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 250 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.

Blazor features and specs

  • Single Language
    Blazor allows developers to use C# for both client-side and server-side development, reducing the need to switch between different languages and enhancing developer productivity.
  • Full-Stack Development
    With Blazor, developers can build full-stack web applications using .NET, leveraging the vast .NET ecosystem and tools.
  • WebAssembly Support
    Blazor WebAssembly enables running C# code directly in the browser, allowing for rich interactive web applications with less reliance on JavaScript.
  • Reusability
    Blazor promotes code reusability by allowing shared code between server and client-side applications.
  • Components-Based Architecture
    It uses a component-based architecture that facilitates easier maintenance of code and enhances modularity.

Possible disadvantages of Blazor

  • Performance Limits
    Blazor WebAssembly can have slower performance compared to JavaScript due to its intermediated execution through WebAssembly.
  • Download Size
    Blazor WebAssembly applications can have larger initial download sizes, which can affect load times and user experience.
  • Newness
    As a relatively new technology, the Blazor community is still growing, which can sometimes limit the availability of third-party tools and resources.
  • Limited Browser Support
    Some older browsers do not support WebAssembly, potentially reducing the reach of Blazor applications if not accounted for.
  • Learning Curve
    Developers familiar with JavaScript frameworks may encounter a learning curve when transitioning to Blazor and the .NET ecosystem.

Questions & Answers

As answered by people managing Blazor 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.
