The CoinMarketCap Fear and Greed alternative that scores every coin

Nebula is a CoinMarketCap Fear and Greed alternative that replaces one market-wide number with a Fear & Greed Index for every coin. Where CoinMarketCap gives the whole market a single daily 0-100 score, Nebula reads the actual crypto conversation with large language models and computes a per-token Fear & Greed reading across 100,000+ tokens. Free live tools, a full app, and a developer API.

Per-token Fear & Greed · LLM sentiment · 100,000+ coins

Why switch

CoinMarketCap tells you how the market feels in one number. Nebula tells you how each coin feels — built on social sentiment, updated intraday, and readable without an account.

Context

What the CoinMarketCap Fear & Greed Index does well

CoinMarketCap's index is a genuinely useful, trusted gauge. A good alternative is honest about where it wins.

Brand trust

CoinMarketCap is one of the most recognised names in crypto data. Its Fear & Greed Index carries that credibility by default — for a quick, defensible read on overall market mood, that trust matters.

Free and simple

The index is completely free and reduces market sentiment to a single 0-100 number, updated daily. There is nothing to learn: one dial, one glance, done. That simplicity is a feature, not a flaw.

Native CMC integration

The gauge lives right inside the CoinMarketCap charts and coin pages millions of traders already use every day. If your workflow is already on coinmarketcap.com, the index is one click away.

The difference

Where Nebula goes deeper

One market number is a starting point. Nebula is built for traders and researchers who need to know how the market feels about a specific coin, not just crypto as a whole.

Fear & Greed for every coin

The biggest gap in a single market-wide gauge is that BTC can be greedy while your altcoin is in freefall. Nebula's Crypto Fear & Greed Index computes a 0-100 score for 100,000+ tokens, so you can read sentiment for the exact coin you hold.

Social methodology, not just price

CMC's index leans on market data like volatility and volume. Nebula reads the conversation itself with LLMs, scoring how bullish or bearish each post is. Explore it on Market Sentiment and Token Sentiment.

Bullish vs bearish, in detail

A single index hides the split between conviction and panic. Nebula breaks sentiment into a 15-emotion model and shows the live bullish vs bearish balance, plus which tokens own the conversation.

Smart money, KOLs and an open API

Nebula surfaces the top callers and influencers whose posts move attention first — a social signal, not on-chain wallets — and exposes the same data through the Nebula API for trading systems and agents.

Choose the CoinMarketCap Fear & Greed Index if…

You want a fast, free, trusted gut check on overall crypto sentiment, and you are already living inside the CoinMarketCap ecosystem. One number, one glance, no learning curve.

Choose Nebula if…

You trade specific altcoins and need per-coin Fear & Greed, LLM social sentiment, intraday updates, mindshare, smart-money signals, and a clean API. Compare tools in the best crypto sentiment analysis tools guide, read up on mindshare vs sentiment, or check pricing.

Frequently asked questions

What is the best CoinMarketCap Fear and Greed alternative?

Nebula is the closest CoinMarketCap Fear and Greed alternative for traders who need more than one market-wide number. CoinMarketCap gives you a single 0-100 gauge for all of crypto, updated daily. Nebula keeps that headline read but adds a per-token Fear & Greed Index across 100,000+ coins, all built on large language models that score the actual social conversation on X, Reddit, YouTube and news. If you trade specific altcoins, per-token granularity is the difference.

Is there a free CoinMarketCap Fear and Greed alternative?

Yes. Both are free. CoinMarketCap hosts its Fear & Greed Index on coinmarketcap.com at no cost, and Nebula publishes its Fear & Greed Index, Market Sentiment, Mindshare and Bullish/Bearish tools as free public pages you can open without an account. Paid Nebula plans add deeper history and API access — see the pricing page for details.

How is Nebula different from the CoinMarketCap Fear and Greed Index?

The CoinMarketCap Fear & Greed Index is one number for the entire market, calculated daily from inputs like volatility, momentum, volume and market surveys. Nebula is built the other way round: it reads the crypto conversation itself with LLMs, scores how bullish or bearish each post is across a 15-emotion model, and rolls that up into a Fear & Greed score for every individual token — not just the market as a whole. One tells you the mood of crypto overall; the other tells you the mood of the specific coin you care about.

Does Nebula give a Fear and Greed score for individual coins?

Yes — that is the core reason to use it alongside or instead of CoinMarketCap. CMC's index is market-wide only. Nebula computes a dedicated 0-100 Fear & Greed reading for 100,000+ tokens, so you can check whether a single altcoin is in fear or greed even when the overall market gauge is flat. You can see it on the free Token Sentiment and Fear & Greed pages.

When should I just use the CoinMarketCap Fear and Greed Index instead?

If all you need is a quick, trusted, market-wide gut check on overall crypto sentiment, the CoinMarketCap Fear & Greed Index is genuinely the simpler choice. It is free, it is a household name, and it lives right inside the CoinMarketCap charts and coin pages you may already be using. Reach for Nebula when you need per-coin granularity, social-sentiment methodology, intraday updates, or data you can pull into a trading system via API.
