Ketchup vs GitClear: Math vs History

GitClear has emerged as a developer-friendly alternative to "surveillance" platforms like LinearB and Jellyfish. Their core innovation, Diff Delta™, measures "durable code changes" instead of raw lines of code.

This is a good thing. But it's not the whole picture.

The Diff Delta Innovation

GitClear is right that "Lines of Code" is a terrible metric. A developer who deletes 500 lines of dead code is doing more valuable work than one who adds 500 lines of boilerplate.

Diff Delta solves this by tracking "durable" changes—code that sticks around. It filters out churn (code added and immediately deleted) and highlights meaningful refactors.

GitClear: "Your Diff Delta this week was 1,200. You're in the 80th percentile."

This is useful for process debugging:

• Is the team churning too much?
• Is one developer doing all the heavy lifting?
• Are we shipping or just rewriting?

The "So What?" Problem

But here's the gap: Math doesn't tell a story.

Knowing your Diff Delta is 1,200 doesn't help you:

• Explain to your CEO why the launch was delayed.
• Write the changelog for your users.
• Create a LinkedIn post celebrating your team's work.
• Onboard a new hire on "what happened last quarter."

Diff Delta tells you that a big change happened. It cannot tell you why.

Where Ketchup Comes In

Ketchup is the Narrative Layer on top of your codebase. We don't just count changes—we read them.

When our Deep Dive engine sees 15 commits touching the auth/ directory, we don't just report "Auth: 1,500 Diff Delta." We report:

"Refactored the authentication system to support SSO with Google and GitHub. The team reduced session-related bug reports by 40%."

This is Contextual Intelligence, not just statistics.

The Best of Both Worlds

With Ketchup, you don't have to choose between metrics and narrative. Our Momentum Engine now tracks Line Durability natively—identifying code that sticks around versus code that churns.

But unlike a dashboard that just shows "87% Durability," Ketchup weaves that data into the story:

"Alice shipped 1,200 lines of code this week with a 92% durability score. She's not just shipping fast; she's building the foundation."

Conclusion

GitClear proved that "Durable Code" is the right metric. Ketchup proves that Narrative is the right way to deliver it.

Don't just measure your team's impact. Broadcast it.
