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

Use with Claude Code
Install the Workbooks skill so Claude Code knows how to scaffold, lint, and ship workbooks — file format, runtime API, build pipeline, and deploy guidance all on hand.

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/Workbooks.pkg
curl -fsSL https://workbooks.sh/dl/sha256.txt | shasum -a 256 -c --ignore-missingThe macOS installer is signed with Apple Developer ID and notarized by Apple — Gatekeeper accepts it without prompts. Microsoft Trusted Signing for Windows and GPG-signed Linux artifacts are wired in CI and ship when the corresponding signing keys land.
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.
