Pixeltable: The Unified Multimodal Backend for AI Data Apps
Explore Pixeltable, the Apache-2.0 multimodal data backend that stores, queries, and versions images, video, audio, and text with a Python-native dataframe API.
Building AI applications means wrangling messy, multimodal data: images, video, audio, text, and tables that all need to stay in sync. Pixeltable tackles this head-on with a unified, open-source data backend designed specifically for AI workloads. It combines a Python-native dataframe API with automatic data versioning, so your datasets behave like code — replayable, forkable, and branchable.

Traditional databases store rows and columns — not videos, embeddings, or model outputs. Pixeltable stores everything in one place: media files in cloud object storage, metadata in Postgres, and complex transforms computed incrementally. You query it all with familiar dataframe operations.
Core Capabilities
| Capability | What It Gives You |
|---|---|
| Data versioning | Replay, fork, and branch datasets like Git |
| Multimodal types | Images, video, audio, text, and structured columns |
| Incremental compute | Transforms and embeddings recompute only changed rows |
| Model inference | Run LLMs and vision models directly in the dataflow |
Use Cases
Pixeltable shines in RAG pipelines (indexing documents, images, and transcripts), computer vision dataset management, evaluation sets for LLM agents, and any workflow where reproducibility matters. Because every operation is recorded, your dataset lineage is always auditable.
💡 Self-hosted by design: Apache-2.0 licensed, runs in Docker, and keeps your data under your control — no vendor lock-in.
Pixeltable is a strong choice for teams that want reproducibility and full control over their AI data stack. It is under active development with a growing community on GitHub (1.6K+ stars).
