What the free tier gives you, what the paid tiers add, and how many boards your hosting plan already includes.
Boards is priced per organisation, not per person. There is no per-seat charge and there will not be one — inviting a client should not cost you anything, because inviting clients is the whole point of the product.
One board and five collaborators, on any account, with no plan and no card. It is not a trial and there is no clock on it. It is enough to run one real project and decide whether this works the way you work.
Every Agency hosting plan includes boards, along with API and MCP access:
So check your plan before buying anything. If you are on an Agency plan, boards are included and the only reason to look at the standalone tiers is if you want more boards than your tier carries.
Boards Pro adds unlimited boards and unlimited collaborators, plus automations, the AI card drafting and summaries, and the two-way GitHub Projects sync.
Boards Business adds the public API and our MCP server, so a script or an AI assistant can drive your boards, and white-label branding on shared boards.
Live prices are on the Zinn® Boards page — we do not print them here, because a price in a help article is a price that goes stale.
Live boards. Archived boards do not count. If you hit your limit, archiving a finished project frees a slot without losing anything.
Collaborators are people with a seat on a board. A read-only share link does not use a collaborator slot, however many people open it — that is the whole reason the read-only link exists.
Creating a board is refused with a message naming your plan, your limit and what you are using, so you can see whether to archive something or move up a tier. Nothing already on the platform stops working.
