New coding model dropped. Worth it? Your Git knows.
Source Trace adds AI Git Blame to your repository and tracks coding stats per model. See how much code each model generates, how much is committed, and how much is rewritten. Find which model works best for your codebase.
Works with most AI tools automatically - no configuration and no agent hooks required. VS Code extensions and CLI agents supported.
Source Trace can also consume optional agent tool-hook hints from supported tools. These hooks are not required, but when a tool emits a successful exact-path edit event, Source Trace can use it to resolve timing races where provider logs are written after the file save. Pre-edit hooks are treated as intent only; only successful exact-path post-edit evidence can attribute or upgrade unknown lines.
Getting Started
Install the Source Trace extension
Start coding - Source Trace automatically tracks your manual and AI code
Find your One-Shot model: Not all models are good at coding. See daily stats: which model generates code in one shot, which one requires code rewrites. Which model used to be the best, but not anymore?
AI Blame: See exactly which model generated each line of code, even when multiple models were used in one commit. Track agent and model versions. AI Blame supports local storage, with optional Git storage in your remote repository. Your code stays on your machine.
Compare your 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.
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. Head to https://srctrace.com/rankings.
