Comparison
Openbook vs Luma
Luma is one of those rare tools people recommend without being asked. Spin up an event on lu.ma and in a few minutes you have a page that looks genuinely good, an RSVP flow with no friction, automatic calendar holds, and reminders that actually get guests through the door. It has become the default for tech meetups, AI community events, and startup launch parties, and community calendars let a scene's events live in one subscribable place. For public-facing events, where the goal is to reach people who do not know you yet and convert their interest into attendance, Luma has quietly set the standard, and it earned that position on product quality.
Internal events are a different problem wearing similar clothes. An all-hands, an AMA with the CTO, a launch review, or a quarterly town hall does not need a public landing page or ticket sales. The attendee list is the company directory. The pre-event questions, the during-event discussion, and the after-event follow-ups belong with the team's other work, not on an external platform where they evaporate once the page stops being shared. Running internal events through a public events tool means another login, another notification stream, and an archive that lives outside the workspace where decisions from those events are supposed to land.
Openbook treats events as part of the workspace. The Event room handles team events with RSVPs, a calendar view, and discussion threads attached to each event. The Townhall room is built for company-wide moments: each event moves through draft, live, and ended stages, RSVP tallies are visible at a glance, per-event guest access lets you bring in an outside speaker or a board member for just that session, and every past event stays in a browsable archive. Both are rooms among 18 types, sitting beside the Chat channels, Docs, Q&A rooms, and boards where the event's inputs and outputs actually live.
This page compares the two honestly. Luma is better at public events, and we will be specific about why rather than hand-wave: ticketing, discovery, reminders, and pages designed to convert strangers into attendees are its territory, and Openbook does not compete there. The real question is where your events happen and who they are for. If you are building an audience, Luma. If you are running the recurring rhythm of a company, all-hands, AMAs, launches, and town halls, the case for keeping those events inside the team workspace is worth fifteen minutes of your attention. Here is the full comparison.

Credit where due: what Luma does well
Event pages that look great in minutes
Luma's pages are the product's calling card. Pick a cover image, write a description, set the time, and the result looks like something a designer touched: clean typography, sensible layout, and themes that make even a casual meetup feel intentional. There is no page builder to fight and no template gallery to get lost in; the defaults are simply good. That matters for public events because the page is the pitch, often the only thing a potential attendee sees before deciding. Plenty of platforms let you publish an event page. Very few make the fast path also the good-looking path, and Luma does.
A frictionless RSVP and reminder pipeline
Registering for a Luma event takes seconds, and what happens afterward is where the craft shows. Guests get confirmations, calendar holds land in their calendars automatically, and reminders arrive as the event approaches, which measurably improves the show-up rate that public events live or die on. Hosts can message registered guests, manage capacity and waitlists, and approve attendees when the guest list needs curating. Check-in at the door is handled too. The entire pipeline from "saw the link" to "walked in the room" is engineered to lose as few people as possible, and that end-to-end attention is genuinely hard to replicate.
Paid events and ticketing
When an event charges admission, Luma handles the commerce: paid tickets, multiple ticket tiers, and payment processing, without the host wiring up a storefront or juggling a separate payments tool. For community organizers running paid workshops, conferences, or dinners, this closes the loop between the event page and the revenue in one place. Openbook does not do ticketing at all, and has no plans disguised as a roadmap footnote here; internal events do not charge admission. If any of your events sell tickets, that requirement alone settles part of your tooling question in Luma's favor, and it should.
Community calendars and discovery
Luma is not just single event pages; recurring hosts get a calendar of their own that people can follow and subscribe to, so a community's whole season of events lives at one link. Subscribers hear about new events without the host rebuilding a mailing list, and Luma's position in the tech and AI event scene means a listing there sits where interested strangers already look. For anyone building an audience over time rather than staffing a single date, that follow-and-subscribe loop compounds: every event grows the list that hears about the next one. Workspace tools have no answer to this, and should not pretend to.
Where Openbook wins
Events live where the team already works
An internal event is surrounded by work: the agenda doc, the questions people want answered, the announcement, the follow-up tasks. In Openbook, the Townhall or Event room sits in the same workspace as all of it, one command-K search away from the Docs, boards, and Chat channels it connects to. Nobody creates an account on an external platform to RSVP to their own company's all-hands, and nobody's question about the event lives in an email thread while the answer lives somewhere else. The event is a room, the workspace is the venue, and everyone is already inside. The announcement goes out on the Feed, the reminder lands in Chat, and the RSVP is one click from either, because they are all the same product.
