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.

Nim (programming language) features and specs

  • Performance
    Nim compiles to C, C++, or JavaScript, which can offer performance close to languages like C and C++. This makes it suitable for high-performance applications.
  • Expressive Syntax
    Nim offers a clean and expressive syntax that is inspired by Python, making it relatively easy to write and read code, which can speed up development.
  • Metaprogramming
    Nim supports powerful metaprogramming features such as macros and templates, which allow for more flexible and reusable code.
  • Memory Management
    Nim gives developers control over memory management while also providing an efficient garbage collector, effectively balancing manual and automatic memory management.
  • Cross-Platform Compatibility
    Nim can compile code for various platforms, including Windows, macOS, and Linux, as well as the web through JavaScript.
  • Interoperability
    Nim has excellent interoperability with C and C++ code, making it easier to incorporate existing libraries and gain performance benefits.

Possible disadvantages of Nim (programming language)

  • Smaller Community
    Compared to more established languages like Python or JavaScript, Nim has a smaller community, which can lead to fewer resources, libraries, and third-party support.
  • Ecosystem Maturity
    While Nim is growing, its ecosystem is not as mature as some other languages. This can mean fewer libraries, tools, and frameworks for various tasks.
  • Learning Curve
    Despite its expressive syntax, Nim has unique features and paradigms that can present a learning curve for new developers, especially those coming from more mainstream languages.
  • Less Corporate Backing
    Nim does not have as much corporate support or adoption compared to other languages like Go or Rust, which could influence its long-term viability and industry adoption.
  • Compiler Bugs
    As a relatively young language, Nim's compiler may still have some bugs or less polished features compared to more established languages.

Questions & Answers

As answered by people managing Nim (programming language) 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.

  • Zig: Build System Reworked
    That's actually a great argument for Nim[0]. Easy interop with C, native-speed performance, and a syntax very close to Python in both readability and how quickly you can get something working. Batteries included, automatic memory management without a conventional GC and metaprogramming - is a really cool combination. [0] - https://nim-lang.org/. - Source: Hacker News / about 2 months ago
  • Go-legacy-winxp: Compile Golang 1.24 code for Windows XP
    Coincidentally, just a few days ago, I tried to run Nim[0] on Windows XP as an experiment. And to my surprise, the latest 32-bit release of Nim simply works out the box. But Nim compiles to C, so I also needed C compiler and all modern versions of mingw failed to launch. After some time I managed to find very old Mingw (gcc 4.7.1) that have finally worked [0].

  • Go Away Python
    You can replace Python with Nim. It checks literally all your marks (expressive, fast, compiled, strong-typing). It's as concise as Python, and IMO, Nim syntax is even more flexible. https://nim-lang.org. - Source: Hacker News / 7 months ago
  • Go Away Python
    Have you tried Nim? Strong and static typed, versatile, compiles down to native code vรญa C, interops with C trivially, has macros and stuff to twist your brain if you're into that, and is trivially easy to get into. https://nim-lang.org. - Source: Hacker News / 7 months ago
