Lucidchart is an intelligent diagramming application with data visualization and collaboration features. It’s designed to support teams and businesses as they improve and visualize processes and systems.

Why I picked Lucidchart: It's very easy to build any type of flowchart, including process maps, data flowcharts, BPMN diagrams, entity relationship diagrams, swimlane flowcharts, cross-functional flowcharts, and hundreds more. Users can also import data to generate visuals automatically.

Several features, like comments, tasks, sharing, revision history, and embedding, make collaboration simpler and easier for remote and hybrid teams. Its intuitive and clear interface makes navigating Lucidchart really easy. Lucidchart has a diverse set of features and capabilities, so it includes “Feature Find,” which allows users to quickly search for any feature or tool they’re looking for.

Miro serves as a collaborative online whiteboard platform, recognized for its versatility across over 1,000 templates including flowcharts, mind maps, Kanban boards, and more. 

Why I picked Miro: Miro's platform stands out for its ability to merge various forms of idea expression, from uploading and expanding on existing charts to incorporating diverse elements like images and videos into flowcharts. The platform also promotes interactive team collaboration through tools for voting, stickies, and comments, ensuring that teams can communicate and ideas can be refined in real-time.

Miro's infinite canvas also allows for the unbounded mapping of concepts, while the TalkTrack feature supports asynchronous communication by enabling video explanations of process maps. Additionally, integration with key project management tools like Notion and Asana embeds Miro's functionalities directly into workflows, making collaboration accessible and straightforward.

Miro Standout Features & Integrations

Features include live cursors that can help you see what others are working on, quick diagramming tools, the ability to bring everyone to your location on the canvas whenever you are leading a brainstorming session, a dependencies app that can sort dependencies between tasks on different teams and specific to each task, and annotations that can serve as a starting point for a conversation in its in-app chat.

Integrations include a whole suite of tools, including Zoom, Figma, Asana, Microsoft Teams, Monday.com, Confluence, Jira, Slack, Google Drive, Box, Airtable, Notion, Azure, and Webex. Some integrations are limited to paid plans only.

FigJam is an online diagramming tool that's part of the Figma family. It's designed to make brainstorming and collaboration super easy, especially for teams that need to create flowcharts.

Why I picked FigJam: I included FigJam in this list because their flowchart tool is easy to use and doesn't require a lot of training to quickly create flowcharts. You can get started even faster using one of their 300+ ready-to-use templates, or you can just drag-and-drop elements onto a clean whiteboard to start.

What I really appreciate, though, are FigJam's collaboration features. You can invite your team to work on a flowchart with you, and you can see their changes in real-time. It's like you're all in the same room, even if you're miles apart.

FigJam Standout Features & Integrations

Features include shapes and connectors that easily snap to the grid, real-time collaboration features, and numerous templates for the flowcharts you'll want to whip up, including organization charts, flow charts, swimlane diagrams, and entity relationship diagrams. You can also use their color picker to make your flow charts match your corporate branding too.

Integrations are available with Asana, Dropbox, Figma, Google Drive, Microsoft Teams, Notion, Slack, Trello, and numerous tools for prototyping, user testing, and developer handoff.

Design custom stencils, arrange and format diagrams of any complexity using revamped side panels, format and order position tools for professional-looking flowcharts, create a dynamic chart that can change in visual appearance based on external data source files, and more.

ConceptDraw Diagram’s asset organization is superb, including organizing thousands of images in contextual groups, object formatting and more. Therefore, they scored quite highly in our Features and Functionality evaluation criteria, where graphical elements, template options, and exporting flexibility reign supreme.

Integrations listed include the ability to import and export to the Visio file format. That’s it. In fact, they have a whole section denouncing the need for further integrations. See below for more details.

While ConceptDraw Diagram considers itself;f a “toolbelt” with features like INGYRE technology, intelligent topics, smart inputs and outputs, live Objects, ConceptDraw Solutions, dashboards, and dynamic presentations, they don’t play well with third-party software outside of their own app. This is the biggest con of the program.

ConceptDraw Diagram starts at $199 and has a free 21-day trial.

VP Online Diagrams lets you drag and click to build shapes and lines into a flowchart with an alignment guide to snap everything into place. A spreadsheet-like editor tracks and interprets your data into a visual representation and the smart dashboard lets you glean valuable insights from your work.

VP Online Diagrams finds its stride between the evaluation criteria for Features and f=Functionality and that of Usability. Tutorial videos and products will help you get started running and the free version means you can experiment before you commit. They have many different diagramming and planning tools, a variety that will work well for anyone managing different teams with different requirements.

Some of the visual elements of the diagrams and the app UI could look a little nicer. Diagrams and output docs could use a bit more polish, particularly in color settings. But overall, this is not a major drawback – just something to be considered for anyone with a draw to aesthetics.

Integrations mentioned include Eclipse, VisualStudioes, and Net Bean. You can output and share diagrams via formats like PNG, JPG, GIF, SVG and PDF.

