Sentry and SnagRelay solve different halves of the same problem. Sentry watches your code for errors and links user feedback to the errors and replays it already has. SnagRelay is built around the report a person files: the element they pointed at, the requests and console from that page, and the loop back to them when it is fixed. You can run both.
What Sentry's User Feedback does
Sentry has a User Feedback widget and a Crash-Report modal. According to Sentry's documentation, feedback can include the user's description, a screenshot, their email, an associated replay (up to 60 seconds before they submitted), the page URL and tags, and it is linked to the errors Sentry captured. From the feedback page you can resolve it, assign it, and create or link a GitHub or Jira issue.
Where Sentry is the better choice
- Errors and performance. Sentry detects exceptions, groups them into issues and alerts you, whether or not a user complained.
- Feedback tied to an error. When the user hits a crash, the feedback attaches to that error and its stack trace automatically.
- Triage tools. AI summaries of feedback, spam detection and alert rules.
- An MCP server for working with issues from your agent.
Where SnagRelay is different
Many bugs throw no error
A wrong total, a missing row or a button that does nothing often has no exception to link to. SnagRelay's report carries the requests from the page, with request and response bodies for failed and successful calls, so a 200 with the wrong data is visible. Your agent pulls any one with get_issue_payload.
The reporter points at the element
The reporter clicks what is wrong. The report records its label, component and selector and outlines in red the elements tied to an error or a failed request. See the element picker.
A report built for the person who fixes it
Repro steps from the session, the replay, the console and the element arrive together, and get_issue_context returns them to Cursor, Claude Code or Codex by key. See the MCP server.
The reporter hears back
When the agent calls mark_issue_resolved, the person who reported the bug gets a "fixed" email. get_related_history gives the agent earlier bugs like this one and what fixed them. See related reports and history.
Setup is one script tag
SnagRelay needs no error-monitoring SDK to produce a useful report. Reports go to an inbox, or to Jira Cloud, Linear, GitHub, GitLab.com, Trello or Azure DevOps Services.
Side by side
| SnagRelay | Sentry | |
|---|---|---|
| Main job | Bug reports from people using your site or app | Error and performance monitoring, with a feedback widget |
| Finds bugs nobody reported | No | Yes, that is its core |
| Reporter points at an element | Yes | Feedback is a description, with an optional screenshot |
| Request and response bodies in the report | Yes, failed and successful | Depends on your Sentry setup |
| Session replay with the report | Yes, length depends on plan | Yes, up to 60 seconds before submission |
| MCP server | Reports, payloads, related history, resolve | Issues and analysis |
| Reporter gets a "fixed" email | Yes | Not in the documented feedback features |
| Pricing | Per project, never per reporter | See Sentry pricing |
Using both
Keep Sentry for what your code throws, and use SnagRelay for what people tell you. When your agent has both, it can read the SnagRelay report by key and look up the matching Sentry issue in the same session.
Who should choose which
Choose SnagRelay if your bugs arrive from testers, clients or customers and you want each one to carry the element, the requests and the steps. Choose Sentry if you need to find errors before users do. Most teams that ship with an agent want both.
