Sponsorship

OpenIAP is the open interoperability standard for in-app purchases. Your sponsorship directly funds the infrastructure, security, and documentation that the entire mobile and game ecosystem depends on.

This isn't about supporting "a nice open-source project." Sponsoring OpenIAP reduces your company's costs and risks:

Benefit	What It Means for You
Reduced bus factor	Multiple maintainers and a governance structure ensure the project doesn't depend on one person
Interoperability standard	One specification across iOS, Android, and emerging platforms — less integration work for your team
Conformance and test matrix	Shared behavioral tests run every store implementation through the same expectations, so normalization regressions are caught before they reach your production apps
Security verification profiles	Industry-standard receipt validation and fraud prevention patterns you don't have to build yourself
Documentation and onboarding	Better docs means your developers ship faster with fewer support tickets
Release stability	Funded testing and CI/CD infrastructure means fewer breaking changes
Platform policy response	When source stores change billing APIs, we update the spec so you don't scramble
Ecosystem trust	Neutral governance gives all parties confidence to adopt and contribute

Sponsorship Channels#

OpenIAP keeps project money and personal maintainer support on separate, clearly labeled rails:

Channel	Use It For	Where the Money Goes
OpenCollective	Corporate sponsorship tiers, project funding, IAPKit community instance infrastructure	The project fund, with a public ledger — expenses (hosting, maintainer compensation per the budget allocation) are transparent
GitHub Sponsors	Personal appreciation for the maintainer's work	The maintainer directly — disclosed here for transparency, and separate from project accounting

What Your Funding Supports#

Area	Activities
Specification Development	GraphQL schema evolution, IR codegen plugins, new platform bindings
Security	Verification profiles, receipt validation patterns, audit-ready schemas
Testing Infrastructure	Conformance tests, CI/CD pipelines, cross-platform test matrix
Documentation	API docs, migration guides, tutorials, AI assistant context
Community	Contributor onboarding, mentorship programs, conference presence
Operations	Hosting, domain, CI compute, release management

The Security Value#

OpenIAP is more than developer experience — it's purchase infrastructure with a security layer:

Purchase verification profiles — standardized server-side validation
Receipt validation best practices — cross-platform guidance to prevent manipulation
Transaction integrity — audit-friendly schemas with structured logging
Secure provider interoperability — safe handoffs between stores and apps
Fraud reduction — shared patterns to detect and prevent purchase fraud

By building security into the standard itself, every library in the OpenIAP ecosystem inherits these protections — reducing risk for the entire community.
