02Pricing compared
draw.io’s Free plan costs $0 and includes unlimited diagrams and users, with no account required. Its paid Cloud options are for Confluence and Jira: the pricing details list free access for up to 10 users and paid tiers starting at $5 or $20, depending on product or tier. Data Center starts at $6,000 per year.
Overleaf also has a free plan, but it limits projects to one collaborator. Student costs $8.25 per month with annual billing or $13 month to month. Standard is $16.75 per month annually or $25 monthly; Pro is $33.25 annually or $45 monthly. So for basic diagramming, draw.io is the cheaper fit. Overleaf’s paid plans buy more collaborators and other writing features, not diagramming.
03Features and depth
These products solve different problems. draw.io is for making diagrams; Overleaf is for writing formatted technical and scientific documents. They are not direct substitutes unless your project could use either a diagram or a written document.
draw.io supports shared cursors for real-time collaboration, flexible data storage, and embedding interactive diagrams in documents, wikis, or applications. It exports to SVG, PNG, and PDF, and files can remain editable. Its stated file compatibility includes loading files created in 2005 in the current app.
Overleaf combines visual and LaTeX code editors with simultaneous editing and commenting. It provides templates, citation and bibliography tools, and support for formulas, figures, and tables. The free plan allows one collaborator per project and five AI uses per day. Student and Standard allow 10 collaborators; Pro allows unlimited collaborators. AI-use allowances differ by plan, and Pro’s is subject to fair use.
04Ease of use and learning curve
draw.io is the simpler starting point if the job is a diagram: its Free Online and Desktop plan requires no account, and the listed features include editing across platforms. Teams can collaborate with shared cursors, though the published information does not spell out setup requirements for each storage option.
Overleaf says users can write visually or edit the LaTeX code directly, and that no prior LaTeX knowledge is required. That lowers the barrier, but the product is still a LaTeX editor; its learning resources cover both fundamentals and advanced topics. Choose the interface that fits the work: diagram editing in draw.io, or document writing and formatting in Overleaf.
