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.

Cubic features and specs

  • User-Friendly Interface
    Cubic provides a straightforward and intuitive interface, making it accessible even for users with limited experience in creating or customizing Linux ISOs.
  • Customizability
    Cubic allows users to easily customize Ubuntu-based distributions by installing software, tweaking settings, and adding files directly into the ISO image.

    The application provides a real-time preview of the ISO being customized, helping users to visualize the final product and make adjustments as necessary.
  • Enhanced Control Over Packages
    Cubic facilitates easy manipulation of package lists, including the ability to add, remove, or enable specific repositories for package installation.

Possible disadvantages of Cubic

  • Limited to Ubuntu-based Distributions
    Cubic is specifically designed for customizing Ubuntu and its derivatives, meaning it is not suitable for other Linux distributions.
  • Requires Linux Knowledge
    Despite its user-friendly interface, Cubic still requires a basic understanding of Linux commands and environment to make effective customizations.
  • Dependency on Ubuntu Packages
    Customizations are reliant on packages available within Ubuntuโ€™s repositories, which may limit the scope of modifications for users who require non-Ubuntu packages.
  • Performance and Resource Limitations
    Running Cubic can be resource-intensive, requiring significant CPU and memory usage, especially during intensive operations like large package installs or complex customization scripts.

Questions & Answers

As answered by people managing Cubic 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.
