Free finds the problem. Pro explains it.

Free gives you the complete diagnostic toolkit — runs on your machine, uses your own API key, costs nothing to start. Pro adds a hosted AI investigator that reads your execution traces and tells you exactly what broke, why, and where the impact spreads — no key to manage, no setup.

Both plans give you the full diagnostic toolkit. The difference is who reads the output.

Billing cadence

FreeLocal workflow
Free forever
The complete local diagnostic workflow inside VS Code — profiling, blast-radius tracing, payload generation, contract assertions, regression detection, test generation, and evidence-backed commit gating. Bring your own provider key (OpenAI, Anthropic, Gemini, or Bedrock). Last 10 runs per function, rolling.

Know which functions, routes, and downstream callers are affected before you push — blast-radius tracing and dependency mapping on every change, automatically.

Regression detection flags behavioral changes automatically. AI generates test payloads from real traces — no fixtures, no config.

Evidence-backed commit gating via git hook — risk analysis runs before every push, with your own provider key (OpenAI, Anthropic, Gemini, or Bedrock).

Pro Monthly
A hosted AI model that reads your execution traces and surfaces root cause automatically. The Diagnose run walks any endpoint from request to response — route handler, models, queries, timings, deviations. The full API workbench. Unlimited run history — track how your system changes across every deployment.

A hosted AI model that reads your execution traces and explains what it finds — root cause, blast radius, and the exact call path that broke. No API key to manage.

The Diagnose run: feed any endpoint a request and get a full execution walkthrough — route handler, models, queries, timings, and what deviated from baseline.

Unlimited run history synced across sessions — track how your system's behavior drifts across every deployment, not just the last ten runs.

Use the same account you use in your IDE so billing and product access stay aligned.

Feature Comparison

Free gives you the data. Pro reads it for you.

Every row maps to a capability in the extension. Free rows run on your machine with your own key. Pro rows are powered by a hosted AI model — no key to configure, no setup required.
