FAQ
Questions about pricing.
How does the free tier handle large specs?
All processing is client-side. Specs with hundreds of endpoints process in under a second on modern hardware. Very large specs (5,000+ paths) may show a brief UI delay — the engine uses setTimeout chunking to avoid freezing the page.
What happens when the Pro tier says "comparison history"?
The comparison history is stored in your browser's local storage, not on a server. It persists between sessions on the same device. Each comparison's specs, labels, and result counts are saved so you can revisit a past comparison and restore the specs for re-analysis. Clearing your browser data removes it.
What do the "collapsible diff trees" do?
Breaking and additive changes are grouped by endpoint (e.g. GET /pets). You click an endpoint to expand its changes, then optionally toggle before/after detail blocks for each change. This lets you browse deep schema diffs without scrolling through every path at once.
When will the Pro tier actually take payment?
A Stripe payment processor is connected in test mode. The checkout form below accepts test card details (such as 4242 4242 4242 4242) and simulates a successful subscription without charging a real card. When the processor is switched to live mode, Pro subscriptions will process real payments. Until then, the checkout demonstrates the flow without charging real cards.
