Lucidchart is a popular flowchart, system diagram, and process map platform. It's used daily by companies and schools to explain and document complex tasks.
Lucid Software was the 12th most-used enterprise application in Okta's 2024 Businesses at Work report, showing the widespread usage of these diagrams. As more teams use visual tools to plan and communicate, the diagramming software industry is rising rapidly, from 1.0 billion US dollars in 2024 to 1.12 billion in 2025.
Growth is excellent, but it highlights a common problem. Teams reach Lucidchart's free plan limit as they create more diagrams. It may limit the number of documents they may save or disable export and collaboration features.
People start looking for a Lucidchart alternative that offers more freedom without a high price tag. Some want a free, powerful, and easy-to-use Lucidchart alternative.
The goal of this article is simple. We'll look at the best free Lucidchart alternative. We'll focus on tools with great diagramming, real-time collaboration, and AI assistance.
Why Users Look for a Lucidchart Alternative?
Lucidchart is a well-developed tool, but the free version has several limitations, which can be annoying over time. The most significant problem is the limit of the number of documents and objects you want to create.
A team that starts to develop one process map, one system diagram, and one org chart already starts to feel crowded. When you want to add more diagrams, you are soon limited and have to remove some of the older work or upgrade.
The free version restricts the export options and collaboration. Editing can be done by only a few teammates at the same time, and advanced PDF and SVG output formats can be locked. Lucidchart can hardly be considered a long-term workspace for a small business, a school, and side projects.
Enterprise teams have a different issue. They are usually required to have the flexibility of pricing, diagramming, templates, AI support, and open collaboration.
Meanwhile, an increasing number of users want online diagrams, real-time co-edits, and importing and export in various formats. Remote working teams require tools that can operate with flowcharts, mind maps, and architecture diagrams without any complications. All these factors are making people seek a more open Lucidchart alternative which fits into their way of working better.
Best Free Lucidchart Alternatives in 2025
There are some good online Lucidchart alternatives that facilitate teamwork. You can choose the best one based on your needs because they all have their own style and strengths.
Boardmix
Boardmix is the first tool to think about because it has diagramming, whiteboarding, and AI all in one platform. A large graphics library lets you make flowcharts, UML diagrams, network diagrams, and system architecture plans.
A lot of people can work on the same board at the same time, and the canvas feels light and responsive. You can quickly summarise a complex board or turn plain text into an organized diagram with the help of AI.
Draw.io (diagrams.net)
The free drawing tool Draw.io has been around for a long time. It has an easy-to-use drag-and-drop interface, a good library of shapes, and quick export options for PNG, JPEG, and SVG files. Diagrams can be kept on your computer, in Google Drive, or in OneDrive. It's easy to use and is not overloaded with features, so it's a good choice for everyday diagrams.
Miro
Miro is best known as a digital whiteboard, but it can also be used to make diagrams. It comes with templates for mind maps, flowcharts, and customer journey maps, and it works with a lot of different tools, such as Jira, Slack, and Google Workspace.
With the free plan, you can only edit a certain number of boards. However, you can use sticky notes, shapes, and connectors together on those boards to make flexible diagrams that you can use with other workshop content.
FigJam
FigJam is created by Figma and is mostly used by product and design teams. Stamps, sticky notes, and hand-drawn shapes make it playful. While getting comments from your team, you can create flows, wireframes, and simple diagrams.
It's not as good for making very formal technical diagrams, but it's great for brainstorming and making user journey maps when you want a light atmosphere in the workshop.

Boardmix also comes with a huge collection of free templates. It saves a lot of time because you can start with templates that are already made for process maps, project plans, user journey maps, and technical diagrams. It's also easy to import and export.
You can add images or files and then save your work as a PNG, PDF, SVG, or other file type that can be shared or printed. AI gives you even more power by letting you make charts from text, reorganise messy diagrams, or improve the text inside shapes.
Boardmix real-time collaboration is lighter and smoother than many older tools. The cursor moves smoothly, comments are easy to follow, and boards load fast even when they have a lot of content. Teams, students, and freelancers can join from almost any device since it all runs in the browser. This mix of flexibility, templates, AI assistance, and performance is what makes Boardmix such a strong Lucidchart alternative.
