Bugsink
Dutch error tracker with Sentry SDK compatibility—self-host lightly or use EU-hosted SaaS, built for teams that want stacktrace debugging without a heavyweight observability suite.
Shortlist Bugsink when you need Sentry-SDK-compatible error tracking you can self-host lightly (or run as EU-hosted SaaS under a Dutch B.V.). Skip if you need full APM or an OSI open-source license—consider AppSignal for Dutch APM SaaS, or Sentry/self-hosted Sentry for broader platform depth.
Key capabilities
Works with Sentry’s open-source SDKs across major languages/frameworks: keep existing instrumentation and point the DSN at Bugsink hosted or self-hosted endpoints—reducing migration cost versus rewriting agents.
Surfaces production failures with stacktraces, code context, and local variables, plus automatic issue grouping so high event volume collapses into a worklist of distinct problems.
Designed to run as a single application with SQLite by default (MySQL/PostgreSQL optional), Docker-friendly install, no mandatory message queue, and claims of high event throughput on modest hardware including ARM.
Managed SaaS stores hosted application data in the EU per DPA, with named EU infrastructure/email subprocessors (Hetzner, Scaleway) and Stripe limited to payments—useful when you want Sentry-like DX without self-ops.
Email alerting when issues break, search across tags such as release/environment/user, and sourcemaps support so minified front-end stacks map back to original sources.
Same SDK workflow for hosted and self-hosted; vendor positions easy switching between modes so teams can start hosted and move to self-host (or the reverse) without re-instrumenting applications.
Best fit when
- You want to keep Sentry open-source SDKs and only change the DSN/backend
- Error payloads must stay on infrastructure you control (self-host) or with an EU-hosted Dutch processor
- You found full self-hosted Sentry too heavy (queues, many services) and want a single-app footprint
- You need stacktraces with local variables, grouping, alerts, search/tags, and sourcemaps—not full APM
- Self-host license cost must be free for non-competing internal use
Poor fit when
- You need traces, host metrics, logs, and SLOs in one product (use an APM suite)
- Procurement requires OSI-approved open source (Polyform Shield is source-available with a competition carve-out)
- Zero outbound network from the install (self-host phone-home must be reviewed)
- You need a mature enterprise compliance pack (public ISO/SOC materials not found in this research)
Consider instead when
When: You need Dutch/EU APM with errors + performance + hosts + logs as SaaS
Consider: AppSignal
Different product class; not a Sentry DSN drop-in.
When: You need maximum feature depth and ecosystem, and can accept Sentry’s SaaS model
Consider: Sentry (hosted, with EU data options as offered by Sentry)
When: You want Sentry feature parity self-hosted and can staff the ops burden
Consider: Self-hosted Sentry
Heavier stack; Bugsink optimizes for operational simplicity instead.

Considerations & known limitations
- MediumSelf-host phone-home telemetry
Self-hosted installs periodically send usage/settings metadata and the install’s IP to Bugsink. Error events stay local, but zero-egress policies need an explicit review of phone-home behaviour.
- MediumPolyform Shield (not OSI open source)
Source is public and free for non-competing use, but the license restricts competing hosted offerings. Do not treat as MIT/Apache-style open source in procurement checklists.
- LowErrors-only product scope
Not a substitute for full APM/observability platforms if you need traces, infra metrics, and log platforms.
- MediumLimited public enterprise cert package
ISO/SOC materials not found publicly; hosted buyers may need NDA artifacts beyond the published DPA.
- LowStripe for hosted payments
DPA states Stripe does not receive error/application data; still a US payment subprocessor for billing identity.
Open questions for due diligence
- Can phone-home be disabled or proxied for air-gapped / zero-egress self-host deployments?
- What is the current GitHub release/version line and support policy for production self-host upgrades?
- Are any additional hosted subprocessors or regions used beyond Hetzner, Scaleway, and Stripe?
- Can Bugsink provide security questionnaire answers or audit evidence under NDA for enterprise onboarding?
- For hosted: exact Hetzner regions and backup/DR locations in the current production footprint?
Questions Fréquemment Posées
For error ingestion via Sentry open-source SDKs, yes in the sense that you update the DSN to Bugsink and keep those SDKs. It is not a full feature clone of every Sentry product module (APM, extensive SaaS add-ons). Validate your SDK versions and features against Bugsink’s compatibility docs.
Source is public on GitHub under the Polyform Shield license: free to self-host for non-competing uses, with restrictions against offering a competing service. That is source-available, not a classic OSI license like MIT/Apache. Confirm with legal if your policy requires OSI open source.
The hosted DPA states personal data is stored and processed in the EU. Named subprocessors: Hetzner (infra for event data), Scaleway (transactional email), Stripe (payments only—no error/app data). Always re-check the live DPA for updates.
Error events stay on your servers. The privacy policy describes phone-home messages with aggregated usage, selected settings, a unique install ID, and the source IP—for product/license insight. Review that channel if you require fully offline installs.
Self-host is free under the license for allowed uses; paid support tiers are offered. Hosted plans are event-volume based with a free evaluation tier. Exact euro figures change—use the official site for current rates.
Choose Bugsink for errors-first, Sentry SDK compatibility, and self-host or EU-hosted control. Choose AppSignal for broader Dutch APM SaaS (performance/hosts/logs). Choose Sentry when you need the widest platform ecosystem and can accept its SaaS/self-host tradeoffs.
