Free under BUSL-1.1
Use it in production. No invoice required.
Read the source, run loctree on private repos, ship products that depend on it, scan customer codebases as part of a paid service you sell. The Additional Use Grant covers all of this — as long as the product you sell is not Loctree itself.
Fit: internal teams, consultancies, SaaS platforms, OSS projects, AI agent tooling.
Commercial license
Hosting Loctree as a service. Reselling its functionality.
Offering Loctree (or a substantial portion of its functionality) to third parties as a hosted, managed, or commercially distributed service that competes with the Licensor requires a commercial agreement. One email is enough to start a conversation about scope, terms, and pricing.
Fit: managed services, white-label products, embedded redistribution, enterprise OEM.
Apache-2.0 in 2030
Automatic conversion. No renegotiation, no lock-in.
On 2030-04-13 — four years after the first BUSL-1.1 publication — the license converts to Apache License 2.0 by the terms of the BUSL itself. No action required from us or from you. The version of Loctree you depend on today will be Apache-2.0 by then.
Fit: long-horizon teams, regulated buyers, anyone who needs an OSI-permissive endpoint.
BUSL-1.1 is source-available (not OSI-approved open source) until the Change Date of 2030-04-13.
In short: use Loctree freely in your work, but email us if you want to sell it as your own service. The license explicitly states — in a few years it will be fully open-source anyway.
BUSL parameters (Licensor, Additional Use Grant, Change Date, Change License) appear in the License section linked from the footer of this site.
