Why choose Monday or Spike?
In terms of features, both platforms offer add-ons, roles management, custom domain names, and contact management. However, Monday has workspace and user activity tracking, while Spike has chat, file sharing, mentions, voice messages, groups/channels, GIF and emoji support, threads, and video calls. Spike also has notes-taking, a calendar, and end-to-end encryption, but does not have integrations or API, on-premise options, or two-factor authentication like Monday.
