What Crowdstack is
Crowdstack is a web-based community engagement platform for administrators and members. Communities can use public, private, or featured channels, while members can message one person or a group privately. Sign-in supports email and password, Google, or Facebook. Administrators can define custom profile fields, and administrators and moderators have private Whispers for management coordination. The platform lists advanced moderation, private groups, direct messaging, custom domains, and spam-detection integrations. Crowdstack says all plans use TLS/SSL for transmitted data and describes daily and point-in-time backups, redundant storage, weekly off-site backups, and encrypted off-site backup transfers. Midstack costs $999 a month and Fullstack costs $1,499 a month, each with unlimited members, page views, bandwidth, and file storage. Fullstack is required for premium memberships, with Crowdstack Pay retaining 7.5%.
