Pay more money, run slower search ... or not?

Unlike OpenSearch, our goal is to reduce your infrastructure costs. Lower compute, storage, and memory costs — you can have it all without sacrificing speed or accuracy. With innovations like searchable snapshots and autoscaling, you get faster search and efficient resource usage, keeping costs low as your data grows.

  • Proven performance

    Up to 2.4x faster in general search, 2x+ faster for vector search, and 37% storage costs reduction — maximizing performance while minimizing overhead.

  • Optimized data tiers

    With OpenSearch you get premium pricing for basic search. Elastic lets you search fast on low-cost storage and efficient data tiers.

  • Reduced storage footprint

    Reduce log storage by up to 65% with Elasticsearch logsdb index mode, expanding visibility without breaking your budget.

  • Leading vector compression

    Elasticsearch compresses vector data up to 32x with BBQ, reducing memory use by 95% without sacrificing accuracy, and outperforms OpenSearch FAISS.

    A Brazilian bank moved off AWS OpenSearch and implemented Elastic Observability to monitor the entire customer journey, reducing cloud log storage costs by 58%.

  • A US real estate marketing technology startup migrated its applications from AWS to GCP for a lower cost and more up-to-date architecture — cutting its monthly search bill by 42.5%.

  • An online wholesale platform moved off OpenSearch due to lack of performance and support as well as its high costs. After moving to Elastic, the company cited 53% cost savings and excellent performance.

Elasticsearch: Better than OpenSearch

Elastic gives you features that are easier to use and more performant while helping you reduce costs.

A faster, smarter datastore. Elasticsearch handles more data with less cost.

  • Ease of use

    5B+ downloads and counting

    Use the #1 vector database that's 12x faster than OpenSearch. Seamlessly combine keyword search with embeddings for fast, context-aware results.

     

    Simple deployment management

    With AutoOps, get actionable cost insights, see performance recommendations, and rapidly determine root causes.

     

    Built-in NLP models

    Pretrained NLP models like ELSER, Rerank, and E5 are available out of the box (no fine-tuning needed!), making them adaptable to various use cases (e.g., NER).

  • Faster and more powerful

    Fast geospatial queries

    Run complex spatial queries directly in Kibana with better performance.

     

    Efficient time series indexing

    Save up to 54.8% in storage with optimized TSDS (time series data stream) indexing.

     

    Model agnostic integrations

    Connect with leading AI and machine learning platforms, including third-party integrations that OpenSearch doesn’t, like Google Vertex AI.

  • Cost-effective

    Data tiers for smarter data management

    Query data quickly on less expensive storage with searchable snapshots.

     

    Achieve better compression for vectorized data

    Better Binary Quantization (BBQ) gives 32x vector compression with full performance.

     

    Reduce log storage footprint and keep full access

    Logsdb index mode lowers storage needs while keeping all your logs searchable.

Elastic Cloud Serverless: Scalable, secure, and effortless

Elastic Cloud Serverless is the best way to maximize feature benefits and cost savings compared to OpenSearch. Plus, run it where you want to run it — on Azure, GCP, and/or AWS.

  • Search AI Lake architecture

    Say goodbye to the complexities of managing infrastructure. Elastic Cloud Serverless, powered by the Search AI Lake architecture, separates storage from compute and indexing from search. This new architecture ensures high performance while autoscaling indexing and search to meet your workload’s demands.

  • Security and control

    Elastic Cloud Serverless offers robust security, including field and document-level access control, while OpenSearch Serverless does not offer this granularity.

  • Pricing model that aligns with your use cases

    Observability and security are based on ingest and retention, with no minimum cost. Search, on the other hand, may start at just $24/month*, offering a low-cost entry point without the overhead of traditional infrastructure.

    *Estimate based on dev environment with 2GB searchable data, 1% ingest utilization (15 minutes per day), 8% search utilization (2 hours per day)
