Flock vs Rock

Flock

• Small and mid-sized teams that want chat, calls and to-dos in one app
• Teams that want polls, notes and reminders built into their chat
• Nonprofits, which can ask for special pricing

Rock

• Agencies and freelancers who bring clients into project spaces as guests
• Growing teams that want a flat bill instead of per-seat pricing
• Small teams replacing a separate chat app and task board

Flock

• Starter is meant for teams of 1 to 20 members, searches only 10,000 messages and has 10 public channels.
• Group video calls are capped at 20 participants and, like screen sharing, need Pro or Enterprise.
• Guests are free for 90 days from the invitation, then billed at the same rate as team members.
• Single sign-on and Active Directory sync are listed under Enterprise, which is priced by quote.

Rock

• The Free plan stops at 3 group spaces, 5 members per space, and 50 tasks and 50 notes per space.
• Video and audio calls run through Zoom, Google Meet or Jitsi; Rock does not host calls itself.
• Sprints, recurring tasks, custom fields, time tracking, webhooks and Zapier are limited to the Unlimited plan.
• Rock does not offer refunds; a canceled plan stays active until the end of the billing period.

Flock

Channels and direct messages

Public channels open to the whole company, private invite-only channels, and 1-1 and group messages, with an All Channel feed that gathers new messages in one place.

Video and voice calls

1-1 video calls are on the free plan. Pro and Enterprise add group video calls with up to 20 participants and screen sharing. Voice notes can be sent in any channel.

To-dos, notes, polls and reminders

Discussions can be turned into shared to-dos with due dates, alongside team notes organized by channel, anonymous polls and reminders.

File sharing

Files are shared in chats and channels. Storage is 5 GB for the whole team on Starter, 10 GB per member on Pro and 20 GB per member on Enterprise.

App store and API

The app store lists integrations such as Google Drive, Asana, Trello, Jira, GitHub and Zoom, with webhooks and developer documentation for building custom apps.

Admin and security controls

Paid plans allow multiple team admins and multiple approved sign-up domains. Single sign-on and Active Directory sync are listed under Enterprise.

Rock

Spaces for each project or client

A space is a project room with its own chat, tasks, notes, files and meetings. 1:1 spaces are unlimited on both plans; the Free plan allows 3 group spaces.

Messaging

Real-time chat in every space with threads, reactions, mentions, voice messages and polls. Scheduled messages and the pinboard are part of the Unlimited plan.

Tasks in board, list and calendar views

Tasks take assignees, due dates, labels and checklists. Sprints, recurring tasks, custom fields and the time tracker need the Unlimited plan.

Notes and files

Write briefs and meeting notes inside a space, and keep uploads next to linked folders from Google Drive, Dropbox and OneDrive. Free spaces hold 250 MB of uploads each.

Meetings through Zoom, Meet and Jitsi

Start a Zoom, Google Meet or Jitsi call from the message bar and the join link is posted to the space. All three integrations are included on the Free plan.

Rock MCP and custom API

An MCP server lets assistants such as Claude, Codex and Cursor read spaces and create tasks, notes and messages on both plans. The custom API, webhooks and Zapier need Unlimited.
