Vesta
Open any .html, .jsx, .tsx, .svg or .md file and watch it come alive — right on your Mac, in one click.
macOS 15 Sequoia required
Live Preview
Launch your files in a secure sandbox and flip between Desktop, Tablet and Phone to test how they really feel.
Watched Folders
Point Vesta at the folder where you save your work and it keeps a live, organised library — automatically, as new files appear.
Auto-discovers your prototypes as you add files to the folder.
Organises them in a sidebar — Library, Recents, Favorites.
Persistent across relaunches — your folder is always remembered.
Reload with ⌘R while you edit files externally.
