Sourceline: see which team files use a component before you change it

Hi everyone. I built Sourceline because Figma shows a component's variants, but not which of your team's files use it. People have asked for this in Suggest a feature since 2021: https://forum.figma.com/suggest-a-feature-11/see-where-component-is-used-find-component-instances-across-files-17758 

Sourceline is a widget you place next to a main component in your library file. It shows:

  • How many team files and instances use the component
  • Which of those files are active, quiet, or inactive
  • A High, Medium, or Low impact badge, before you publish a change
  • Every file that uses it, latest edit first, with its Dev Mode status

You set it up once per library file. Results are saved in the file, so teammates see them without signing in. Later scans read only the files that changed.

Two limits to know: the first scan takes about 4 minutes for every 60 files, because of Figma's API rate limit, and instances nested inside other instances are counted where their main component lives.

It's free: https://www.figma.com/community/widget/1686375993972598287/sourceline 

If you run a design system, I'd like to know where the numbers surprised you, and what you'd want it to show next.

Version 2 is live. New in this version:

 

Usage per variant: click Show variants to see each variant's instances across the team, the files that use it, and its instances in this file. Unused variants are listed last, so you can see which ones are safe to change. This one came from a comment on the Community page.

 

Tokens board: on an empty board, click Show tokens to see the file's variables and styles as a graph, from raw values to each alias. Click a token to highlight its chain, and edit its value or alias from there.

 

Refresh: when the last scan is more than 7 days old, Refresh reads only the files that changed.

 

Lower-access warning: if you can't see every folder the last scan read, Sourceline asks before it scans.
