Free Flowchart Maker Online: Top 8 Options Compared (2026)
Compare the best free online flowchart makers in 2026. Honest breakdown of free tiers, key features, and which tool fits your workflow.
Free flowchart tools have improved dramatically over the past few years. You no longer need an expensive license to create professional-looking diagrams—the question is which free tool actually fits your workflow without hitting limits at the worst moment.
This guide compares eight free online flowchart makers, with honest assessments of what each tool's free tier actually gives you and where it cuts off. Pricing and feature information is accurate as of early 2026.
What to look for in a free flowchart tool
Before comparing tools, it helps to know which limitations matter most:
Shape and template libraries. A generous free tier gives you enough shapes and templates to cover common use cases—flowcharts, process maps, org charts—without forcing an upgrade.
Export options. Some tools lock PDF or SVG export behind paid plans. If you need to share outside the tool, check this before committing.
Collaboration. Many free tiers allow only one user or limit real-time editing. For team use, check if simultaneous editing is available.
Storage limits. Free tiers often cap the number of diagrams or boards you can create. If you use flowcharts regularly, this adds up.
AI features. A growing number of tools now offer AI-assisted generation. This can dramatically cut the time spent on routine diagrams.
The 8 best free flowchart makers in 2026
1. Flowova
Flowova's free tier is built around AI generation, which sets it apart from every other tool on this list. Rather than starting with a blank canvas, you describe the process and the AI builds the flowchart for you.

Key features:
- Large template library including flowchart and diagram templates

Pricing: Free tier available. Canva Pro at $15/month per user.
4. Google Drawings
Google Drawings is the simplest tool on this list—it's a basic diagramming surface built into Google Workspace. If you already use Google Docs, Sheets, or Slides, Drawings is already available to you at no extra cost.
Key features:
- Completely free with a Google account
- Embedded directly into Google Workspace

Best for: Quick, informal diagrams when you're already working in Google Docs and don't need specialized diagram features. Not suitable for complex flowcharts.
Pricing: Free with a Google account.
5. Lucidchart
Lucidchart is a professional diagramming tool with a limited free tier. The tool itself is capable, but the free tier is one of the more restrictive on this list.
Key features:
- Professional-grade diagramming with a large shape library
- Real-time collaboration
- Extensive integrations (Google Workspace, Microsoft 365, Atlassian, Slack)
- Good template library
Free tier limits:
- Maximum of 3 active documents
- Up to 60 objects per document
- Limited shape libraries
- No Visio import/export
- Collaboration features limited on free
Best for: Users who want to evaluate Lucidchart before committing. The 60-object limit makes it inadequate for anything beyond simple diagrams in practice.
Pricing: Free tier (limited). Individual plan at $9/month. Team plans from $10/user/month.
6. Miro
Miro is a collaborative whiteboard platform that includes diagramming as one of its use cases. The free tier gives you functional boards but limits how many you can create.
Key features:
- Infinite canvas for open-ended brainstorming

Free tier limits:
- Maximum of 3 editable boards
- Access to basic templates only

Pricing: Free tier (3 boards). Paid plans from $8/user/month.
7. Figma / FigJam
FigJam is Figma's collaborative whiteboard product. If your team already uses Figma for design, FigJam integrates tightly with those workflows.

- Limited template access
- Advanced plugins and features require paid plan
Best for: Design and product teams already using Figma who want a connected whiteboard tool. For pure flowchart creation, other tools are more efficient.
Pricing: Free tier (3 files). Figma Professional at $15/user/month (includes FigJam).
8. Creately
Creately positions itself as a visual workspace platform with diagramming at its core. The free tier exists but is notably limited.
Key features:
- Data-linked diagrams that connect to external data sources
- Project management and workspace features beyond diagramming
- Good template library for flowcharts, org charts, and process maps
- Real-time collaboration
Free tier limits:
- 5 diagrams maximum

Choose Canva if you need diagrams that look visually polished and you're not creating complex technical flowcharts.
Choose Google Drawings if you're already in Google Workspace and need something quick without installing or signing up for anything extra.
Choose Miro or FigJam if your flowcharts are part of broader team workshops or design reviews where real-time collaboration is the core need.
Choose Lucidchart or Creately to evaluate if you're considering paid plans—their free tiers are limited but give a sense of the product.
Common mistakes when picking a free flowchart tool
Ignoring document limits. Tools like Lucidchart (3 docs) and Creately (5 diagrams) sound free until you hit the cap a week in. Check the actual limits before committing.
Overlooking export restrictions. Some tools lock PDF or SVG export to paid plans. If you share flowcharts with stakeholders who need quality exports, test this before you invest time building diagrams.
Choosing based on interface alone. A clean interface matters, but check whether the free tier provides the shapes and templates for your specific diagram type. A beautiful tool with missing process flow shapes won't help.
Ignoring offline access. If you travel or work in areas with unreliable connectivity, only draw.io offers a functional desktop offline mode at no cost.
Try Flowova for free
If your goal is to create flowcharts quickly rather than manually building them node-by-node, start with Flowova. Describe your process in plain text and the AI generates a structured flowchart—no blank canvas, no manual layout. The free tier lets you test AI generation before committing to a paid plan.
