This is a project supported by F-Droid, I just learned about via a mention in their 2025 retrospective blog post;
"funding.json is a manifest that enables Free and Open Source Software (FOSS) projects to declare their financial needs in a machine-readable format. The self-contained JSON file can be easily published in repositories or websites, functioning similarly to robots.txt or Progressive Web App manifests.
By making funding requirements publicly crawlable and indexable, funding.json makes aims to bring discoverablity to FOSS projects, helping connect those seeking financial support with potential backers."
Seems like it’s worth all fediverse apps creating one of these manifests. I wonder if this could be adapted for use in supporting other kinds of creators?
Also whether it could be used with Murmurations. So community organisations could include up-to-date info about their funding needs in their entries on directory sites that source data via the Murmurations protocol.
