# Index settings available in Elastic Cloud Serverless projects
In Elastic Cloud Serverless projects, configuration available to users is [limited](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/3016/deploy-manage/deploy/elastic-cloud/differences-from-other-elasticsearch-offerings#elasticsearch-differences-serverless-settings-availability) to certain index-level settings. These restrictions help ensure the reliability of Serverless projects.
This page lists the Elasticsearch index settings available in Elastic Cloud Serverless projects.
