MOJAQ vs Sentry: EU error tracking, honestly
Sentry is the deep, mature standard for error and performance monitoring, with an enormous ecosystem. MOJAQ takes a narrower position: a Sentry-SDK-compatible error tracker that keeps your data in the EU and sits in one account with analytics, flags, uptime, logs and deploys. Here is where each one is the right call.

Where Sentry is the better choice
If you live in performance data, Sentry is the deeper tool and it is not close. Transaction tracing, profiling, session replay and the sheer breadth of first-party integrations are years of focused work, and teams that depend on them should stay. Sentry also has the larger community, more framework-specific guidance and a mature alerting and workflow layer.
So if error and performance monitoring is a core discipline for you and you use Sentry's advanced surfaces daily, MOJAQ is not trying to out-feature it. Be honest about which of those surfaces you actually use before you consider moving.
Where MOJAQ fits better
MOJAQ wins on residency and consolidation. Stack traces are not innocent — they carry request URLs, user context and payload fragments, so where they are stored is part of your data-protection posture. MOJAQ keeps errors on dedicated infrastructure in Helsinki with a DPA and no US transfers in the storage path, which is exactly the point for an EU team that wants its telemetry to stay in the EU.
Because it is Sentry-SDK compatible, the switch is small: point your existing DSN at MOJAQ and keep your code. Sentry has added logs, uptime and cron monitoring of its own, so the deeper draw is breadth beyond observability: your errors sit in the same account as cookieless web analytics, feature flags, realtime and render, under one API key and one database. For an EU team that wants error tracking plus the rest of that stack in one place, without US data transfers, that combination is the draw — and it is free during the beta.
Switching from Sentry
Point your existing Sentry SDK at the MOJAQ DSN and deploy — no client rewrite. Send a test error, confirm the stack trace, breadcrumbs and grouping look right, and wire your release/deploy markers so errors correlate with ships. Run both in parallel briefly if you want a safety net, then retire the old project once you trust the new one. Historical events stay in Sentry unless you export them.
Questions
Do I have to change my code to move from Sentry?
No. MOJAQ exposes a Sentry-SDK-compatible DSN, so you keep your existing Sentry client libraries and just point the DSN at MOJAQ. That is the whole switch for the SDK side.
Where does Sentry win?
On depth and ecosystem. Sentry goes far further into performance monitoring, profiling, session replay and a huge integration catalogue. If you rely on those, Sentry is the more capable tool and you should keep it.
What is MOJAQ's advantage over Sentry?
EU-only data residency in Helsinki with a DPA, and a drop-in Sentry-compatible DSN so you keep your code. Sentry has grown its own logs, uptime and crons, so the real difference is breadth: MOJAQ also gives you cookieless analytics, feature flags and realtime in the same account, one API key and one database.
Is MOJAQ error tracking free right now?
Yes. Everything is free during the private beta, with no fixed end date and no card required. Paid plans will be announced in advance.
