RepDB is a one-time-purchase exercise dataset for developers building fitness and workout apps โ€” not a subscription, not a rate-limited API. You download the data once and own it: JSON (and SQLite on the higher tier), WebP images, and full EN/DE/ES translations, with no per-request billing and no dependency on our servers staying up.

A free tier includes 400 exercises with flat-style 512ร—512 images, attribution-licensed for commercial in-app use. The Starter tier ($199) adds the full catalog in classic white-background style. Standard ($399) adds transparent 1024px images, looping animations, exercise relations (similar/progressions/regressions), workout templates, and embeddings โ€” exclusive to that tier.

Every exercise includes muscle-group highlighting, equipment/muscle icons, MET values, and safety/goal tags. Compared to GIF- or JPG-based competitor APIs, RepDB images are transparent WebP with no watermarks, so they drop into any app UI without a white box around them.

Backendless features and specs

  • Codeless Development
    Backendless offers a 'Codeless' feature, which allows users to build backend logic without writing any code. This is particularly beneficial for those who are not familiar with complex coding languages.
  • Real-Time Database
    The platform provides real-time data synchronization, allowing applications to update data instantly across all clients. This is essential for interactive applications such as chat apps and real-time data feeds.
  • API Services
    Backendless allows the creation of REST and SOAP APIs effortlessly. This makes it easier to integrate with other services and provides a clear pathway for extending app functionality.
  • User Management
    The platform comes with built-in user management features such as registration, login, password recovery, and social logins. This helps in reducing the effort required to implement user authentication and authorization.
  • Mobile and Web App Support
    Backendless supports both mobile (iOS/Android) and web applications, offering SDKs for multiple platforms which streamlines the development process.

Possible disadvantages of Backendless

  • Pricing
    Although Backendless offers a free tier, many features and higher usage levels are locked behind a paywall. This may be prohibitive for startups or small projects with limited budgets.
  • Learning Curve
    Even though Backendless offers codeless development, mastering the platform as a whole can be challenging for beginners. There are many features and settings that require some time to understand fully.
  • Vendor Lock-In
    Relying too much on Backendless-specific features can create difficulties if you decide to migrate to another backend service in the future. The migration process can be complex and time-consuming.
  • Limited Customization
    While Backendless offers many out-of-the-box features, there can be limitations in terms of customizing the backend behavior in comparison to building a custom backend.
  • Community and Support
    The community around Backendless is smaller compared to more established backend solutions like Firebase. This can make finding community support, third-party plugins, or comprehensive tutorials harder.

Questions & Answers

As answered by people managing Backendless and RepDB.

What makes your product unique?

RepDB's answer:

RepDB is sold as a one-time download, not a metered API โ€” you own the JSON/SQLite data and WebP images outright, with no rate limits, no per-request billing, and no risk of the vendor cutting off access. It's also the only dataset in this space with EN/DE/ES translations, transparent (alpha-channel) images with no watermark, muscle-group highlighting, safety/goal tags, and looping animations on the higher tier.

What's the story behind your product?

RepDB's answer:

RepDB grew out of a consumer workout app its creator was building solo. Sourcing exercise images and data meant either paying for a subscription API with usage caps and no caching rights, or producing everything from scratch. The illustrated, multi-language dataset was built for us first, then split out as its own product once it became clear other indie developers had the same problem and preferred to buy the data outright rather than rent it through an API.

Why should a person choose your product over its competitors?

RepDB's answer:

Most alternatives are subscription APIs โ€” you pay monthly, you're capped on requests, and ExerciseDB's terms of use explicitly forbid caching or storing the data at all, so every image render is a live paid API call. RepDB is the opposite: pay once, download the files, self-host with zero ongoing dependency. It's also the only option offering true DE/ES localization and transparent images instead of a white box behind every exercise.

How would you describe the primary audience of your product?

RepDB's answer:

Solo developers and small teams building fitness or workout-tracking apps (iOS, Android, web) who need licensed exercise images and structured exercise data, but don't want to build their own media pipeline or depend on a rate-limited third-party API.
