Open and save .workbook.html files like documents.
Workbooks are plain HTML files. The runtime is a 1 MB background daemon that lets your browser save edits back to disk. Install once; every workbook on your machine just works.
curl -fsSL https://workbooks.sh/install | sh
All downloads are SHA-256 verified and Apple-notarized for macOS. View checksums.
Verifying your download
Every binary is checksummed in
/dl/sha256.txt. The
install.sh script verifies the
SHA-256 of the downloaded binary against this manifest before it
runs anything — a corrupted or MITM'd download is refused.
Manual verification:
curl -fsSLO https://workbooks.sh/dl/workbooksd-aarch64-apple-darwin
curl -fsSL https://workbooks.sh/dl/sha256.txt | shasum -a 256 -cCode-signing pipeline (Apple Developer ID, Microsoft Trusted Signing, GPG-signed Linux artifacts) is wired in CI and activates as soon as the corresponding signing keys are added to repository secrets. Until then, integrity is enforced via SHA-256 only.
What it does
workbooksd runs in the background and listens on
127.0.0.1:47119. When you double-click a
.workbook.html file, the daemon binds it to a session
token, opens your default browser, and the page can save edits
straight back to disk. No app window, no Electron, no custom IDE.
What it doesn't do
- Phone home. Bound to localhost; no telemetry.
- Touch files you didn't open. Tokens scope writes to a single canonicalized path.
- Replace your editor. Workbooks are HTML — edit them in any tool you like.
