Cost audits for AI-built apps
What a typical leaky AI-built app wastes while you read this page — retry loops, bloated prompts, unindexed queries, oversized servers. Illustrative, but uncomfortably realistic.
Apps built with Lovable, Bolt, Replit, and v0 are optimized to ship fast — not to run cheap. Plumb reads your real usage like a utility meter, finds every leak, and fixes it. Most audits pay for themselves in the first quarter.
These aren't hypotheticals. They're the patterns builders report — and the ones we find in nearly every audit.

THANK YOU FOR LEAKING · PLEASE DON'T COME AGAIN
Connect your app and billing dashboards read-only. We flag the obvious leaks — exposed keys, retry patterns, prompt bloat — and estimate what they cost you per month.
A senior infrastructure engineer traces every dollar: AI tokens, database, hosting, third-party APIs. You get a line-by-line map of where money goes and which lines shouldn't exist.
We ship the fixes — caching, right-sizing, prompt trims, indexes, spend alerts — and set up a meter you can actually read, so the bill never surprises you again.
The Plumb guarantee: if our audit doesn't find annualized savings of at least the audit fee, the audit is free. We've never had to honor it — leaks are that common.
Ten minutes, read-only access, and you'll know what your app actually costs to run — and what it should.
