Mobilize vs OpenVolMgr

Mobilize is a web and API platform for mission-driven organizations that organize events and recruit volunteers. Organizations can create single-shift, recurring, and multiple-shift events, as well as virtual and in-person events and actions asking people to call legislators’ offices. Volunteer engagement tools include automated email and text messages, post-event surveys, personalized experiences, and event search and discovery. Organizations can recruit volunteers to host events, create customizable campaigns, reach potential hosts across channels, and set approval processes and permission levels. The platform includes shift scheduling, hours tracking, custom forms, and volunteer self-signup. It provides real-time event data, CSV export, read and write APIs, and SQL mirrors or database replicas. Listed integrations include Salesforce, NGP VAN, EveryAction, PDI, ActionKit, and others. Mobilize says its network includes more than 3,000 mission-driven organizations and over 11 million supporters. Its limited starter account costs nothing and covers 5 team members, the next 5 events or online actions, and up to 50 signups or 500 petition signatures. The service provider is EveryAction, Inc., doing business as NGP VAN.

OpenVolMgr is an open-source resource management platform for nonprofits, shelters, and community-led organizations.

Users can export shift histories as CSV and generate contribution letters. Security guidance includes multi-factor authentication and approved-domain whitelisting. Organizations may self-host on their own infrastructure or request managed deployment with hosting and setup. The managed offer includes priority support and maintenance, while the knowledge base specifies ticketing only for Standard and Enterprise.
