Airflow
Prefect

TransformDAGs to Flows

Point it at an Airflow DAG and get idiomatic Prefect code back. Raw source in, working flow out. Thirty seconds, not thirty hours.

# 1. Read the DAG source code
dag = read_dag("dags/etl_pipeline.py")

# 2. Look up Airflow→Prefect translation knowledge
mapping = lookup_concept("PythonOperator")
docs = search_prefect_docs("task retries")

# 3. LLM generates idiomatic Prefect code
# 4. Validate the generated flow
result = validate(
    original_dag=dag_path,
    converted_flow=prefect_code
)
# ✓ Syntax valid
# ✓ Both sources returned for comparison
Philosophy

Templates are brittle.
LLMs are adaptive.

Traditional conversion tools rely on rigid templates that break on the first edge case. We give the LLM raw source code and translation knowledge. It writes the Prefect code.

Template-Based

• Rigid pattern matching breaks on variations

• Non-idiomatic output requires manual fixes

• Cannot handle custom operators well

• Template maintenance burden

LLM-Assisted

• Source code + translation knowledge in, working code out

• Idiomatic Prefect, not templates with TODOs

• Handles custom operators and edge cases

• Gets better as models get better

Capabilities

Everything you need
to convert DAGs

DAG Reading
Read raw Airflow DAG source code directly. The LLM analyzes the code — no brittle AST intermediary.
Translation Knowledge
78 pre-compiled Airflow→Prefect mappings via Colin, plus live Prefect doc search for anything not covered.
Validation
Syntax-check generated flows and return both sources side-by-side for the LLM to verify structural fidelity.
Pattern Detection
Detect XCom usage, sensors, trigger rules, dynamic mapping, connections, variables, and custom operators.
Operator Mappings
50+ Airflow→Prefect operator mappings with example code and migration guidance for each pattern.
MCP Native
Built with FastMCP for AI-assisted workflows. Works with Claude, Cursor, and other MCP-compatible tools.
