Everything you need to know about OSS Funding Matcher

Yes, OSS Funding Matcher is 100% free for open source maintainers and contributors. There are no credit cards required, no hidden tier fees, and no charge for evaluating repositories or generating pitch drafts.
Derived from the Open Source Security Foundation (OpenSSF) Criticality Score project, it is an algorithmic metric (from 0.0 to 1.0) that measures a repository's activity, ecosystem impact, contributor density, and dependency influence to quantify project importance.
No. OSS Funding Matcher evaluates program eligibility and synthesizes tailored pitch drafts for you to review and edit. Because several funders operate nomination programs, open call LOIs, or custom application forms, you retain full control to submit the final pitch directly.
