draw.io vs Lucidchart: when free is enough
draw.io and Lucidchart draw most of the same diagrams. The big difference is the business model. draw.io is free and open source. Lucidchart is a paid suite with a limited free plan. This page shows where the paid suite earns its price, and where it does not.
Wavelength is a voice to diagram tool that turns a spoken process or a call transcript into an editable flowchart. It imports and exports draw.io files, so it works next to either tool.
We checked drawio.com and Lucid's pricing page on October 6, 2026.
The short answer
- Choose draw.io when cost matters, when you want your files in your own storage, or when you diagram inside Confluence, GitHub, or VS Code.
- Choose Lucidchart when you want premium templates, data linking, version history, and admin controls in one product with support.

Where draw.io wins
Cost. It is free, with no seat count and no document limit. For a team of 20, that saves the $2,400 a year that Lucidchart Team would cost on list price.
File control. The draw.io site says you can store your data where you want, and that they cannot access it. For regulated teams, that can end a long security review before it starts.
Developer workflow. draw.io lists a VS Code extension and GitHub integration. A diagram can live in the same repository as the code it describes.
Long life. The draw.io site says that files from 2005 still open in today's app. Anyone can open a .drawio file without a license.
Where Lucidchart wins
Polish and templates. Lucidchart has a large library of premium templates and shape packs, and its editor is smooth for people who are not diagram experts.
Data linking and automation. Lucid lists data linking on every plan and advanced data and automation on Enterprise. You can drive a diagram from a spreadsheet or another data source.
Team features. Team adds revision history with versioning and password protected publishing. Enterprise adds SAML, sharing restrictions, and team hubs.
One vendor. Procurement, support, and admin sit with one company that sells to large businesses.
What both tools have in common
In both tools, a person draws every box and every arrow. That is fine when the person knows the process well and has the time. It is slow when the process lives in other people's heads. Then the drawing waits for interviews, notes, and a second meeting to check the result.
Where Wavelength fits
Wavelength builds the first draft for you. You describe the process out loud, or paste a call transcript, and it draws the flow. Then you send it to draw.io if you want to finish it there. Wavelength exports to draw.io on every plan, including Free, and it imports .drawio and .xml files from draw.io.
So a practical setup for a cost-aware team is:
- Capture the process in Wavelength during the call or the workshop.
- Confirm the dashed, AI-inferred links with the people in the room.
- Export to draw.io for pixel-level layout, or keep it in Wavelength and share a live link.
If you are moving away from Lucidchart, export your documents as Visio .vsdx files. Both draw.io and Wavelength can import them. Wavelength can import up to 50 files at the same time. See how to switch from Lucidchart.
Moving from Lucidchart to draw.io
The move has three steps. First, export each Lucidchart document as Visio .vsdx. Lucid's help center says this needs an Individual, Team, or Enterprise account, and that you export one document at a time. Second, open each .vsdx file in draw.io, or import it into a blank diagram. Third, check the result. Custom shapes and some connector styles can change during any Visio round trip, so look at each diagram before you delete the original.
Do the diagrams your team uses every week first. Leave old diagrams in Lucidchart until someone needs them. When your Lucidchart renewal date comes, you will know which diagrams matter.
Our verdict
If the only reason you pay for Lucidchart is to draw flowcharts and simple diagrams, draw.io is enough for most teams, and it is free. If your team uses Lucidchart's data linking, its integrations, or its enterprise controls every week, those are worth paying for, and draw.io does not match them in one product. The fair test is simple. List the Lucidchart features your team used last month. If the list is short, try draw.io for one quarter and compare.
When Wavelength is the wrong tool
If you already know the process and you want to draw it yourself, use draw.io. It is free and faster for that job than any AI tool. Wavelength is for the part before that, when you are still learning the process from someone else. It also does not draw UML, ERD, network, or floor plan diagrams.

Common questions
Is draw.io really free?
Yes. The draw.io site says its source code is under the Apache 2.0 license, that it needs no account, and that there are no paywalls. Some integrations, such as the Confluence app, are sold through the Atlassian marketplace, so check those separately.
Can draw.io open Lucidchart files?
Not the native Lucidchart format. Export from Lucidchart as Visio .vsdx first. Visio export needs a Lucidchart Individual, Team, or Enterprise account.
Is draw.io safe for confidential diagrams?
The draw.io site says you store your data where you want and that they cannot access it. Your own storage choice decides who can read the files.
Does Lucidchart have features draw.io does not?
Yes. Lucid lists data linking, premium templates, revision history with versioning on Team, and SAML, sharing restrictions, and a Salesforce integration on Enterprise.
Can Wavelength export to draw.io?
Yes. Every Wavelength plan, including Free, exports a flow to draw.io. Wavelength also imports .drawio and .xml files from draw.io.
Every new account starts with 7 days of Pro. No card needed.
