Elasticsearch Alternative

OpenObserve vs Elasticsearch

140x lower storage cost on plain object storage. No shards, no JVM tuning. A single binary instead of a cluster. See why teams are replacing the ELK stack.

Teams cut their Elasticsearch storage costs up to 140x.See your ingest-based pricing →Based on OpenObserve's published log-storage benchmark versus Elasticsearch. Actual savings depend on data shape, replication factor, and retention; Elastic Cloud additionally bills ingest and retention per GB.

Why teams switch from Elasticsearch

The many reasons that teams are leaving the ELK stack behind

140x Lower Storage Cost

Columnar Parquet on S3 instead of replicated indices on hot SSDs. Keep months of logs, not days.

No Index or Shard Management

No shard sizing, no rebalancing, no red clusters after a node restart. Stateless nodes, data on object storage.

No JVM Heap Tuning

Written in Rust: no garbage-collection pauses, no OutOfMemory crashes, no heap-size guesswork.

One Platform, Not a Stack

Logs, metrics, traces, dashboards, alerts, and pipelines built in. No assembling Elasticsearch + Logstash + Kibana + APM Server.

OpenTelemetry-Native, No Lock-in

First-class OTLP ingestion plus Elasticsearch-compatible APIs. Data stored in open Apache Parquet; switch anytime.

Single Binary to Petabyte Scale

Start with one binary on a laptop, grow to an HA cluster via Helm. No master, data, and ingest node choreography.

Migrating from Elasticsearch

Moving off ELK is a pipeline cutover, not a data migration. Redirect new data and let old indices age out.

1

Dual-ship from your existing collectors

Deploy OpenObserve alongside Elasticsearch and send data to both. Point Filebeat, Fluent Bit, Logstash, or the OpenTelemetry Collector at OpenObserve; its Elasticsearch-compatible API means most agents only need a new output endpoint.

2

Recreate dashboards and migrate alerts

Translate your key Kibana queries from Query DSL/KQL to plain SQL. Rebuild critical dashboards in OpenObserve and configure alerts with equal or better granularity. Parsing and enrichment move from Logstash to built-in pipelines.

3

Cut over and retire the cluster

Gradually shift production workloads, starting with non-critical services, and validate results side by side. Once retention windows lapse, decommission the Elasticsearch data nodes, and the shard, ILM, and JVM upkeep with them.

"OpenObserve is super fast, definitely very lightweight, and you can get started with an initial POC in two to three minutes to be honest."

Frequently Asked Questions

Common questions about switching from Elasticsearch to OpenObserve

OpenObserve: the open-source Elasticsearch alternative

An open-source, SQL and OpenTelemetry-native observability platform with 140x lower storage costs than Elasticsearch: no shards, no JVM, no cluster babysitting. Radius.ai got started with a working POC in minutes, not months. Also evaluating other tools? See how OpenObserve compares to Splunk, Logz.io, ClickHouse.
