Why choose Basecamp or Lark?
Both platforms have roles management and contact management, but Basecamp offers graphic personalization and custom domain name features while Lark does not. Lark has more video call features, including 1-1 and group video calls with up to 500 participants, breakout rooms, recording, and participant permissions. On the other hand, Basecamp offers document viewer and management features, as well as notes-taking and "Do not disturb" mode. Both platforms offer mobile, web, and desktop apps, as well as integrations and API. Lark offers SAML/SSO authentication and both platforms have end-to-end encryption and two-factor authentication.
