AI builders like Lovable and Bolt ship code fast — but they can't test every edge case in production. DeepTracer is the AI that watches the AI's work — catches unhandled errors, API failures, and LLM cost spikes before your users notice.
STRIPE_WEBHOOK_SECRET is missing from
your Vercel environment. You added it to .env
but forgot to add it to Vercel's dashboard
before deploying.
Lovable, Bolt, and Cursor build the happy path perfectly. Production finds everything else. DeepTracer knows all three blind spots — and catches them automatically.
Your AI builder wired up Stripe, Clerk, or SendGrid perfectly. It just didn't tell you to add the API keys to Vercel — because it can't see your deployment environment.
STRIPE_SECRET_KEY returns undefined in your Vercel production
environment. The variable exists in your .env.local file but was never
added to Vercel → Project Settings → Environment Variables.
AI writes the happy path flawlessly. But real users skip steps, have empty profiles, hit rate limits, and use your app in ways no prompt described.
312 users hit this crash — all new signups who haven't completed
onboarding yet. user.profile is null until the
profile setup step is finished. Affects your entire new-user funnel.
You asked your AI builder to add a chatbot or AI feature. It did. But a bug is calling GPT-4 on every keystroke instead of on submit — and your bill is running at $40/hour.
Your AskAI component fires on every keystroke
in the input field — no debounce, no submit gate. At current rate,
projected monthly cost: $2,800. Move the call to
onSubmit and add a 300ms debounce.
Lovable and Bolt apps deploy to Vercel by default. Connect your Vercel project once — no code changes, no redeploy — and DeepTracer starts watching instantly.
Every request, error, and function log from your app — automatically forwarded to DeepTracer. No code changes. No new deploys. Just three clicks in Vercel Settings.
Go to your project → Settings → Log Drains. Takes 10 seconds to find.
Copy the URL from your DeepTracer dashboard and paste it in. Select all log sources.
Click Save. Your agent starts watching immediately — no redeploy needed.
If your Lovable app uses OpenAI, Anthropic, or any AI feature, add 5 lines of code to track LLM costs per user, distributed traces, and custom events.
Every monitoring tool tells you something broke. DeepTracer tells you why it broke, who it affected, and exactly what to change to fix it.
No stack trace archaeology. No Googling the error. No guessing which deploy caused it. Just open the investigation and read the fix.
