StreetComplete is an easy-to-use OpenStreetMap editor for Android that enables contributors to improve map data without requiring knowledge of OSM tagging schemes.
The tool solves the problem of making OpenStreetMap contribution accessible to casual mappers by breaking down data collection into simple, location-based questions. Rather than requiring users to understand complex tagging systems, StreetComplete automatically identifies nearby locations where surveys are needed and displays them as quest markers on a map. When a user taps a marker, they answer a straightforward question—such as "What is the name of this road?"—and the app automatically processes the answer and uploads it to the OSM database in properly formatted changesets. The approach is designed for on-site surveying, with offline capability and minimal data usage.
StreetComplete suits anyone interested in contributing to OpenStreetMap who prefers a mobile-first, question-driven workflow over traditional editing interfaces. It is particularly valuable for mappers doing field surveys who want to collect and submit data without needing to learn OSM conventions. The app works best for quest types that can be answered through simple questions, which naturally limits its scope to straightforward data collection tasks rather than complex edits.
The project maintains active engagement with its community across multiple contribution channels. Development includes regular addition of new quest types, with a community-managed wiki documenting available quests. The project actively solicits and integrates translations, welcomes issue reports and testing feedback, and provides clear pathways for contributors to suggest and implement new quests without requiring programming knowledge. Documentation is organized to support both technical contributors and non-technical participants interested in tasks like solving notes or spreading awareness of the tool.
