Book a meeting room without leaving Slack.
Type /book in any channel. Tell Lobby who’s coming and when. Get back the rooms that are actually free for that slot — and drop the meeting into your Google Calendar or Microsoft 365 in one tap.

Four taps from “we need a room” to “booked”.
Most calendar tools ask you to pick a time first and figure out which rooms are free after. Lobby asks the questions in the order your team already asks them: who’s coming, when, and is there anywhere we can sit.
- 01
Anyone types
/book(or/room) in any Slack channel or DM. - 02
A short dialog asks how many people, the date, and the time.
- 03
Lobby replies privately with the rooms that are actually free for that slot.
- 04
One tap opens the room in Google Calendar or Microsoft 365 with the time pre-filled. Hit save. Done.
Two commands. One result.
There’s nothing to learn beyond a single slash command — and if your muscle memory reaches for a different word, that works too.
The commands
/book
The default. Asks how many people, when, and how long. Returns the free rooms. One tap and it’s booked.
/room
Same command, different muscle memory. Some people type /book, some people type /room. Both work, both do the same thing.
- ✓ Only rooms you have permission to book
- ✓ Only rooms that are free for the time you asked for
- ✓ Room name and capacity
- ✓ A "Book this room" tap that opens your calendar with the time and resource pre-filled
- ✓ The reply is visible only to you — the channel doesn’t see it
Because the conversation is already there.
Most office tools assume people will switch to them. Slack assumed the opposite — bring the tools to the channel — and ate the office category for it. Meeting room booking is one of the last small jobs nobody quite finished pulling into chat. /book finishes the job.
Your team doesn’t have to learn a new tool, get a new login, or remember which tab the room booker lives in. They type a slash, then a number, then a time. Anyone can teach anyone the whole thing in 15 seconds.
What the Slack integration does. And what it skips.
What the Slack integration does
- ✓
/bookand/roomslash commands in any channel or DM - ✓ Filters rooms by people, date, time — only shows rooms you can actually have
- ✓ Privately shows you the result (no spam in the channel)
- ✓ One-tap deep link into your existing Google Calendar or Microsoft 365 calendar
- ✓ Honours the same calendar permissions you already have on each room
What the Slack integration skips
- ✗ No bot in the channel — Lobby replies privately, doesn’t broadcast
- ✗ No second booking system — the meeting is a normal Calendar event
- ✗ No "approve booking" workflow — if you can book it in Calendar, you can book it in Slack
- ✗ No DM reminders, no follow-ups, no nudge bots
- ✗ No new permissions to manage — your existing Google / Microsoft access rules win
- ✗ No data stored that wouldn’t already be in your calendar
Live in 3 steps.
No deployment, no admin project. If your rooms are already in Lobby, the Slack rollout is one authorise click.
- 01
Connect Lobby to Slack.
Dashboard → Chat integrations → Slack → “Connect to Slack”. Authorise once for the whole workspace.
- 02
Pick which rooms are bookable.
Lobby uses the rooms you already connected from Google Workspace or Microsoft 365. Toggle visibility in Rooms if you need to.
- 03
Type
/bookanywhere.That’s the whole rollout. Anyone in your Slack workspace can use it from the moment it’s connected.
Slack integration is included on the Pro Unlimited plan — $60/month, billed yearly at $720/year. Same flat rate whether you connect 3 meeting rooms or 1,000.
