Where to start
The pages that cover the Laevitas core for BTC and ETH: the options walls, gamma and DVOL page, the options flow tape, and every underlying series in the CC0 dataset hub. Builders and agents pull the same numbers from the free JSON API and MCP server.
What Laevitas does better
Honesty first: Laevitas is the deeper options product by a wide margin. It covers many more assets and venues, models the whole volatility surface with skew and term structure, tracks dated futures basis, and lets a desk build custom dashboards. Our options coverage is BTC and ETH, daily snapshots rather than intraday, and we do not attempt surface analytics. Where we differ is the deal: the series we do record are free, downloadable in full, and served to agents without a key.
FAQ
Is there a free alternative to Laevitas?
For the core options picture on BTC and ETH, yes: ByKaranteli publishes daily open-interest walls by strike, dealer gamma exposure, the zero-gamma level, DVOL history and the largest option prints of the last 48 hours, free and without an account. For volatility surfaces, skew, dated futures and 1000+ assets, Laevitas is the right tool.
How do the prices compare?
Laevitas lists a free tier with one week of history, Premium at $50 per month per seat with one year of history and CSV export, and Enterprise at $500 per month per seat with historical API access (laevitas.ch/pricing, read 2026-09-02). ByKaranteli's options pages, datasets and API are free; a membership is for alerts and the live terminal, not for data.
Can I download the history?
Yes. The options open-interest snapshot, DVOL and options-flow series are CC0 datasets in CSV and JSON on the data hub, mirrored weekly to Kaggle and Hugging Face, and reachable through the public API and the MCP server.
Where does the data come from?
The Deribit and OKX options tapes are recorded by our own collection network and rolled up daily; nothing is scraped from another analytics site. Coverage notes and depth per series are listed on the methodology page.
