Open MLAPP files in your browser
The app MATLAB's App Designer saves: its window and its code in one file. Open one right here and read it all, no MATLAB needed. Nothing leaves your device.
Or drop it anywhere on this page
What you'll see
Your app opens with the picture App Designer saved of its window, its components and its whole code, with nothing in it running.
- Its window as it was last saved
- Every component by kind • Its callbacks
- The whole class in MATLAB's colors
- Export • Save as an .m file, as HTML or as PDF
About MLAPP
App Designer came with MATLAB R2016a to build apps with windows, buttons, sliders and plots, and an .mlapp is what it saves. Engineers and students share their tools and coursework this way, and MATLAB Compiler turns one into an app of its own.
An MLAPP is a ZIP in Office's Open Packaging, like a live script: the app's code, a class App Designer writes, as an XML document, its layout in a MAT-file, and a picture of its window from when it was last saved.
Filepeek reads the package in your browser, with nothing in it running: the picture of its window, the components the app declares by kind, its callbacks, and the whole class in MATLAB's colors. Export saves the code as an .m file, as App Designer's Export to .m File does, or the page as HTML or PDF.

Questions
How do I open an .mlapp file without MATLAB?
Drop it on this page or choose Peek an MLAPP. The picture of its window shows first, then its components, callbacks and code.
Can I run the app?
No. Filepeek only reads it, and nothing in it runs. Running it takes MATLAB, or MATLAB Runtime once MATLAB Compiler has made it an app of its own.
How do I get the code out of an .mlapp?
Choose Export, then Save as MATLAB script, and the whole class saves as an .m file, as App Designer's Export to .m File does.
