From gate to feedback to engagement
Access control
Magic-link authentication, one-click invites, instant revocation, and expiring access (24h / 7d / 30d / never). Strangers who land on the URL can request access from the no-access page — you approve or decline from the dashboard. Optional NDA gate when you need legal acceptance, off by default.
Engagement Pro
Per-reviewer top routes, daily timeline, and time on page. Session story narrates each visit in one paragraph. Every session is downloadable as CSV.
Reviewer feedback Pro
Signed-identity comments captured from inside the prototype, every one bound to a reviewer's invite. Auto-injected by the proxy on Pro, or drop in a one-line script tag.
Manage from your terminal or agent
CLI and MCP server cover projects, invites, audit, and engagement. Drops into Claude Code, Cursor, and any MCP-compatible agent. CLI and MCP docs.
Optional: origin secret middleware
Verify requests come from ProtoWall with one line of middleware. Works with any web framework. See agent-integration docs.
Versions and previews
Promote a new URL when you ship an iteration — engagement and feedback bucket per version automatically, with v1 / v2 history side-by-side. Plus per-PR / per-branch previews if you ship in pieces (Pro).
