workflow-use 0.2.8

Create, edit, run deterministic workflows

Workflow-Use

Semantic browser automation with deterministic workflow generation and variables.

Quick Start

1. Test Deterministic Workflow Generation (NEW!)

python examples/scripts/deterministic/run_complete_test.py

Generate workflows without LLM for step creation - 10-100x faster, guaranteed semantic steps.

2. Create Your Own Workflow

from workflow_use.healing.service import HealingService
from browser_use.llm import ChatBrowserUse

llm = ChatBrowserUse(model_name="bu-latest")
service = HealingService(llm=llm, use_deterministic_conversion=True)

workflow = await service.generate_workflow_from_prompt(
    prompt="Go to GitHub, search for browser-use, get star count",
    agent_llm=llm,
    extraction_llm=llm
)

3. Run a Workflow

cd /path/to/workflow-use/workflows
python cli.py run-workflow-no-ai my_workflow.json

# If the workflow has variables, the CLI will prompt you interactively:
# Enter value for repo_name (required, type: string): browser-use

Key Features

🚀 Deterministic Workflow Generation

• Direct Action Mapping: input_text → input step (no LLM)
• Guaranteed Semantic Steps: 0 agent steps (instant execution, $0/run)
• 10-100x Faster: 5-10s vs 20-40s for LLM-based
• 90% Cheaper: Minimal LLM usage

🎯 Semantic-Only Multi-Strategy Element Finding

• No CSS/XPath: 100% semantic strategies (text, role, ARIA, placeholder, etc.)
• 7 Fallback Strategies: text_exact → role_text → aria_label → placeholder → title → alt_text → text_fuzzy
• Works WITH Browser-Use: Finds element index in DOM state, then uses browser-use's controller
• Fast & Robust: Direct index lookup when strategies match, falls back to AI when needed
• Human-Readable: Workflow YAML contains semantic strategies, not brittle selectors

🔄 Variables in Workflows

• Reusable Workflows: Parameterize dynamic values
• Semantic Targeting: Use {variable} in target_text
• Auto-Extraction: LLM suggests variables automatically

Comparison: Deterministic vs LLM-Based

Feature	Deterministic	LLM-Based
Generation Speed	⚡ 5-10s	🐌 20-40s
Generation Cost	💰 $0.01-0.05	💸 $0.10-0.30
Agent Steps	✅ 0 guaranteed	❌ Variable
Deterministic	✅ Yes	❌ No
Execution Speed	⚡ Instant	🐌 5-45s
Execution Cost	💰 $0/run	💸 $0.03-0.30/run

Recommendation: Use deterministic for most workflows (search, click, input, navigate).
