Which should you choose?
Choose Stocktwits if you want a social network for investors, direct community participation, ticker streams, user follows, replies, and a transparent bullish or bearish vote from that community. It is the more natural product for joining the conversation and watching how retail traders react in public.
Choose Nebula if you want a Stocktwits alternative that treats sentiment as one signal inside a broader stock-research system. It is the better fit for comparing companies by mindshare, separating attention from tone, checking a stock-specific Fear and Greed reading, and moving the same structured intelligence into an API or agent workflow.
Neither product replaces filings, valuation, or risk management. The practical test is source fit: decide whose opinion you need to measure, evaluate the signal around a sample of known events, and check whether it improves discovery, verification, and documentation rather than only producing a persuasive number.
