Comparison
Nansen built the gold standard for wallet labelling and on-chain flow analysis. OmniRisk is built for composite risk scoring, regime context, and multi-chain coverage at a fraction of the price.
Quick verdict
Nansen is the right choice if you need deep historical wallet intelligence and a large labelled-address database. OmniRisk is the right choice if you want a single interpretable risk score per token, real-time regime context, and cross-chain coverage without a $150/month minimum spend.

Lit dot = stronger on that dimension.
OmniScore aggregates seven signal layers into one number with full explainability. Nansen surfaces data — OmniRisk surfaces a verdict.
OmniRisk layers regime context — risk-on, risk-off, transitional — across every score and alert. Nansen has no equivalent.
Nansen starts at $150/month. OmniRisk has a free tier and a Pro plan at $29/month, making institutional-grade signal accessible to individual analysts.
Every token gets a natural-language risk summary from OmniRisk. Instead of interpreting charts, you get a plain-English explanation of what is driving the score.
Nansen's labelled-address database is unmatched. If you need to identify whether a wallet is a known VC, exchange, or smart money whale by name, Nansen wins.
Nansen offers years of historical on-chain flow data with rich filtering. OmniRisk is oriented toward real-time risk monitoring, not historical research.
Nansen specialises in wallet labelling and historical on-chain flow analysis, with an industry-leading database of tagged addresses. OmniRisk focuses on composite risk scoring — aggregating seven signal layers into one interpretable number per token, updated every 60 seconds. Nansen helps you identify who is behind a wallet; OmniRisk tells you how risky a token is right now.
Yes. Nansen starts at $150/month with no free tier. OmniRisk has a free tier with no credit card required and a Pro plan at $29/month. For teams that need composite risk scoring and regime detection — rather than deep wallet labelling research — OmniRisk is significantly more cost-effective.
No. OmniRisk does not maintain a labelled-address database comparable to Nansen's. If your primary use case is identifying named wallets — VCs, exchanges, known smart-money traders — Nansen is the right tool. OmniRisk's whale tracking focuses on behavioural patterns and risk signals from large holders, not identity attribution.
OmniRisk is built specifically for risk monitoring. It produces a composite risk score per token, monitors regime shifts, and sends threshold-based alerts when risk deteriorates. Nansen is a research and analytics platform — powerful for investigation but not designed around a risk score workflow. For ongoing portfolio risk monitoring, OmniRisk is the more purpose-built tool.
