Fingerprint the row
Turn the selected values into a deterministic fingerprint.
Row-aware sign-off
See whether this exact row version is still signed off.
Signlight adds a compact traffic-light sign-off to Coda tables. Green means the selected fields still match. Yellow means the row changed. Red means there is no active sign-off.

Built from Coda blocks
Sign-off without a second system.
Add Signlight formulas and native Coda buttons to an existing table. You choose which fields define the version being signed.
Sign with Coda
Native buttons capture the current user and timestamp in the row.
Spot later edits
A changed fingerprint automatically turns green to yellow.
Data stays in your doc
No Reware backend.
The Pack has no authentication, storage, analytics or external network calls. Fingerprints, signer and time remain ordinary Coda row values under your workspace controls.
Small by design
Make row approval visible.
Signlight is a lightweight acknowledgement tool, not a legal e-signature or regulated approval system.
