CastLens transforms the Farcaster social graph into a navigable constellation of influence, relationships, and emerging trends. Unlike conventional social analytics tools that merely count metrics, CastLens interprets the semantic fabric of decentralized social interactions, revealing hidden patterns and predictive signals within Farcaster's vibrant ecosystem. Think of it as a telescope for the social universe—where others see stars, we map galaxies.
Built on Base with a Mini App interface, CastLens serves researchers, community builders, and strategic participants who seek to understand not just what is happening, but why it matters and where it's heading.

# Using npm
npm install -g castlens-engine
# Using Bun
bun add castlens-enginecastlens --network mainnet \
--profile ./config/social-scope.json \
--metrics influence,cohesion,velocity \
--output format=json \
--streamThis command initiates a real-time analysis session, streaming processed intelligence about network dynamics directly to your console or designated endpoint.

Moves beyond follower counts to visualize influence vectors, community overlap, and idea transmission pathways. See how narratives propagate through specific network substructures.
Leverages both OpenAI and Anthropic's Claude APIs for complementary analysis—GPT-4o for broad pattern recognition and Claude for nuanced, context-aware interpretation of social dynamics.
Identifies emerging topics and potential trend crystallization before they reach mainstream awareness within the network, using proprietary velocity and cohesion algorithms.
Processes casts in 15+ languages, detecting cultural nuances and cross-community idea translation, not just simple keyword translation.
Adaptive visualization interface that reorganizes based on analytical focus—from micro-conversation detail to macro-network trend displays.
Continuous network observation with configurable alerting for specified triggers: unusual activity spikes, emerging community formation, or sentiment shifts.
Every dashboard feature is accessible via REST and GraphQL endpoints, enabling integration with custom tools, automated agents, and external data systems.
CastLens employs a sophisticated dual-LLM architecture:
OpenAI GPT-4o Integration:
- High-speed pattern recognition across large datasets
- Multi-modal understanding when processing cast media
- Scalable summarization of community discussions
Anthropic Claude 3.5 Sonnet Integration:
- Nuanced interpretation of social context and subtleties
- Ethical alignment verification of analytical conclusions
- Long-form narrative construction from fragmented signals
These systems work in concert through our Orchestration Layer, which assigns analytical tasks based on complexity, required nuance, and processing constraints, ensuring optimal insight generation.

#castlens - Direct Support: 24/7 automated triage with escalation to human specialists
CastLens represents a paradigm shift—from social media as content distribution to social networks as collective intelligence organisms. By making the implicit structures of decentralized communities explicit and navigable, we enable more informed participation, more meaningful connection, and more authentic collaboration across the evolving landscape of Web3 social interaction.
