An AGPL-3.0 application with Apache-2.0 SDKs, and nothing withheld from the published source, which is the top rung: an OSI license, public source, no gated core. The whole application is in the repository, with no enterprise directory, no second license and no license key; self-hosting is documented as a first-class path; and the vendor's own FAQ says of the hosted tier "Currently, we are not charging anything for Langtrace cloud". Neither argument for holding it lower survives: AGPL copyleft sits on the OSI rung alongside Apache, and a hosted product sold beside an otherwise complete open core does not gate that core.

There is no ee/, no enterprise/, no second LICENSE below the root, and no license-key module. GitHub's license endpoint returns AGPL-3.0 for the single root LICENSE. The published tree is the whole application and it self-hosts from the docker-compose file in it.

  The vendor's own statement of the split and of the cloud tier. License section: "Langtrace application(this repository) is licensed under the AGPL 3.0 License" and "Langtrace SDKs are licensed under the Apache 2.0 License." The feature list includes "Self-hosting Option: Deploy on your own infrastructure", and the FAQ answers "Can I self host and run Langtrace in my own cloud?" affirmatively. On price: "What is the pricing for Langtrace cloud? Currently, we are not charging anything for Langtrace cloud and we are primarily looking for feedback so we can continue to improve the project. We will inform our users when we decide to monetize it." A cloud tier that charges nothing cannot be the paid tier a core is withheld for.
