observability
Open source self-hosted observability platform that unifies session replays, logs, metrics, traces, and errors using ClickHouse and OpenTelemetry.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.
closest same-class full-stack alternative with session replay, error monitoring, logging, and tracing; choose if you want the same feature set with a different UI/community.
highlight.io: The open source, full-stack monitoring platform. Error monitoring, session replay, logging, distributed tracing, and more.
Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
uses an object-store/data-lake engine instead of ClickHouse and omits session replay; choose for very high-volume storage on S3-compatible backends.
Open source observability platform for logs, metrics, traces, frontend monitoring, pipelines and LLM observability. A sophisticated, simple and highly performant alternative to Datadog, Splunk, and Elasticsearch with 140x lower storage costs and single binary deployment.
S3-backed observability with natural-language LLM queries; choose when you want to query traces/logs/metrics conversationally rather than through a ClickHouse UI.
Monoscope lets you ingest and explore your logs, traces and metrics. We store these in S3 compatible buckets. Query in natural language via LLMs.
Go/MIT observability tool claiming a single root-cause view; choose if you want a lightweight Go-based alternative to the TypeScript/React HyperDX stack.
The only tool you need to know what is happening and how to fix it.
unified logs/metrics/traces platform built as a Rust data-lake engine; choose for a single native binary with S3/object storage instead of ClickHouse.
Parseable is an open source, unified infrastructure observability platform built in Rust on a data lake architecture. It tracks logs, metrics, traces, and events across apps, agents, and systems, reducing storage costs by up to 90% through columnar telemetry compression.
eBPF-based APM with AI root-cause analysis and no session replay; choose when you want zero-code instrumentation and service-map-centric troubleshooting.
Coroot is an open-source observability and APM tool with AI-powered Root Cause Analysis. It combines metrics, logs, traces, continuous profiling, and SLO-based alerting with predefined dashboards and inspections.
AI-native OpenTelemetry APM with multi-agent troubleshooting; choose if you want AI-driven RCA rather than session-replay correlation.
DataBuff is an AI-native APM built on Opentelemetry，with multi-agent troubleshooting out of the box.
An earlier or more limited way to do the job. Still the right call when you need something small, proven, or CPU-only.
backend ClickHouse/OTel APM for traces, metrics, and logs with no session replay; choose when frontend replay is unnecessary.
Open source APM: OpenTelemetry traces, metrics, and logs
popular OTel-native traces/logs/metrics platform without session replay; choose when you don't need replay and prefer SigNoz's community/ecosystem.
SigNoz is an open-source, OpenTelemetry-native observability platform for your team and their AI agents. Get logs, metrics, and traces in one tool with features like APM, distributed tracing, log management, infra monitoring, etc. Combined with SigNoz MCP and a native AI teammate (in SigNoz Cloud) it helps you build more resilient apps.
self-hosted session replay and product analytics, no backend trace/log/metrics engine; choose when frontend replay reproduction is your only need.
Session replay, cobrowsing and product analytics you can self-host. Best for reproducing issues and iterating on your product.
older distributed-tracing observability platform with no recent pushes; only for teams already committed to Hypertrace.
An open source distributed tracing & observability platform
These projects were analysed and named hyperdx among their alternatives. The relationship is not symmetric — how hyperdx rates them is a separate judgement, made when hyperdx is analysed in its own right.
