For developers who ship seriously

Turn every client comment into work you can close.

Feedback4.dev is a visual feedback widget you install on client websites. Clients click any element and describe a change; your team receives a structured ticket with the selector, page, viewport and an approval workflow.

Feedback4.dev captures the exact element, technical context and client decision in a ticket your team can act on.

A better handoff for every release

Your client does not need to learn your stack. Your team needs context.

Leave coordinate-less screenshots and email threads behind. Every ticket keeps where it happened, what was requested and who can approve it.

A signal, not an interpretation

Clients point at the exact element on your site. Store selector, URL, viewport, browser and DOM context.

A ticket with memory

Conversation, attachments, status, priority and owner live together. Your team stops reconstructing the story.

Delivery with control

You can send changes to review and record approval. Authorized clients and revocable credentials stay server-side.

From comment to closed ticket

Make the review part of your delivery system.

01

Capture

The client points at the problem in the real interface, without writing a technical brief.

02

Decide

Your team receives evidence, assigns the ticket and returns a traceable decision.

03

Ship

Implement with context, request approval and close with a story everyone understands.

Fits the way you build

A handoff your code can understand.

Connect REST or MCP to your internal tools. The ticket arrives with structure, scope and status—not a screenshot lost in Slack.

Control you can see

Serious about access. Simple for your client.

  • Verified client sessions
  • HMAC-signed webhooks
FAQ

Questions that show up before launch

How does my client start sending feedback?

Install the widget and authorize their emails. The client verifies access by email before sending a ticket; an arbitrary visitor cannot open it.

Can I connect it to my own dashboard?

Yes. The REST API exposes projects, tickets, reviewers, approvals and webhooks. The docs include payloads, scopes, errors and runnable examples.

What is included in Pro?

Pro is $4 USD per month, billed annually at $48 USD. It includes the multi-project workflow, agent integrations, approvals, signed webhooks and access controls.
