Labelbox is a popular data labeling platform, offering tools for various industries and use cases. 

Labelbox labels data like images, text, and documents, making it a good choice for AI and machine learning projects. Key features include data labeling, quality assurance, integration with machine learning frameworks and data management tools, and an intuitive interface. 

Yet, Labelbox does come with its own set of constraints, including issues with native video rendering, restricted DICOM compatibility, and a pricing structure that may not adapt effectively to scalability.

For these reasons, we will explore alternatives to Labelbox.

  • An advanced Python SDK and API access, coupled with effortless export capabilities in JSON and COCO formats, enhance flexibility and integration with external systems.
  • Auto-find and fix dataset biases and errors like outliers, duplication, and labeling mistakes.
  • Integrated tagging for data and labels, including outlier tagging.
  • Employs quality metrics (data, label, and model) to assess and improve ML pipeline performance across data curation, data labeling, and model training.


iMerit is a data labeling service provider known for its annotations and management solutions. Unlike traditional labeling platforms, iMerit offers a service-based approach to data annotation.

iMerit Key Features and Benefits

  • Customizable solution for annotation, analysis, categorization, segmentation needs.
  • Get insights from metrics such as the annotator's working hours, the number of objects per hour and more.
  • iMerit also provides a free trial for it’s users, but has no mention of it’s pricing plan on it’s website.
  • iMerit’s user interface may be less intuitive and user-friendly for beginners. 

TELUS International

TELUS International, formerly Playment, is a Labelbox alternative that focuses on specialized data labeling services, offering features tailored to specific use cases, ensuring user comfort.
