Elasticsearch

Elasticsearch is Elastic's distributed search and analytics engine, not a leftover 7.10/8.0-only vector note, and not only a China marketing URL. LICENSE.txt is a triple license (AGPLv3-only, SSPLv1, Elastic License 2.0) by default; x-pack is Elastic License only. elastic.co/elasticsearch sells Search, observability, vector database, and Jina AI models as part of Elastic. Cloud paths are Serverless, Hosted, and self-managed, each with a free trial / download. elastic.co/pricing/serverless-search prints as-low-as VCU units: ingest $0.14/VCU-hour, search $0.09, ML $0.07, storage $0.047/GB-month, egress $0.05/GB. Point the website at the global product page, not /cn/.

Compare Vespa if you wanted another search+ranking engine with Cloud units, Qdrant if you wanted a dedicated vector engine, and Pinecone if you wanted Free / $20 / $50 min / $500 min.

Key Features

Search engine first, vectors included: Live page lists vector database as one workload beside logs, search apps, and threat protection. Do not freeze kNN as a 7.10-only add-on.
License is not Apache-2.0: Quote the triple license / Elastic License. Do not call the default tree MIT or Apache.
Cloud is trial + units: Serverless search pricing on the public page is "as low as" VCU hours. Hosted and self-managed stay on elastic.co/pricing.
Website should not be the CN path: Leftover elastic.co/cn/elasticsearch/ is dropped.

Use Cases

People who will self-manage the download and accept AGPL/SSPL/Elastic License terms.
Teams that will start a Cloud trial and then read VCU units.
People comparing 77,791 stars against Vespa 7,052 or Qdrant 34,018.

Limitation: "As low as" VCU rows are not a quote for every region or vector profile. Confirm the calculator.

Getting Started

Open elastic.co/elasticsearch, not the leftover /cn/ URL.
Confirm elastic.co/pricing and the serverless-search unit page.
Confirm Qdrant if you wanted a dedicated vector Cloud Free node.
Do not paste 7.10/8.0 as "the latest version."

Frequently Asked Questions

Is it free?

Self-managed source is downloadable under the published licenses. Cloud is a trial plus units.

Is it Apache-2.0?

Not as the default. GitHub LICENSE.txt is AGPL + SSPL + Elastic License, with x-pack Elastic-only.

Same as Pinecone?

No. Pinecone prints Free / $20 / $50 min / $500 min. Elasticsearch Cloud on the public page is VCU "as low as" rows.

Alternatives

Vespa: Apache-2.0 search/serving engine; Cloud has a unit table.
Qdrant: Dedicated OSS vector engine plus Cloud.
Pinecone: Managed vector DB with public dollar seats.

Tips

Quote 77,791 stars and the triple license from the GitHub check.
Point website at elastic.co/elasticsearch.
Confirm VCU "as low as" before you treat $0.14 as the whole bill.

Conclusion

Elasticsearch is a 77,791-star search engine with AGPL/SSPL/Elastic License terms and Cloud VCU units, not a leftover 8.0-only vector blurb. Start at elastic.co/elasticsearch, then decide whether Qdrant or Vespa already covers the engine you need.
