Decision brief

Flappy is an agent-oriented SDK using Rust for robust LLM integration, with current support for Node.js, Kotlin/Java, and C#, targeting developers needing versatility in language choice.

Good fit when

  • If your team uses Rust or plans to integrate with Node.js, Kotlin, Java, or C#.
  • When you need a production-ready solution for LLM capabilities without waiting for additional language support.

Avoid when

  • Avoid if your primary development languages are Ruby, PHP, Go, or Python and you require immediate use of these languages.
  • Not ideal if your project requires an SDK in early stages of development or is not production-ready as Flappy emphasizes stability and readiness.
