Hey Product Hunt! I'm Roberto, co-founder of ProtoWall. We kept running into the same problem: needing to share a working prototype with an investor or client, but not wanting to just hand out an unprotected URL. Building custom auth + NDA flows for every prototype felt like overkill. ProtoWall sits as a reverse proxy in front of your app. You invite people by email, they accept a versioned NDA, and get proxied through to your prototype. If you update the NDA text, they have to re-accept. Everything is audit-logged: timestamps, IPs, user agents, signatures. You can export a CSV trail or download per-reviewer PDF evidence packages if you ever need to prove someone agreed to your terms. Free tier gets you 1 project and 5 invites. Pro ($19/mo) adds custom NDAs, PDF evidence export, and up to 5 projects. Would love your feedback; especially on what features you'd want to see next!
