# JOSM

11 Hacker News commenters recommended JOSM and 11 criticized it, November 2025 to November 2026. It was recommended in 4 of 13 months.

**Verdict:** Power users recommend it as the main desktop OpenStreetMap editor for advanced, capable mapping. Common caveat: it is clunky and hard for beginners.

## Why people recommend it

- Powerful desktop editor for advanced mapping (5 comments): "JOSM is a great power user tool, but this article's recommendation to use it for your first edit is misguided."

([source](https://news.ycombinator.com/item?id=49467914)) "something like the JOSM desktop editor that has more capability" ([source](https://news.ycombinator.com/item?id=49483999))
- Strong for detailed desktop mapping (2 comments): "Yes, josm is an ugly java tool but this did not prevent me from doing a lot of mapping back in the days." ([source](https://news.ycombinator.com/item?id=49694232)) "which is, for some things, way better than doing it on-the-walk with a smartphone" ([source](https://news.ycombinator.com/item?id=49488053))
