Osm2pgsql is an Open Source project. Your contributions are welcome. You can find the source code and issue tracker on Github{:.extlink}. For some starting points see the contribute page.

Please see for some information about how to contribute.

There is a kind of [road map]({% link contribute/ %}) for osm2pgsql development. It’s not to be understood as a definite “this is what we’ll do” document, but as a rough and incomplete overview of the shared understanding of the maintainers about where we are and in what areas we see need for work.

See also the [generalization project]({% link generalization/ %}).

## Tests and Continuous Integration

Github Actions Build Status

We have a growing suite of tests, new features and bug fixes should always have test coverage.

The master branch and all pull requests are checked automatically using Github Actions (on Linux, macOS and Windows).

## Compatibility

We strive to be out-of-the-box compatible with major Linux distributions to make use of osm2pgsql as easy as possible for many users. Usually at least the last long-term release of the major Linux distributions is supported. This [handy list of dependencies]({% link contribute/ %}) helps with that.

We strive to support all versions of PostgreSQL and PostGIS that are

  • available in the Linux distributions we support, and
  • are supported upstream (i.e. from the PostgreSQL and PostGIS teams).
## License

The software osm2pgsql is available under the GNU General Public License{:.extlink}.
