Built your app with Lovable, Bolt or v0?

Your AI built the app. What'll it cost when it grows?

Vibe-coded apps quietly run 5–10× their advertised price. You find out from the invoice.

clearlit scans your app and shows you what'll blow up your bill as you scale — the expensive stack choices and cost traps your AI left behind, with the exact fix for each.

Free cost check • Full report from $39 • No card to start

One app at 25k users dropped from ~$800/mo to ~$75/mo after one fix — $8,700/year.

Know before you owe

Launch knowing the number. Not crossing your fingers.

AI tools are great at shipping features fast. They pick whatever's easiest to generate — not whatever's cheapest to run.

clearlit finds the choices and patterns that turn a $25 app into a $600 one — before your first viral day, not after the invoice.

The problem

The app works. The bill is the surprise.

Nothing on the screen tells you a single dashboard fires 20 database reads, or that your managed hosting costs 10× a plain backend. You only see it when usage climbs — and by then it's a migration, not a setting.

Generic cloud calculators are built for engineers with spreadsheets. clearlit reads your app, finds the specific traps, and hands you the fix in plain English.

How it works

Three steps. No engineer required.

1

Start with a free check

Answer four quick questions about your stack and scale for an instant read — or connect your repo read-only for the full, line-by-line report.

2

We trace the costs

We map your stack, find the expensive choices and the queries, storage and traffic patterns that scale your bill — and where your free tier runs out.

3

You get a fix-it report

A plain-English cost verdict, your runway by user count, and a copy-paste fix prompt for each trap. Paste it back into your tool and save the money.

What we trace

Seven things that quietly grow your bill

Expensive stack choicesManaged hosting (Lovable Cloud) vs. your own backend
Costly queriesUnscoped reads, no pagination, N+1 loops that multiply reads
Bandwidth & storageImages served without a CDN, oversized assets, egress overage
Free-tier limitsWhere your Supabase / Firebase / Vercel plan runs out
Runway by usersRoughly when you cross each limit, and what the next tier costs
Function & compute wasteEdge function overuse, polling, things billed per call
Fix promptsThe exact prompt to paste into your tool to fix each one
A clear verdictLow / Medium / High bill risk — and the number behind it

Questions

Good to know

Do I need to be technical?

No. The whole point is that you don't. Every finding is written in plain English and comes with a prompt you paste straight into Lovable, Bolt, Cursor or whatever you built with. If you can vibe-code an app, you can apply the fix.

Which tools and backends do you support?

Apps built with Lovable, Bolt, v0, Replit and Cursor, on Supabase, Firebase or Vercel backends. The cost traps live in the backend, so it works regardless of which AI tool wrote the code. Built somewhere else? Send the URL — if we can't trace it properly we'll tell you before you pay.

Is this just a pricing calculator?

No. Calculators ask you to guess your usage and do the math. clearlit reads your actual app, finds the specific choices and patterns driving the cost, and tells you which one to fix first — and how.

How accurate is the number?

We give you a range, not false precision — your real bill depends on how people use your app. What we're certain about is which traps will drive the cost up and how to remove them. The savings come from the fixes, not the forecast.

Is my code safe with you?

Repo access is read-only and optional. We never store your source after the report is delivered, and you can run a URL-only check if you'd rather not connect anything.

Find the trap before the invoice does.
