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 — 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 — 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
