Yes. It can be embedded in your Python application and does not need a client-server model. ### Where is ChromaDB data stored in client-server mode, and what port must be reachable? Use the --path flag when running chroma run to set the storage directory. If other apps connect to it, port 8000 must be reachable, and Docker can map it with -p 8000:8000. ### How should a multi-user ChromaDB setup created with Python's AdminClient be backed up? Create the AdminClient with is_persistent=True and point persist_directory to a folder you can back up. That folder stores database and tenant information, so losing it can make recovery difficult. ### How often are tagged ChromaDB packages released? New tagged versions of the pypi and npm packages are released on Mondays. Hotfixes can go out at any time during the week. ## Alternatives - Algolia: Algolia helps product teams connect their users with information by providing the building blocks they need to create fast, relevant, perso… - Elasticsearch: Elasticsearch is a distributed search and analytics engine that indexes and queries full-text, log, metric, and vector data in near real ti… - Manticore search: Open source search server designed to be fast, scalable and with powerful and accurate full-text search capabilities derived from Sphinx se… - OpenSearch: OpenSearch is an open-source search and observability suite for self-hosters who need scalable indexing, analysis, and visualization of log… --- Source: Our Local Host (https://ourlocalhost.com/app/530/chromadb), the self-hosted and open-source app directory.