VisualParadigm online starts from $4/month and has a free version.

Gliffy diagram and flowchart software is a drag-and-drop based diagram building that lets you sketch and share your flowchart ideas with little to no fuss. Templates and themes are available for time-saving starting points and the ability to preserve and track changes will make sure you never lose something important.

Gliffy nails many of the requirements we have in the evaluation criteria for features and functionality: Intuitive interface, including for object importing; shapes conveniently snap to grid; revisions can be rolled back in the event of an error, and it has easy editing and sharing capabilities.

A broader color customization pallet would have helped the charts tell a better data story, particularly in flowcharts with a lot going on visually. Furthermore, the software was a little buggy in the Google Chrome browser. Minor complaints for an otherwise solid tool.

Gliffy software integrates with many other apps, including WordPress, Jira Software and Jira Service Desk, Lucidchart, Atlassian Confluence, Bitium, and Nuclino.

Draw.io is a free, browser-hosted app for easy, intuitive chart building online. Because it’s online (though it can be used offline too), it’s simple to boot up and get started creating on a moment’s notice. Features include drag and drop functionality, a library of available shapes, plenty of templates, importing/exporting various formats, and more.

Obviously, being free to use, Draw.io ranks highly in our evaluation criteria for value for price. Although it may seem sot of features compared to its for-pay counterparts, Draw.io is great for small teams with smaller budgets or those who might only need flowcharting software on occasion.

Draw.io integrates with many popular apps like Google Drive, Google Docs, Dropbox, Chrome, Confluence Server/Cloud, JIRA Server/Cloud, Github, Gitlab,and OneDrive.

A few cons and critiques to note: The browser version requires Chrome to work; the app could use more shapes and templates to choose from; positioning the shapes could be a bit finicky and the “snap to place” was clumsy.

Draw.io is free to use online.

Pick between the desktop edition or the online edition, depending on your use case needs. They have quick-start diagram templates for over 70 different diagram types (and over 4,500 templates overall), intelligent automatic formatting, over 34,000 symbols, collaboration online or behind a firewall, draw and print architectural and engineering diagrams to scale, and more.

SmartDraw is a robust diagramming tool that speaks to all of my evaluation criteria for Features & Functionality, particularly the easy of drawing tools, many different templates to choose from, and ease of use so fair that even beginners can jump right in.

Any SmartDraw drawing can be inserted into Word, Excel, PowerPoint as well as Google Docs and Sheets. The app easily integrates with Microsoft, Google, Confluence, Jira, WordPress, Dropbox, Trello, and Box.

The app was a little finicky, some progress saving issues resulted in lost work and the software has a tendency to crash on top of that. I would recommend working in the cloud to instigate auto-saving in order to combat these issues.

Smartdraw starts from $5.95/user/month and has a free trial.

Have you ever tried using other diagramming tools that produce static images for your software architecture and found it inadequate for anything past the most basic designs? Terrastruct is the answer to that problem—it's a specialized flowchart software that helps you plan and document software designs through a diagramming tool in software architecture use cases.

Terrastruct takes a unique approach by letting you drag and drop to create diagrams that let you layer your models, so that viewers can go up and down levels of abstraction. It lets you define scenarios to capture how your design behaves under different conditions or edge cases.

In terms of integrations that help you make this diagramming tool work with your dev tools, Terrastruct lets you collaborate with your teammates, and integrates into your codebase. It currently offers integrations with Google Drive and Confluence (and there's more coming soon). You can also export as a PPT to present to colleagues in Powerpoint.

If what you're designing has any complexity and the diagrams from other tools end up either too messy or you're forced to oversimplify, I'd definitely suggest givng Terrastruct a try.

Terrastruct is free to use for up to 10 seats.

Cacoo is an online diagramming tool by Nulab, where you can collaborate on wireframes, flowcharts, and more.

Edit, track changes, and collaborate on flowcharts that you design and update with easy sharing links and embed links designed to make collaboration simple and intuitive. Keep team assets organized with shared project folders, save work directly in Cacoo, monitor project status with activity notifications, and more.

Cacoo is quite easy to learn and navigate, grating it high scores in the evaluation criteria sections for usability and UX. It’s both nice to look at and intuitive to figure out, even for those who are not super tech-savvy. The wealth of available integrations makes it a cince to adapt into your regularly established workflow, too.

Integrations listed include Google Drive and Google Docs, Typetalk, AWS, Adobe Creative Cloud, Slack, Dropbox, Visio, and Box. They also offer a “suggestion box” for ideas of what app they should implement integration with in the future.

Screen space can be a minor challenge to navigate, like the clunky zoom-in function, for example. However, this is a minor critique given what else the software has to offer. A few more things you might want to watch out for include the inability to save to PDF formats and the shaky responsiveness of the software on some mobile devices.

Cacoo starts from $5/user/month and has a free 14-day trial.
