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.

Gnirts features and specs

  • String Obfuscation
    Gnirts provides a simple way to obfuscate strings, which can help protect sensitive information in your code base by making it less readable to humans.
  • Ease of Use
    The package is user-friendly and straightforward to implement, allowing developers to quickly integrate string obfuscation into their projects without significant adjustments or learning curve.
  • Lightweight
    Gnirts is a lightweight package that does not add significant overhead to your project, making it suitable for use in a wide range of JavaScript and Node.js applications.

Possible disadvantages of Gnirts

  • Limited Security
    While Gnirts obfuscates strings, it does not provide robust security. Experienced developers or attackers can potentially reverse-engineer the obfuscation, so it should not be relied on for protecting critical data.
  • Specific Use Case
    Gnirts is specifically designed for string obfuscation and may not fit projects or developers looking for broader obfuscation features or additional security measures for other types of data.
  • Maintenance and Updates
    As with any third-party package, there's potential risk related to the package's maintenance and future updates. If not actively maintained, it may cause compatibility issues with new JavaScript or Node.js versions.

Questions & Answers

As answered by people managing Gnirts 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.
