Lsos

Open source, sustainable & independent.

The Lsos is a small tool to add pricing to your open source project.

  • Accessible — only larger companies pay a fee.
  • MIT Licensed — code is open source.
  • Funded — sustainable and independent open source.

Free for most, accessible to everyone

We believe price should never stop anyone from building; we ensure that Lsos projects are always free for individuals, small projects, and nonprofits, and that fees are low enough to be accessible for the larger companies who pay.

Open Source

Unlike other financial models, everything stays open source and permissive: source code is MIT licensed.

How it works

Instead of leveraging copyright law, Lsos projects include the Lsos library which verifies that larger companies have a valid activation key.

We developed a novel technique that prevents larger companies from circumventing the fee.

Supported OSS developers

Users of Lsos projects can have the warm and fuzzy feeling knowing that open source developers are being compensated for their work.

Open source developers can dedicate more time on the work they love while larger companies benefit from flourishing open source dependencies.