Draft, live, and ended are real stages
Openbook's Townhall room gives every event an explicit lifecycle. Organizers build the event in draft, invisible to the company until it is ready, flip it live when the moment comes, and move it to ended when it wraps, at which point it joins the past-event archive automatically. That staging mirrors how internal events are actually produced: quietly assembled by a few people, launched deliberately, and then kept as a record. There is no deleting the page or letting it rot at a stale URL. The archive means a new hire can browse every previous town hall, which quietly becomes institutional memory. Ask any long-running company where the recording of the 2023 strategy all-hands lives and you will see why an archive that maintains itself is worth having.
The attendee list is your directory
For an internal event, inviting people should not mean collecting emails; the company is already there. Openbook events draw on the workspace's people directory, with roles and permissions already in place, and RSVP tallies visible at a glance so organizers know exactly where headcount stands. When someone outside the company belongs in the room, an external speaker, a board member, an agency partner, per-event guest access admits them to that event and nothing else, and guests are always free. You get the openness of a public platform exactly where you want it, and the boundary everywhere else.
Discussion is attached, before, during, and after
Openbook's Event rooms carry discussion threads on each event, so the "what should we cover?" conversation, the questions submitted before the AMA, and the reactions afterward accumulate in one place rather than scattering across email and chat. Because the event lives beside the workspace's other rooms, the conversation can grow real structure: pipe questions through a Q&A room with voting and accepted answers so leadership answers the questions people actually upvoted, and post the recap to the Feed where the whole company will see it. A public events tool ends at the RSVP; an internal event is mostly what happens around it. The hour on the calendar is the smallest part; the weeks of conversation on either side are where the value sits, and they need a home.
The follow-through has somewhere to go
Every internal event generates artifacts: decisions, action items, slides, an FAQ someone promised to write. In Openbook, those land in the same workspace as the event itself. Notes go into a Docs room, action items become cards on a Kanban board, the promised FAQ becomes a Wiki page, and the post-launch debrief runs in a Retrospective room with real-time voting on what to change next time. With a standalone events platform, the event ends and the output scatters into whatever other tools the company runs. With Openbook, the town hall and its consequences share an address, permanently and searchably.
Included in every plan, with guests free
Townhall and Event rooms are two of the 18 room types included in every Openbook plan, starting with the free plan, which covers all 18 for up to 10 members and 3 spaces, forever. Pro is $15 per user per month, $12 with annual billing, and guests and viewers never count as seats, so the outside speaker at your AMA costs nothing. There is no separate events subscription and no per-event fee, because events are not a product being metered; they are a feature of the workspace. One bill covers the event, the chat about it, and the work that follows it, which is precisely the set of things a standalone events platform has to hand off to other tools.

Choose Openbook if…
- Companies running a recurring internal rhythm of all-hands, AMAs, launch reviews, and town halls, who want those events living beside the chat, docs, and boards they feed into.
- Teams that want an institutional archive: every past town hall staged, ended, and browsable in the workspace, so context survives reorgs and onboarding.
- Organizers who occasionally need outsiders in the room, because per-event guest access admits a speaker or partner to one event, free, without opening anything else.
- Companies consolidating tools, since Event and Townhall rooms come with all 18 room types on one bill, free up to 10 members, rather than as another subscription.
Stick with Luma if…
- Community builders and meetup organizers whose events are public, where the page itself has to convert strangers into registered, reminded, checked-in attendees.
- Anyone selling tickets, because Luma handles paid tiers and payment processing and Openbook deliberately does not do commerce.
- Recurring hosts building an audience over time, who benefit from followable calendars, subscriptions, and Luma's discovery within the tech event scene.
- Event teams that depend on the show-up pipeline: automated email and SMS reminders, calendar holds, waitlists, approvals, and door check-in.
The verdict
Luma is the best tool going for public events, and it wins on exactly the things public events need: pages that convert, an RSVP-to-reminder pipeline that gets strangers through the door, ticketing when admission is paid, and calendars a community can follow. None of that is faint praise, and none of it is what an internal all-hands needs. Running company events through a public events platform means the RSVP list, the questions, and the record of what was said live outside the workspace, disconnected from the docs, boards, and conversations that the event exists to serve, on a tool built to market to people you have not met.
