Pixeltable

Pixeltable
open source / Overall score: 1.8

Pixeltable is a unified multimodal backend for AI data apps. It stores images, video, audio, documents and structured data in one table interface, indexes embeddings, and runs models and transformations from computed columns declared on insert, in place of separately gluing together blob storage, a vector database and an orchestrator.

Openness

5 high confidence
5.0
license
Apache-2.0(OSI)
source
public
core features withheld
no

Pixeltable's Apache-2.0 repository is public and builds the whole library. Its README describes no enterprise edition or license-gated build; Pixeltable Cloud, in limited beta, runs the same application file as a hosted service beside the library rather than holding any part of it back.

Adoption

1 high confidence
1.0

Pixeltable is an embedded Python library with no separate server, so its PyPI package is the product itself, not a client to one, and its downloads are a direct usage signal.

Capability

3 medium confidence
3.0

Pixeltable stores, indexes and serves its own data and runs models inside computed columns, but self-hosted it is a single node: its operations guide allows one process to write the database and points to Pixeltable Cloud, still in limited beta, for more. Its documentation describes no cluster or distributed mode, and running models only lifts a product above that when it also scales across machines. That leaves it level with pgvector, another single-node store.

    Cloud page: "Run the same application file against a hosted database"; "Pixeltable Cloud is in Limited Beta."; it describes a hosted database and media store, not a cluster mode.

    Infrastructure page: "Default home is `~/.pixeltable`: `pgdata` (PostgreSQL), `media` (generated files), `file_cache` (downloads)", with generated media on "local disk, or the Cloud database's home bucket" or an S3 destination.

    Operations page: "One Python process writes to `~/.pixeltable/pgdata`. Several API workers need a shared volume and still one writer. Two pods on the same `pgdata` corrupt the database." and "If you need more than one process writing the database, use" Pixeltable Cloud.

    README: "Pixeltable is the database, orchestration, and serving layers"; "A transform is a computed column. An index is a declaration, and so is an HTTP route."; "Pixeltable Cloud is in Limited Beta."
