ScreenForge

中文 | English

Describe what to test. Watch it happen. Get a pytest script.

ScreenForge is an AI-driven UI automation engine that turns natural language into executable test scripts. Unlike record-and-replay tools, you don't perform the actions yourself — the AI does it for you.

Why ScreenForge?

	Playwright Codegen	Browser Use	Midscene.js	ScreenForge
Need to perform actions yourself?	Yes	No	No	No
Generates replayable test scripts?	Yes	No	No	Yes (pytest)
Self-healing when UI changes?	No	No	No	Yes
Works as AI Agent tool (MCP)?	No	Yes	No	Yes

Core architecture: Your AI Agent is the brain (understands requirements, makes decisions). ScreenForge is the hands (executes UI actions, generates code).

Quick Start

pip install screenforge

# See the magic without any API key:
screenforge --demo

# For real usage, set your LLM key:
export OPENAI_API_KEY=sk-...

# Inspect the current page (returns DOM tree for your Agent to analyze):
echo '{"operation":"inspect_ui","platform":"web"}' | screenforge --tool-stdin

# Execute a single action:
screenforge --action click --platform web --locator-type text --locator-value "Login"

How It Works

You (or your AI Agent)          ScreenForge
        │                            │
        ├──── "Test the login" ─────►│
        │                            ├── inspect_ui (get DOM tree)
        │◄── DOM tree ──────────────┤
        │                            │
        ├──── click #email ─────────►│
        ├──── input "user@..." ─────►│
        ├──── click "Sign In" ──────►│
        │                            │
        │◄── pytest script ─────────┤
        │◄── Allure report ─────────┤

Each step: inspect → decide → act → verify. The AI decides, ScreenForge executes.

Features

• Cross-platform: Android (uiautomator2), iOS (wda), Web (Playwright)
• Self-healing engine: When tests break due to UI changes, the engine auto-repairs locators with confidence scoring and AST validation
• L1/L2 semantic cache: Same page + same instruction = instant response, no LLM call needed
• Visual fallback: When DOM can't locate elements (Canvas, games), VLM parses screenshots
• MCP server: Any MCP-compatible Agent can drive ScreenForge natively
• Structured output: JSON Lines events + report/runs/<id>/ artifacts for CI integration

Agent Integration (Claude Code / Cursor / Codex)

ScreenForge exposes itself as a tool for AI Agents. The standard loop:

# 1. Get page structure (your Agent analyzes it)
echo '{"operation":"inspect_ui","platform":"web"}' | screenforge --tool-stdin

# 2. Your Agent decides what to do, sends precise actions
screenforge --action click --platform web --locator-type text --locator-value "Login"

# 3. Verify the result, repeat
echo '{"operation":"inspect_ui","platform":"web"}' | screenforge --tool-stdin

For batch operations, use workflows:

screenforge --workflow ./workflows/login.yaml --platform web --json

Or start the MCP server for native Agent integration:

screenforge --mcp-server

GitHub Actions

Add ScreenForge to your CI pipeline:

- uses: jhinzzz/ScreenForge@v1
  with:
    platform: web
    workflow: ./workflows/login.yaml
    openai-api-key: ${{ secrets.OPENAI_API_KEY }}

Results are auto-uploaded as Allure artifacts. See action.yml for all inputs.

See Agent Integration Guide for the complete protocol.

Installation (from source)

git clone https://github.com/jhinzzz/ScreenForge.git
cd ScreenForge
python -m venv .venv && source .venv/bin/activate
pip install -e ".[all]"

Platform-specific extras:

• Web only: pip install -e . (default, includes Playwright)
• Android: pip install -e ".[android]"
• iOS: pip install -e ".[ios]"
• ML/cache: pip install -e ".[ml]" (sentence-transformers for semantic cache)

Configuration

# Required: LLM API key (OpenAI-compatible endpoint)
export OPENAI_API_KEY=sk-...

# Optional: custom endpoint (defaults to api.openai.com)
export OPENAI_BASE_URL=https://api.openai.com/v1

# Optional: model (defaults to gpt-4o)
export MODEL_NAME=gpt-4o

Or create a .env file (copy from .env_template).
