RepRaptor is a community workout app for building, sharing, and running training programs. Publish a program to the discovery feed and anyone can find it and run it. Browse what the community has built, follow a program from your coach, or start from an official template.

Build two kinds of training. Classic programs run on weeks, days, exercises, sets, and rest for strength blocks, hypertrophy, and periodized plans. Circuit programs run on timed rounds for HIIT, EMOM, AMRAP, Tabata, and finishers. Every exercise pulls from a library of 1,796 moves, already tagged and searchable by muscle, equipment, or category, and you can edit any of them.

Coaches get a full platform. Build programs for clients, message them inside the app, bundle plans together, and share links that track which channel sends signups. An activity feed shows who's training and flags anyone quiet for a week. Pricing is flat with no fees per client.

Free for lifters. On iOS and web, with Android coming.

StackBlitz features and specs

  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.
  • WebContainers
    StackBlitz uses WebContainers to run Node.js applications in the browser, providing a near-native development experience.
  • Collaboration
    Real-time collaboration features allow multiple users to work on the same project simultaneously, similar to Google Docs.

Possible disadvantages of StackBlitz

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.

Questions & Answers

As answered by people managing StackBlitz and RepRaptor.

What makes your product unique?

RepRaptor's answer:

RepRaptor does two things and skips the rest. You build training programs and you run them. No social feed, no marketplace taking a cut, no per client billing. Coaches pay one flat monthly rate no matter how many clients they carry. The same app handles structured strength blocks and timed circuits, and anyone can publish a program to the community for others to run.

Why should a person choose your product over its competitors?

RepRaptor's answer:

Most coaching platforms charge per client or take a percentage of what you earn. RepRaptor is built the other way:

  • Flat pricing. One monthly rate by client capacity, so growing your roster never raises your cut.
  • Free for lifters. Clients use the full app at no cost, which makes onboarding easy.
  • Two builders in one. Linear programs and timed circuits, so you are not locked into a tool that only does one.

What's the story behind your product?

RepRaptor's answer:

Training apps kept piling on things that had nothing to do with training. Social feeds, badges, upsells, per client fees that punished coaches for growing. RepRaptor started as the opposite. Strip it down to building and running programs, keep lifters free, and charge coaches one flat rate. It is built by a solo developer who wanted a clean tool for finding and following good programs.

How would you describe the primary audience of your product?

RepRaptor's answer:

RepRaptor serves two main groups, plus the creators who sit between them:

  • Coaches and personal trainers. Online and in person, from solo trainers up to small gyms, who build programs and deliver them to clients.
  • Lifters. People who want to follow a solid program and track their training without a cluttered app.

Creators sit in between, publishing programs to the community for anyone to run.

Which are the primary technologies used for building your product?

RepRaptor's answer:

  • Frontend. Vue and Pinia, styled with Tailwind.
  • Mobile. Capacitor, one codebase for iOS and Android.
  • Backend. Supabase, which is Postgres with row level security, plus AWS Lambda for serverless functions.
  • Payments. Stripe on web, RevenueCat on mobile.

  1. Has almost everything I need

    I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

    Competitors: replit
    Pros:    Easy to get started and operate|Fast|Supports common extensions|Works with most npm packages
    Cons:    Still not as good as local development|Can be hard to debug|Build times can be slower than local

  • RS-X: Framework-agnostic reactive state and expressions for JavaScript/TS
    Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 7 months ago
  • Show HN: I combine Htmx, LiveView and SolidJS for interactive server components
    I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 10 months ago
