AlternativeTo
alternativeto.net
A crowdsourced directory that finds free and open-source alternatives to any software, app, or web service — covering desktop, mobile, and web platforms with community ratings and filtering by platform and licence.
Why it is useful
The fastest way to find a free or open-source replacement for any tool you want to stop paying for — or stop using entirely. Search for any app, and the community has already ranked the best alternatives by how similar they actually are. Filterable by platform, licence type, and whether it is self-hostable.
