opencode-runtime 0.5.0

Embed OpenCode in your Python application.

opencode-runtime

Embed OpenCode in your Python application.

OpenCode is a great CLI coding agent. But to embed it in a product, SaaS backend, or multi-user automation system, you need more than a CLI process.

opencode-runtime turns OpenCode into a managed application runtime for Python. It uses OpenCode as the agent harness and adds what you need to run it as part of an application: lifecycle management, per-user workspaces, reusable sessions, health checks, streaming output, and multi-server orchestration.

Install

pip install opencode-runtime
npm install -g opencode-ai   # opencode must be on PATH

Use

Your first session

from opencode_runtime import OpenCodeRuntime

async with OpenCodeRuntime() as r:
    session = await r.session()
    response = await session.ask("Explain this repo")
    print(response.text)

One server per user, automatically

Every (workspace, user_id) pair gets its own isolated server, workspace, and conversation history — started on first use, reused after:

async with OpenCodeRuntime(runtime_dir=".opencode-runtime") as r:
    s1 = await r.session(workspace="org_a", user_id="u_1")
    s2 = await r.session(workspace="org_b", user_id="u_2")

Stream every token as it arrives

async for event in session.stream("Review this PR"):
    if event.type == "message.part.delta" and event.text:
        print(event.text, end="", flush=True)

Inspect

Servers started from Python are visible and manageable from the terminal:

opencode-runtime ps

  ID                  PID    PORT    STATUS      UPTIME    WORKSPACE   USER    PROJECT
  ───────────────────────────────────────────────────────────────────────────────────

  81fa29acb3e9210f   12088   58411   ● running   3m        org_b       u_2     ~/Developer/myproject

Guides

• OpenCode config — models, permissions, agents, skills
• Sessions — continuation, resume across restarts
• Users & workspaces — multi-tenant isolation
• Streaming — event types, tool calls, permissions, cost
• CLI — manage your fleet from the terminal
• HTTP client — direct server access

Requirements

• Python 3.10+
• opencode 1.0+ on PATH
