The LunarCrush alternative built on emotion, not just volume

Nebula is a LunarCrush alternative that swaps social-volume scores for meaning: instead of ranking coins by how loud they are, it reads every relevant crypto post with large language models to score sentiment and emotion, tracks which narratives are heating up, and computes a Fear & Greed Index for 100,000+ individual tokens. Where LunarCrush leans on Galaxy Score and AltRank, Nebula tells you how bullish or bearish the conversation actually is.

What LunarCrush does well

LunarCrush built the social-volume category and is the right tool for some jobs. A good alternative is honest about that.

Social volume & Galaxy Score

LunarCrush is the category leader for raw social-volume tracking. Its signature Galaxy Score and AltRank composites aggregate posts, engagement and interactions into a single momentum read — a fast, well-understood way to see which coins are trending loudest.

TikTok and platform breadth

LunarCrush indexes TikTok alongside X, Reddit, and YouTube. Both products cover equities and digital assets, but LunarCrush's additional social platform and long-established raw volume feeds remain genuine strengths.

Mature, widely-integrated API

LunarCrush has a long-established API and data products that many existing tools, terminals and dashboards already plug into. If you need a battle-tested social-data feed with an existing integration ecosystem, that maturity counts.

Where Nebula goes deeper

Nebula is built for traders and researchers who need to know how the market feels and why, token by token — not just how loud the chatter is.

Emotion, not volume

A high Galaxy Score tells you a coin is being talked about; it doesn't tell you whether that talk is fear or euphoria. Nebula reads each post with LLMs and scores it across a 15-emotion model, separating loud-but-neutral noise from real conviction. See it live on Market Sentiment and Token Sentiment.

Narratives, not just tickers

LunarCrush ranks individual assets; Nebula also groups attention into tracked narrative clusters, so you can see which themes are heating up before they show up as a spike on any one coin. Pair that with the Mindshare Leaderboard to see share of conversation by token and theme.

Fear & Greed for any token

Beyond a single market gauge, Nebula computes a Fear & Greed Index for 100,000+ tokens, and a simple bullish or bearish read per coin — sentiment for a specific asset, not just an aggregate score.

Smart-money callers & open API

Nebula surfaces the top callers and influencers whose posts move attention first — a social smart-money signal, not on-chain wallet flows. The same intelligence is available through the Nebula API for trading systems and agents.
