flow-forge-ai-sdk-ui 0.1.0

Debug UI for flow-forge-ai workflows.

flow-forge-ai-ui

Web UI for browsing and replaying flow-forge-ai workflow runs.

What It Does

• Connects to the runtime listener started by flow-forge-ai
• Displays a list of recorded runs and their steps/events
• Lets you trigger and monitor workflow replays from the browser

Requirements

• flow-forge-ai installed and configured with [runtime].enable = true
• The runtime listener must be reachable at the configured listener_host:listener_port

Installation

cd ui
pip install -e .

Or install via the ui extra from the core package:

cd core
pip install -e ".[ui]"

Starting the UI

flow-forge-ai-ui

By default the server listens on http://127.0.0.1:8080.

Options

flow-forge-ai-ui --host 0.0.0.0 --port 9090

Flag	Default	Description
-H / --host	127.0.0.1	Bind address
-p / --port	8080	Port

Configuration

The UI reads config.toml from the current working directory (the same file used by the core runtime). It uses the [runtime] section to locate the listener:

[runtime]
enable = true
listener_host = "127.0.0.1"
listener_port = 7070

Make sure the runtime listener is started before opening the UI. The core package starts the listener automatically when a workflow run begins inside an instrumented process.

Usage

1. Start your workflow in another terminal (the core runtime listener starts automatically):

   cd core/examples/02_ollama_workflow_decorator
   python example.py
   

2. Start the UI from the directory containing config.toml:

   flow-forge-ai-ui
   

3. Open http://127.0.0.1:8080 in your browser.

The UI shows all recorded runs. Select a run to inspect its steps and events, or trigger a replay.

API Routes

The UI itself is a thin FastAPI app that proxies requests to the core runtime listener. It exposes the following routes:

Method	Path	Description
GET	/	Main UI page (HTML)
GET	/api/runs	Proxy: list runs
GET	/api/steps	Proxy: list steps for a run
POST	/api/runs/{run_id}/replay	Proxy: start replay
GET	/api/runs/{run_id}/replay	Proxy: get replay status
DELETE	/api/runs/{run_id}/replay	Proxy: stop replay
