I've made browser extension for Firefox and Chrome, so that when you buy online, portion of the money goes to extremely effective, research-backed charities (no extra costs for the user).<p>There are about 1000 partner shops, including Etsy, Aliexpress, Barnes&Noble. Hopefully eBay soon as well!<p>Source code is available on github: <a href="https://altruisto.com/Altruisto/altruisto" rel="nofollow">https://altruisto.com/Altruisto/altruisto</a><p>It's also on ProductHunt: <a href="https://www.producthunt.com/posts/altruisto-2" rel="nofollow">https://www.producthunt.com/posts/altruisto-2</a><p>Any feedback, suggestions, and pull requests much appreciated!
