Codebase Health Check: Know the State of Your AI‑Generated App
Before you scale or fundraise, you need to know whether your app can handle more users and more features. A health check is a quick, structured look at the areas that predict stability and speed. For vibe‑coding and no‑code teams, it’s a way to turn hunches into a clear plan.
What to look at
- Core journeys: sign‑up, sign‑in, and a simple save are reliable on the live site
- Structure: shared components exist for repeated screens; names are clear
- Errors and empty states: users get guidance, not blank pages
- Settings: development and production match; secrets and URLs are aligned
- Tests: a few integration tests protect the journeys you rely on
A quick scoring approach
Rate each area from 1 to 5. Anything below 3 needs a small, actionable improvement. The aim is to create a short list you can address alongside features.
What good looks like
Users can complete the main job on the live site without help. Labeling and navigation are predictable. Deploys are calm because settings are consistent. When a bug appears, you can reproduce it and land a fix in a day.
How to improve without stopping
Adopt a “one fix per feature” habit: as you ship something new, tidy one area of friction. Remove duplication. Add a missing error. Align a setting. Over a few weeks the health score rises without a big detour.
Tools that help
Cursor and Claude Code can find and consolidate repetition. Copilot speeds up small improvements. Vercel’s previews let you test on live infrastructure before you share a link. Supabase or Firebase keep auth and data simple while you focus on outcomes.
If you want a second set of eyes to run a quick health check and propose a short, high‑impact plan, Spin by fryga can help you prioritize and execute without losing momentum.
A health check is not a grade; it’s a map. Use it to guide steady improvements that users can feel.
Founder FAQs
How long does a health check take? A lightweight pass can be done in a day or two, with clear actions you can start immediately.
Do we need one before fundraising? If investors will ask about stability and roadmap, yes. A concise report shows you understand risks and have a plan.
Can we do it ourselves? Yes. Use a checklist, get a second set of eyes, and be honest about weak spots. If time is tight, a professional pass speeds this up.
Case study: confidence before a launch
Before a public launch, a founder ran a health check. They found three repeated screens, a missing error page, and a deploy setting mismatch. After consolidating components, adding a friendly error, and aligning settings, the launch was calm and support volume stayed low.
A self‑check you can run this week
- Live journeys: can a new user sign up and reach the dashboard?
- Consistency: do the same actions use the same labels and routes?
- Errors: do screens guide people when something fails?
- Settings: do development and production share the same URLs and keys?
- Tests: do two tiny integration tests pass on each preview build?
Answering these with “yes” is a strong signal your AI‑generated app is ready for the next cohort of users.
