We build Interfere, so take this comparison with that in mind. We’ve aimed to be fair, and every claim about Sentry links to Sentry’s documentation.
Here’s the honest summary. Sentry is one of the broadest error monitoring tools you can buy. It has SDKs for 22 platforms, from React to Unity, plus tracing, profiling, cron jobs and uptime checks. If you need all of that in one place, it’s hard to beat.
Interfere is narrower on purpose. We focus on web apps and the OpenTelemetry services behind them. Instead of a feed of errors, you get problems: each one ranked by who it affects, explained with evidence, and tied to the release that caused it. Then your team, or any coding agent you already use, fixes it.
The short version
| Sentry is the better fit if you… | Interfere is the better fit if you… |
|---|---|
| Ship mobile apps, or backends in many languages | Build a web app on Next.js, React, Vite or TanStack Start |
| Need profiling, cron monitoring or uptime checks | Want bugs triaged for you, with the root cause and the users they affect |
| Want to self-host, or must keep your data in the EU | Want to fix bugs with your own coding agent, through MCP |
| Rely on a long list of integrations | Send traces, logs and metrics over OpenTelemetry |
Feature by feature
| Capability | Sentry | Interfere |
|---|---|---|
| Error tracking | SDKs for 22 platforms; events grouped into issues | SDKs for Next.js, React, Vite and TanStack Start; errors grouped into problems |
| Root cause | Seer Autofix works out a root cause and a solution | Findings on every problem, linked to the release, pull request and commit |
| Fixes | Autofix can open a pull request; follow-ups and agent handoff need GitHub | A suggested fix on each problem; any agent that supports MCP can open the pull request |
| After the fix | Release health, and issues resolved in a release | Tracks recovery until the bug stops, and reopens it as a regression if it comes back |
| Session replay | Web and mobile | Browser, with masking and consent controls |
| OpenTelemetry | Traces and logs over OTLP, in open beta; no OTLP metrics | Traces, logs and metrics over OTLP/HTTP |
| Vercel | Log and trace drains | Trace and log drains, created for you when you connect Vercel |
| AI agents | Sentry MCP server | MCP server (read-write or read-only), CLI, and plugins for Claude Code and Cursor |
| Profiling | Continuous and UI profiling | No |
| Crons and uptime | Yes | No |
| Mobile apps | Android, iOS, React Native, Flutter and more | No |
| Self-hosting | Yes, under the FSL license, without Seer or other AI features | No, hosted only |
| Data residency | US or EU, picked when you create your organization | Not yet |
Where we think Interfere is different
You get problems, not just errors. Sentry is very good at catching and grouping events. We think the harder part starts after that: which group matters, why it happened, and whether the fix worked. Interfere ranks each problem by the users and companies it affects, lays out the likely cause with the evidence behind it, and points at the release that introduced it. Once a fix ships, it watches until the bug actually stops, and reopens it if it comes back.
You choose who writes the fix. Seer is Sentry’s own agent, built into Sentry. We went the other way. Interfere suggests a fix, and also hands the full investigation to any coding agent through MCP. The pull request can come from Claude Code, Cursor, Codex, Grok Bot or one of your engineers. Our Grok Bot guide shows one way to run that on a schedule.
OpenTelemetry is a first-class input. You can send us OTLP traces, logs and metrics today, and our Next.js SDK works with @vercel/otel instead of replacing it. Sentry accepts OTLP traces and logs in open beta. If OTel is how your team instruments things, our @vercel/otel guide walks through the setup.
When we’d tell you to pick Sentry
Pick Sentry if you ship native mobile apps, run backends in languages you haven’t moved to OpenTelemetry, want profiling or cron and uptime monitoring in the same tool, need to self-host, or have to keep data in the EU. Sentry has also been around much longer, and its integration catalog is bigger than ours. Those are real advantages, and we’d rather you know them up front.
Trying Interfere without leaving Sentry
You don’t have to switch in one go. You can run both for a while:
- Add the Interfere SDK next to Sentry’s. Follow the Next.js or Vite guide.
- Keep source maps for both tools. If another uploader runs after ours, set
sourceMaps: { purge: false }inwithInterfere()so we leave the maps in place. The releases docs explain the order. - Let one SDK handle trace headers. If two browser SDKs both add
traceparentto the same request, browser-to-server traces break. Point the other SDK’s trace propagation at different hosts. - Compare them on real bugs for a week or two, and remove Sentry’s SDK when you’re ready.
One thing to know: Interfere doesn’t import your Sentry history. Problems start from the first events we receive.
Set up Interfere and try it on your own app.
