Your ARXML files never leave your computer

In automotive, ARXML describes confidential vehicle software — it can’t be uploaded to a random web tool. EasyARXML solves that at the architecture level: the file is read entirely in your browser and never sent anywhere. Don’t take our word for it — open your browser’s Network tab and watch. Nothing uploads.

No server round-trip No file storage No telemetry on your data

How the ARXML viewer works

01

Drop your .arxml

Drag an AUTOSAR ARXML file onto the app, or click to pick one.

02

Parsed in your browser

EasyARXML reads the file locally — components, ports and connectors — with nothing uploaded.

03

Explore the diagram

Pan, auto-arrange and read the architecture at a glance, then export it as a PDF.

Built for AUTOSAR engineers

EasyARXML was built by an automotive systems architect to fix a daily annoyance: understanding an ARXML file quickly, without firing up a heavy configuration tool or squinting at raw XML.

  • Embedded & AUTOSAR software developers
  • Model-based systems & software architects
  • Integrators reviewing a supplier’s ARXML
  • Anyone who just received an .arxml and needs to understand it
“Making ARXML files accessible and understandable — so you can spend less time reading XML and more time on the architecture.”

ARXML viewer — frequently asked questions

What is an ARXML file?
An ARXML file is the XML format defined by AUTOSAR to describe automotive software architecture — software components, their ports, interfaces and the connections between them. Because the raw XML is verbose and hard to read by hand, EasyARXML turns it into a clear, interactive diagram.
Are my ARXML files uploaded to a server?
No. EasyARXML parses your file entirely inside your web browser using JavaScript. The file never leaves your computer, is never uploaded, and is never stored anywhere. You can confirm this yourself by opening your browser’s Network tab while you load a file — there is no upload request.
Is EasyARXML free to use?
Yes. The online ARXML viewer is completely free — no sign-up, no account and no installation required. Just open the app and drop in a .arxml file.
Which AUTOSAR versions are supported?
EasyARXML reads Classic AUTOSAR 4.x ARXML files (the r4.0 schema), visualizing application and service software components, their P-Ports and R-Ports, compositions, and assembly and delegation connectors.
Do I need to install anything?
No installation and no plugins. EasyARXML runs in any modern web browser on Windows, macOS or Linux. It even works offline once the page has loaded, because all processing happens locally.
Can I export the diagram?
Yes. Once your ARXML is visualized you can auto-arrange the graph and download the diagram as a PDF report to share or archive.
