Free Online Whiteboards and Diagram Tools
Which online whiteboards and diagram tools a startup team can use for free today, how many boards or objects the free plan allows, what collaboration it includes, whether a card is needed and what the first paid plan costs, read from each tool's own page.
Free allowances read on each provider's own pages, all checked on or after . Whiteboard tools change their free plans from time to time: confirm the terms on the tool's page before your team builds its boards there.
Whiteboard and diagram tools a startup team can use for free today include Miro (3 editable boards, unlimited members), Excalidraw (Free forever, full editor), FigJam (Free Starter plan, FigJam included), Lucidchart (3 editable documents, 75 shapes each), and Lucidspark (3 editable boards, freehand drawing). Each of the 11 free plans below links to the tool's page that states it, with its main limit, what collaboration it allows, whether a card is needed and what the first paid plan costs.
Whiteboards are where a remote team plans, maps a product and runs a retro; diagram tools draw the architecture and the flows. Most of them have a free plan, and a few open-source ones are free with no sign-up at all.
The headline rarely tells you how far it goes. A free plan can keep only 3 boards editable, cap the objects or shapes on a board, or ration AI features. Each tool below shows what is free, its main limit, what collaboration it allows, whether a card is needed and what the first paid plan costs, quoted from the tool's own page with the date we read it.
Which tools we picked and the order they appear in are our editorial choices; the terms are the providers'. Some of these providers pay us a referral commission when someone signs up through our link: those links are labeled, and they play no part in which tools are listed or where.

Compare the top options
How this comparison is built
The list covers online whiteboards and diagram tools a founder can use for free today without applying to a program. The order and the "best for" notes are our editorial reading of each tool's terms. Every term comes from the tool's own pricing or help page on the date shown, never from a third-party list; follow each link for the full conditions. A cap on editable boards, members or exports can matter more than the headline, so the comparison quotes them wherever the tool states them. Some of these tools pay StartupPerks a referral commission, and their links are labeled as referral links; that decides neither whether nor where a tool appears, and no tool pays for a placement on this page.
