The CFGI alternative with social-first per-coin Fear & Greed

Nebula is a CFGI alternative that gives you a per-coin Fear & Greed Index the way CFGI does — a 0-100 score for individual tokens — but derives it from a social-first, LLM reading of the crypto conversation across X, Reddit, YouTube and news, and extends that coverage to 100,000+ tokens. Each score sits inside a full mindshare and narrative suite, with free public tools and a developer API.

Why switch

CFGI builds Fear & Greed from a market-data composite. Nebula reads what the crowd is actually saying — with large language models, across 100,000+ tokens — and shows you the mindshare and narratives moving each coin.

Feature-by-feature comparison

An honest side-by-side. CFGI leads on sub-daily timeframes; both platforms cover equities, while Nebula leads on social-first methodology, token breadth, and the mindshare and narrative context around each Fear & Greed score.

Context

What CFGI does well

CFGI is the closest competitor on per-coin granularity, and its intraday timeframes are a genuine advantage. A good alternative is honest about that.

Sub-daily timeframe granularity

CFGI publishes Fear & Greed on 15-minute, 1-hour and 4-hour intervals alongside the daily reading. If you scalp or trade short-term reversals and need intraday sentiment that refreshes within the hour, that depth is CFGI's real strength — Nebula's social index is built for the daily horizon, not the 15-minute one.

Established composite methodology

CFGI applies a market-data composite across crypto, equities, and indices. Nebula also covers equities and digital assets, but derives its signal from the language, attention, and actors inside market conversations. Which is more useful depends on whether you prefer a technical composite or a social-intelligence methodology.

Curated major-asset focus

For the roughly 100 large-cap assets CFGI tracks, its multi-timeframe composite is a clean, focused reference. If your universe is only the majors and you want intraday precision on them, CFGI's narrower, deeper approach is a reasonable fit.

The difference

Where Nebula goes deeper

Nebula approaches per-coin Fear & Greed from the opposite direction: it reads the conversation with large language models, then wraps each score in the wider attention picture around a token.

Fear & Greed for 100,000+ tokens

Where CFGI curates around 100 assets, Nebula computes a Fear & Greed Index across 100,000+ tokens — including long-tail and freshly launched coins that never reach a curated major-asset list. Drill into any one on the token sentiment page.

A social-first, LLM methodology

Instead of a market-data composite, Nebula reads every relevant post with large language models and scores it across a 15-emotion model — so the index reflects how bullish or bearish the crowd truly is. See the live read on Market Sentiment and bullish vs bearish.

Mindshare & narrative context

A Fear & Greed number is more useful with context. The Mindshare Leaderboard shows which tokens own the conversation, and narrative clusters reveal which themes are heating up around a coin — context CFGI's standalone index does not provide.

Smart-money signals & an open API

Nebula surfaces the top callers and influencers whose posts move attention first (a social signal, not on-chain wallet flow). The same intelligence — including per-token Fear & Greed — is available through the Nebula API for trading systems and agents.

Choose CFGI if…

You trade on intraday timeframes and need Fear & Greed on 15-minute, 1-hour or 4-hour intervals, prefer a market-data composite, and a curated set of major assets is enough coverage for your workflow.

Choose Nebula if…

You want a social-first Fear & Greed read across 100,000+ tokens, emotion-level sentiment, mindshare and narrative context, smart-money caller signals, free public indexes and a clean API — for trading, research, or building agents.

Frequently asked questions

What is the best CFGI alternative?

Nebula is the closest CFGI alternative if what you value is per-coin Fear & Greed. It scores a 0-100 index for individual tokens like CFGI does, but derives that score from a social-first LLM reading of crypto posts across X, Reddit, YouTube and news, and extends coverage to 100,000+ tokens instead of ~100 major assets. It also wraps each score in mindshare and narrative context CFGI does not offer. If your priority is intraday timeframes, CFGI is still the better fit.

Is there a free CFGI alternative for per-coin Fear & Greed?

Yes. Nebula publishes a live Crypto Fear & Greed Index and per-token sentiment as free public pages you can use without an account. Paid plans unlock the full app, deeper history and API access — see nebula.hiddensystems.ai/pricing for current tiers. Nebula never quotes a price on this page because plans change; check the pricing page for the live numbers.

How is Nebula different from CFGI?

CFGI builds its per-coin Fear & Greed from a market-data composite and adds sub-daily timeframes. Nebula is social-first: it reads financial-market conversations with large language models, scores them across a 15-emotion model, and computes Fear & Greed for over 100,000 tokens. Nebula then places each coin inside a broader suite — a mindshare leaderboard, narrative clusters, smart-money caller signals and an influencer leaderboard — so you see not just the number but why sentiment is shifting. Both platforms also cover equities.

When should I pick CFGI over Nebula?

Pick CFGI if you trade on intraday timeframes and need Fear & Greed refreshed on 15-minute, 1-hour or 4-hour intervals, or prefer its market-data composite methodology. Nebula is built around social signals rather than sub-daily market composites. For long-tail token coverage, equities sentiment, and social context, choose Nebula.

Does Nebula cover more coins than CFGI?

Yes, substantially. CFGI focuses on around 100 established crypto assets. Nebula computes sentiment and a Fear & Greed reading across 100,000+ tokens, including small-cap and newly launched coins that never appear on a curated major-asset list. That breadth is useful if you research early-stage or long-tail tokens where a social-first signal is often the only sentiment data available.
