Pay $4.5 instead of $12.5

Bring 3 teammates on Flock’s Pro plan for the price of 1 on Slack’s Plus plan. $4.5 vs $12.50. Now collaborate with everyone in your team without burning a hole in your pocket

Aspect image
No need to upgrade users

Have a 100-people strong team, but need only 50 on the pro plan? Simply buy 50 licenses and let everyone else stay on as unlicensed users. No need to pay for every user, unlike Slack

Guests eat (join) for free

Need to invite vendors or clients to work with you on Flock? Simply add them as guests on Flock at no extra cost. Add as many as you need. Flock comes with free multi-channel guests

Flock apps are not just for power users

Using apps should be effortless. Flock apps not only provide slash commands for power users, but also a slick GUI interface for those of us who are command-line challenged. So, you can easily click your way through apps on Flock. Or stick to memorizing complex commands on Slack

Go beyond messaging with To-dos, Polls & more

Aspect image

Create and assign tasks, get notified of updates and more with Flock’s built-in Shared To-dos

Aspect image

Conduct live rich polls, with images and anonymous voting

Aspect image

Automated mailing lists for each channel so you can send emails when chat is not the best medium

Smart membership rules for channels

Need a channel for all software devs in the Boston office or one for everyone reporting to Mark? Flock’s Smart Channels allow you to set channel membership rules. Employees meeting the criteria will be auto-added to the channel. Slack teams will have to add channel members one by one
