Open Multi-Agent

TypeScript multi-agent orchestration framework where a coordinator LLM decomposes a natural-language goal into a task DAG and distributes subtasks to specialized sub-agents, all runnable against local Ollama models or cloud providers.

About Open Multi-Agent

TypeScript multi-agent orchestration framework where a coordinator LLM decomposes a natural-language goal into a task DAG and distributes subtasks to specialized sub-agents, all runnable against local Ollama models or cloud providers.

Best for: Developers who want to build goal-directed multi-agent pipelines in TypeScript without writing orchestration boilerplate, and who need local-LLM support from the start rather than as an afterthought.

Deployment: npm package. Clone the repo or install as a dependency, configure an LLM provider (Ollama, Anthropic, OpenAI), and define your agent goals in TypeScript. No external infrastructure required for local-only use.

Skill level: Intermediate

Tradeoffs

Younger ecosystem than CrewAI or LangChain, with fewer pre-built agent templates and community integrations. TypeScript-only; Python shops will need a separate solution or bridge layer. Coordinator-based planning adds latency on initial decomposition vs. hand-coded pipelines. Best for greenfield TypeScript projects rather than retrofitting existing codebases.

Best for

Developers who want to build goal-directed multi-agent pipelines in TypeScript without writing orchestration boilerplate, and who need local-LLM support from the start rather than as an afterthought.

Why use it

Open Multi-Agent is one of the few TypeScript-native agent orchestration frameworks with first-class Ollama support. The coordinator-plus-DAG model means you describe what you want done and the system figures out the parallel execution plan, unlike frameworks that require you to manually define the task graph. MIT license and active 2026 development make it a lower-risk foundation than newer experimental frameworks.

Key features

  • Goal-directed orchestration: describe a high-level goal in natural language; the coordinator agent decomposes it into a DAG of subtasks automatically
  • Local-LLM ready: first-class Ollama integration means the full multi-agent pipeline runs offline on your own hardware
  • TypeScript-native: full type safety across agent definitions, task schemas, and inter-agent message passing, with no Python bridge required
  • Provider-agnostic: swap between Ollama, Anthropic Claude, OpenAI, or other providers at the config level without changing agent code
  • Parallel task execution: the coordinator schedules independent subtasks to run concurrently, reducing total wall-clock time for complex goals

Common AI use cases

  • Build a research pipeline where a coordinator spawns a search agent, a summarizer agent, and a citation-checker agent running in parallel against a local Ollama model
  • Automate multi-step code generation workflows: planner agent decomposes a feature request, coder agents implement each module, reviewer agent checks output
  • Create self-hosted AI assistants that orchestrate multiple specialized tools (browser, code exec, file I/O) through a single goal-directed interface

Who should use it

  • TypeScript developers building agent-powered products who want local-LLM compatibility without adopting a Python framework
  • Teams that need parallelized, goal-directed AI pipelines and want to avoid writing manual orchestration logic
  • Privacy-conscious builders who want the full multi-agent experience running on-premise via Ollama

Who should not use it

  • Python-only shops: the framework is TypeScript-native with no official Python SDK
  • Projects needing a large pre-built agent library: Open Multi-Agent is a framework, not a plugin marketplace
  • Simple single-agent use cases where CrewAI, LangChain, or a direct Ollama API call is sufficient
