Scalar's 2025 Open Source Pledge

What is OSS Pledge?

You can read more about it here, but in short, it's paying Open Source maintainers. The minimum to participate is $2,000 per full-time employed developer per year.

Open source is the foundation everything we build sits on. In 2025, Scalar is made up of 10 developers and contributed $21,232 directly to open source maintainers -- $2,123 per developer.

We sponsored the following maintainers and projects:

• tiangolo (FastAPI)
• SaltyAom (ElysiaJS)
• hey-api
• litestar-org (LiteStar)
• colinhacks (Zod)
• daveshanley (libopenapi)
• mholt
• yusukebe (Hono)
• Aslemammad
• pi0 (Nuxt / UnJS)
• typst
• MathurAditya724
• fuma-nama
• thibaultleouay (OpenStatus)
• dmonad (Yjs)
• marijnh (CodeMirror / ProseMirror)
• LinusBorg (Vue.js)

Most of us got into engineering through open source. We're glad to give back -- and we're proud to be members of the Open Source Pledge again in 2025.
