Physion is a free browser-based 2D physics simulator. Draw rigid bodies (circles, rectangles, capsules, polygons, gears, text and polylines), connect them with joints and springs, then simulate liquids, soft bodies and particle emitters. Boolean shape operations and a scriptable laser raycast are built in. Any object can carry a JavaScript node script, so scenes can react to collisions, measure themselves or drive their own motors.

Nothing to install: it runs in the browser, which is what makes it usable on locked-down school hardware and Chromebooks.

Free to use, with optional paid plans.

    Physion includes interactive features that enable users to manipulate objects and parameters in real-time to observe different outcomes from experiments.
  • Community Resources
    The platform has an active community that shares tutorials, simulation models, and problem-solving tips which enhances the learning process.

CodeFast features and specs

  • Rapid Project Launch
    CodeFast is designed to help developers and entrepreneurs ship projects quickly, providing boilerplate code and templates that significantly reduce the time from idea to a working product.
  • Built for Indie Hackers & Solopreneurs
    The platform is tailored for solo developers and indie hackers who want to build and launch SaaS products, side projects, or startups without a large team, offering practical and actionable content.
  • Next.js & Modern Stack Focus
    CodeFast focuses on modern, in-demand technologies like Next.js, React, and related tools, ensuring learners are building skills with widely-used and relevant frameworks.
  • Community & Support
    CodeFast provides access to a community of like-minded builders and entrepreneurs, offering peer support, networking opportunities, and motivation to keep shipping products.
  • Comprehensive Starter Templates
    The platform offers ready-to-use starter kits and boilerplates that include authentication, payments, database setup, and other common SaaS features, saving significant development time on repetitive tasks.

Possible disadvantages of CodeFast

  • Premium Pricing
    The course and starter kits come at a significant cost, which may be prohibitive for beginners, hobbyists, or developers in lower-income regions who are just starting out.
  • Opinionated Tech Stack
    CodeFast is heavily focused on a specific tech stack (primarily Next.js), which may not suit developers who prefer or need to work with other frameworks like Vue, Angular, or different backend technologies.
  • Not for Complete Beginners
    The content assumes a baseline level of programming knowledge. Absolute beginners with no coding experience may find it difficult to follow along without prior foundational learning.
  • Dependency on Templates
    Relying heavily on boilerplate code and starter kits can limit deeper understanding of the underlying technologies, potentially leaving developers unable to troubleshoot or customize beyond the provided templates.
  • Limited Depth on Advanced Topics
    Because the focus is on shipping fast, some advanced software engineering concepts like scalability, testing, architecture patterns, and security best practices may not be covered in sufficient depth.

Analysis of CodeFast

Overall verdict

  • CodeFast is a well-regarded coding bootcamp-style course created by Marc Lou, aimed at teaching people how to build and ship web apps quickly, particularly for indie hackers and entrepreneurs rather than traditional software engineering career paths.

Why this product is good

  • Created by Marc Lou, a successful indie hacker with multiple profitable SaaS products, lending credibility to the practical approach taught
  • Focuses on speed and shipping real projects rather than deep theoretical computer science concepts
  • Teaches a modern, practical tech stack (Next.js, React, etc.) that's directly applicable to building SaaS products
  • Community access allows students to network with other builders and get support
  • Emphasis on building an actual portfolio of shipped products rather than just completing exercises
  • Regularly updated content to keep pace with changing web development practices

Recommended for

  • Aspiring indie hackers who want to build and launch their own SaaS products
  • Entrepreneurs with business ideas who need technical skills to build MVPs themselves
  • Non-technical founders looking to become technical enough to ship products without hiring developers
  • People who prefer project-based learning over traditional computer science curricula
  • Those specifically interested in the Next.js/React ecosystem for web app development
  • Self-motivated learners who want a fast-track path to shipping products rather than a comprehensive CS education

  • Time flies, because we're spending almost a quarter of each day scrolling
    'time scrolling by' with alias of clock time displayed everytime 'enter'/'return' pressed[0a][0b] would seem a bit easier to do than pop-up physics demo with 'clock displaying time flying through demo virtual space[1]. Although the later is bit more visually presentable/interesting.
