Looking for a free flowchart maker? Start with diagrams.net when you need a free, no-sign-up editor; choose Boardmix or Creately when several people need to review a shared canvas; use Google Drawings when your work already lives in Google Drive; and treat Visio, SmartDraw, Gliffy, Lucidchart, Visme, and Visual Paradigm as bundled, free-tier, or trial options whose limits need checking. This 2026 comparison uses the same criteria for all 10 tools: access model, collaboration, templates, AI assistance, export, and the practical limit that can stop a project.
What Counts as a Free Flowchart Maker?
A flowchart maker turns a process into connected actions, decisions, inputs, and outcomes. The word free can describe four different access models:
- Free forever: the provider offers a continuing no-cost edition, often with fewer exports, storage, or advanced diagram types.
- Free tier: you can keep using the product, but files, objects, collaborators, or downloads are capped.
- Free trial: the full product is available for a limited evaluation period and then requires a subscription.
- Bundled access: the diagram tool is included only through another plan, such as Microsoft 365 or Google Workspace.
A tool can therefore be free to draw in and still be a poor fit for a team that needs private sharing, version history, editable exports, or a large process map. We reviewed provider plan and help pages on September 22, 2026. Limits and menu labels can change, so use the linked first-party page as the final check before committing data or promising a format to a client.
How We Compared Free Flowchart Makers
Each tool is judged against the same job: create a readable process, let the right people review it, and deliver it in a format the next person can use.
- Access model: free forever, free tier, trial, or bundled access?
- Creation workflow: blank canvas, template, text-to-diagram, or a mixture?
- Diagram quality: standard flowchart symbols, attached connectors, swimlanes, alignment, and readable labels?
- Collaboration: view, comment, edit, guest access, and version history on the plan being compared?
- Export and reuse: PDF, PNG, SVG, editable files, imports, and watermarks?
- Data and administration: storage location, privacy, permissions, and account requirements?
We do not rank a tool merely because it has the longest feature list. A simple editor with local storage may be the best choice for a one-off diagram, while a team may value permissions and recovery more than an AI button. The table below is a quick orientation; the product sections explain the caveat behind each label.
Features to Check Before You Choose
Before drawing a real process, test the complete path from first shape to final file:
- Start-up friction: Can a new user create a chart without a long setup or an unexpected paywall?
- Flowchart notation: Are decisions, subprocesses, inputs, documents, and swimlanes available and easy to label?
- Connector behavior: Do arrows stay attached when shapes move, and can you see the direction of every branch?
- Team review: Can a reviewer comment or edit with the intended permission, and can you recover an earlier version?
- Delivery: Does the free plan export the format and resolution your document, slide deck, or SOP requires?
- AI and templates: Are they included in the plan, and can you inspect and correct every generated node?
For privacy-sensitive or regulated workflows, check storage and administration before uploading source data. For a presentation, export a small test chart first; a watermark, rasterized text, or missing connector is easier to catch before the final review.
10 Free and Freemium Flowchart Makers (2026)
The ten entries below are kept because they cover different free and freemium jobs. Each section uses the same labels so you can compare a real workflow instead of marketing adjectives.
| Tool | Best for | Access model | Collaboration | Export or automation | Main caveat |
|---|---|---|---|---|---|
| Boardmix | Shared whiteboard workflow | Free plan | Shared editing; verify review roles | Templates; AI Flowchart on AI Starter; standard-definition export on Free | Free board, object, storage, and history caps |
| diagrams.net | Free, file-based diagramming | Free forever | Depends on storage/integration | SVG, PNG, PDF; open source | Fewer guided team-workspace features |
| Google Drawings | Simple charts in Google Drive | Bundled with Google account | Drive sharing roles | Shapes, lines, and image export | Not a dedicated flowchart product |
| Microsoft Visio | Microsoft 365 organizations | Paid or eligible bundle | Microsoft sharing and comments | Templates and Visio formats | Not universally free |
| Gliffy | Confluence documentation | Free Confluence tier; trial elsewhere | Confluence permissions | JPEG, PNG, SVG | Access is tied to Atlassian licensing |
| SmartDraw | Template-led business diagrams | Free trial | Cloud sharing and integrations | Automation and office integrations | No permanent free plan |
| Visme | Presentation-ready visuals | $0 Basic tier | Limited on Basic | Templates and design assets | Download formats and assets are plan-dependent |
| Creately | Collaborative process mapping | Free forever | Multi-user collaboration | Basic shapes/collaboration; templates and connectors vary by plan | Items, imports, storage, and export limits |
| Lucidchart | Cloud diagrams and integrations | Free tier | Real-time collaboration | Templates and integrations | Free documents and features are capped |
| Visual Paradigm | Technical and business diagrams | Personal/non-commercial free edition or trial | Cloud workspace options | Many diagram types and image/PDF export | Advanced flowchart access varies by edition |
How to read the table: “Free” describes the access model, not an unlimited feature promise. Check the provider's plan page for your region, account type, storage choice, and export requirement.
