ProtoWall Is Live

2026-04-21 · ProtoWall Team

ProtoWall is live. We launched on Hacker News and Product Hunt.

What it does

ProtoWall is a review platform for confidential prototypes. You invite reviewers by email, they authenticate, and they access your prototype through a reverse proxy. You see exactly what they engaged with — top routes, time on page, session-by-session event log, signed-identity feedback. Your app doesn't change. No SDK, no middleware, no code changes.

An optional NDA gate is available per project, off by default. Turn it on when you need legal acceptance and reviewers sign a versioned document on the way in. Every action is audit-logged either way: timestamps, IPs, user agents, signature names, SHA-256 content hashes. You can export the full trail as CSV or download a per-reviewer PDF evidence package. If someone leaks your work, you have documented proof of access — and, if the gate was on, of agreement.

Why we built it

We kept hitting the same problem. We'd build a prototype, need to show it to someone, and have no good way to share it without just handing out a URL.

Password protection is weak. Passwords get shared, and you have no record of who accessed what. Screen-share calls don't scale. Private beta tools skip the legal side. And "just trust them" isn't a strategy.

We wanted something that handles authentication, legal acceptance, and access control in one flow. And we didn't want to modify every prototype to support it.

How it works

Two services: a web app that handles users, invites, and NDA signing, and a reverse proxy that validates sessions and forwards traffic to your prototype.

Auth is magic-link only. No passwords for anyone. Reviewers click a link in their email and they're in — accepting the NDA on the way if the project has the gate enabled. The proxy creates a 30-day session cookie.

NDAs are versioned when the gate is on. Publish a new version and existing reviewers lose access until they re-sign. Each consent is tied to a specific document version.

Revocation is instant. Click Revoke, and the session is deleted. Not invalidated at the next token refresh. Deleted.

Pricing

Free tier gets you 1 project and 5 invites. Enough to run a real pilot.

Pro is $19/month for 5 projects, 25 invites per project, custom NDA text, full version history, 90-day audit retention, and PDF evidence export.

If you're coming from Product Hunt, use code PRODUCTHUNT for a free month of Pro.

What's next

We're listening to what the first users actually want and shipping accordingly — reviewer engagement analytics, AI session summaries, project versions, project previews, and a CLI + MCP server have all landed since launch. If you try it and have feedback, we want to hear it — [email protected].
