Open source, with no paid tier

Free. Not freemium, not a trial, not a tier. The source is Apache-2.0 and readable in the repository, and the rule that Rowhouse has no paid tier is one of its own hard rules, checked on every change.

FAQ

Open source, with no paid tier: questions

Could Rowhouse add a paid tier later?

Rowhouse’s hard rules forbid a paid tier, feature gates and any upsell in the product. And because the source is Apache-2.0, anyone could fork the code under another name if that rule were ever broken.

Can I fork Rowhouse?

Yes, under the Apache-2.0 license. The license does not grant the trademark: a fork needs a different name and logo.

How do I report a security issue?

Privately: use GitHub’s Report a vulnerability on the repository, email support@kugamon.com with a subject starting [SECURITY], or submit a case at kugamon.com/support. Please do not open a public issue for a vulnerability.
