a better everyday tool.

The work goes
with you.
At your desk or away from a connection, your workspace is right there. Templates, documents, and files stay on your device.
NO ACCOUNT. NO CLOUD DEPENDENCY.
The web app works offline after its first download. Export a workspace backup to keep a separate copy.
A preview as you build
Edit the template source and see your paginated document update alongside it.
Forms that do the math
Computed table totals, conditional fields, and validation use the shared Rebar engine.
More than words on a page
Bring in photos, add signatures, and use template images such as your company logo.
A record of what changed
Versioned templates keep existing documents tied to the version they were created with.

Is Studio really free?
Yes. Rebar Studio is free and open source under the GPL-3.0-or-later license. You can use it without an account or a Rebar subscription.
What is the difference between web and desktop?
Both let you create templates and fill documents locally. The desktop app exports PDFs directly through Chromium. The web app uses your browser’s print dialog and can be installed for offline use after the initial download.
Where are my documents stored?
On your device. The web app uses browser storage; the desktop app has its own local workspace. Export a workspace backup from Settings regularly, especially before clearing browser data or moving to another device.
Do I need to know how to code?
You can fill documents without writing code. Creating or changing a template means editing .reb source, which combines an HTML layout with form fields. The starter gallery, snippets, and live preview help you get going.
How does it work with Rebar?
Studio and Rebar use the same .reb engine. Export a .reb template, or a .rebpack with its images, and import it into Rebar. Sharing is through files; Studio does not automatically sync your workspace to the platform.
