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.

Questions & Answers

As answered by people managing Lightspark 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.

  • When SVG almost got network support for raw sockets
    Not the first attempted Flash reimplementation[1,2,3]. The GNU one didnโ€™t work all that well back in the day as far as I remember, but then Flash was a moving target at the time.

  • Good flash emulator for walfas?
    A true emulator would be something like Ruffle or Lightspark. Ruffle I know doesn't work well with Walfas last time I checked. I don't know about Lightspark. Source: almost 4 years ago
  • Flash game to Html5 converter
    Lightspark, a browser plugin written in C++. It's a work in progress, not every flash content will work. Modern mainstream browsers don't support running it within a page, so flash content needs to be run in a standalone lightspark app, or in some lesser known browsers. Source: about 4 years ago
  • How and where do I tell CMake where my C/CXX compiler is?
    I'm trying to install lightspark on my computer, and it hinges on launching a shell script that mainly executes a CMake command. When I try ./build.sh (the name of the shell script), I get a bunch of lines of errors. The first one I think is major is CMake Error at /usr/share/cmake-3.23/Modules/CMakeTestCCompiler.cmake:69 (message): The C compiler "/usr/bin/cc" is not able to compile a simple test...

  • What "legacy" software are you still forced to use in 2022 that you wish would die?
    I'm having alot of fun with this post actually. I wouldn't be surprised if there was some alternative or workaround for whatever you guys need to run. For example, instead of the clunky Java, we have this. Instead of Flash, try this. Source: over 4 years ago