Boardmix: Best for a Shared Whiteboard Workflow
Boardmix is an online whiteboard that combines flowchart templates, standard shapes, connectors, an infinite canvas, and collaborative editing. It is a useful fit when the process map needs to sit beside notes, feedback, or other project material. The current pricing page lists a Free plan with one team workspace, three editable boards, 100 objects per board, 1 GB of storage, standard-definition export, and 10 version-history records.
Best for: Teams that want a shared canvas around the flowchart.
AI and templates: Boardmix exposes flowchart templates. Its current pricing page lists AI Flowchart under the AI Starter plan, so do not assume AI generation is included in Free; confirm the plan before drafting and review every generated branch. The separate AI flowchart generator guide covers the assisted workflow and its verification step.
Caveat: Free board, object, storage, export, and history limits are plan-specific. Test the exact workspace before migrating a large process.
diagrams.net (draw.io): Best for Free, File-Based Diagramming
diagrams.net, also called draw.io, is an open-source diagram editor that the provider describes as free forever with no sign-up required. You can store files locally or connect the editor to a storage service, then export to formats such as SVG, PNG, and PDF. It is a strong default for a one-off chart or a team that wants control of its files.
Best for: Users who want a capable free editor without a paid workspace.
Collaboration: Collaboration depends on the selected storage or integration, so test the sharing path rather than assuming every file is live-edited.
Caveat: The interface is more diagram-editor than guided workflow product. See the official draw.io site for current storage and export options.
Google Drawings: Best for Simple Charts in Google Drive
Google Drawings is a lightweight canvas available through Google Drive and Google Docs. It supports shapes, lines, text, and images, while Drive supplies sharing roles and collaborative editing. It works well for a simple process map that must live beside a Google document or presentation.
Best for: Students and teams already standardized on Google Drive.
Access: A Google account and the relevant Drive permissions are part of the workflow; it is not a separate flowchart-first free plan.
Caveat: Advanced diagram libraries, automatic layout, and flowchart-specific templates are more limited than in dedicated tools. The Google help guide documents the current drawing and sharing workflow.
Microsoft Visio: Best for Microsoft 365 Organizations
Microsoft Visio is a full diagramming product, not a universally free standalone maker. Visio Plan 1 is a paid web plan, while some Microsoft 365 commercial or education arrangements include web access; consumer Home/Personal accounts should not be assumed to include it. It remains attractive when the organization already uses Microsoft identity, OneDrive, Teams, or Visio files.
Best for: Microsoft-first organizations with an eligible license or existing Visio files.
Strengths: Professional templates, Microsoft integrations, comments, and a familiar enterprise sharing model.
Access caveat: Verify the exact account and plan in Microsoft's Visio for the web FAQ before calling it free.
Plan reference: This screenshot is retained as a visual reference; plan names and prices can change.
Gliffy: Best for Confluence Documentation
Gliffy is now most clearly positioned as a Confluence diagram app. Its current pricing page lists a free Confluence tier for up to 10 users with no time limit, while evaluations for other setups are time-limited. The app supports flowcharts and other diagrams, and the provider lists JPEG, PNG, and SVG exports.
Best for: Teams that keep process documentation in Confluence.
Collaboration: Permissions follow the Atlassian host product, which can be useful for existing Confluence teams.
Caveat: “Free” is tied to the host and user tier. Check the current Gliffy pricing page rather than treating it as a universal standalone editor.
Plan reference: The pricing screenshot below is historical context, not a promise of today's price.
SmartDraw: Best for Template-Led Business Diagrams
SmartDraw is a feature-rich diagramming product with automation, templates, and integrations with Microsoft and Google tools. Its official FAQ describes a free trial rather than a permanent free plan, so it belongs in a free-tools comparison as a trial option, not as an unlimited free service.
Best for: Users who want guided templates and are willing to evaluate a paid product.
Access: Free trial; ongoing use requires a paid subscription.
Caveat: Confirm the trial duration, storage, and export terms in the official SmartDraw FAQ.
Plan reference: The screenshot below should be rechecked before quoting a price.
Visme: Best for Presentation-Ready Flowcharts
Visme is a visual-content platform that includes flowchart layouts and design assets. Its current pricing page lists a $0 Basic tier with limited storage, templates, assets, collaboration, and AI credits; download formats and higher-resolution output vary by plan. It is a good fit when the diagram must become a polished presentation graphic.
Best for: Marketing, teaching, and presentation assets where visual styling matters.
Strengths: Templates, design controls, and visual-content features beyond a basic diagram editor.
Caveat: The free tier is useful for testing, but assets, privacy, collaboration, and downloads are limited. See the current Visme pricing page.
Plan reference: Recheck this pricing screenshot before publication.
Creately: Best for Collaborative Process Mapping
Creately combines diagramming with a shared visual workspace. Its current plans page describes a free-forever plan with basic shapes and collaboration, while limits apply to items, storage, imports, and some exports. Templates and advanced connectors vary by plan, so confirm they are included before choosing it for a complex process map.
