Pricing
Everything is free while Topkay is in preview. The local MCP and CLI stay free to run on your own machine, always. When preview ends the deterministic tools stay free and the model-powered tools become a paid tier, priced on usage not seats.
Free tools, no account
The one-shot checks that run in the browser: the audit, see as bot, AI access, response headers, schema check, sitemap, agent readiness and origin surface. Run them here, or run the whole suite locally with npx topkay and send nothing anywhere.
Free account
A free account adds the model-powered tools and your site twin. Verify your domain and Topkay crawls your whole site once, holds it as one graph every tool reads, and gives you Ask Topkay, the analyst that reasons over it and cites it.
Paid tier, when preview ends
The split is honest. Anything Topkay computes deterministically, fetch, parse, render, diff, stays free. The tools that call a model on our dime, the answerability judge, the embeddings and the model-by-model checks, cost us on every run, so those become the paid tier when preview ends. No opaque credits. We will publish the numbers before we charge, so you see the cost before you wire a tool into your workflow.
