Cerebro Alternative for Elasticsearch & OpenSearch
A modern Cerebro replacement with historical metrics, anomaly detection, alerts, and expert support - for Elasticsearch and OpenSearch.
What is Cerebro?
Cerebro is an open-source Elasticsearch web admin tool built in Scala and AngularJS. Its last release is v0.9.4 from April 10, 2021, and the upstream repository (lmenezes/cerebro) has been dormant since. Cerebro shows the current state of a cluster - nodes, indices, shards, mapping - but it does not record history, detect anomalies, or send alerts.
Pulse is the modern Cerebro alternative for Elasticsearch and OpenSearch monitoring. It keeps the cluster-admin views Cerebro is known for - nodes, indices, shards - and adds historical metrics, AI-powered anomaly detection, automated root-cause analysis, alerting to Slack, PagerDuty, and Discord, and access to Elasticsearch and OpenSearch experts under SLA.
Dashboards Cerebro never had
Proactive monitoring starts with great dashboards.
Pulse features expertly crafted dashboards that provide smart observability for Elasticsearch and OpenSearch environments. Make informed decisions about cluster health and performance through best of class nodes, indices, and shards dashboards which also provide the bottom line.
Pulse's unique approach includes specialized visualizations like Shard Heatmap and metrics grouping by index pattern, offering deep performance insights with drill-down capabilities across node tiers and availability zones. These dashboards, originally developed by our experts for their own use, encapsulate years of optimization expertise to help users effectively monitor and maintain their clusters.

FAQ
Is Cerebro still maintained?
Cerebro's last release is v0.9.4 from April 10, 2021. The repository (lmenezes/cerebro) has received no new releases since, and the project is effectively dormant. Teams still using Cerebro on modern Elasticsearch 8.x or OpenSearch 2.x deployments routinely hit compatibility gaps.
What is the best Cerebro alternative for Elasticsearch monitoring?
Pulse is the closest modern alternative to Cerebro for cluster monitoring: it provides node, index, and shard views, plus historical trends, anomaly detection, and root-cause analysis that Cerebro never offered. Pulse supports Elasticsearch 7.x/8.x/9.x and OpenSearch 1.x/2.x/3.x out of the box.
Does Cerebro support OpenSearch?
Cerebro was built before OpenSearch existed. It may partially work with OpenSearch 1.x because of API compatibility with Elasticsearch 7.10, but it has no first-class support and breaks on newer OpenSearch versions. Pulse supports OpenSearch natively.
What does Pulse offer that Cerebro does not?
Pulse adds historical metrics, anomaly detection, configurable alerts to Slack/PagerDuty/Discord, automated root-cause analysis, daily health assessments, and 24/7 expert support under SLA. Cerebro only shows the current state of the cluster as a snapshot.
How do I migrate from Cerebro to Pulse?
Pulse connects to your cluster via the standard Elasticsearch/OpenSearch HTTP API using a read-only user. There is no agent to install on data nodes. Most teams are fully monitored within 15 minutes of signup and can decommission Cerebro the same day.
