Share prototypes.
Protect your work.

ProtoWall puts an authentication and legal-agreement wall in front of your prototypes. Invite specific people, require NDA acceptance, and proxy traffic — without changing your app.

Everything you need to share confidential work

Reverse proxy

Your prototype stays on your infrastructure, unchanged. ProtoWall proxies authenticated traffic to it — no SDK, no code changes.

Versioned NDAs

Each project gets a legally binding NDA. Update the text any time — existing reviewers must re-accept before regaining access.

Magic-link authentication

No passwords to manage or leak. Reviewers log in via email, accept the agreement, and access the prototype in one flow.

Audit trail

Every action logged with timestamp, IP, and user agent. Know exactly who accepted what, when, and from where.

Instant revocation

Revoke access with one click. Sessions are terminated immediately — no waiting for token expiry.

Origin secret verification

Each project gets a unique secret header. Add one line of middleware to your app to reject any traffic that doesn't come through ProtoWall.
