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.

macOS .pkg is signed with Apple Developer ID + notarized by Apple. All downloads are SHA-256 verified — 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/Workbooks.pkg
curl -fsSL https://workbooks.sh/dl/sha256.txt | shasum -a 256 -c --ignore-missing

The 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.
