Comparison
Openbook vs Microsoft Teams
Microsoft Teams is everywhere because Microsoft 365 is everywhere. It bundles chat, video meetings, and file collaboration with the Office apps most companies already pay for, and its enterprise security and compliance story is as strong as it gets. Nobody was ever fired for choosing it. The everyday experience is another matter: a heavy interface, work management split across Planner, Loop, and SharePoint, and a tool most people use because it was installed, not because they chose it.
Openbook is the opposite kind of product: chosen, not defaulted into. It offers 17 purpose-built room types, Slack-style chat, monday-style boards, a full agile Kanban room, Notion-style docs, whiteboards, retros, a social feed, in one workspace a team composes for itself, starting from 12 one-click space templates. No video calls, and no Office suite attached, which is exactly the trade this page examines honestly.
Openbook is completely free right now — any prices below describe the planned paid tiers.

Credit where due: what Microsoft Teams does well
The Microsoft 365 bundle
If your company pays for Microsoft 365, Teams is effectively included, alongside Word, Excel, Outlook, and SharePoint. Co-authoring Office documents inside Teams is genuinely convenient, and the bundle economics are hard to argue with.
Enterprise-grade meetings and calling
Video meetings, webinars, recording, live captions, and full phone-system calling are mature and reliable at very large scale. For organizations that live in scheduled meetings, Teams handles the load without complaint.
Security, compliance, and admin control
Teams inherits Microsoft's identity, data-governance, and compliance machinery: conditional access, retention policies, eDiscovery, and a long list of certifications that satisfy the strictest IT and legal departments. For regulated industries, that machinery is often decisive.
Where Openbook wins
Purpose-built tools, not a bundle of parts
Work management in Teams means stitching Planner, Loop, and SharePoint together. Openbook's rooms are complete apps: a full agile Kanban board, table boards with nine column types, Gantt with critical path, dashboards wired to boards.
A social layer people actually post to
Openbook's Feed room does announcements, polls, events, kudos, and a bulletin board with birthdays and trending posts, with Group rooms for communities, the intranet layer Microsoft sells separately as Viva.
Knowledge that's findable
A Notion-style Docs room, a Markdown Wiki with live preview, Q&A with voting and accepted answers, and global command-palette search beat files scattered across SharePoint sites and buried chat tabs.
Rituals for modern teams
Retro rooms with 12 formats, scheduled Check-ins with mood tracking and Team Pulse analytics, proofing for creative review, and PTO tracking with capacity charts, none of which Teams offers natively.
Light, composable, and likable
Each space contains only the rooms its team adds, with 12 one-click templates to start. No tabs-of-tabs, no SharePoint plumbing, no add-on licenses to decode, and light and dark mode people actually enjoy.

Choose Openbook if…
- Teams and departments that want tools they'd choose, not tools that came with the license.
- Companies outside the Microsoft stack, or ready to keep Office for files and work elsewhere.
- Remote and async teams that need check-ins, retros, and a feed more than meetings.
Stick with Microsoft Teams if…
- Large enterprises standardized on Microsoft 365, where the bundle price is effectively unbeatable.
- Organizations that live in scheduled video meetings and need full phone-system calling too.
- IT departments with strict compliance requirements already met by Microsoft's governance machinery.
The verdict
Teams wins on bundle economics, meetings, and compliance, and if those decide your purchase, it will keep winning. But the daily work, tracking projects, writing things down, running retros, celebrating wins, happens in Teams grudgingly, spread across Planner, SharePoint, and tabs. Openbook offers 17 purpose-built rooms people actually choose, free to start and $15 per user on Pro. Keep Microsoft for meetings and files if you must; give the work a better home.
FAQ
Common questions
Can Openbook replace Teams for chat?+
For text, yes: channels, DMs, presence, typing indicators, unread badges, and a floating chat widget on every page. Openbook has no video meetings or calling, so companies that live in scheduled calls will keep a meeting tool alongside it.
We get Teams free with Microsoft 365. Why pay for Openbook?+
Because bundled chat doesn't cover work management, retros, check-ins, Q&A, proofing, or a real intranet. Openbook's free plan lets you run a team on all 18 room types at no cost, and Pro is $15 per user per month.
Does Openbook meet enterprise requirements?+
The Business plan at $29 per user per month, $23 annually, adds SSO and SAML, an audit log, API access, advanced permissions, a 99.95 percent uptime SLA, and dedicated support. Microsoft's compliance tooling is deeper; Openbook covers the essentials most teams need.
Can Openbook work alongside Microsoft 365?+
Many teams keep Office for documents, spreadsheets, and email while moving daily collaboration, chat, boards, docs, feed, and rituals, into Openbook. Nothing about Openbook requires leaving Microsoft; it replaces the collaboration layer, not the file formats.
