Before you choose
Compare free access and paid plans
Some entries provide a no-cost plan. Paid pricing is shown where a maker publishes a starting figure.
A free trial is also offered by items on this list. Review each trial's conditions before transferring a workload.
Deployment should fit your stack
Listed services run through web interfaces or APIs, on self-managed installations, and on Linux, macOS or Windows. Pick the model that aligns with your application's runtime.
A managed web service can differ from a self-hosted setup in how you operate the database.
Check index and search controls
Compare the index types supported by a tool, its maximum vector dimensions and its metadata-filtering controls.
Hybrid search is a separate comparison point. Look for it when your application needs vector and other search methods together.
Review backup handling
Managed backups are part of the comparison. Verify that your chosen setup supplies them and suits your operating approach.
Consider the code model
Some listed tools publish their code under open-source terms. When code access or modification matters, inspect the licence alongside deployment needs.
