ETL flow intelligence platform

You have hundreds of flows.
Read them as code.

Convert visual ETL flows to clean SQL, PySpark, or dbt models. Drop your flow file and get production-ready code.

The problem

Your flow library
is a black box

Every company accumulates ETL flows over the years. People build them, people leave, and the flows stay — but the knowledge doesn't.

When a new request comes in, nobody digs through 50 old flows to check if it's already been done. They build it again. Five versions of the same join, redundant maintenance, a flow library nobody trusts.

Deflows makes every flow readable, searchable, and optimizable.

What it does
01

Convert

Flows as code, anywhere

Generate clean SQL (PostgreSQL, MySQL) or PySpark from any flow. Code you can review, diff, put in Git, and run anywhere.

02

Analyze

Finally know what your flows do

Upload one flow or hundreds. See what each does: tables, joins, calculations, complexity. Read inherited flows without opening Prep.

03

OptimizePRO

Kill redundancy across your library

AI finds flows doing the same thing. Suggests consolidation. Generates optimized code. Cuts your flow count by 60%.

04

SearchPRO

Check before you build — every time

New request comes in? Search your library first. "Is there already a flow that joins orders and returns?" Find duplicates before you build them. Stop your library from growing out of control.

Use cases
Before you build

Check if it already exists

New request for a regional report? Search your flow library first. Deflows finds the 3 flows that already do something similar.

File stays in your browser

Your .tfl is parsed entirely in the browser. Only structural metadata (table names, joins, formulas) is sent for code generation — never the original file.

Connection hashing

Database addresses are hashed for grouping. We never see or store the originals.

No row data in .tfl

Prep files contain metadata only — table names, formulas, joins. Not your business data.
