ErrorDock vs Sentry
ErrorDock combines error monitoring, performance and product analytics with per-feature health, one ranked list of priorities, feature flags and uptime monitoring, behind one project. Sentry approaches the problem from a different starting point; this page sets out where they differ, factually.
Overview
Sentry is an application monitoring platform focused on error tracking and performance monitoring. It is open source, widely adopted, and has SDKs for a large number of languages and frameworks.
Feature comparison
| Capability | ErrorDock | Sentry |
|---|---|---|
| Error monitoring | Implemented | Yes Sentry's core product. Source |
| Breadcrumbs | Implemented | Yes Source |
| Release tracking | Implemented | Yes Source |
| Regression detection | Implemented | Yes A resolved issue that reappears in a newer release is automatically marked Regressed. Source |
| Source maps | JS & Hermes | Yes Source maps are uploaded at build time, with Debug IDs injected into the build output. Source |
| Performance monitoring | JS SDKs + OpenTelemetry | Yes Sentry offers performance monitoring and tracing. Source |
| Distributed traces | OpenTelemetry (OTLP JSON) | Yes Distributed tracing across services. Source |
| Database performance | Spans only, no query view | Yes The Queries page reports throughput and duration per query, with the query's source in code on the SDKs that support it. Source |
| Product analytics | Implemented | — Not verified. Check current capabilities. Source |
| Feature analytics | Implemented | — Not verified. Source |
| Interaction tracking | Implemented | — Not verified. Source |
| Product Health | Feature health + priorities | — No equivalent concept to compare. ErrorDock's version is a per-feature health table and one ranked list of issues, latency regressions and underused features, which is a definition rather than a feature. Source |
| Impact-based priorities | Implemented | — No equivalent concept to compare. ErrorDock's version is a per-feature health table and one ranked list of issues, latency regressions and underused features, which is a definition rather than a feature. Source |
| AI root-cause analysis | Implemented | Yes Seer analyses the issue against the stack trace, tracing data, logs and the linked codebase to determine a root cause. Source |
| AI fix proposals and pull requests | Proposals; PRs off in beta | Yes Seer generates a code fix and can open a pull request. Unlike ErrorDock, it can be set to run automatically on issues that meet a threshold. Source |
| Feature flags | .NET SDK only | Partial Sentry ingests and correlates flag evaluations from providers such as LaunchDarkly, Statsig and Unleash. It does not serve flags to an SDK. Source |
| Uptime monitoring | HTTP, one EU location | Yes HTTP checks every minute, with a failure tolerance that defaults to three consecutive failures. Source |
| GitHub integration | Read-only | Yes Source |
| API access | Ingest + read-only API | Yes Documented web API with organization, internal-integration and personal tokens. Source |
Pricing philosophy
Sentry publishes tiered plans priced on event volume. Check their pricing page for current figures — we deliberately do not reproduce competitor prices here, because quoted numbers go stale and a stale price is worse than no price.
ErrorDock is preparing beta access. Paid subscriptions and automated billing are not available yet. Contact us to discuss access, usage and your stack.
ErrorDock pricingWhen Sentry is the better choice
Teams who want mature, broad error monitoring across many languages and are happy to run product analytics separately.
When ErrorDock is the better choice
When you need to know not just that something broke, but whether it matters. ErrorDock is the option if you want error monitoring, performance and product usage in one platform, with one connected workflow, and you want one ranked list of what to fix, weighted first by how many real users each issue affects and whether it came back.
