  • Visualize the current and future state of your network

    Visualize the current and future state of your network

    Network diagrams play an essential role in illustrating the ins and outs of your network. As a network engineer or an IT professional, you’ll likely need to create network diagrams as you design, build, and troubleshoot your network or help others understand its functionality. Network mapping tools can also be used to coordinate updates and act as documentation for external communication, onboarding, troubleshooting, etc. Use our network diagram maker to ensure that your network runs smoothly and is compliant with security standards like GDPR, PCI, and SOC 2.

  • Create network diagrams according to industry standards

    Create network diagrams according to industry standards

    Build your network diagram online using standard network topology with our extensive shape libraries and intuitive interface. Gain access to hundreds of standard and industry-specific icons that make mapping all of your routers, servers, and connection types easy. You can even link data to your shapes to reflect the number of ports, IP addresses, and more. Lucidchart includes globally recognized shapes and icons for Cisco, server racks, and other vendor-neutral shapes. Or, simply import your own custom shapes, so you’ll have all the icons you need to accurately represent your network. 

  • Create a central source of truth for collaboration

    Create a central source of truth for collaboration

    Whether you’re demonstrating compliance or implementing network changes, use our network design software to create a central and single source of truth for your network. Lucidchart ensure teams always have access to the most up-to-date version of your network diagram—and its version history—to make informed decisions about your network. Our cloud-based network diagram tool works seamlessly across Mac, PC, and Linux operating systems, so you can collaborate with anyone, anywhere, anytime. Comment directly on your diagram or @mention specific collaborators to speed up and simplify the feedback process.

  • Integrate and share

    Integrate and share

    When you combine our network diagram maker with the popular apps you already use, it’s easy to share your polished network diagrams with colleagues. Lucidchart integrates seamlessly with Confluence, Jira, Slack, Microsoft Teams, and more. If we don't have a built-in integration, you can still use an embed code to add to your wiki and other platforms. Distribute your network diagram via email or a published link. Choose who can view and edit your network diagram with customizable sharing permissions.

  • Replace Visio with Lucidchart

    Replace Visio with Lucidchart

    If you’ve been using Visio to map out your network, it’s simple to make the switch to Lucidchart. Import VDX, VSD, and VSDX files and Visio stencils, both generic and custom shapes, into Lucidchart so you don’t have to start from scratch. With our export feature, you can still collaborate on network diagrams with co-workers and clients who use Visio. As the preferred network diagram maker, Lucidchart provides all the functionality that Visio offers plus a more intuitive interface, true real-time collaboration, accessibility across devices and operating systems, and data integrations—all at a lower cost.
