Cacoo is Nulab's real-time online diagramming tool for flowcharts, wireframes, and mind maps. See 2026 pricing, features, pros, cons and how it fits with…
Cacoo is the diagramming product inside Nulab Inc.'s suite of collaboration tools, sitting alongside Backlog (project management and issue tracking) and Typetalk (team chat). Nulab was founded in 2004 and is headquartered in Fukuoka, Japan, with a global user base built up over more than a decade of steady product development rather than venture-fueled rapid expansion. Cacoo itself launched in 2010 as a browser-based alternative to installed diagramming software, aimed at making flowcharts and wireframes something a whole team could co-edit rather than something one person built and emailed around.
Because Cacoo and Backlog share a parent company, organizations already using Backlog for sprints and issue tracking can bring diagramming into the same account structure, which reduces the usual friction of adopting a diagramming tool from an unrelated vendor. This is a meaningful differentiator versus standalone diagramming tools: Cacoo is designed to be one piece of a broader Nulab workflow rather than a single-purpose app.
Cacoo's headline feature is real-time multiplayer editing: multiple users can be on the same canvas simultaneously, see live cursor movement, and communicate through built-in video chat and threaded comments without switching to a separate call tool. Supported diagram types span flowcharts, wireframes and mockups, network diagrams, mind maps, organizational charts, entity-relationship diagrams, and UML models, backed by a library of templates and shape stencils.
Additional workflow features include revision history for rolling back unwanted changes, a code-to-diagram capability for generating certain diagrams from structured text, and a lightweight Kanban board for tracking related tasks alongside a diagram. Export options include PNG on the free tier, with additional formats unlocked on paid plans, and diagrams can be embedded directly into Confluence pages, Google Workspace documents, and other integrated tools.
Cacoo's Free plan supports unlimited users and six diagram sheets, along with templates, PNG export, real-time editing, video chat, and comments, making it usable for genuinely small teams rather than a stripped-down trial. The Pro and Team plans are both listed at $6 per user per month, with the Team plan adding support for organizations up to 1,000 users, dedicated onboarding training, and password-protected diagrams on top of everything in Pro, such as unlimited sheets and revision history.
Annual billing saves roughly 17 percent compared with paying monthly, and a 14-day free trial is available on any paid plan without a credit card. Larger organizations that need SAML single sign-on, SCIM provisioning, audit logging, and centralized access management can move to the custom-priced Enterprise plan, which also includes a dedicated customer success manager.
