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.

AppImageKit features and specs

  • Portability
    AppImage packages can run on most Linux distributions without needing to be installed, ensuring compatibility across various systems.
  • Simplicity
    AppImages do not require root permissions to execute, making it simple for end-users to run applications without administrative access.
  • No Installation Required
    Since AppImages are self-contained executables, users donโ€™t need to worry about installation processes, dependencies, or system changes.
  • Isolation
    Applications packaged as AppImages are isolated from the host system which minimizes conflicts with other installed software.
  • Version Control
    Users can have multiple versions of the same application by downloading different AppImage files, allowing easy testing and use of different releases.

Possible disadvantages of AppImageKit

  • Lack of Dependency Management
    Unlike traditional package managers, AppImage does not handle dependency resolution, which can lead to larger file sizes if all dependencies are bundled.
  • Limited Integration
    Out-of-the-box, AppImages may not integrate seamlessly with the host systemโ€™s desktop environment in terms of shortcuts and MIME types.
  • Security Concerns
    Because AppImages run with the same permissions as the user executing them, a malicious AppImage could potentially harm the user's system if not properly verified.
  • Updates
    Unlike some other packaging systems, AppImage does not inherently support automatic updates, requiring manual download of new versions.
  • Non-Native Look
    Applications might not look consistent with other native applications as AppImages bundle their dependencies which may not conform to the hostโ€™s theme and settings.

Questions & Answers

As answered by people managing AppImageKit 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.

  • Why Flatpak Apps Use So Much Disk Space on Linux
    The equivalent of "Windows portable apps" on Linux isn't flatpaks (these add a bunch of extra stuff and need some sort of support from the OS) but AppImages[0]. AppImages are still not 100% the same (and can never be as Windows applications can rely on A LOT more stuff to be there than Linux desktop apps) but functionally/UX-wise they're the closest: you download some program, chmod +x it and run it like... - Source: Hacker News / about 1 year ago

  • Show HN: Finic โ€“ open-source platform for building browser automations
    Like again if you are not sure, what open source means, this is open source: https://appimage.org/ Hope it is abundantly clear with this example. Docker tried it's best to do the whole open source but business first and it led to disastrous results. At best this will make your company suffer and second guess itself and at worst this is moral fraud. Talk to your group partner about this and explain to them as well. - Source: Hacker News / almost 2 years ago
  • GoboLinux
    What you're looking for sounds like AppImages (https://appimage.org/) . I have only used them while downloading games from itch.io, etc. (since I prefer package managers) but they seem to work out of the box on popular distros. - Source: Hacker News / over 2 years ago
