For a free Lucidchart alternative, compare Boardmix for collaborative diagramming, draw.io for file-based diagrams, Miro for workshops and FigJam for informal team mapping. Each serves a different need, and most hosted free plans have limits. If your task is to explain a process with teammates, the Boardmix flowchart maker is one option to try with the same diagram you currently use in Lucidchart.
Lucidchart is widely used for flowcharts, system diagrams and process maps. In Okta’s 2024 Businesses at Work report, it ranked 12th among the most popular applications in the overall customer sample. That historical ranking reflects adoption among Okta customers; choosing a diagramming tool still depends on your diagrams, collaborators and budget.
As a team creates more diagrams, Lucidchart’s free-plan limits on editable documents, objects and premium features can affect the work it can maintain. Check the current plan and the collaborators’ access before deciding whether to upgrade or move. Common image exports and real-time sharing are available on Free; they should not be treated as entirely paywalled features.
An alternative may make sense when its free allowance, editing model or collaboration style fits your work better. Compare the total cost and migration effort as well as ease of use; “free” does not necessarily mean unlimited boards, private sharing or AI usage.
Use a small test set: one process map, one system diagram and one organizational chart. Check whether you can keep each editable, invite a colleague and export the result at a readable size. Use the same test when comparing Lucidchart with the four alternatives below.
Why Do Users Look for a Lucidchart Alternative?
Lucidchart’s Free plan provides a way to make diagrams with a limited number of editable documents and objects, while premium libraries and other advanced features require an eligible plan. These restrictions matter when your diagrams become larger or you need to maintain several of them at once.
A process map, a system diagram and an organizational chart already use three editable documents. When a team needs additional active documents, it should check which ones remain editable and whether a paid plan is justified. Keep original files and reference copies when comparing alternatives; deleting older work is not a required first step.
Lucid’s export help lists PDF, PNG, JPEG and SVG export for Free accounts; exporting a Visio file requires a paid Individual, Team or Enterprise account. Collaboration also depends on permissions and each person’s plan: a free collaborator may be unable to edit a document that exceeds their available objects or uses paid features. Test the actual diagram and invitees instead of assuming all sharing or useful exports are unavailable.
Enterprise teams may also need centralized administration, predictable licensing, suitable templates, AI allowances and a clear way to control internal and external access. These requirements deserve a separate plan comparison, even when a small free workspace is enough for an individual’s diagrams.
Remote teams often need flowcharts, mind maps and architecture diagrams that colleagues can edit together and share in usable formats. Check importing and exporting separately: bringing in a picture of a diagram is useful for reference, but it does not necessarily preserve editable shapes, connectors, comments or permissions.
Free Lucidchart Alternatives to Compare
The following four alternatives cover collaborative canvases and more traditional diagram files. Their strengths differ, so select one around the diagrams you need, the people editing them and what the free plan actually includes.
Boardmix
Boardmix combines diagramming, collaborative whiteboarding and AI-assisted creation in one workspace. Its graphics library can be used for flowcharts, UML diagrams, network diagrams and system architecture plans, with notes and supporting material placed nearby.
Teammates can edit a shared board according to their permissions. Available AI actions can draft a flowchart or mind map from supplied text and help summarize selected material; review the result for missing steps or incorrect assumptions. AI access and usage depend on the plan and available credits, and responsiveness should be checked on your own diagrams and devices.
draw.io (diagrams.net)
draw.io is a free diagram editor with a drag-and-drop canvas, shape libraries and export options including PNG, JPEG and SVG. Diagrams can be saved locally or with supported storage services such as Google Drive and OneDrive. Keep the editable diagram file as well as any exported image. It is a useful option for everyday diagrams when file control matters more than a workshop-style canvas.
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.
Miro Free allows editing on the team’s three most recently created boards; other boards become view-only. On editable boards, sticky notes, shapes and connectors can sit beside other workshop content. Check sharing and export requirements before making the free team workspace your long-term home for process documentation.
FigJam
FigJam is Figma’s collaborative whiteboard, commonly used for product and design discussions. Stamps, sticky notes and freehand drawing support quick flows, rough interface sketches and simple diagrams while teammates leave comments.
It can suit brainstorming and user journey mapping in an informal workshop. If your work depends on strict technical notation, detailed data-linked diagrams or a particular interchange format, compare those needs with a dedicated diagramming tool before choosing it.
When to Consider Boardmix for Diagramming

Boardmix combines diagrams and collaborative whiteboarding in one workspace. It may be useful when a project needs several related visuals, but compare the exact tools and account limits for your work.
