ProtoWall sits as a reverse proxy in front of your app. You invite reviewers by email, they click a link, read and sign a versioned NDA, and then get proxied through to your prototype. No SDK, no code changes on your end.
How it works:
- You add your prototype's origin URL and configure an NDA - Invite specific people by email; they get a one-click link - Reviewer accepts the NDA (name, timestamp, IP, user agent all recorded) - A 30-day proxy session is created; traffic flows through to your app - You can revoke access instantly; the session terminates immediately, not at the next token refresh
Every action is audit-logged. You can export a CSV of the full trail or download a per-reviewer PDF evidence package with consent records, NDA text, and SHA-256 content hashes; useful if you ever need to prove someone agreed to your terms.
Auth is magic-link only (no passwords to manage or leak). NDAs are versioned; if you update the text, existing reviewers must re-accept before they can access again.
Free tier: 1 project, 5 invites. Pro is $19/mo for 5 projects and PDF evidence export.
Happy to answer questions about the architecture or the legal side of things.
