A gallery for HTML prototypes
Showroom is a gallery for HTML prototypes. Upload .html files, organize them by project, preview them side-by-side, and share a link with your team. That's it.
Everything you need to share prototypes
Upload, organize, preview, and share HTML files with your team. No installs, no config files, no Slack threads full of zip attachments.
Gallery Organization
Group prototypes into named galleries. Each gallery gets its own shareable URL, so you can keep client work separate from internal experiments.
Live HTML Preview
Click any file and see it rendered instantly in an iframe. No downloads, no local setup, no "open in new tab" workaround.
Team Collaboration
Invite teammates by email. Everyone on the gallery can upload, preview, and leave comments. No account required to view shared links.
Resizable Split Pane
Drag the divider to resize the file list and preview panel. Give the preview 80% of the screen or keep it 50/50 while browsing.
Shareable Links
Every gallery and every file gets a unique URL. Send a link to a specific prototype and the recipient lands right on it.
Thumbnail Grid
See every prototype as a live thumbnail. Adjust the grid size with a slider so you can scan 6 files or 30 at a glance.
Three steps. No learning curve.
Create a gallery
Name it after your project, client, or sprint. Galleries keep your prototypes grouped and easy to find.
Upload HTML files
Drag and drop .html files into the gallery. Showroom stores them and generates live thumbnails automatically.
Share with your team
Invite collaborators by email or copy a direct link. They can browse, preview, and navigate with arrow keys.

Is my HTML stored on your servers?
Yes. Uploaded .html files are stored securely so your team can access them from any device. Files are private to your gallery unless you share a link.
Can I share galleries with non-users?
Yes. Anyone with the gallery link can view and preview files. They do not need a Showroom account. Only editing and uploading require sign-in.
What file types does Showroom support?
Showroom accepts .html files. The previewer renders them in a sandboxed iframe, so CSS and inline JavaScript work as expected.
How does team collaboration work?
Gallery owners can invite teammates by email. Invited members can upload, delete, and rearrange files within that gallery.
How much does Pro cost?
Pro is $3/month. It gives you up to 20 galleries with 50 files each (5 MB), 10 members per gallery, no expiry, and no ads. You can also get the Crate Pass for $15/month to access every Cashew Crate app.
Can I use keyboard shortcuts to browse?
Yes. Arrow keys move between files in the preview pane, so you can step through prototypes without reaching for the mouse.
