8knov 2026
Coroot simplifies system monitoring by providing metrics, logs, traces, and profiling with zero instrumentation, leveraging eBPF technology.
The catch vs AppDynamics
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.

4.3knov 2026
Uptrace is an OpenTelemetry-based platform that integrates traces, metrics, and logs to help monitor and optimize complex distributed systems.
The catch vs AppDynamics
It is a capable OpenTelemetry APM, but it is narrower than the hosted Grafana, Prometheus, Loki, and Tempo ecosystem and carries a multi-database self-hosting burden.
Install, platforms & data +
platforms

setup
Even the small-team Compose deployment is a multi-database stack, and production operation adds collectors, backups, TLS, retention tuning, and ordered upgrades.
your data
Self-hosted telemetry lives in ClickHouse, metadata in PostgreSQL, and transient cache/session data in Redis; Docker uses persistent named volumes.
