| Output | Technical diagrams and markdown design documents on an infinite canvas | Shared murals: sticky notes, tables, mind maps and diagrams on an infinite canvas; exports as PDF, PNG, PPT, zipped HTML and CSV |
| API | Yes, a REST API for files, folders and diagrams, with usage-based monthly calls on paid plans, plus an MCP server | Yes, a public REST API with an OpenAPI spec, plus an official MCP server in public preview on paid plans |
| Hosting | Cloud web app; Enterprise offers flexible deployments | Not stated |
| What it makes | Architecture, cloud, sequence, flow chart, entity relationship and BPMN diagrams on an infinite canvas, next to markdown notes in the same file | Shared murals on an infinite canvas: sticky notes, tables, mind maps and diagrams, with facilitation built around them through timers, voting and a private mode for independent ideation |
| Templates and styling | Templates, AI presets, team style presets, references and naming rules that ground generated diagrams in a team's conventions; more than 3,000 tech icons, plus 20 custom icons on Starter and 100 on Business | An extensive template library, with LUMA frameworks added from the Business plan. Private rooms come with Team+, confidential rooms and multiple workspaces with Enterprise |
| Diagramming | Diagram-as-code for flow charts, ERDs, cloud architecture, sequence and BPMN diagrams with automatic layout, plus a visual editor for placing and styling elements by hand | Mapping and diagramming on every plan: shapes and connectors that attach to sticky notes, connector points for building diagrams and mind maps, and a content library that saves shapes and diagrams for reuse. Templates cover process flowcharts, workflow, data flow, swimlane and AWS architecture diagrams, and Mural AI can draft a flowchart as shapes, connectors and placeholder text |
| Collaboration and facilitation | Real-time collaboration, commenting and tagging on every plan | Facilitation tools on every plan, the free one included: summon and take control, timer, anonymous voting, private mode, laser pointer, hide and reveal, outline with instructions, facilitator lock and celebrate, plus real-time reactions.

| Export and sharing | Export to PDF, PNG, SVG and markdown, embeddable canvas figures, and integrations with GitHub, Notion, Confluence and VS Code | A mural downloads from the canvas, and Mural's help centre lists PDF, PNG, PPT, zipped HTML with data files, and CSV for sticky notes only; the whole mural, a selected area or the outline sections can be exported, and large files are processed rather than returned immediately. The API carries the same job as an endpoint, which queues a PDF export and keeps the file available for seven days |
| AI features | Yes, AI diagrams from a prompt, an image or a file such as Terraform or a database schema, refined by chat or by hand, plus AI documents; Eraserbot keeps codebase diagrams current as the code changes. AI credits are 3 on Free, 40 on Starter and 250 on Business | Mural AI works on session output rather than generating a board from a prompt: it clusters sticky notes by topic, generates mind maps, runs sentiment analysis across contributions and summarises ideas. It is listed from the Team+ plan |

How we check reviews
Reviews are not published yet. The form on a tool's page works and reaches us, but nothing from it appears on this site, so no score here is based on a review. The rules below are the ones that will apply once reviews go live.
Every review is read by a person before it appears. We require a working email address and use it to come back to the author, so a review has a reachable sender rather than being anonymous. We publish positive and negative reviews alike, we pay nothing and offer nothing for a review, and we accept none that was bought or incentivised.
What we cannot do is verify a purchase. There is no shop here and no account, so whether the author really used the tool rests on what they tell us, plus the plausibility of what they write. We say so rather than implying a check that does not exist.
A vendor cannot have a review removed, cannot buy one, and cannot have one changed. Paid placement and a paid listing have no effect on which reviews appear or on any score.
