## 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

## CRUDERRA

CRUDERRA takes aim at a universal engineering tax: documentation that is accurate the day it is written and misleading a sprint later. Instead of asking developers to hand-draw diagrams and maintain wikis, it reads the repository itself. Point it at a Java, Python or Go codebase and it reconstructs the architecture — services, databases, queues and the links between them — in roughly a second.

Output is treated as code. Generated documentation lives in Git beside the repository and is reviewed like any other change, so it is versioned, diffable and refreshed automatically on every commit. Teams get an interactive architecture graph plus standard C4, DFC and UML diagrams, and can export machine-readable OpenAPI and AsyncAPI specs for their services.

The practical payoff is speed: full documentation in about a second rather than days, diagrams rebuilt from real code instead of drawn by hand and forgotten, and onboarding measured in days rather than weeks because the whole system is visible on one canvas. CRUDERRA is positioned for enterprise stacks, currently supporting Java, Python and Go with more languages planned, and is sold through a demo-led process.

**Pricing & Plans:** No public price list. CRUDERRA is sold via a book-a-demo process, so commercial terms are discussed directly with the team.

- **Documentation from source in ≈1 second:** Point CRUDERRA at a repository and get complete documentation and architecture output almost immediately — no manual modelling required.
- **Live architecture graph:** An interactive map of services, data stores and dependencies, rebuilt from the actual code rather than from a stale diagram.
- **C4, DFC & UML diagrams:** Generate standard architecture and data-flow diagrams directly from your repositories.
- **OpenAPI & AsyncAPI export:** Export machine-readable API specifications for your services in a single click.
- **Docs-as-code in Git:** Documentation is versioned next to the code, reviewed like any other change, and re-scanned on every commit.

**Strengths:** Cuts documentation effort from days to roughly a second per scan; Documentation stays in sync automatically because it is regenerated on every commit; Docs live in Git and go through normal code review; Supports the enterprise stacks teams actually run — Java, Python and Go — with standard C4/UML output and API spec export

**Limitations:** Output quality depends on code structure, and language support is currently limited to Java, Python and Go; Pricing is only available through a sales conversation, with no self-serve tier
