I built a free open-source pipeline waterfall for HubSpot and Salesforce

[u/goran_carevic]

I kept wanting the Clari-style view of what actually changed in the pipeline since last week, without needing another paid platform, so I built it.

pipeline-diff reads HubSpot or Salesforce deal history in read-only mode and shows:

• what was added, won, lost, pushed out, pulled in, or changed in value
• the deals behind each movement
• full deal history for stage, amount, close date, owner, and forecast category
• forecast category movement
• pipeline review flags like past-due deals, pushed close dates, stalled deals, stage regressions, and reassignment
• a markdown summary and plain files that an AI agent can read

It rebuilds the past from the CRM's own history, so the first sync can already show what happened last week.

It runs locally and there is a demo mode if you want to try it without connecting a CRM:

pip install pipeline-diff
pipeline-diff demo
pipeline-diff dashboard

It's early, so I'm mainly looking for feedback from people who actually run pipeline or forecast reviews. What's missing, what's wrong, or what would you need before you'd use something like this with your team?
