Jitsi is an open-source video conferencing tool that excels in security and customization but lacks many collaborative features, making it less suitable for corporate environments. Spark, on the other hand, is a comprehensive collaboration platform that includes chat, file sharing, and user management, making it ideal for business use but potentially overwhelming for personal users.
