SaaS tools advertise one price and charge another. We manually research every hidden fee, overage rule, and forced upgrade — so you know the true cost before you sign up.
No signup required. Free forever. Based on real pricing data, not estimates.

Review sites are vendor-funded. G2's paying customers ARE the SaaS vendors. They literally cannot expose hidden costs — it would destroy their business model. We have zero vendor relationships.
Search "why is Zapier so expensive" — a 2023 Reddit thread ranks #1. 1,300 people search this every month and find outdated, anecdotal answers. We built the definitive resource.
Search "Zapier cost calculator" — 880 people/month find nothing but Zapier's own static pricing page. No interactive calculator exists. We're the first and only one.
SaaS companies engineer pricing tiers so you'll hit the limit and get auto-upgraded. Zapier's 750 tasks/mo limit is designed to push you to the $103/mo Team plan. We expose this.
Not AI-generated guesses. Our team reads pricing pages, terms of service, Reddit threads, support docs, and GetApp reviews for each tool. We document every overage rule, forced upgrade trigger, and surprise charge.
Tasks per month, team size, storage needs, premium apps — the numbers that actually drive your bill. Not the default 'starter' usage the pricing page assumes.
Line-by-line breakdown: base price, per-seat costs, overage charges, hidden fees. Plus a confidence score showing how reliable our estimate is. And cheaper alternatives with savings %.
