falsify is released under the MIT License. You can use it, modify it, ship it, and fold it into a commercial product without paying anyone. That's not going to change.
This page is for the case where you want something more than MIT gives
you — support, SLAs, private patches, a name other than falsify, or a
written commercial agreement your legal team can sign.
Contact hello@falsify.dev if
you are:
- Deploying falsify in a SaaS product and want vendor support.
- Embedding falsify in a regulated environment (healthcare, finance, government) and need a signed SLA or liability agreement.
- Building a managed
falsify-as-a-service offering and want co-marketing or a commercial license that waives MIT attribution. - Looking for custom features, private patches, or prioritised bug fixes.
- Interested in white-labelling the CLI under a different brand.
- Planning a fork that would re-use the "falsify" name or the chevron logo — see the trademark policy below.
Please include:
- Your company and use case (one paragraph).
- Deployment scale (users, requests/day, internal vs external).
- What you'd want from a commercial engagement (support, features, branding, etc.).
Response time: usually within 3 business days.
The MIT License covers the source code. It does not cover the "FALSIFY" name or the chevron logo.
You may:
- Use "falsify" to describe what the software does ("we use falsify internally").
- Link to github.com/studio-11-co/falsify in docs and blog posts.
- Mention "falsify" in academic papers with standard attribution.
You may not, without prior written permission:
- Publish a product, service, or fork using "falsify" (or a confusingly similar name) in its title.
- Use the chevron logo in marketing for a non-falsify product.
- Imply official endorsement or partnership.
Forks are welcome under a different name and logo.
falsify will remain MIT-licensed. Upstream development happens in the public repo. Commercial licenses coexist with the open-source distribution — they add a signed agreement, they do not remove code from the community.
