This feature is in alpha

Expect rapid changes, limited features, and possible breaking updates. Share feedback as we refine the experience and expand access.

Vector buckets have default limits during the alpha phase. These limits are designed to ensure fair resource allocation and can be adjusted on a case-by-case basis for production workloads.

Storage limits

Limit	Value	Notes
Buckets per project	10	Maximum number of vector buckets per Supabase project
Indexes per bucket	10	Maximum number of indexes per bucket
Vector dimensions	Max 4096	Maximum dimension size for embeddings
Batch size	1000 vectors	Maximum vectors per single insert/update request

Query limits

The queryVectors limits differ between hosted and local vector buckets.

Limit	Hosted vector buckets	Local vector buckets
Maximum `topK`	10,000	100
Maximum results per response	100	100
`nextToken` query pagination	Supported	Not supported

Hosted vector buckets use Amazon S3 Vectors. When a response includes a nextToken, send the same query again with that token to retrieve the next page. Local vector buckets use pgvector and return the requested results in one response.