Openbook's Townhall and Event rooms start from the opposite premise: the audience is already here. Events draw on the people directory, move through draft, live, and ended stages, carry their discussion threads with them, admit outside guests per event for free, and accumulate into an archive the whole company can search. The follow-through, notes, action items, Q&A, and the recap on the Feed, lands in the same workspace, on the same bill as the other 16 room types. If you are building an audience, use Luma. If you are running a company's internal rhythm, Openbook keeps the events where the work is.
FAQ
Common questions
Can Openbook replace Luma?+
For internal events, yes, and usually with room to spare, because the surrounding discussion and follow-up live in the same workspace. An all-hands, an AMA, a launch review, or a recurring town hall maps directly onto the Townhall and Event rooms: RSVPs from the people directory, draft/live/ended staging, discussion threads, and an archive. For public events, no. Openbook has no public landing pages, no ticketing, and no discovery, and it is not trying to grow any. A company that runs internal town halls and public meetups might reasonably use Openbook for the first and keep Luma for the second.
What is the difference between the Townhall room and the Event room?+
The Event room is the general-purpose option for team events: RSVPs, a calendar view of what is coming up, and discussion threads attached to each event. The Townhall room is built for company-wide moments and adds production structure: each event moves through explicit draft, live, and ended stages, RSVP tallies are surfaced for organizers, per-event guest access controls who from outside the workspace can attend a given session, and ended events accumulate in a past-event archive. A team social calendar fits the Event room; the quarterly all-hands with an outside speaker and a permanent record fits Townhall.
Can people outside the company attend an Openbook event?+
Yes, through per-event guest access on Townhall events. A guest is admitted to that specific event, not to the rest of the workspace, which is exactly the boundary an internal event with an external speaker, investor, or agency partner needs. Guests and viewers are always free in Openbook and never count as billable seats, so bringing in an outside panelist has no pricing consequence. What Openbook does not offer is open public registration, where anyone who finds a link can sign up; that is a public-events pattern, and if you need it, it is a genuine reason to use Luma.
Does Openbook stream or host the video for the event itself?+
No. Openbook handles the structure around the event: the RSVP list, the staging from draft to live to ended, the discussion threads, the guest access, and the archive. The live audio or video itself runs on whatever your company already uses for meetings, with the join link on the event. This is a deliberate boundary; teams have strong existing habits around conferencing, and duplicating it poorly would help nobody. Luma draws a similar line for virtual events, integrating with meeting tools rather than replacing them, so on this point the two products make the same call.
How does pricing compare?+
Openbook's free plan is free forever and includes all 18 room types, Townhall and Event rooms included, for up to 10 members and 3 spaces. Pro is $15 per user per month, $12 with annual billing; Business is $29 ($23 annual) and adds SSO, an audit log, API access, and an org-level shared AI key with usage reporting. Every new workspace starts with a 14-day Pro trial, no credit card, and guests never count as seats. Luma is free for many events and monetizes through paid-event fees and its subscription tier; for public events that model is fair and works well.
What happens after an event ends in Openbook?+
The event moves to its ended stage and joins the past-event archive in the room, so the record does not depend on anyone remembering to save anything. The discussion thread stays attached and readable. The real advantage is what surrounds the archive: notes land in a Docs room, unanswered AMA questions carry into a Q&A room where answers can be voted on and accepted, action items become cards on a board, and the recap goes out on the Feed. Six months later, command-K search finds the event, the decisions, and the follow-through together, because they were never in separate tools. That continuity is hard to retrofit and easy to get by default, simply by holding the event where the work already lives.
Does Openbook send reminder emails or texts to attendees?+
Not the way Luma does, and the honest answer is that internal events need less of it. Luma's email and SMS reminder pipeline exists to get strangers to show up, which is the hard problem of public events. Inside a workspace, the event sits on the calendar view, RSVPs are visible, and the people who need nudging are reachable in the same product through Chat and the workspace's own notifications, alongside the announcement on the Feed. If your events depend on multi-channel reminder sequences to drive attendance, that is a public-event problem, and Luma is the right tool for it.
How do we try Openbook for our next all-hands?+
Start a workspace, which begins with a free 14-day Pro trial, no credit card, and create a Townhall room. Build the next all-hands in draft: agenda in a linked Doc, a Q&A room collecting questions in advance so voting surfaces what people actually want answered, and guest access set up if there is an outside speaker. Flip it live, watch the RSVP tally, run the event on your usual meeting tool, then end it and post the recap to the Feed. One event is enough to judge the fit, and afterward the free plan keeps everything for up to 10 members and 3 spaces. The archive entry from that first event is already the start of the record, and the second town hall is easier than the first.
