Vektir Flow is a visual dataflow and process diagramming tool built for data engineers. Build pipeline diagrams on a code-first canvas and export to formats your team can actually use.

Features

Everything a data engineer needs to diagram.

Not a generic flowchart tool repurposed for data work. Built specifically for pipeline diagrams, data flows, and system architecture.

Visual canvas with code panel

Drag and drop nodes on a live canvas while the Mermaid code updates in sync. Edit either side — they stay in lock-step.

Mermaid-native import & export

Paste any Mermaid flowchart and it renders instantly. Export back out as .mmd — a plain text file that lives in your repo.

Export to PNG and SVG

One-click export to PNG or SVG for Confluence, Notion, Slack, or anywhere else you need a static image that doesn't require the tool to render.

All Mermaid flowchart node types

Rectangles, cylinders (databases), rhombuses (decisions), rounded nodes, subroutines — the full Mermaid flowchart spec, accessible from the canvas without writing syntax.

No account required

Open the URL, start diagramming. No sign-up, no login, no trial. Your work stays in your browser until you choose to export it.

Git-friendly output

Because Mermaid is plain text, your diagrams can live in a /docs folder, get code-reviewed in a PR, and be diffed line by line.

Use cases

What data engineers actually use it for.

Vektir Flow handles the diagrams that show up most in data engineering work.

Pipeline

Data pipeline and ETL/ELT diagrams

Map source systems → ingestion → transformation → warehousing → serving in a single diagram. Show where data moves and where it can break.

Architecture

Data platform architecture

Document your Kafka topics, Spark jobs, dbt models, and Snowflake layers in one diagram that lives in the repo alongside the code.

Incident

Incident and failure mode diagrams

During an outage, sketch what you know and what you're investigating. Export the final diagram into your postmortem doc.

Docs

Living documentation in your repo

Commit architecture/pipeline.mmd to your repo. It renders in GitHub and stays in sync with your actual codebase.

The output

Plain text you own forever.

Every diagram you create in Vektir Flow outputs to Mermaid — a plain-text format that renders natively in GitHub, Notion, GitLab, and most modern documentation tools.

No binary blobs, no proprietary formats, no "export to PDF and pray" workflows. A .mmd file is just text. Commit it, diff it, generate it from code, or feed it to an LLM.
