iTOL access modes and subscription models

With the constantly growing number of active users and uploaded trees, we have tried to find a sustainable model to maintain and extend iTOL, as well as provide technical support to our user base. Therefore, starting with 1st of October 2020, certain aspects of iTOL require an active subscription, as detailed below. For academic users, we offer individual and institution-wide subscriptions. For companies, individual and company-wide subscriptions are available. Please visit the pricing information page for a detailed list of all available options.

If you have any questions, or need additional information about the iTOL access modes, please contact us.

iTOL access modes

Free access

Users without an active individual or institutional subscription can continue using iTOL in free access mode. All iTOL annotation features remain fully accessible, with the following restrictions:
  • Trees uploaded anonymously (i.e. without an iTOL account) are removed after 48 hours.
  • Tree annotations can be added normally, but cannot be saved. After completing the annotation, users have to export their figures right away.
  • Batch upload mode is not available.
  • Existing trees in user's account can be viewed and exported without restrictions, but no new annotations, parameter changes or views can be saved.
  • User account can be used normally, with unlimited creation of workspaces and projects. New trees can be uploaded into user projects as usual, but any new tree annotations, views or parameters cannot be saved.

Standard subscription

  • All iTOL features are available without restriction.
  • Tree annotations, parameters and views saved during an active subscription remain accessible indefinitely, even when the subscription expires.
  • Trees and data uploaded through the batch mode during an active subscription remain accessible indefinitely, even when the subscription expires.
  • Therefore, an active subscription is required only when users want to add new annotations to their trees, create new saved views, or use the batch upload.

iTOL annotation editor subscription

  • Includes all features of the standard subscription
  • Full, unlimited access to the iTOL annotation editor for Microsoft Excel and Google Sheets
  • All tree annotations created with the editor during an active subscription remain accessible indefinitely, even when the subscription expires.
