# Feedback4.dev

> Feedback4.dev is a visual feedback platform for client websites. An authorized reviewer clicks an element and describes a change; the platform creates a structured ticket with page, selector, viewport, browser and bounded DOM context, then exposes it to a development team or an external AI automation through REST, durable HMAC-signed webhooks or a project-scoped MCP server.

Feedback4.dev solves the handoff between a client's visual request and the team or agent that owns the implementation. It adds reviewer verification, project boundaries, comments, traceability and client approval. It does not edit a repository, invoke an AI model or deploy a website.
