About Infinite Loop Development Ltd
Infinite Loop Development Ltd is a small Irish software development company, founded in 2004. Many of our projects are open sourced for the benefit of the developer community. We believe in giving back — building tools that others can use, inspect, and build upon freely.
We are proud to be an Arctic Code Vault Contributor, recognised by GitHub for contributions that have been preserved for future generations in the Arctic World Archive. Our contributions span several widely-used open source ecosystems:
Arctic Code Vault Contributor
- CocoaPods/Specs — the central repository for iOS & macOS library specifications
- apache/cordova-docs — documentation for the Apache Cordova cross-platform mobile framework
- zchee/golang-wiki — a comprehensive Go programming language wiki
Our most popular open source repository is infiniteloopltd/AuthenticatorAPI.com, where we have helped countless developers secure their apps and websites using Google Authenticator-compatible two-factor authentication (TOTP). The codebase is free to inspect, self-host, and contribute to.

Why Sponsor?
Running a public API service isn't free. Server hosting, bandwidth, maintenance, and SSL certificates all incur real costs. While this API will always remain free to use, your sponsorship directly helps ensure it stays online, fast, and well-maintained.
