Twenty years ago, a group of open-source enthusiasts in Taiwan came together to organize the first COSCUP (Conference for Open Source Coders, Users & Promoters). It began as a small gathering of 200 people, with the goal of uniting Taiwan's open-source community. Today, COSCUP has grown into a major event with over 3,000 participants. Along with its growth, tools and open-source projects were developed to be shared by Taiwan's open-source community—some of which are now being used internationally. This talk will introduce two key shared projects that have emerged from this journey. - OPass (Open Pass & All Pass - Community Checkin with Interactivity Project) OPass is a comprehensive event management tool, available as a web app, iOS, and Android application. Its features include self-service ticket scanning, agenda management, real-time notifications, and gamification modules. With simple JSON configuration files, OSS events can seamlessly integrate its API to access these services. Originally adopted by COSCUP, OPass is now widely used by other major events in Taiwan, including HITCON and PyCON TW. To enable its continued distribution on iOS and Android platforms, OCF acts as a non-profit custodian managing the app’s accounts for the community.

OSCVPass: Open Source Contributor VIP Pass. A project jointly developed by OCF and the community, connecting open-source contributors across Taiwan. Since its launch in 2019, the project has recorded over 600 contributions. Historically, many OSS events in Taiwan offered free tickets or additional benefits, such as photography services or snack bars, to individuals contributing to open-source projects. However, verifying these contributions required significant effort. OSCVPass simplifies the process by organizing a review committee made up of event organizers and community members. Approved contributors can use their OSCVPass to access these benefits across multiple events throughout the year.

The OPass App has extended its reach beyond Taiwan, with forks developed in India and interest from local government agencies for their events. OSCVPass, originally centered on OSS events, is now attracting collaborations with technical and commercial events, broadening its scope and impact.
