Complex systems became black boxes. Knowledge lived only in the minds of a few senior engineers. Onboarding new members took months instead of days. Architecture decisions were made without a clear picture of the existing system.

We created Archyl to solve these problems. By combining the proven C4 model with AI-powered discovery, we make it simple for any organization to gain complete visibility into their architecture and keep their documentation always up to date.

  • Cross-Device Accessibility
    Being an online platform, CodePen can be accessed from any device with an internet connection, making it convenient for developers on the move.

Possible disadvantages of CodePen

  • Limited Offline Functionality
    Since CodePen is primarily an online tool, it requires an internet connection for most of its features to work, limiting its usefulness in offline environments.
  • Performance Constraints
    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.
  • Security Concerns
    Sharing projects with the public can expose your code and assets to unauthorized use, posing potential intellectual property and security risks.

Archyl features and specs

  • AI-Powered Architecture Design
    Archyl leverages artificial intelligence to assist with architectural design processes, potentially speeding up the creation of floor plans, layouts, and design concepts significantly compared to traditional methods.
  • User-Friendly Interface
    The platform appears designed to be accessible to users who may not have extensive architectural training, making it easier for homeowners, developers, and designers to explore design possibilities.
  • Time Savings
    By automating aspects of the architectural design process through AI, Archyl can help reduce the time needed to generate initial design concepts and iterations, allowing for faster project turnaround.
  • Cost-Effective Design Exploration
    Using an AI-driven tool can reduce the cost of early-stage design exploration compared to hiring architects for multiple preliminary concepts, making architectural design more accessible.
  • Rapid Iteration
    The AI-powered platform enables users to quickly generate and modify multiple design variations, facilitating faster decision-making and allowing clients to visualize different options before committing to a final design.

Questions & Answers

As answered by people managing CodePen and Archyl.

What makes your product unique?

Archyl's answer:

Archyl is unique because it treats software architecture as a living, firstโ€‘class asset directly connected to your code, not a static diagram or forgotten Notion page.

Instead of being โ€œyet another diagramming toolโ€, Archyl focuses on the C4 model and automatically keeps architecture views synchronized with your repositories and services. That means:

  • Your diagrams and architecture docs are always aligned with reality (code, services, infra), not just with peopleโ€™s memory.
  • Architects and tech leads get a shared, opinionated model of the system (C4) that developers can actually use dayโ€‘toโ€‘day.
  • Architecture knowledge is captured and diffโ€‘able over time, like code, making it easier to onboard, review changes, and understand the impact of refactors.
  • Itโ€™s designed explicitly for modern, cloudโ€‘native, microservicesโ€‘heavy stacks, where traditional static documentation breaks down.

In short: Archyl doesnโ€™t just help you draw your architecture, it helps you continuously manage and evolve it alongside your codebase.

Why should a person choose your product over its competitors?

Archyl's answer:

Archyl is for teams who are tired of architecture that lives in slides and Notion pages, drifting out of sync with the code after every sprint.
