Catch every error before your users do.
jentry is hosted error tracking & performance monitoring for modern teams. Full stack traces, smart grouping, releases, crons and replays — so you fix issues before they hit production users.
No credit card · works with Sentry SDKs · send your first event in minutes
Features
Everything you need to debug production
A full monitoring stack, not just a crash log.
Error tracking & smart grouping
Capture exceptions with full stack traces, source-mapped frames, breadcrumbs and tags. Smart fingerprinting folds duplicates into one issue with a live event count.
APM — OpenTelemetry native
Point any OTel SDK or Collector at jentry (OTLP, protobuf or JSON) and get span-tree waterfalls, p50/p95, Apdex and automatic N+1 detection. Sentry SDKs work too.
Releases & suspect commits
See which release introduced an issue, track crash-free rates and adoption, and surface the commit most likely to blame.
Alerts & notifications
Get notified the moment a new issue appears, an error spikes, or a metric crosses a threshold — straight to email, with per-issue spike protection.
Replays, crons & profiling
Reproduce user sessions, monitor scheduled jobs for misses and timeouts, and profile transactions down to line-level timing.
Dashboards & Discover
Build custom widget dashboards and query raw events across every project with a powerful search syntax — is:unresolved level:error environment:production.
Workflow
From alert to root cause in one place
Every issue carries the full context you need to fix it.
See what broke
A grouped issue with the exception, the most-relevant stack frame expanded, breadcrumbs and the tags that matter — browser, OS, runtime, release.
Know who it hit
Event and user counts, a 24-hour and 30-day trend, first/last seen, and the tag distribution so you can tell a blip from an outage.
Find the cause
The suspect commit, the release that introduced it, and a slow-transaction view that points at the exact function spending the time.

Point your app at your jentry DSN — the same SDKs you already use.
Watch issues roll in
Errors, transactions and releases stream into a live dashboard.
The whole toolbox
One product, every signal
Errors are only the start. jentry ships the full monitoring surface you'd otherwise assemble from three or four tools.
Issues
Grouped errors with stack traces, breadcrumbs, tags and assignment.
Performance
Transactions, p50/p95, Apdex, trends and Web Vitals.
Insights
Queries, HTTP, caches and queues — grouped by span op, like Sentry Insights.
Traces
Distributed traces with a full span waterfall across services.
Session Replay
Reproduce exactly what the user saw when the error happened.
Release Health
Crash-free sessions, adoption and suspect commits per release.
Crons
Monitor scheduled jobs for missed or failed runs.
Uptime
HTTP checks with latency history and downtime alerts.
Dashboards & Discover
Custom widgets plus raw event search across every project.
Profiling
Line-level timing for your slowest transactions.
Metrics
Custom metrics with alerting on thresholds.
Code Coverage
Upload LCOV from CI and see coverage next to your stack traces.
Open standards
OpenTelemetry native. Sentry compatible.
No proprietary agent lock-in: send OTLP straight from any OpenTelemetry SDK or Collector, or keep the Sentry SDKs you already ship. Either way you get traces, spans and metrics in the same UI — and you can walk away with your instrumentation intact.

FAQ
Frequently asked
Which SDKs does jentry work with?
jentry speaks the Sentry SDK protocol, so any Sentry SDK works out of the box — point its DSN at jentry and your errors, transactions and releases stream straight in. OpenTelemetry SDKs and Collectors work too, via the native OTLP endpoint.
Do I have to change my code to switch from Sentry?
No. Keep your sentry-sdk / @sentry/node / @sentry/browser exactly as they are — only the DSN changes. Grouping, releases, environments and traces keep working.
How fast can I get started?
Create a free account, grab your DSN, drop it into your app, and you’ll see your first events in minutes. No infrastructure to set up.
Is my data secure?
Everything is encrypted in transit and at rest. We never sell or share your data, and you can delete a project and its events at any time.
Can I migrate from Sentry?
Yes — point your existing Sentry SDKs at jentry and import your projects, so you can switch over without changing your app code.
How much does it cost?
Free to start, with paid plans at a flat, predictable price: Team at $14/mo and Business at $49/mo. No per-seat pricing and no surprise overage bills.
