Authentic Machine Gating & Product Utility Index
We don't trust marketing claims. We inject authentic payloads, measure real Time-to-Interactive (TTI), detect WebAssembly engines, verify zero-egress network privacy, and catch bait-and-switch login traps before users do.
⚡ The 5 Dimensions of Product Power
Every audited tool is evaluated from 0 to 100 on objective, reproducible browser-level metrics.
Sub-2s Time-To-Interactive (TTI), instant workspace readiness, and zero blocking overlay modals or cookie consent traps.
WebAssembly client compute acceleration, complex file parsing fidelity, and complete preservation of original dimensions and layers.
