Neovim operates a Bountysource campaign to fund ongoing development. This makes it possible for core developers to work full-time for a month or longer, accelerating projects like Lua integration, the VimL engine, extended marks, embedded terminal, job control, and the RPC API.
Current sponsors are featured in the left column of this page. These are companies or individuals contributing a monthly amount to help support Neovim.
If you're pledging $5/month or more and want to have your URL listed, send a pull request with a new entry for your Bountysource slug in the js/sponsors-override.js file. If you don't have a GitHub account, you can write to the Neovim mailing list.
You can obtain your Bountysource slug with the following command:
curl --header 'Accept: application/vnd.bountysource+json; version=2' 'https://api.bountysource.com/supporters?team_slug=neovim&per_page=10000&page=1' 2> /dev/null | python -m json.tool | grep -C5 $NAME | grep slug
$NAME by your Bountysource display name as shown in the sponsor list.
