AlternativeTo helps you find alternatives to software you want to replace. You search for an app, and the site shows a list of similar tools with user ratings, platform filters, and license information. The Database covers over 100,000 applications across desktop, web, and mobile. Recommendations come from the community, which means you can discover niche tools that aren't widely advertised.

It's especially useful when you want to replace a paid subscription with a free or open-source option, or when you're looking for software that runs on a platform the original doesn't support. The site has been running since 2009 and is maintained by a small team in Sweden. There's no algorithm deciding what you should use — just crowdsourced suggestions and honest user opinions.
