OpenSourceChoice currently lists 5 projects with an explicit alternative relationship to Skype. Catalog highlights include Rocket.Chat, NextCloud Server, and Element. Rankings follow public GitHub stars and recorded momentum—not paid placement. Match capabilities and license fit to your workflow before adopting any option.
Most catalogued alternatives publish source under OSI or source-available licenses and are free to inspect. Hosting, commercial support, or cloud model APIs may still cost money. Always read the project license for your use case.
Some open-source replacements support self-hosting or local deployment; others are libraries or clients without a server component. Check each project’s deployment docs rather than assuming a drop-in hosted twin.
Map must-have Skype workflows, verify license and compliance fit, run a proof of concept with real data and integrations, then plan ownership for upgrades, backups, support, and an exit path.
Narrow the same alternatives by search, license, tags, or self-hosting signals when you need a tighter shortlist.
