Support the project

lxml has been downloaded from the Python Package Index millions of times and is also available directly in many package distributions, e.g. for Linux or macOS.

Most people who use lxml do so because they like using it. You can show us that you like it by blogging about your experience with it and linking to the project website.

If you are using lxml for your work and feel like giving a bit of your own benefit back to support the project, consider sending us money through GitHub Sponsors, Tidelift or PayPal that we can use to buy us free time for the maintenance of this great library, to fix bugs in the software, review and integrate code contributions, to improve its features and documentation, or to just take a deep breath and have a cup of tea every once in a while. Please read the Legal Notice below, at the bottom of this page. Thank you for your support.

Note that we are not accepting donations in crypto currencies. Much of the development and hosting for lxml is done in a carbon-neutral way or with compensated and very low emissions. Crypto currencies do not fit into that ambition.
