Why Tempolabs apps benefit from a senior-engineer audit

Tempolabs (tempo.new) is one of the strongest visual-AI builders for shipping React apps fast. The output is structured and readable, which makes it a great starting point — but the same speed that makes Tempo useful also skips the production-readiness work a senior engineer would add. We routinely find Tempolabs apps with permissive default auth scopes, components that look great empty but break with real data, and Stripe/Supabase integrations that work but skip the hardening basics. Each is fixable in minutes with the right prompt.

Top issues we find in Tempolabs apps

Generic-but-true patterns from our audit pipeline. The audit flags these on YOUR specific project with file-and-line citations.

high

Components break under real data

Tempo's preview uses friendly placeholder data. Once you connect a real Supabase or API source, lists overflow their containers, long usernames truncate strangely, and missing fields render as 'undefined'.

Fix: Test every component with the longest realistic content + missing/null fields. Add explicit fallbacks (e.g. `{user.name ?? 'Anonymous'}`) and CSS overflow handling.

high

Permissive default auth — protected pages reachable without login

Tempolabs often wires auth at the component level instead of the route level. The result: typing the protected URL directly (skipping the login flow) lets unauthenticated users hit the page.

Fix: Move auth gating to middleware.ts (Next.js) or the Route Handler. Component-level checks are too easy to bypass.

high

Stripe integration missing webhook signature verification

Tempo gets the Stripe Checkout flow working, but the webhook handler often skips signature verification — meaning a forged event can unlock features without payment.

Fix: Use stripe.webhooks.constructEvent with STRIPE_WEBHOOK_SECRET in the webhook route. Reject any event that fails verification.

medium

Image and asset CDN not configured — slow loads on mobile

Default image handling serves full-resolution PNGs from the origin. Mobile users on 3G hit 4-6 second load times.

Fix: Use next/image with the production sharp installation. Or move images to Cloudinary / imgix / Vercel's image optimization.

medium

No error boundaries — a single broken component crashes the app

When any single component throws in production, the entire page goes white. There's no fallback, no error reporting, and no recovery.

Fix: Add app/error.tsx (Next.js) or wrap each major section in an ErrorBoundary. Log errors to Sentry or PostHog so you find out before users do.

Example fix prompts you'll get

Every finding ships with a paste-ready prompt for Cursor or Claude. Here are three examples we'd typically hand back for a Tempolabs project.

Prompt 1

For every React component that renders user data, add fallback handling for null/undefined fields and a max-width with text-overflow: ellipsis on usernames, emails, and any user-supplied string. Test with the longest realistic content.

Prompt 2

Move all auth gating from component-level checks to middleware.ts. Create a list of public routes; everything else requires a valid session. Test by visiting protected URLs directly while logged out — they should redirect to /login.

Prompt 3

Verify the Stripe webhook handler at app/api/stripe/webhook/route.ts uses stripe.webhooks.constructEvent with the STRIPE_WEBHOOK_SECRET. Add a 400 response for any event that fails signature verification.
