Feature-by-feature comparison
An honest side-by-side. Alternative.me wins as the free, established standard with a dead-simple public API; Nebula wins on per-token Fear & Greed and LLM social sentiment.
What the alternative.me Fear & Greed Index does well
Alternative.me built the original crypto Fear & Greed Index and is the right tool for some jobs. A good alternative is honest about that.
The original, standard single number
When people say “the crypto Fear & Greed Index,” they usually mean alternative.me's. It is the de-facto standard 0-100 gauge for overall market mood, and that recognition makes it easy to reference and easy for readers to trust at a glance.
A dead-simple free public API
Alternative.me exposes today's value through one free endpoint that thousands of widgets, dashboards and bots already embed. If all you need is the current market number dropped onto a page or into a script, nothing is simpler.
Free and frictionless
It is free, needs no account, and has been running long enough to build a historical chart people recognise. For a quick, zero-cost read on whether the broad market is fearful or greedy, it does exactly one job well.
Where Nebula goes deeper
Nebula is built for traders and researchers who need Fear & Greed for a specific coin — and the social context behind it — not one number that mostly tracks Bitcoin.
Fear & Greed for any token
Where alternative.me reports a single blended market gauge, Nebula runs the same 0-100 scale down to the coin. See it live on the Crypto Fear & Greed Index and drill into any token's reading on Token Sentiment.
Sentiment, not market mechanics
Alternative.me blends volatility, volume and dominance. Nebula reads every relevant post with large language models and scores it across a 15-emotion model — so the number reflects how the crowd feels, which you can explore on Market Sentiment and Bullish vs Bearish.
Attention and smart-money context
A single fear number tells you nothing about why. Nebula pairs its index with the Mindshare Leaderboard and the influencers and top callers moving a narrative first — social signals, not on-chain wallet flows.
Free tools and a full data API
Nebula's indexes are free public pages, and where alternative.me's API returns one value, the Nebula API exposes per-token sentiment, mindshare and narratives for trading systems and agents. See pricing for plan tiers.
Which should you choose?
You want the original, free, de-facto standard single number for overall market mood, and a dead-simple public API to embed a widget or feed a bot. For a quick, zero-cost read on whether the broad market is fearful or greedy, it is the established default.
You want Fear & Greed for a specific token, LLM social sentiment across a 15-emotion model, and the mindshare and smart-money context a single blended number can't give you. Compare the wider field in best crypto sentiment analysis tools and read mindshare vs sentiment to see how the signals fit together. New to the terms? The market intelligence glossary covers the basics.
