OpenObserve
open sourceAGPL-3.0Self-host
22.9knov 2026
Monitor logs, metrics, and traces with an open-source observability platform. Achieve petabyte scale with 140x lower storage costs and high performance.
The catch vs LogicMonitor
It can ingest and search logs cheaply, but you must operate storage and collectors and give up Axiom's managed serverless scaling and polished event-query experience.
Install, platforms & data +
platforms
webself-hosteddocker to self-host
install
Hosted signup, or a single binary/Docker container; Helm plus external services for HA
setup
The easy single-node path still needs collectors and persistent storage; production HA adds Kubernetes, object storage, PostgreSQL, and NATS.
your data
Telemetry is stored as Apache Parquet on local disk or object storage; single-node metadata defaults to SQLite, while HA uses PostgreSQL and NATS.

Coroot
open sourceApache-2.0Self-host
8knov 2026
Coroot simplifies system monitoring by providing metrics, logs, traces, and profiling with zero instrumentation, leveraging eBPF technology.
The catch vs LogicMonitor
It is strongest for Linux containers and Kubernetes, but lacks Datadog's breadth across integrations, synthetics, RUM, security, cloud services, and managed global operation.
Install, platforms & data +
platforms
webself-hostedself-host, real ops
install
Docker Compose for one host, or the Kubernetes Operator/Helm for a cluster
setup
The eBPF node agent needs a supported Linux kernel and privileged host access on every node, and the product is most natural for containers and Kubernetes.
engines
Core observability is non-AI; optional root-cause investigations connect to Coroot Cloud or configured Anthropic, OpenAI, Azure OpenAI, Groq, Mistral, Ollama, or OpenAI-compatible endpoints.
your data
Metrics use Prometheus-compatible storage or ClickHouse, while logs, traces, and profiles use ClickHouse; configuration uses SQLite by default or PostgreSQL.
