What Is code2flow and What Does It Do?

Updated

code2flow (app.code2flow.com) is a browser-based tool that turns pseudo code into flowcharts automatically. You type or paste code-like logic, and it renders a diagram you can export as SVG, PNG, or PDF. It fits anyone who needs to visualize program logic quickly — developers documenting a function, analysts sketching a decision tree, or teams embedding diagrams in JIRA and Confluence.

What the tool actually does

The core job is conversion, not drawing. You don't place shapes or drag connectors; you describe logic in a syntax close to real code, and the tool lays out the flowchart for you.

  • Input: pseudo code written in a code-like style (conditions, loops, calls).
  • Action: the converter parses that text and generates a flowchart.
  • Result: an interactive diagram in the browser that you can refine and export.

Because the diagram is generated from text, updating the logic means editing the text — the layout follows.

Who it's for

User Why it helps
Developers Document control flow without manual diagramming
Technical writers Keep diagrams in sync with described logic
Product / business analysts Sketch decision paths and processes fast
Teams using JIRA / Confluence Embed generated diagrams where work is tracked

Key capabilities

  • Automatic generation from pseudo code — no manual shape placement.
  • Interactive editing in the browser.
  • Export formats: SVG, PNG, and PDF.
  • Integrations: plugins for JIRA and Confluence.
  • Access: runs online, so no local install is required to start.

Pricing and access

The site advertises an unlimited free trial, and Stripe is listed as a payment platform. The available information does not specify paid tier prices or whether any features are gated behind login, so treat those as unconfirmed rather than assuming everything is free or fully open.

When to use it — and when not to

Use it when your goal is to communicate logic clearly and you'd rather write it than draw it, or when you need a diagram you can drop into documentation or a JIRA/Confluence page.

Consider alternatives when you need pixel-level control over layout, or you're diagramming something that isn't logic-driven (org charts, network topology, freeform sketches). Text-to-diagram tools are strongest when the structure comes from code-like rules.

Getting started

  1. Open app.code2flow.com in a browser.
  2. Enter your pseudo code in the input area.
  3. Let the tool generate the flowchart and adjust the text as needed.
  4. Export to SVG, PNG, or PDF, or embed via the JIRA/Confluence plugins.

The main thing to verify early is how your pseudo code syntax maps to shapes — small syntax choices change the generated diagram, so test a short snippet before writing a long one.
