Why choose Basecamp or Chanty?
Both Basecamp and Chanty offer chat, file sharing, mentions, and groups/channels. However, Chanty offers more features such as voice messages, 1-1 and group video calls, and threads. On the other hand, Basecamp offers more advanced features such as graphic personalization, custom domain name, and participant permissions. Both companies offer mobile, web, and desktop apps, integrations and API, and help resources. Basecamp also offers training (On-Site, Online Live, Docs, Videos), while Chanty offers user and message import from other collaboration software.
