Why it is useful

Flowcharts for logic review, not diagram busywork.

Code and steps in

Paste simple JavaScript, TypeScript, pseudocode, text arrows, JSON, or Mermaid-lite syntax.

Clean flow out

Generate a readable SVG flowchart with start, process, decision, success, and error nodes.

Save and share

Keep diagrams in workspaces, share them by link, or export SVG and PNG assets.

Browser-native flowcharts for developer logic

Generate flowcharts from code, JSON, plain text steps, and Mermaid-lite arrows in a browser-native workspace built for developer logic review.

Why use it

Why use Flowchart Studio

Turn simple code branches, returns, and function calls into a readable flowchart without opening a heavy diagram editor.

Visualize JSON object and array structure as a parent-child diagram for API docs and payload reviews.

Convert plain text arrows or Mermaid-lite lines into a clean SVG diagram you can copy or download.

Save and share flowchart workspaces so teammates can reopen the same input, layout, and generated diagram.

How it works

How Flowchart Studio works

  1. 1

    Choose Code, Text steps, JSON, or Mermaid-lite mode and paste the logic you want to visualize.

  2. 2

    Use templates or generate instantly while the browser creates nodes, connectors, and a clean SVG preview.

  3. 3

    Switch layout direction, zoom for inspection, then copy SVG, download exports, or share the workspace link.

Use cases

Popular flowchart use cases

Review login, checkout, validation, API request, and error handling logic before implementation.Document JavaScript control flow with a lightweight code to flowchart generator.Turn JSON payload structure into a quick diagram for teammates or API documentation.Sketch product workflows with text arrows instead of dragging boxes around.Create shareable visual notes for pull requests, docs, onboarding, and debugging sessions.

FAQ

Flowchart Studio questions

Can I generate flowcharts from code?

Yes. Flowchart Studio handles simple JavaScript, TypeScript, and pseudocode patterns like if/else, return statements, function calls, and try/catch blocks.

Can I create flowcharts from text steps?

Yes. Use arrows such as Start -> Validate input -> Success to create nodes and connectors quickly.

Can I export the diagram?

Yes. You can copy SVG, download SVG, download PNG, and copy a Markdown embed from the studio.

Does it require a backend?

No. Flowchart generation, rendering, saving, sharing, and exporting all run in the browser.

Can I save and share flowcharts?

Yes. Flowchart Studio uses the same useSignal workspace system, so you can save locally or share a link that restores the same flowchart state.
