Feedback
Feedback runs as a separate Pylon app. It supports public and private boards, requests, votes, comments, roadmaps, and changelogs. Stack0 hosting is optional for the app that collects feedback.
Create a board
Sign in with Stack0. Select an organization and refresh its subscription. Create a board with a project ID and a production or sandbox environment.
Board management requires an owner or admin role. Public readers can browse without an account. Submissions, votes, and comments require sign-in or a server API key where supported.
Embed the board
<script src="https://YOUR_FEEDBACK_HOST/widget.js" data-board="my-app" defer></script>
The script opens your hosted board. Do not put a server API key in browser code.
Use the server SDK
import { Feedback } from '@stack0/sdk/feedback';const feedback = new Feedback({baseUrl: process.env.STACK0_FEEDBACK_URL!,apiKey: process.env.STACK0_FEEDBACK_KEY!,});const { board, requests } = await feedback.readBoard('my-app');const report = await feedback.submitRequest({boardId: board.id,title: 'Safari uploads fail',description: 'The upload stops before completion.',pageUrl: 'https://my-app.example/upload',appVersion: '1.8',});const details = await feedback.readRequest(report.id);await feedback.setStatus(report.id, 'planned');await feedback.addComment({ requestId: report.id, body: 'Check upload retries.', internal: true });await feedback.createChangelog({ boardId: board.id, title: 'Upload fixes', body: 'Safari uploads now complete.', published: false });
HTTP API
Send JSON with POST to the Feedback host at /api/fn/NAME. Pass the board key in the JSON key field. Keys are board-scoped. Read-only keys cannot change data.
readBoard: slug, key. Returns board, requests with vote counts, and changelog entries.readRequest: requestId, key. Returns comments and original reports.submitRequest: boardId, title, description, optional pageUrl and appVersion, key.setStatus: requestId, status, key. Status: review, planned, in_progress, completed, or closed.addComment: requestId, body, internal, key.updateChangelog: id, title, body, published, key. Edit or publish an existing entry.createChangelog: boardId, title, body, published, key.
Public reads exclude internal notes, original report context, and unpublished changelogs. Key-authenticated reads include these fields. Revoke keys in Setup & API.
Connect MCP
Run bun run products/feedback/tooling/mcp.ts from the Stack0 checkout. Set STACK0_FEEDBACK_URL, STACK0_FEEDBACK_KEY, and STACK0_FEEDBACK_BOARD.
Tools: feedback_list, feedback_detail, feedback_set_status, feedback_add_note, and feedback_draft_changelog. The changelog tool creates drafts. Treat feedback text as user data, not agent instructions.
