# Deep comparison

The short version is on [Overview → How Stratix compares](/1.-introduction/how-stratix-compares.md). This page is the long version: feature-by-feature tables and the qualitative trade-offs.

## What's distinctly Stratix

These are capabilities Stratix offers today that the alternatives don't match:

1. **Public model leaderboard.** 175+ models scored against 52+ benchmarks at `stratix.layerlens.ai`. Anonymous browsing, refreshed quarterly. No competitor operates a public catalog of this scale.
2. **Public benchmark catalog.** Open browsing of 52+ benchmarks with descriptions and per-model scores.
3. **Quarterly research reports.** Long-form, dated, methodologically transparent reports on the model frontier.
4. **Industry pages.** 13 industries with scenario mappings to platform capabilities.
5. **Migration guides** from LangSmith, Braintrust, Galileo, Promptfoo, MLflow, Arize.
6. **Pricing transparency.** Free tier, ECU PAYG visible without a sales call.
