How signup works in each app
Events on a home page
You build events with dates and slots on a branded home page and share the link. Participants sign up without a login, authenticated by email.
A private team space with shift signup and chats
Members join your workspace once, then browse and claim what fits their skills and schedule, with a chat channel attached to every task.
What ivolunteer.com is better at
If your workflow depends on the things below, ivolunteer is the right pick.
Signing people in at the door
Premium adds attendance tracking, on-site sign-in, and a mobile sign-in application, so your record shows who actually turned up rather than who said they would. Zelos calculates hours from the shift, not from an arrival.
Recurring slots as a single task
You can build one task that spans a week, several weeks, or a whole calendar month, set how many people you need on each day, then copy the task and shift its dates to roll it into the next month. Zelos posts each occurrence as its own task.
One person signing up a group
Their Block of Slots lets a single participant claim several places at once, bringing three casseroles, or booking four seats for a team, and adjust the number afterwards from their own portal. In Zelos, each person claims their own place.
Limits that don't slam shut
Their participant limits are deliberately soft: signups keep working past the cap, with only some admin features disabled until you upgrade or prune the database. They describe it as an inconvenience rather than a hard stop, which is fairer than most free tiers in this category.
If these bullet points are non-negotiable, you're an ivolunteer customer.
What Zelos is sharper at
If you're coordinating a standing team rather than a series of events, Zelos is a better fit.
Unlimited people, unlimited coordinators
Zelos has no member limit and no admin limit on any plan, including free. Every team lead can post work without moving up a tier. ivolunteer's free plan covers 15 participants and one administrator, with unlimited administrators starting on Premium from $26/month.
Your workspace doesn't expire
A Zelos project stays yours for as long as you use it, with no subscription to renew and no clock on your data. ivolunteer's free plan runs in 30-day blocks you renew by hand, and their own terms note that administrators can log into an expired account for up to a year.
Pricing that doesn't move with headcount
Zelos Pro is $99/month flat whether you coordinate 50 people or 5,000, and the free plan never counts heads at all. ivolunteer prices by the maximum number of volunteers you select, so the bill rises as the roster does.
Chat and push on every plan
Zelos has native iOS and Android apps, push notifications, and two-way messaging with a channel per task, all free, all with admin oversight by design. ivolunteer reaches participants by email, with automated texts on Premium, and has no team chat at any tier.
If you're drawn to this kind of simplicity, you should spin up a free project in Zelos right away.
how long your account lasts
ivolunteer lets admins log into an expired account for up to a year. A Zelos workspace stays yours, with nothing to renew.

Teams that pick Zelos over ivolunteer.com
Volunteer-led nonprofits with growing rosters
ivolunteer prices by the maximum number of volunteers you select, so a roster that doubles moves you up a tier. Zelos doesn't count heads at all: unlimited members on the free plan, and $99/month flat above it.
Learn more →Grassroots and mutual aid groups
Fifteen participants and a single administrator is a tight fit for a group that organises by committee. Zelos gives every organiser admin access for free, with no headcount to watch and no subscription to keep renewing.
Learn more →Event staffing and festival crews
Crews spike for a weekend and shrink after, and mix volunteers with paid staff and contractors. Zelos treats everyone as a member who claims work, at a price that doesn't move with the spike.
Learn more →Contractor pools and gig dispatch
Contractors set their own availability and aren't volunteers at all. Post the job, let the right people claim it, and coordinate in the task chat rather than by email.
Learn more →Brand ambassadors and street teams
Ambassador programmes need lightweight self-signup, targeting and chat, not attendance sign-in and funder exports. Zelos includes only what they'll actually use.
Learn more →Youth programmes and student groups
Both tools count points as well as hours. Zelos adds badges and leaderboards on top, which is what moves participation with younger volunteers. Changemakers Academy took task completion from 20-30% of the group to 75-90%.
