How it works

Three steps to never being surprised

Works in minutes, runs in the background forever.

01
Connect your vendors
Paste a read-only API key. We encrypt it and pull your current usage in seconds.
02
We project 12 months out
Based on your growth rate, we calculate exactly when you'll hit each tier threshold.
03
Email 30 days before
You get a clear alert with the exact cost change, before it hits your credit card.

Features

Built for solo founders

Not another enterprise dashboard. This is the tool you actually needed.

Projections
12-month cost forecast
See exactly what your infra costs at 2×, 5×, 10× your current growth. Plan pricing before you need to.
Alerts
30-day tier warnings
Email alerts before you cross a pricing threshold — not after the invoice arrives. Configurable per vendor.
Security
AES-256 encrypted keys
Read-only access only. API keys are encrypted at rest. We pull usage counts — never your actual data.
Coverage
8 vendors, real pricing
Clerk, Vercel, Railway, Stripe, Resend, Supabase, PostHog, Sentry. Pricing verified and updated monthly.
