A Marker.io alternative built around your coding agent.
Marker.io manages feedback. Pincushion helps coding agents implement it. Pins carry selector, DOM snippet, screenshot, viewport, thread, and project context in one MCP call — so Cursor, Claude Code, and Codex land the change in your IDE, not a Kanban column.
What Pincushion is built for
Pincushion is the implementation context layer for AI-native development. The data model treats a pin as an agent work packet — not a feedback item — so the gap between "stakeholder pointed at a button" and "code change shipped in your IDE" collapses to one MCP call.
- AI-native builders shipping with Cursor, Claude Code, Codex, or Copilot
- Small web agencies who want clients to drop pins their agent can act on (fewer revision calls)
- Small product teams who want UI feedback before it becomes a bloated ticket
How Pincushion differs
| Pincushion | Marker.io | |
|---|---|---|
| Pin payload designed as agent work packet (selector + DOM + screenshot + viewport + thread + acceptance criteria) | Yes | Feedback metadata |
| Center of gravity | IDE (slash commands, branch/PR/deploy linkage) | Dashboard + Jira sync |
| Free unlimited stakeholder/commenter seats | Yes | Per-user pricing |
| Realtime push to coding agents on deploy | Yes (Pro) | No |
| IDE slash commands (claim / implement / resolve) | Yes (Cursor, Claude Code, Codex, Windsurf) | No |
| Post-deploy verification (AI verifies the fix) | Yes (Pro) | No |
| Skips Jira / project-management ceremony by design | Yes | Jira-integrated |
| Free tier | Full workflow, 1 project, unlimited pins | 14-day trial |
| Starting price | $19/mo (Pro) | $39+/mo |
Other tools hand feedback to developers. Pincushion hands it to your coding agent — selector, DOM, screenshot, viewport, thread, and project context, all in one MCP call.
Stop turning feedback into tickets. Turn it into agent-ready code work.
Pincushion is free for stakeholders forever. Editors get an MCP server that exposes pins to whichever coding agent you already use. The deploy hook auto-resolves pins on production and the MCP tools keep PR and deploy context attached to the pin's implementation record.
