Why choose Spike or Rocket.Chat?
Rocket.Chat has a slightly lower G2 score of 4.1/5 but has a more diverse market segment, including tech and open source. They offer a 30-day free trial, free version, user profile, newsfeed, notes-taking, calendar, task management, "do not disturb" mode, help resources, training webinars, mobile app, web app, desktop app, integrations/API, on-premise options, SAML/SSO authentication, end-to-end encryption, and two-factor authentication. Rocket.Chat also has user and data import capabilities from Slack or CSV. However, Rocket.Chat does not have an entry-level price, screen sharing, audio or group video calls without integration, breakout rooms, recording, participant permissions, subtitles/translations, online document editing, document management, or a dedicated CSM.
