## Code to Flow

Reading someone else's code — or your own code from six months ago — is one of the slowest parts of software work. Code to Flow compresses that process by turning a text snippet into a visual graph. The AI parses the structure and logic, then renders an interactive flowchart you can zoom, pan, and edit, with a parallel explanation panel describing the reasoning in words rather than symbols.

The tool goes beyond a single diagram type. Alongside control flow it can produce sequence diagrams for interactions, class diagrams for object structure, and user-journey views, which makes it useful both for debugging a gnarly function and for documenting architecture in a review or a spec. Diagrams can be exported as PNG, SVG, or PDF, and shared via a link.

Code to Flow runs entirely on pasted snippets and states that your code is never stored — it is processed to build the diagram and then discarded, which matters if you work under confidentiality constraints. The free tier covers three flowcharts per day, and a one-time or monthly upgrade removes the daily cap and ads. At the time of review the site reports more than 500,000 flowcharts generated.

**Pricing & Plans:** Freemium. Up to 3 flowcharts per day are free. Unlimited access is offered as a one-time lifetime purchase or a monthly subscription, both removing ads and raising the token limit. Prices are listed on the pricing page and may change.

- **Code-to-flowchart conversion:** Paste a snippet in Python, JavaScript, TypeScript, Java, C, C++, Go, Rust, and others to get an interactive diagram of its logic.
- **Multiple diagram types:** Generate flowcharts, sequence diagrams, class diagrams, and user-journey views depending on what you need to explain.
- **AI code explanations:** A written explanation accompanies each diagram so you can verify the AI's reading of the logic against your own.
- **Export and share:** Download results as PNG, SVG, or PDF, or share a link to the diagram with teammates and reviewers.

**Strengths:** Turns dense code into a readable visual in seconds rather than minutes of manual tracing; Supports the common programming languages and several diagram types in one tool; Explanations make the diagram self-checking rather than an opaque picture; States that code is never stored, which suits confidential work; free tier available

**Limitations:** Very large files may exceed the token limit on lower tiers; No interactive editor for deep diagram customization beyond basic edits; The daily free cap of three flowcharts is limiting for heavy use

## OpenFlowKit

OpenFlowKit is an open-source diagramming studio built for engineers who think in systems. It supports three ways of working on one canvas: freehand drawing with shapes, connectors, ink, images and charts; writing the diagram as code in Mermaid, D2 or Structurizr; or letting an AI agent build and edit it live through the Model Context Protocol. Text and canvas stay in sync, so you can start with a snippet and finish with something visual.

A standout v2 feature maps a public GitHub repository directly in the browser: paste an owner/repo URL and OpenFlowKit reads the files, produces boxes and connections, and cites each arrow back to the exact line of code it came from. Private repositories can be mapped locally through the CLI. The result is architecture documentation that reflects the code rather than someone's memory of it.

OpenFlowKit is also practical for day-to-day diagramming: a toolset of 29 MCP tools for agents, C4 context/container/component views that stay connected to one underlying model, automatic matching of 2,000+ cloud and developer icons by node label, animated SVG/GIF/MP4 export, share links and self-hosting. It is MIT licensed, runs locally by default and needs no account.

**Pricing & Plans:** Free and open source under the MIT licence. There is no paid tier on the site; you can start creating without signing up, and the code can be self-hosted.

- **Repo-to-map generation:** Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from.
- **Agent-native canvas over MCP:** 29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away.
- **Diagram as code:** Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals.
- **Connected C4 model views:** Move from system context to containers to components in linked views that all stay grounded in a single architecture model.
- **Icon matching and motion export:** Label a node 'PostgreSQL' or 'Kubernetes' and the right icon is matched automatically from 2,000+ cloud and developer icons; export animated SVG, GIF, MP4 or WebM for living documentation.

**Strengths:** Free, MIT-licensed and local-first with no account required; Unique repo-to-diagram mapping that cites each connection back to code; Works equally well for hand drawing, diagram-as-code and AI-agent workflows; Strong ecosystem coverage with automatic matching of 2,000+ cloud and developer icons

**Limitations:** No hosted paid support or managed cloud option is advertised, so teams self-host; Advanced MCP and CLI repo mapping assumes comfort with developer tooling; C4 model depth and multiple views can feel heavy for quick one-off sketches
