    Leaflet was created 11 years ago by Volodymyr Agafonkin, a Ukrainian citizen living in Kyiv.

    Volodymyr is no longer in Kyiv, because Russian bombs are falling over the city. His family, his friends, his neighbours, thousands and thousands of absolutely wonderful people, are either seeking refuge or fighting for their lives.

    The Russian soldiers have already killed tens of thousands of civilians, including women and children, and are committing mass war crimes like gang rapes, executions, looting, and targeted bombings of civilian shelters and places of cultural significance. The death toll keeps rising, and Ukraine needs your help.

    As Volodymyr expressed a few days before the invasion:

    If you want to help, educate yourself and others on the Russian threat, follow reputable journalists, demand severe Russian sanctions and Ukrainian support from your leaders, protest war, reach out to Ukrainian friends, donate to Ukrainian charities. Just don't be silent.

    Ukrainians are recommending the Come Back Alive charity. For other options, see SupportUkraineNow.org.

    If an appeal to humanity doesn't work for you, I'll appeal to your egoism: the future of Ukrainian citizens is the future of Leaflet.

    It is chilling to see Leaflet being used for documenting Russia's war crimes, factual reporting of the war and for coordination of humanitarian efforts in Romania and in Poland. We commend these uses of Leaflet.

    If you support the actions of the Russian government (even after reading all this), do everyone else a favour and carry some seeds in your pocket.

    Yours truly,
    Leaflet maintainers.


    Leaflet

    Leaflet is the leading open-source JavaScript library for mobile-friendly interactive maps. Weighing just about 39 KB of gzipped JS plus 4 KB of gzipped CSS code, it has all the mapping features most developers ever need.

    Leaflet is designed with simplicity, performance and usability in mind. It works efficiently across all major desktop and mobile platforms out of the box, taking advantage of HTML5 and CSS3 on modern browsers while being accessible on older ones too. It can be extended with a huge amount of plugins, has a beautiful, easy to use and well-documented API and a simple, readable source code that is a joy to contribute to.

    For more info, docs and tutorials, check out the official website.
    For Leaflet downloads (including the built main version), check out the download page.

    We're happy to meet new contributors. If you want to get involved with Leaflet development, check out the contribution guide. Let's make the best mapping library that will ever exist, and push the limits of what's possible with online maps!
