Chronosphere Application Observability vs Robusta

Chronosphere Application Observability is a cloud service for helping teams find and resolve problems in cloud-native applications and microservices. Chronosphere Lens creates service views aligned with an application’s architecture. Teams can use RED metrics and service-level objectives to understand performance and service dependencies, while metrics, logs, traces, and events are correlated with system changes and their effects. Distributed tracing maps request paths across components to help locate latency and inter-service communication issues. Dynamic trace sampling is offered to balance observability insight with cost. The service accepts open telemetry formats including Prometheus and OpenTelemetry. Listed alerting connections include Slack, PagerDuty, OpsGenie, VictorOps, email, and a general-purpose webhook. Pricing for the Observability Platform is based on useful data retained and customized for each organization; no price is listed. Pilots are typically free and average 2–3 weeks, though large-scale or long-term pilots may be paid. A free trial is offered, but there is no free plan. Customer support includes year-round, 24/7 communication through Slack, Zendesk, or email, with optional office hours and calls.

Robusta is an AI SRE offered through SaaS, a customer VPC deployment, or full self-hosting with the customer’s own LLM key. It learns an environment, groups duplicate alerts, filters noise, and surfaces new issues. When an alert arrives, its AI investigates root cause and blast radius, proposes a fix, and escalates to a human when needed. Alerts can enter through webhooks, HTTP requests, or MCP events, with listed tools including Prometheus AlertManager, Grafana, Datadog, PagerDuty, and Jira. Holmes provides native integrations for Kubernetes, OpenShift, AWS, Azure, GCP, Prometheus, Grafana, PostgreSQL, GitHub, and ServiceNow. Other sources can connect through MCP servers or HTTP APIs, including generated HTTP connectors. Customers may use their own models and API keys and disable Robusta-hosted models. The agent is read-only by default; write access for auto-remediation is optional. Queries, log lines, and conclusions are logged and replayable. Robusta says customer data is not used for model training and that it is SOC 2 compliant. Pricing is on request.
