Vifu Python SDK

The Python SDK embeds the Vifu Runtime, Agent Gateway, and local Server. Python functions can become local Agent providers. Vifu("name") creates or reopens one real App in the personal Server and records its project binding in .vifu/app.json.

Create an environment and install Vifu:

python3 -m venv .venv
. .venv/bin/activate
python -m pip install vifu

The wheel contains the generated UniFFI binding, native Rust library, and Vifu Server binary. The Python API calls the Runtime in the application process. It reuses a running local Server or starts its bundled Server.

The public API provides:

  • Vifu for App identity, Agent registration, local Server connection, invocation, tracing, and remote calls.
  • VifuRuntime for persistent Runtime state, Agent registration, invocation, snapshots, and pending traces.
  • AgentTrace for activity, output deltas, and typed provider stages.
  • VifuGateway for explicit remote enrollment and advanced Gateway control.
  • VifuServer for advanced control of the bundled Vifu Server process.

Start with the Python tutorial. Runnable framework integrations are available for Google ADK and Foundry Local.
