The short version
Miton is source-available, not open-source in the traditional sense.
- You can read the source code. It's all on GitHub.
- You can use Miton for free if you are an individual, a non-commercial user, or part of a small organisation.
- You can modify Miton for your own use.
- You cannot resell Miton or offer it as a competing product until 2028-06-12, at which point this restriction automatically disappears and Miton becomes fully open-source under the Apache 2.0 licence.
Why FSL?
The team behind Miton (Foundry Seven) wanted to ship a source-available product with three properties:
- No rug-pulls. The Apache 2.0 Change Date is fixed. On 2028-06-12, the licence converts automatically. We cannot move that date.
- Defensible IP. Some of Miton's subsystems (smart routing, token condensation, the local-first architecture) are real engineering work. The FSL lets us protect that work for a finite window.
- Open by default. Individuals, non-commercial users, and small organisations can read, run, and modify Miton. We don't gate-keep the everyday use case.
Threshold
The "small organisation" threshold is defined in the FSL text. The short version: organisations with fewer than a defined number of employees and below a defined annual revenue threshold can use Miton under the same terms as individuals.
