★

Recommendation engine

Surfaces the cheapest option, the best quality option, and the best value trade-off automatically.

Vibe-Budget Rework

The unique aha-moment. A model with SWE-bench p=0.50 carries a 100× rework factor — making "cheap" models often the most expensive choice.

Provider filter

Compare across providers or filter to just the ones you trust. EU-hosted, US-hosted, or open-weight — your call.

Built by Christopher Siebert.

Indie iOS developer based in Hamburg, Germany. VibeQuotr exists because every “vibe coding” project quietly burns through a token budget — and most teams discover that only after the invoice. This app makes the budget visible before you start.
