Find open source alternatives

Every page here answers one question: what is the open source alternative to a proprietary app you already know? We track 72 popular tools - Photoshop, Slack, Notion, Figma and dozens more - and each one links to the maintained open source projects that can replace it. The framing is deliberately practical: cancel a subscription, move the work to software you can self-host and own, and keep your data on your own infrastructure. The count beside each app is how many alternatives we currently list. Open any page to compare the options side by side, with live GitHub signals so you can see what is genuinely maintained.
