Turn any place on Earth into a 3D-printable model — entirely in your browser.
TinyTopo lets you select an area on a map and generates a printable 3D model of the terrain, buildings, roads, water, and greenery inside it, exported as STL or multicolor 3MF. No account, no watermark, no backend — everything runs client-side from open data.
TinyTopo is an open-source spiritual successor to Map2Model, the beloved hobby project that was shut down in June 2026 after its author received legal threats he couldn't afford to fight. This project exists so that can't happen again: the code is open, the app is a pure static site, and anyone can fork and redeploy it. See RESEARCH.md for the full history of the original, how it worked, and the phased plan this project follows.
- OpenStreetMap — buildings, roads, water, land use (ODbL)
- Overture Maps — alternative building source (planned)
- Mapterhorn / AWS Terrain Tiles — elevation
- Nominatim — place search
Pre-alpha. Currently: research and planning. See the phased plan in RESEARCH.md.
See CONTRIBUTING.md. No CLA, ever — contributions are accepted under the project license with a DCO sign-off, so the project can never be relicensed or closed by any single party.
- Code: AGPL-3.0-or-later. Use it, fork it, deploy it — but every derivative, including one offered as a network service, must publish its source under the same terms. TinyTopo can be copied; it cannot be taken private.
- Documentation (README, RESEARCH.md): CC-BY-SA-4.0.
"TinyTopo" identifies this project and its official deployments. The AGPL grants no trademark rights: forks are welcome and encouraged, but public deployments of modified versions should use a different name.
