HyperDX and Oh Dear both fall under the broad umbrella of monitoring, but they watch very different things: HyperDX is a full-stack observability platform…
Best for HyperDX: Engineering teams needing unified logs, traces, metrics, and session replay for their own applications, especially those instrumenting with OpenTelemetry and wanting a ClickHouse-backed, usage-priced observability stack.
Best for Oh Dear: Agencies and site owners who need external uptime, SSL, DNS, cron, and performance monitoring with client-facing branded status pages and every feature included on every plan.

Key Differences
Monitoring Scope
HyperDX: HyperDX provides full-stack observability covering logs, traces, metrics, errors, and correlated session replay via OpenTelemetry instrumentation.
Oh Dear: Oh Dear provides external website health checks — uptime, SSL certificate monitoring, DNS/domain expiration, broken link and mixed content scanning, cron job monitoring, and Lighthouse-based performance monitoring.
This determines whether you need deep in-app telemetry (HyperDX) or black-box external website monitoring (Oh Dear).
Pricing Structure
HyperDX: HyperDX is usage-based on storage volume, with a free 3GB/month tier and a $20/month Starter plan (50GB, unlimited users, $0.40/GB overage).
Oh Dear: Oh Dear has no permanent free tier (only a 10-day trial) and prices by number of monitored sites, from €13/month (Mini, 5 sites) up to €201/month (Premium, 200 sites), with every feature included at every tier.
HyperDX cost scales with data volume while Oh Dear cost scales with number of sites/servers monitored — different budgeting models.
Client/Agency Reporting Features
HyperDX: No client-facing status page or agency reporting feature is documented for HyperDX.
Oh Dear: Oh Dear offers branded client status pages with automated monthly reporting, explicitly suited to agencies.
Agencies managing multiple client websites need white-labeled reporting, which is a named Oh Dear feature.
Session Replay & Distributed Tracing
HyperDX: HyperDX offers correlated session replay linking user recordings with backend logs/traces, plus end-to-end tracing across browser or mobile apps through backend services.
Oh Dear: No session replay or distributed tracing feature is documented for Oh Dear.
Debugging user-reported bugs benefits from correlated replay and traces, a capability specific to application observability tools.
Compliance & Hosting Region
HyperDX: HyperDX is SOC 2 Type II certified, with SAML SSO available on the custom-priced Enterprise plan.
Oh Dear: Oh Dear is EU-hosted with GDPR-friendly terms and a Data Processing Agreement (DPA) available; SOC 2 is not mentioned.
Compliance requirements differ by region and industry — SOC 2 matters for US enterprise buyers, while EU hosting and a DPA matter for GDPR-sensitive customers.

Pricing Compared
Starting price reflects the lowest paid tier, not the full cost for every team size or usage level.
Fully open source and self-hostable under MIT and Apache 2.0 licenses
ClickHouse backend delivers fast queries even at very large log and trace volumes
Usage-based pricing avoids expensive per-seat or per-host costs common at competitors
Unifies logs, traces, metrics, and session replay in one interface instead of separate tools
Backed by ClickHouse Inc.'s engineering resources following the 2025 acquisition
Cons
Newer platform with a smaller overall feature set than mature vendors like Datadog or New Relic
Self-hosting requires operating and maintaining a ClickHouse cluster
Free tier retention is limited to just 3 days, which may be too short for some teams
Documentation and ecosystem are still maturing following the ClickHouse acquisition
Fewer pre-built third-party integrations than long-established observability vendors
Oh Dear
Pros
Every plan includes the full feature set, no functionality is gated behind higher tiers
Combines uptime, SSL, performance, DNS, and cron monitoring in one dashboard instead of several tools
Built and actively maintained by two well-known developers in the Laravel and PHP community
Transparent, predictable pricing based purely on number of sites monitored
10-day free trial with no credit card required, plus a 30-day money-back guarantee
Cons
Pricing is per site or server, so monitoring many small sites can get expensive compared to unlimited-site competitors
Smaller company than large monitoring vendors, so integration breadth may be narrower
No free tier, unlike some competitors offering a limited always-free plan
Primarily English-language interface and support
Focused on website and infrastructure monitoring rather than full application performance monitoring (APM) depth
Use Cases
Choose HyperDX: Engineering teams needing unified logs, traces, metrics, and session replay for their own applications, especially those instrumenting with OpenTelemetry and wanting a ClickHouse-backed, usage-priced observability stack.
Choose Oh Dear: Agencies and site owners who need external uptime, SSL, DNS, cron, and performance monitoring with client-facing branded status pages and every feature included on every plan.
Need both: A development agency could use Oh Dear to monitor uptime, SSL, and cron health across client websites for branded status-page reporting, while using HyperDX internally to trace and debug errors within their own application backends — complementary tools addressing different monitoring layers.
HyperDX
Debugging Production Incidents — Correlate logs, traces, and session replay in one place to quickly find the root cause of an outage.
Self-Hosted Observability on Existing Infrastructure — Run observability entirely on a team's own ClickHouse cluster for cost and data control.
Cost-Sensitive Observability at Scale — Monitor growing data volumes without per-host or per-seat pricing eating into infrastructure budgets.
Oh Dear
Freelance developer client monitoring — Freelancers monitor uptime, SSL, and performance across several client sites from one dashboard on the Freelance plan.
Agency-wide site health monitoring — Digital agencies use Oh Dear's Agency and Portfolio tiers to track uptime, broken links, and performance across dozens of client websites.
SaaS infrastructure and cron monitoring — SaaS teams monitor application uptime alongside scheduled background jobs to catch failures that a simple uptime check would miss.
