Koine

Summary

Koine HTTP gateway + SDKs that expose Claude Code CLI as a REST API. Koine (koy-NAY) — the common Greek that connected the ancient Mediterranean. Koine connects your apps to Claude Code. Why Koine? Claude Code is Anthropic's agentic coding assistant. It reads files, runs commands, edits code, and uses tools autonomously. But it's a CLI, not an API. Koine makes Claude Code callable from your applications. Deploy it as a Docker service, call it from any language, get structured typed responses. Why Claude Code Instead of a Standard LLM SDK? With a typical LLM SDK, you get text in → text out. Tool use, file access, and code execution require building your own orchestration layer. Claude Code is that orchestration layer: Agentic loop built-in : tool calls handled automatically, no orchestration code : tool calls handled automatically, no orchestration code File system and bash access : read, write, edit files and run commands : read, write, edit files and run commands Skills and commands : extend with domain knowledge and custom workflows : extend with domain knowledge and custom workflows MCP support : connect to external tools via Model Context Protocol : connect to external tools via Model Context Protocol Battle-tested: Anthropic's own agentic runtime, refined in production Why Koine Instead of Claude Code Directly? Claude Code CLI Koine Interactive terminal REST API for any language Manual invocation Programmatic access with SDKs Local sessions Persistent sessions across requests Local access only Network-accessible from any service Who It's For Solo founders who use Claude Code daily and want to use it in toolchains who use Claude Code daily and want to use it in toolchains Backend developers adding AI capabilities to services and APIs adding AI capabilities to services and APIs AI tinkerers building agentic workflows, automation, and experiments building agentic workflows, automation, and experiments Data engineers who need structured, typed LLM output in pipelin...
