ProofBench
Publishes test landing pages and tracks buy-intent to validate startup ideas
ProofBench spins up a landing page for each startup idea, tracks signups and buy-button clicks, and ranks ideas by intent rate — buy-clicks divided by views — rather than raw traffic, so a page with 80 views and 40% intent beats one with 2,100 views and 9%. It's also an MCP server: connect Claude Code or Cursor and your agent builds, publishes, and reads back the page's signal, though it can't publish on a free account, touch another maker's bench, or delete anything. Designing and configuring pages is free; going live costs a one-time $29 for a year or $49 for a lifetime pass — no subscription.
What holds up
- +Ranks by buy-intent rate, not raw views — a page with 40% intent beats one with 10x more visitors
- +One-time $29 to go live for a year, or $49 lifetime — no subscription
- +MCP server lets Claude Code or Cursor build, publish, and read an idea's signal without leaving the editor
- +Design and configure test pages for free — you only pay once you actually deploy
Mind the limits
- −Your agent can't publish on a free account or delete anything — some steps still need a human and payment
- −Measures buy-button clicks, not completed payments — intent still isn't a paying customer
