Vector databases store and search vector data; choose by deployment options and the search and filtering features your project needs. The platform details here cover API, self-hosted, web, Linux, macOS and Windows. They do not specify Android apps, so check whether you can manage your database from an Android device before choosing.

Choosing well
Where does the database need to run?
Start with deployment: decide whether you need an API, a self-hosted setup or a web interface. Platform availability varies, so confirm the option you need before comparing features.
If you plan to work from a Xiaomi, Redmi or POCO phone or tablet, check for Android access. The platform details here do not identify Android apps.
Which search features do I need?
Compare hybrid search and sparse-vector support if your application needs to search beyond dense vectors. The chart also compares index types and maximum dimensions.
Check the feature details against your data and workload rather than assuming a database supports a capability because it is in this category.
Do I need metadata filtering?
Choose a database with metadata filtering if your searches need to narrow results using associated information. Confirm how the feature works for your use case.
Can I start with a free plan?
The chart compares free plans and paid starting prices. Check the current plan terms and pricing before you commit; a free plan and a free trial are different things.
For example, Chroma and EmergentDB list free plans, while their paid starting prices differ.
Can I read or change the database code?
Check the licence if you need to inspect or modify the code. The chart compares open-source status; Zvec and Vearch are listed as open source.
Questions people ask
Which vector database has an Android app?
The platform details here do not specify Android apps. Check the product’s current platform information if you need to manage a database from an Android phone or tablet.
What should I compare when choosing a vector database?
Compare deployment, hybrid search, metadata filtering, sparse-vector support, maximum dimensions, index types and SDK languages.
Can I use a vector database for free?
The chart compares free plans and paid starting prices. Check the current terms for the database you are considering.
What is the difference between a free plan and a free trial?
A free plan is listed separately from a free trial in this chart. Check the product’s terms to see what access each option provides.
Can I self-host a vector database?
Self-hosted deployment is one of the deployment options compared. Confirm that the database you choose supports the setup and platforms you need.
