The Cookie.fun alternative for mindshare across all of crypto

Nebula is a Cookie.fun alternative that measures mindshare across the whole crypto market — not just AI-agent tokens — and pairs it with LLM-scored sentiment and a Fear & Greed Index for 100,000+ individual tokens. Where Cookie.fun goes deep on one category, Nebula reads every relevant post across X, Reddit, YouTube and news to tell you what owns attention and how the market feels about it. Free live tools, a full app, and a developer API.

Why switch

Context

What Cookie.fun does well

Cookie.fun owns the AI-agent attention niche, and for that job it is genuinely the best in class. A good alternative is honest about that.

AI-agent indexes & Cookie Score

Cookie.fun’s Cookie Score and agent indexes are purpose-built to rank AI-agent projects by mindshare. If your entire focus is the agent meta, that specialised depth is hard to beat.

Agent leaderboards

Its agent leaderboards surface which individual AI agents and frameworks are gaining attention right now — a level of category-specific granularity aimed squarely at agent-token traders.

DataSwarm data layer

Cookie DAO's DataSwarm tracks AI-agent project mindshare as a structured data layer that other apps and agents can build on — a strong foundation if you are building tooling inside the agent ecosystem.

The difference

Where Nebula goes deeper

Nebula is built for traders and researchers who need mindshare and sentiment for the whole market — every token, not just the agent narrative.

Mindshare beyond AI agents

Where Cookie.fun concentrates on agent projects, Nebula's Mindshare Leaderboard ranks share of conversation across every crypto category, so a heating agent meta is visible next to L1s, DeFi, memes and majors.

Sentiment, not just a score

Nebula reads every relevant post with large language models and scores it across a 15-emotion model, so you see how bullish or bearish attention is — not just how loud. Explore it on Market Sentiment and Bullish vs Bearish.

Fear & Greed for any token

Nebula computes a Fear & Greed Index for 100,000+ tokens and per-coin token sentiment, so you can read the mood of a specific coin — something an agent-focused index doesn't cover.

Smart money, free tools & an API

Nebula layers on the callers and influencers moving attention first, alongside the Altcoin Season Index. Live indexes are free public pages, and the same data is available through the Nebula API for trading systems and agents.

Choose Cookie.fun if…

Your focus is the AI-agent ecosystem specifically and you want purpose-built agent indexes, the Cookie Score, agent leaderboards, and the DataSwarm data layer for individual agent projects.

Choose Nebula if…

You want mindshare and sentiment across all of crypto, per-token Fear & Greed, emotion-level social signals, smart-money and caller tracking, free public indexes, and a clean API — for trading, research, or building agents.

Frequently asked questions

What is the best Cookie.fun alternative?

Nebula is the strongest Cookie.fun alternative if you want mindshare across all of crypto rather than only AI-agent tokens. It covers the same core job — measuring which projects own the conversation — and adds LLM-scored sentiment and emotion, a per-token Fear & Greed Index, narrative tracking, and smart-money signals. Cookie.fun remains excellent inside the AI-agent niche, but Nebula spans every category.

Is there a free Cookie.fun alternative?

Yes. Nebula publishes several live indexes as free public pages you can use without an account, including the Crypto Fear & Greed Index, the Mindshare Leaderboard, and Market Sentiment. Paid plans unlock the full app, deeper history, and API access — see pricing at nebula.hiddensystems.ai/pricing.

How is Nebula different from Cookie.fun?

Cookie.fun (Cookie DAO) grew up around AI-agent tokens — its Cookie Score, agent indexes, and DataSwarm data layer are built to measure agent-project mindshare in depth. Nebula is a broader intelligence layer: it reads every relevant crypto post across X, Reddit, YouTube and news with large language models to score sentiment and emotion, computes Fear & Greed for individual tokens, and tracks smart-money callers — across the whole market, not one meta.

Does Nebula track AI-agent tokens like Cookie.fun?

Nebula tracks AI-agent tokens as part of its market-wide mindshare and sentiment coverage, so you can see how the agent narrative stacks up against everything else in crypto. It does not, however, offer the dedicated agent indexes, Cookie Score, or agent-specific onboarding that Cookie.fun specialises in — for the deepest single-category agent analytics, Cookie.fun still leads.

When should I pick Cookie.fun over Nebula?

Choose Cookie.fun when your focus is squarely the AI-agent ecosystem and you want its purpose-built agent leaderboards, Cookie Score, and DataSwarm data on individual agent projects. If you need mindshare and sentiment across all of crypto, per-token Fear & Greed, and smart-money signals in one place, Nebula is the better fit.
