ContextWhat Santiment and LunarCrush each do well
Both are established tools with real, distinct strengths. A useful comparison is honest about where each one wins outright.
Santiment: on-chain & fundamentals
Santiment's advantage is its broad metric catalogue built on on-chain data — exchange flows, holder distribution, whale transactions and network activity — plus developer/GitHub activity that hints at whether a project is genuinely building. If your edge is fundamentals and chain behaviour, this is where Santiment is hard to beat, and it is data Nebula deliberately does not collect.
LunarCrush: social breadth & scores
LunarCrush is social-first and covers a huge universe fast. Galaxy Score and AltRank turn social volume, engagement and market data into ready-made rankings, and it spans crypto and stocks — handy if you track equities alongside tokens. For raw social coverage and one headline number, LunarCrush is the more social-native tool.
Both: mature APIs
Santiment and LunarCrush both expose deep historical data through developer APIs, so quant teams and agents can pull metrics programmatically. Nebula also ships an API, but the underlying data each returns is different — Santiment's chain metrics, LunarCrush's social aggregates, Nebula's LLM sentiment.
