Voxel51 FiftyOne

FiftyOne by Voxel51 is an open-source, data-centric platform for curating, visualizing and debugging computer-vision and multimodal datasets, with an enterprise edition for teams.

FiftyOne is a data-centric platform for building high-quality visual AI. It provides an interactive app and Python SDK to explore, filter and search large image, video and multimodal datasets using metadata, visual similarity and natural language, and to surface related or edge-case samples. Teams can evaluate model performance, trace poor metrics down to individual samples, and compare multiple models to understand and fix failures. Built on an open-source core with a plugin ecosystem, FiftyOne is widely adopted by computer-vision research teams and had over 10,000 GitHub stars as of 2026. Voxel51 also offers FiftyOne Enterprise (Teams) with collaboration, security and scaling, and has extended the platform toward physical AI with synchronized playback, curation and annotation for multimodal time-series data. It suits ML and computer-vision teams that want to improve dataset quality rather than just train on raw data.
