agentica and voltagent
These are competitors: both provide TypeScript frameworks for building AI agents with function calling capabilities, targeting the same use case of multi-agent orchestration, though VoltAgent emphasizes a broader "engineering platform" while Agentica focuses specifically on compiler-enhanced function calling.
About agentica
wrtnlabs/agentica
TypeScript AI AI Function Calling Framework enhanced by compiler skills.
Supports three integration protocols—TypeScript classes, Swagger/OpenAPI documents, and MCP servers—allowing developers to compose agents by simply declaring existing functions without manual schema writing. Uses compiler-driven schema generation and automatic JSON Schema conversion across LLM vendors (OpenAI, Gemini, Claude, DeepSeek, Llama), while a selector agent filters candidate functions to optimize token consumption and reduce hallucination errors during function calling.
