License & Pricing

TractStack is released under FSL-1.1-MIT. This is a mostly permissive non-compete license that converts to MIT two years after each release.

The authors of the FSL license describe it well: “Many SaaS companies wish to make the source code for their core products available under permissive terms without the risk of harmful free-riding.”

Simply put, TractStack is free even for commercial use. However, you cannot re-sell TractStack “as a service” without explicit consent.

Use TractStack for commercial projects
Modify the source code for your needs
Build client websites and charge for your services
Deploy on your own infrastructure
Create internal business applications
Distribute your modifications (under same license)

Sell TractStack as a hosted service
Compete directly with TractStack’s business model
Redistribute as a commercial product

Technically, no. Not yet. In practical terms you are free to use TractStack as though it were MIT open-source. Commercial use is encouraged!

Each release converts to MIT license after two years. In the meantime, the only prohibited use is re-selling “TractStack as a Service” without explicit consent.

If you’re an agency or developer looking to leverage TractStack for client work, you’re completely covered. Build as many sites as you want, charge your clients, modify the code - all permitted under FSL.
