Basic Information

GenSX is a TypeScript framework and workflow engine for building complex LLM applications, agents, chatbots, and long-running workflows. It provides a programming model where workflow components are pure TypeScript functions that are easily composed to express tasks and agent behaviors. The repo hosts the core framework, published packages, example applications, and website resources intended for developers who want to build stateful, testable, and type-safe AI-driven workflows. GenSX emphasizes natural composition of components rather than graph-based DSLs, and it supports scaling from simple functions to advanced agent patterns such as reflection and long-running processes. The project also includes examples illustrating common use cases like RAG, blog writing, research pipelines, chat memory, and integrations with providers like OpenAI and Vercel AI.

App Details

Features
GenSX highlights include pure function components for testability and reuse, natural composition of components to build workflows, and full TypeScript type safety without special DSLs. The framework offers automatic real-time tracing of component inputs, outputs, tool calls, and LLM calls for observability and debugging. It supports one-click deployment of workflows as REST APIs optimized for long-running LLM workloads up to 60 minutes. Built-in storage options include zero-config blob storage, SQL databases, and vector search to enable stateful agents and retrieval-augmented generation. The repository also contains numerous example projects demonstrating patterns such as reflection, RAG, blog writing, hacker news analysis, text-to-SQL, and chat memory to help users get started.
Use Cases
GenSX helps developers create, test, and deploy LLM-powered applications by offering a simple, type-safe function-based programming model that scales to complex agent patterns. Pure components make code easy to unit test and reuse, while composition simplifies building multi-step workflows like research-to-draft pipelines. Built-in tracing and observability reduce debugging time by surfacing component inputs, outputs, and LLM interactions. Integrated storage and vector search make it straightforward to build stateful agents and retrieval-augmented generation. Example applications and a quickstart guide accelerate onboarding, and one-click deployment enables turning workflows into REST APIs suitable for long-running tasks. The monorepo structure centralizes packages, examples, and website documentation to support development and contribution.
