What Is Forjinn? Visual AI Agent Builder
Forjinn lets you build, deploy, and manage AI agents and chatflows visually — connecting LLMs, tools, and data without writing code.
Forjinn is a visual AI agent builder that lets you wire together large language models, tools, memory, and data sources into working AI applications. You drag nodes onto a canvas, connect them, and deploy — no code required for most use cases. When you need custom logic, Forjinn exposes a REST API that integrates with any application.
What you can build
Forjinn organizes your work into a few core building blocks:
Chatflows
Conversational pipelines that connect an LLM to memory, document stores, and tools. Use these for chatbots, Q&A systems, and RAG applications.
Agent frameworks
Multi-agent workflows using LangFlow, CrewAI, AutoGen, or Google ADK. Agents can call tools, delegate tasks, and collaborate to complete complex goals.
Document stores
Upload documents, chunk and embed them, and build a vector index your chatflows and agents can search at runtime.
Triggers
Run flows automatically on a schedule or in response to incoming webhook events — no manual invocation needed.
Evaluations
Test your agents against datasets and custom metrics to measure quality before and after changes.
API gateway
A built-in LiteLLM-compatible proxy that lets you route requests to any LLM provider through a single unified endpoint.
Open source vs. full edition
Forjinn ships in two editions. The open source build is free to self-host and covers the core workflow capabilities. The full edition unlocks every feature.
