Free to start. A flat fee when your team joins.
One person and a few workspaces costs nothing, indefinitely. Paid plans are a flat monthly fee that already includes your seats — not a per-head charge that grows every time someone joins.

Enterprise
Let's talk
Over 100 people, or off the shared service
No caps on any axis, audit export, and two ways to run it off the shared service — self-hosted or dedicated. See below.
- Unlimited workspaces, documents, members and storage
- Version, trash and audit history kept indefinitely
- Bulk audit export
- Self-hosted or dedicated deployment, quoted separately
Prices in USD, billed monthly. Pay annually and it's 20% off — including the extra-seat rate on Team. Tax is added at checkout where it applies.
Enterprise
Two ways to run it on your own terms.
Past a hundred people, or anywhere the answer to "where does this data live" has to be something specific, the shared service stops being the right shape. Both of these are the full product with every Enterprise entitlement — the difference is who operates it.
Self-hosted
You run itMarkbase deployed inside your own environment, in the region you choose, operated by your team. Your documents, their history and everything derived from them stay behind the perimeter you already defend.
- Runs in infrastructure you own and control
- Nothing bespoke to operate and no hardware to buy
- Your security review, on your terms
Dedicated
We run it for youYour own isolated deployment in your cloud account, operated by us. You get the boundary and the region you need without your platform team taking on another service to run.
- Single-tenant — no infrastructure shared with anyone else
- Deployed into your account, on the provider you already use
- Upgrades, backups and monitoring are ours to do
Deployed on the provider you already use
- AWS
- Google Cloud
- Azure
- Hetzner
- DigitalOcean
Somewhere else? Ask — the list is where our customers already are, not a limit.
Tell us roughly how many people, where it needs to run, and what your compliance people will ask. We'll come back with a shape and a number.
How seats work
You buy a plan, not a headcount.
The seats are in the price
Pro includes five people and Team includes ten. An org of two on Team pays $40 — the same as an org of ten. There is no minimum to hit and no per-head arithmetic to do before you know the bill.
Growth is only priced on Team
Past ten people, each additional seat is $5 a month ($48 a year, the same 20% off). Pro doesn't grow — its fifth seat is its last, and the move from there is to Team.
A seat is a member, not an invitation
Pending invitations cost nothing. The bill changes when someone accepts, prorated against the period you've already paid for, and again when someone is removed.
One hundred is a real ceiling
Team refuses the 101st member rather than quietly billing for them. If you're heading past that, Enterprise is the conversation — and it's a cheaper one than an invoice you didn't expect.
Every limit, in one table
What each plan actually enforces.
These are the numbers the API checks, not marketing rounding. Cross a limit and the write is refused with a clear error rather than silently costing you money.

What we promise
The parts that matter when something goes wrong.
Billing is the part of a product where the small print decides whether you can trust the rest of it. These four are how Markbase behaves, and they're built into the system rather than left to goodwill:
- Nothing starts billing on its own. The free plan stays free with no card on file. You move to a paid plan by choosing one, and a trial never converts behind your back — because there is no trial.
- A failed payment is a fortnight, not a cliff. Nothing about your access changes for fourteen days while a card is retried, and we tell you it's happening. Your agents don't stop mid-run because an expiry date passed.
- A downgrade doesn't destroy anything. Dropping to a shorter history window doesn't retroactively delete what's already there. Everything stays readable, searchable and exportable; only new creates are refused once you're over a cap.
- Your content leaves in the format it arrived in. It's plain Markdown and ordinary files. There's no proprietary export to reverse-engineer and nothing that only opens in our app.
Questions
The ones worth asking.
- Is there still a free plan?
- Yes, and it isn't a trial. One person, three workspaces, 200 documents each and 500 MB, with the same hosted MCP endpoint everyone else gets. No card, no countdown, no expiry.
- I was using Markbase during the beta. What happened to my account?
- Nothing was taken away. Every existing organization was placed on a plan that already fits what it holds, so no workflow that worked the day before started failing — and no card is on file, so nothing began charging.
- What does 'includes 5 seats' actually mean?
- The monthly fee is flat and covers that many people. You are not billed per person up to that number, and you don't get a discount for using fewer. On Team, and only on Team, people beyond the included ten are $5 a month each.
- How does annual billing work out?
- It's 20% off twelve months: Pro is $192 a year instead of $240, Team is $384 instead of $480, and Team's extra seats drop from $5 a month to $48 a year. You can switch between monthly and annual at any time.
- What happens when I upgrade or downgrade?
- An upgrade applies immediately and is prorated against the period you've already paid for. A downgrade takes effect at the end of that period — you keep what you paid for until it runs out, and you can undo it any time before then.
- What if a payment fails?
- Nothing changes for fourteen days. Full access, full limits, and we tell you — repeatedly — rather than degrading anything quietly. If it's still unpaid after that window the organization moves to Free, where everything stays readable, searchable and exportable.
- What happens to my content if I stop paying?
- It stays yours and it stays readable. Nothing already in version history or trash is destroyed by a downgrade, and it's plain Markdown and ordinary files on the way out — no proprietary export to reverse-engineer.
- Do you charge tax?
- Prices are exclusive of tax. Where a jurisdiction requires it, it's calculated and added at checkout, and it appears on the invoice.

Free plan, no card
It costs nothing to find out.
The fastest way to know whether a shared workspace fixes what your agents keep getting wrong is to give them one for an afternoon. Sign in with Google or GitHub — there's nothing to install, and the free plan doesn't ask for a card.