Best for: Teams that want the process and its review context in one workspace.
Strengths: Templates, comments, connectors, and multi-user editing are central to the workflow.
Caveat: The free plan is not unlimited. Check items per workspace, imports, storage, and export formats in the Creately plans.
Plan reference: This screenshot is retained for visual context; do not infer current limits from it.
Lucidchart: Best for Cloud Diagrams and Integrations
Lucidchart is a cloud diagramming tool with templates, collaboration, and integrations. The free tier is useful for trying the editor, but document, feature, and export limits can affect a real team workflow. It is a strong candidate when the diagram needs to connect to other cloud tools and the team is comfortable with account-based storage.
Best for: Teams that value integrations and a polished cloud editor.
Collaboration: Test the exact viewer, commenter, and editor roles you need on the free tier.
Caveat: Free document and feature caps are easy to miss. Confirm current limits on the Lucidchart pricing page.
Plan reference: Recheck the pricing screenshot before quoting a limit.
Visual Paradigm: Best for Technical and Business Diagrams
Visual Paradigm Online covers flowcharts alongside UML, ER, BPMN, and other technical or business diagrams. Its official pages distinguish a free community/personal or non-commercial path from paid editions and trials; advanced diagram types and commercial use may require a different edition.
Best for: Students, educators, and technical users who need more than a basic process chart.
Strengths: Broad diagram coverage, templates, alignment tools, and image/PDF export options.
Access caveat: Verify whether your use is personal, educational, non-commercial, or paid in the Community Edition terms and the flowchart tool page.
Plan reference: The pricing screenshot below is retained for comparison only.
A Practical Boardmix Flowchart Workflow
Boardmix is one workflow option when the process needs both a diagram and a shared review space. Start with the process boundary, add one shape per action or decision, connect the sequence, and ask a reviewer to challenge missing branches. The Boardmix flowchart workspace documents standard symbols, templates, and collaboration options; verify the current Free limits before a large project.
Five-minute test: create a short approval process, invite one reviewer, move a decision node, restore an earlier version, and export the result. Record what the current plan actually permits instead of relying on a generic feature promise.

This is a reproducible workflow example, not a customer case study or a claim that one tool is universally best.
How to Choose a Free Flowchart Maker
Choose by the job the diagram must complete. For a broader software shortlist beyond this free/freemium comparison, see the best flowchart software for team collaboration guide.
- One-off personal chart: start with a no-sign-up or local-storage tool and confirm that the export opens where you need it.
- Team process review: prioritize live editing, comments, permissions, and version recovery over decorative templates.
- Microsoft or Google workplace: test the bundled tool first, then compare its export and diagram depth with a dedicated editor.
- Technical or regulated workflow: check data location, administration, audit requirements, and commercial-use terms before uploading source data.
- Presentation-ready output: export a small chart to PDF, PNG, and SVG where available; inspect text, connectors, and watermark behavior.
- AI-assisted draft: use generated content as a starting point and verify every node, branch, label, and exception manually.
Broader whiteboard and design suites such as Canva, Miro, FigJam, and Whimsical can be sensible alternatives when the flowchart is part of a workshop or visual-design project. They are not scored as dedicated flowchart-first tools here because their free limits and product scope change independently.
Run the same small process through two or three candidates. A ten-minute test exposes more than a feature list: measure setup time, connector behavior, reviewer access, recovery, and the quality of the exported file.
Free Flowchart Maker FAQs
Is there a completely free flowchart maker?
Yes. diagrams.net is presented by its provider as free forever and no-sign-up, while other products use free tiers, trials, or bundled access. “Free” does not automatically mean unlimited storage, private sharing, collaboration, or export.
Can I make a flowchart without signing up?
Some editors support local or guest creation. Cloud saving, team sharing, version history, and account-based templates usually require a sign-in. Test the whole workflow, not only the first drawing step.
Is Microsoft Visio free?
Not as a universally free standalone product. Visio has paid plans, and web access may be included with selected Microsoft 365 commercial or education arrangements. Check the account and license rather than assuming that a personal Microsoft account includes Visio.
Which tool is best for team collaboration?
Choose the tool whose free or bundled plan gives every reviewer the right role, preserves a usable history, and keeps the diagram readable after simultaneous edits. Boardmix and Creately are strong shared-canvas candidates; Microsoft, Google, Lucidchart, and Gliffy may be better when your team already uses their host ecosystem.
Can I export a free flowchart to PDF or SVG?
Often, but the answer depends on the tool and plan. diagrams.net lists SVG, PNG, and PDF export; other products may limit formats, resolution, editability, or watermarks. Export a small test chart before building a report around a promised format.
Are AI flowchart makers free?
AI may be included in a free tier, offered as limited credits, or reserved for a paid plan. Treat AI output as a draft, review the logic manually, and confirm the current credit and export rules before comparing products.
