"FiftyOne became a core part of our computer vision workflow"

5/5

What do you like best about Voxel51?

FiftyOne completely changed the way our team explores and validates computer vision datasets.

We use it daily to review model predictions, compare them to ground truth, and quickly identify labeling issues and gaps. The interface is very intuitive, and even new team members pick it up fast.

The Python integration is seamless, which made implementation incredibly easy,

And the feature set is broad and practical, from visualization and filtering to tagging and exporting.

I also really appreciate the active community, providing great customer support.

It’s clear they listen to feedback and continuously improve the product. Review collected by and hosted on G2.com.

What do you dislike about Voxel51?

The pricing can be tough for smaller startups, so we’re currently sticking with the free version. Also, when working with very large datasets (50k+ samples), rendering can take a few seconds between updates. That’s understandable given the scale, but worth noting. Review collected by and hosted on G2.com.

What problems is Voxel51 solving and how is that benefiting you?

Voxel51 solves one of the biggest pain points in computer vision workflows — understanding and managing complex datasets.

Before using FiftyOne, exploring model predictions, finding labeling errors, or analyzing specific edge cases was time-consuming and fragmented.

With FiftyOne, we can now visually inspect, filter, and analyze datasets interactively, which makes debugging models and improving data quality much faster.

It gives us full transparency into how models perform across different conditions, and helps us catch data issues that would otherwise go unnoticed. Review collected by and hosted on G2.com.

"Essential Toolkit for Entrepreneurs Managing Complex, Large-Scale Datasets"

4/5

What do you like best about Voxel51?

FiftyOne makes working with large and messy datasets surprisingly manageable. As a founder juggling complex geospatial and AI data, I found the platform incredibly helpful in organizing, visualizing, and curating my datasets for model development. The visualization module is a standout—it turns raw data into an intuitive, visual interface that makes it easy to spot trends, edge cases, and labeling issues at a glance. It’s also great for getting my team aligned quickly without wasting cycles digging through files. It feels like a tool designed with real-world workflows in mind. Review collected by and hosted on G2.com.

What do you dislike about Voxel51?

Getting started can be a bit technical if you're not familiar with Python environments. While it’s not a dealbreaker, a more interactive onboarding experience or low-code setup would help bring non-technical team members into the loop more easily. Review collected by and hosted on G2.com.

What problems is Voxel51 solving and how is that benefiting you?

As an entrepreneur building in the AI and geospatial space, I deal with large, high-dimensional datasets that evolve quickly and require collaboration across team members. Voxel51’s FiftyOne helps me curate, inspect, and evaluate datasets with clarity and speed, reducing noise and surfacing what matters most. It has been especially helpful in spotting labeling issues and understanding model behavior visually—enabling faster iteration and more confident model deployment.