A team can organize mind maps, architecture diagrams, UML diagrams, network and infrastructure maps, and flowcharts in the same Boardmix workspace. Keeping these related visuals close together can help product and technical teams explain different parts of a project without repeatedly rebuilding the context.
Boardmix templates provide starting points for process maps, project plans, user journey maps and technical diagrams. Choose a template that fits your task, then check its access and the account’s limits. For existing work, verify the specific import format and the export quality you need rather than assuming every file transfers in the same way.
You can place images or supported files on a board and export work in formats such as PNG, PDF and SVG. The plan affects export quality and other options. Available AI tools can draft diagrams from text, summarize supplied material or improve an explanation; you still need to inspect the layout, labels and logic rather than assume an existing complex diagram will be reorganized correctly.
Try the same process map with a colleague on the devices they normally use. Check small text, connector labels, loading and editing, then export it and inspect the file at its intended size. Include one changed decision branch so you can see whether the result is genuinely editable and easy to maintain.
Lucidchart vs Boardmix: A Quick Comparison
Use the following checks to compare the plan you would actually use. The table does not assume that either free tier is unlimited or that a feature available on a paid plan is included for every collaborator.
| Check | Lucidchart | Boardmix |
|---|---|---|
| Free access | 3 editable documents; see current document and feature limits | 3 editable boards, 100 objects per board, 1 GB storage |
| Diagramming | Test the required symbols, connectors, and export formats | Test the required symbols, connectors, and export formats |
| Collaboration | Confirm editing and sharing permissions for the plan | Confirm editing and sharing permissions for the plan |
| AI | Check the selected plan’s available actions and allowance | See Boardmix pricing for available actions and allowance |
| Large diagrams | Test the same sample on the same devices before choosing | |
The useful comparison is whether the chosen plan supports your diagrams, collaborators and export requirements. Free-plan limits apply to both products. Check whether the people you invite can edit the objects you use, and whether an exported copy preserves the detail your audience needs.
How to Move from Lucidchart to Boardmix

Start with one representative diagram before moving a library of documents. Keep the original Lucidchart version and an export for reference, then check what can remain editable in Boardmix. The steps below use a small approval flow with a request, review, approval decision and either completion or revision.
1. Create a Free Boardmix Account
Open Boardmix and register using an available sign-up method. After signing in, choose the appropriate workspace and check its plan and sharing settings. If your organization requires managed single sign-on, confirm that its administrator has configured it; do not assume that every free account includes enterprise SSO.
2. Create a New Whiteboard
Create a new board with a clear name, such as “Request approval flow.” Start with a blank canvas or a relevant template. Reserve one area for the old diagram as a reference and another for the new editable version, so reviewers can compare them without confusing the two.
3. Choose Shapes and Templates from the Graphics Library
Open the graphics panel, choose suitable flowchart symbols, UML shapes or network icons, and connect them with arrows. For the approval example, show request submission, review, an approval decision, completion and a revision path. If AI flowchart drafting is available in your plan, supply these exact steps as a starting prompt and verify both decision branches before relying on the result.
4. Bring in the Original as a Reference and Rebuild What Must Be Editable
Export the Lucidchart diagram in a format you can use, such as PNG or PDF, and bring it into Boardmix as a visual reference. An imported image or PDF does not automatically become editable process shapes and connectors. Recreate the parts you need to maintain with native shapes, then compare labels, arrows, decision branches and linked instructions with the original. Keep comments, notes and other material separately if they are absent from the export; retain the original file until the rebuilt diagram has been checked.
5. Invite Your Team and Check the Handoff
Use the sharing controls to invite teammates with the permissions they need. Confirm that an intended editor can move a shape and change a label, while a reviewer can leave the expected feedback. Walk through the approval and revision paths together, resolve discrepancies and keep a checked copy of the supporting instructions. Once this pilot works for the team, decide which additional diagrams are worth moving and which should remain in their existing tool.
Choose with a Real Diagram
Lucidchart may remain a good fit when its diagramming features and access controls meet your needs. Its free-plan limits can prompt a review as the number or complexity of active documents grows, but common image exports and real-time collaboration are available; compare the actual restrictions rather than assuming the free version cannot support useful work.
Boardmix is one alternative for keeping flowcharts, UML diagrams, architecture diagrams, and mind maps in a shared workspace. Boardmix Free includes three editable boards, up to 100 objects per board, and 1 GB of storage. AI access and usage allowances vary by plan; see Boardmix pricing.
For students and small teams, a useful next step is to try Boardmix with one real diagram and a collaborator. Compare editability, permissions, export quality and total cost before committing. Keep the original project available until the new version is complete and usable by the people who need it.
