8 Best New Relic Alternatives & Competitors (2026)

Elastic Observability combines Elasticsearch, Kibana, and APM with machine learning features. It is highly customizable and can run on-prem, yet it lacks Mezmo’s purpose-built agentic orchestration and MCP-based dynamic tool discovery for production SRE agents.

Datadog is a full-stack observability SaaS platform with strong log management, APM, and recent AI copilots. It excels at unified dashboards and alerting but sends far more raw data to the cloud than Mezmo and lacks an open-source agent orchestration layer comparable to AURA. Pricing is usage-based and typically higher for high-volume telemetry.

Splunk provides enterprise search and analytics for logs and metrics with SOAR automation capabilities. While powerful for security and compliance use cases, it does not emphasize 99.98% data reduction or open-source multi-agent SRE workflows the way Mezmo does, and its licensing model is often considered expensive for continuous high-ingest scenarios.

Dynatrace delivers AI-driven observability with Davis causal AI and broad auto-instrumentation. Its strength lies in enterprise-scale root cause analysis, but it does not expose an open-source Rust agent harness or the same level of token-efficient telemetry reduction for custom LLM agents.

Honeycomb focuses on high-cardinality observability and developer-centric querying for distributed systems. It is excellent for tracing but does not provide Mezmo’s multi-agent orchestration framework or 99.98% pre-agent data reduction.

Sumo Logic is a cloud-native log and security analytics platform with machine learning insights. It offers strong search and compliance features yet centers on SaaS ingestion rather than Mezmo’s infrastructure-resident agent control plane and curated context engineering.

Grafana Labs provides open-source visualization, Loki for logs, and Tempo for traces with alerting. While highly flexible and cost-effective for dashboards, it does not include Mezmo’s AURA-based agentic SRE workflows or MCP tool integration for autonomous incident response.
