is isolated, tested and visible. Regressions are spotted immediately and production stays stable. Preview databases (Postgres branches) keep real data untouched.
What about mobile apps?
The same principle applies: automated builds distributed through TestFlight and Google Play internal testing, with over-the-air updates where possible.
Ship often, in small verifiable steps: it's the safest way to move fast.
