// cómo funciona

Cómo funciona

  1. Clarify your goal

    Decide cloud versus self-hosted, and design your first application package — document schema, indexing and a ranking profile — before writing data.

  2. Get the project

    Clone vespa-engine/vespa from GitHub (or use the install path in the run steps below) and skim its README for the parts relevant to your goal.

  3. Install and configure

    Start from the official getting-started guide: deploy an application package to Vespa Cloud or to your own Docker-based instance.

  4. Run your first task

    Deploy the sample application, feed a few documents, and run a query with a vector-plus-text ranking profile to see hybrid retrieval work.

// características

Por qué gusta tanto

Hybrid search in one engine

Vector search, classic text search and structured filtering are evaluated together in a single query path.

Tensor-based ranking

Ranking uses tensor computation, so ML model inference happens inside the search engine at query time.

Built for big data

Designed for large corpora and high query loads with horizontal scaling and multinode redundancy.

Recommendation and serving

Serving and recommendation are first-class uses alongside search, sharing the same application model.

Cloud or self-hosted

Run applications on Vespa Cloud (with a free trial) or operate your own Vespa instance from the same open-source code.

Sample applications

A companion sample-apps collection provides fully functional, production-ready starting points.

Ejecútalo tú mismo

  1. Clone the repository

    Get the source from the official GitHub repository for vespa.

    git clone https://github.com/vespa-engine/vespa.git
    cd vespa
  2. Start with the getting started guide

    Create and deploy your first Vespa application package to Vespa Cloud or your own instance, following the official guide the README links.

    # Follow https://docs.vespa.ai/en/getting-started.html to deploy a sample app — see README
  3. Build from source (developers)

    For Vespa itself, set up the documented dev environment (including JDK 17) and build the Java modules.

    brew install jenv mvnvm openjdk@17  # macOS dev setup example from the README; see its Building section

Preguntas frecuentes

Who maintains vespa?

vespa-engine (the Vespa team, originally from Yahoo), through the vespa-engine/vespa repository, with the service at vespa.ai.

Is vespa free to use?

Yes — the project is open source under the Apache-2.0 license as recorded for this listing. See the license terms for any conditions on redistribution.

Does vespa need a paid API key?

No API key is needed to self-host the Apache-2.0 engine. Vespa Cloud is a paid managed service (with a free trial) if you prefer not to operate it.

How does Vespa compare to a standalone vector database?

A vector database does nearest-neighbour lookup. Vespa is a full search platform — text, vector, structured data, tensor ranking and model serving in one distributed system — more powerful for production search, and correspondingly more system to learn and run.

How do I get started with vespa?

Clone the repository (or use the documented installer), follow the install and configure steps on this page, and run the smallest real task first — deploy the sample application, feed a few documents, and run a query with a vector-plus-text ranking profile to see hybrid retrieval work.
