Why this tool is flagged
LangChain dropped 43 points this week alone — a sharp, fast decline. Combined with its 30-day trajectory (-15 pts), this suggests a recent momentum reversal rather than a slow fade. Sharp drops in the AI Frameworks space often precede a category shift toward a newer tool.Pricing
