Worth it? Your Git knows!

Source Trace adds AI Blame to your Git and tracks new code model-by-model. One-shot or painful rewrite? Find your best model.

Rankings based on real usage data from developers tracking AI code with Source Trace.

One-Shot

Not all models are good at coding. See daily stats: from one-shots to painful rewrites. Which model used to be the best, but not anymore?

Example: Git may show 2.9K AI lines committed. Source Trace also shows 1.3K written then dropped before commit, plus 1.2K older AI lines rewritten. See beyond tokens.

AI Git Blame

See exactly which code was generated, even when multiple models were used in one commit. Track agent and model versions.

AI Blame uses Git for storage. Your code stays on your machine.

Commit Diff View Commit Diff View

Compare Models

Some models generate a lot of code, but not much gets shipped. See which AI code survives reviews and rewrites. Find your best model.

What works well for UI development, might not be the best for backend.

Why Source Trace?

AI Git Blame

Track who wrote each line - AI or your teammate? Which version of each model was used, even months later.

Model Comparison

Compare different AI models and coding assistants. See which ones are good at one-shot in your codebase.

Community Insights

See AI Model rankings to find best new models. We are not ranking token use or synthetic benchmarks - only real coding by real developers and their agents.

Privacy First

Your code never leaves your machine. We do not sell your data. We are not affiliated with AI model or cloud providers.
