Features and specs

What each product offers, as listed by its team.

Code Diagram 5 features
BonHand 13 features
  • Visual Code Understanding
    Code Diagram helps developers visualize their codebase through auto-generated diagrams, making it easier to understand complex code structures, relationships, and architecture at a glance.
  • IDE Integration
    The tool integrates directly with popular development environments like VS Code, allowing developers to create and view diagrams without leaving their coding workflow.
  • Automatic Diagram Generation
    Code Diagram can automatically generate diagrams from existing code, saving significant time compared to manually creating and maintaining architecture documentation.
  • Improved Documentation
    By providing visual representations of code structure, it helps teams maintain up-to-date documentation that is easier to share and understand, improving collaboration among team members.
  • Support for Multiple Diagram Types
    The tool supports various diagram types such as class diagrams, sequence diagrams, and dependency graphs, giving developers flexibility in how they visualize different aspects of their codebase.

Possible disadvantages

  • Limited Language Support
    Code Diagram may not support all programming languages equally, potentially leaving developers working in less popular or niche languages without full functionality.
  • Learning Curve
    Despite being visual, users may still need time to learn how to effectively use the tool, configure diagram settings, and interpret the generated visualizations properly.
  • Performance with Large Codebases
    Generating diagrams for very large or complex codebases can be slow or produce cluttered, hard-to-read visualizations that require significant manual adjustment.
  • Limited Free Tier
    The tool may have restrictions on its free plan, requiring a paid subscription to access advanced features, which can be a barrier for individual developers or small teams on tight budgets.
  • Diagram Customization Constraints
    Auto-generated diagrams may not always match the exact layout or style preferences of users, and customization options may be limited compared to dedicated diagramming tools like draw.io or Lucidchart.

Questions & Answers

As answered by people managing Code Diagram and BonHand.

What makes your product unique?

BonHand's answer:

BonHand is built for one person running their own practice, not a tuition centre or a studio with staff. It doesn't change how you talk to clients: you keep WhatsApp, email, calls and lessons as they are, and BonHand keeps the record behind them. Each client gets one page with sessions, payments, notes and a running balance, and the dashboard shows what needs doing today. Group sessions track attendance and payment per person. Clients pay you directly through your own payment link, so BonHand never takes a cut. It works in English and Traditional Chinese, and it's free for up to 5 clients.

Why should a person choose your product over its competitors?

BonHand's answer:

Most tools in this space are built for centres and studios, with online booking, card checkout and staff accounts. If you work alone and clients already pay you by bank transfer, FPS or PayMe, you'd be paying for features you won't use. BonHand focuses on the record: who attended, who has paid, what you agreed and what to send next. Payment reminders list each unpaid session and the total, and AI can draft a post-session update from your notes that you edit and send yourself. It's free for up to 5 clients with no card, and paid plans start at $29 a month. If you need online self-booking, card payments or invoicing, a tool like TutorBird or My Music Staff will suit you better.

How would you describe the primary audience of your product?

BonHand's answer:

Independent professionals who teach or train one to one or in small groups and run the business side themselves: private tutors, music teachers, personal trainers, language tutors and coaches. Typically someone with a handful to a few dozen regular clients, keeping track of sessions, payments and updates to clients or parents across chats and a diary. BonHand works in English and Traditional Chinese, handles fees in 11 currencies, and is aimed first at Hong Kong and the UK.

Which are the primary technologies used for building your product?

BonHand's answer:

Laravel, Livewire, Alpine.js and Tailwind CSS on PostgreSQL, hosted on Laravel Cloud behind Cloudflare. Stripe handles subscriptions. Update drafts use OpenAI and Anthropic models through Laravel's AI SDK. It runs in the browser and can be installed to the home screen.

What's the story behind your product?

BonHand's answer:

BonHand was started by Dollie PoYan Wong, an academic tutor who spent years teaching primary and secondary students preparing for local exams, mostly online. At her busiest, every slot in her week had a student in it, and she ran it all on a chat app, a paper diary and a spreadsheet. Lessons moved in the chat while the diary kept the old time, make-up lessons were owed and forgotten, and working out and chasing each family's fees took more and more of her evenings. The tools she found were made for salons, clinics and studios with staff, and were too costly or too complex for one person. So she built BonHand for a single person with a full week. The full story is at https://bonhand.com/why

Who are some of the biggest customers of your product?

BonHand's answer:

  • Private tutors
  • Music teachers
  • Personal trainers
  • Language tutors
  • Freelance service providers with regular clients
