Free Visio alternative

    Last updated November 2, 2026

    Microsoft Visio is a diagram application for the desktop and the web, with large stencil libraries and .vsdx files. FlowSimp is a lighter browser flowchart maker and whiteboard that is completely free to use — no sign-up required. It draws the diagram. It does not open a Visio file.

    How does FlowSimp compare with Visio?

    Visio is the tool you use when the file format and the stencil set matter. FlowSimp is the tool you use when you want a flowchart in a browser tab without installing an application or creating an account. Paid Visio plans exist. Their prices change, so they are not listed here.

    How do you switch a flowchart to FlowSimp?

    1. Leave the .vsdx file where it is. FlowSimp cannot open it, and it cannot write one back.
    2. Copy the steps into a list, or into a Mermaid flowchart if you already have that text. Paste it on text to flowchart.
    3. Or start from a template, such as the expense process or the org chart, and replace the sample words.
    4. Export PNG or SVG for a document. Use a read-only share link when someone only needs to view the diagram.

    What should you not expect?

    Do not expect Visio stencils, floor plans, or a round trip through .vsdx. FlowSimp’s flowchart shapes are rectangle, rounded rectangle, diamond, and circle. Network mode adds a router, switch, server, firewall, cloud, and workstation. That is the set. If the drawing depends on a Visio stencil, keep it in Visio.
