HacktoberFest 2025 was a successful event for LocalStack, with developers worldwide contributing to the open-source project by focusing on improving documentation and enhancing the developer experience. The event saw 18 contributions across various repositories, with 14 merged pull requests and participation from 15 unique contributors, including 12 first-timers. The majority of the contributions aimed at clarifying examples, updating outdated sections, and making guides more user-friendly, demonstrating the importance of documentation in open-source projects. Despite a backlog of pull requests, the team maintained a 78 percent merge rate and learned valuable lessons about the benefits of clearly scoped issues and the need for more volunteer reviewers. Looking ahead, LocalStack plans to expand its issue templates, add intermediate-level sample-app issues, and host more community events to foster ongoing collaboration. The event underscored the significance of clarity and collaboration in maintaining the strength of open-source projects, and LocalStack expressed gratitude to all participants for their contributions.
