What it is

Symphony is OpenAI's open-source agentic coding framework released in March 2026. It turns software project work into isolated, autonomous 'implementation runs' — instead of supervising an AI coding agent, you define tasks in your issue tracker and Symphony dispatches parallel agents to each one in an isolated environment. Built on Elixir/BEAM for fault tolerance and concurrent agent management. Uses a WORKFLOW.md file in your repo as the agent's instruction set.

When it fits — and when it doesn’t

A good fit for

  • Engineering teams who want to delegate batches of issues or features to autonomous coding agents without babysitting each run

Look elsewhere if

  • Teams needing real-time collaboration with agents or those not yet using Linear/GitHub Issues as their workflow

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

No verified weaknesses on file yet. That’s a gap in our data, not a clean bill of health.

What it does well

  • Isolated implementation runs

  • Parallel agents

  • WORKFLOW.md config

  • Linear integration

  • Elixir/BEAM runtime

  • Apache 2.0

  • Engineering preview
