What Is Label Studio?
Label Studio is an open-source data labeling tool from HumanSignal that handles text, images, audio, video and more. The Community edition is free and self-hosted, and sources agree on that, but not on the licence: one review says Apache 2.0 with no seat cap while another says MIT, so check the GitHub repository. The hosted Starter Cloud plan is where prices conflict: most sources say $99 a month with $49 per additional user and a maximum of 12 users, one reviewer saying they verified this on the HumanSignal pricing page in August 2026, while G2, updated April 2026, lists $149 a month for 12 users. I could not check the official page myself, so treat the price as $99 or $149 until confirmed.
Enterprise pricing is not published and is custom-quoted, and it is where RBAC, SSO and LDAP, audit logs, reviewer workflows, agreement metrics and project dashboards live, according to one source. The practical split is simple: the free Community edition covers solo and small-team labeling that you run yourself, the Starter Cloud plan saves you from hosting, and Enterprise covers governance and larger annotation operations. Self-hosting means you handle storage, backups and upgrades, and you pay for the servers or cloud you run it on. For model-assisted labeling at scale, teams often compare it with commercial platforms.
Label Studio suits ML teams that want a flexible, free labeling tool they can customise. Compare Labelbox, Scale AI and Roboflow. Browse the MLOps & Infrastructure tools directory for more.
