Flossbank

Flossbank is a funding platform designed to support open source package maintainers through a unique approach that distributes contributions across entire dependency trees. It provides two main methods for developers to contribute: a free option that shows curated, tech-focused ads in the terminal during package installations, or a monthly donation system that directly supports maintainers. The platform ensures that 99% of all contributions go directly to the authors and maintainers of the packages being used.

What makes Flossbank stand out is its comprehensive approach to open source funding. Unlike traditional methods that only support top-level dependencies, Flossbank traces and supports every package in the dependency chain, including those maintainers who lack time for self-promotion. The system works through a package manager wrapper that integrates with existing development workflows without disruption. For businesses, Flossbank offers GitHub Enterprise integration that enables companies to contribute to their entire dependency ecosystem with a single click.

This tool primarily benefits open source developers who want to give back to the community, package maintainers seeking sustainable funding, and enterprises looking to support the open source infrastructure they rely on. Real-world use cases include individual developers opting into terminal ads to support their dependencies, teams setting up monthly donation budgets, and companies using Flossbank Enterprise to fortify their software supply chain through systematic open source contributions.
