Updated
In short: Label Studio is ranked #1 of 28 as of 4 October 2026, ahead of Roboflow and CVAT. The best-ranked option with a free plan is Roboflow. The lowest first paid tier on this page is CVAT at $1.92/mo.
Labeling images for datasets or visual review involves choosing annotation methods and workable outputs. Compare annotation types and image formats, then check dataset export and model-assisted labeling. API access and team collaboration can matter when a workflow needs shared work or integration; free plans and paid-from pricing add budget context. The ranking begins with Label Studio, CVAT, and Roboflow, followed by BasicAI and Labelbox. Consider which annotation types and file formats your work requires, and how each option’s export, access, and collaboration capabilities fit the way you handle image data.
28 image annotation software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
