Software you own.


Sellsword Software builds applications for people who want durable software, local control, and fewer moving parts.
Even this site is built with plain static HTML/CSS and vanilla javascript.

Principles

Build for ownership, not dependence.

Own your data

Products should keep working without a service deciding whether your workflow is still allowed.

Own your software

Licenses should be straightforward and deployment targets should stay portable.

Own Stability

Built on a reliable, stable foundation, rather than slop dependencies.
