TL;DR
StreetComplete is a mobile app that allows users to contribute small, targeted updates to OpenStreetMap through simple quests. The project aims to improve map data accuracy by encouraging more community participation.
StreetComplete is a mobile application that enables users to contribute small, specific updates to OpenStreetMap through a series of guided questions, or ‘quests.’ The project aims to increase community involvement and improve map data accuracy by making editing accessible and straightforward.
The app presents users with simple, localized questions such as ‘Is this road one-way?’ or ‘What is the name of this building?’ Users answer these prompts without needing extensive mapping knowledge. Since its release, StreetComplete has seen rapid adoption among casual mappers and volunteers, contributing thousands of updates to OpenStreetMap.
Developed by a team led by German programmer Sebastian Klein, StreetComplete emphasizes ease of use, requiring only a smartphone and internet connection. The app integrates directly with OpenStreetMap’s API, submitting verified edits once users complete quests. The project is supported by the OpenStreetMap Foundation and has been praised for lowering barriers to contribution.
Potential Impact on OpenStreetMap Data Quality
By simplifying the editing process, StreetComplete encourages broader participation from casual users, which can lead to more accurate and comprehensive map data. This is especially important in under-mapped regions, where detailed data is scarce. Improved data quality can benefit various sectors, including navigation, urban planning, and disaster response, making the project relevant beyond the mapping community.

Background and Growth of Community Mapping Tools
OpenStreetMap, launched in 2004, relies on volunteer contributions to build a free, editable map of the world. Despite its success, the complexity of editing tools has historically limited participation to more experienced mappers. Recent developments, such as StreetComplete, aim to democratize editing by providing user-friendly interfaces. The app builds on previous efforts like Mapillary and OsmAnd, which also seek to expand community engagement and data accuracy.
Recent updates in 2023 and 2024 have seen increased interest in mobile-based contributions, with StreetComplete emerging as a leading tool for quick, targeted edits. Its gamified approach and straightforward interface have been credited with boosting contributions, particularly in regions with low mapper density.
“Our goal is to make editing OpenStreetMap as simple as answering a few questions, so more people can contribute without technical barriers.”
— Sebastian Klein, developer of StreetComplete
