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.

Possible disadvantages of GitBook

  • Pricing
    While GitBook offers a free tier, advanced features and larger projects may require a subscription, which might be expensive for smaller teams or individual developers.
  • Limited Customization
    Compared to some other documentation tools, GitBook may offer limited customization options beyond pre-defined themes, which might not meet the needs of some users for highly customized documentation.
  • Dependency on Platform
    Users are dependent on GitBook's platform and its availability, meaning any downtime or service issues on GitBook's end can affect access to and editing of documentation.
  • Learning Curve
    Despite being user-friendly, some users might still face a learning curve, especially those who are not familiar with version control or Markdown.
  • Export Options
    Exporting documentation in different formats like PDF, EPUB, or HTML may be limited or require additional steps, which can be inconvenient for users who need these features.
  • Feature Set
    Some users may find that GitBook lacks certain advanced features or integrations that other specialized documentation tools offer, potentially limiting its utility for highly technical documentation needs.

Questions & Answers

As answered by people managing GitBook 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.

  • The Ultimate Technical Writing Stack for 2025
    GitBook is simple and clean, and sometimes thatโ€™s exactly what you need. I like it for early-stage products or teams with lighter documentation. Youโ€™ll eventually hit limits if your structure gets more complex, but if simplicity is your priority, itโ€™s a solid choice. - Source: dev.to / 8 months ago

  • Show HN: We built a FOSS documentation CMS with a pretty GUI
    Good question that led to insightful responses. I would like to bring GitBook (https://gitbook.com) too to the comparison notes (no affiliation). They, too, focus on the collaborative, 'similar-to-git-workflow', and versioned approach towards documentation. Happy to see variety in the 'docs' tools area, and really appreciate it being FOSS. Looking forward to trying out Kalmia on some project soon. - Source: Hacker News / almost 2 years ago
  • GitLanding: A beautiful landing page for your Github project in a matter of minutes.
    You can have both a landing page (e.g.: www.your-project.dev) and a documentation website (e.g.: docs.your-project.dev). For creating documentation website GitBook is better fit than Gitlanding. GitBook is free for open source Projects (you just need to issue a request). - Source: dev.to / over 4 years ago
