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.

ReqRes features and specs

  • Free and Open Access
    ReqRes is freely accessible, providing developers with a simple way to test APIs without any cost barriers.
  • Comprehensive API Endpoints
    It offers a variety of endpoints for testing HTTP methods like GET, POST, PUT, DELETE, which are commonly used in RESTful APIs.
  • No Authentication Required
    Users can test API calls without needing to go through authentication processes, simplifying testing for quick development cycles.
  • Static Data
    Provides consistent and predictable data for users, enabling reliable testing conditions.
  • Educational Resource
    Serves as a tool for teaching and learning API integration and HTTP methods, useful for beginners.

Possible disadvantages of ReqRes

  • Limited Data Interaction
    ReqRes only uses static data, which might not completely mimic the dynamic nature of real-world APIs.
  • No Custom Data
    You cannot add or modify the dataset; it's predefined, which limits the scope for more extensive testing scenarios.
  • Lack of Authentication Testing
    Due to its simplicity and lack of an authentication mechanism, it's not suitable for testing scenarios that involve user authentication/security.
  • Limited to REST
    ReqRes only supports REST APIs, excluding developers who need to work with SOAP or GraphQL.
  • Not Suitable for Production
    Being a mock API, it's only suitable for development and testing, not for production environments.

Questions & Answers

As answered by people managing ReqRes 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.
