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.

HTTP Headers features and specs

  • Flexibility
    HTTP headers allow for a flexible mechanism to send metadata along with HTTP requests and responses, making it easier to implement features like content negotiation.
  • Control
    They provide fine-grained control over HTTP transactions, allowing developers to specify caching policies, authentication, and content types.
  • Standardization
    HTTP headers follow well-defined standards, making it easier to ensure interoperability across different systems and applications.
  • Security Features
    Headers like Content-Security-Policy and Strict-Transport-Security enhance the security of web applications by protecting them against various attacks.
  • Performance Optimization
    Headers related to caching (e.g., Cache-Control) and compression (e.g., Accept-Encoding) help optimize the performance of web applications by reducing load times.

Possible disadvantages of HTTP Headers

  • Complexity
    The large number of available HTTP headers can lead to increased complexity in application logic, making it harder to manage effectively.
  • Security Risks
    Improper use of headers can introduce security vulnerabilities, such as exposure of sensitive data through unnecessarily verbose headers.
  • Lack of Enforced Standards
    While headers are standardized, there is no strict enforcement, leading to potential discrepancies in implementation and support across different browsers and servers.
  • Overhead
    Excessive use of headers can increase the size of HTTP requests and responses, which may negatively impact performance, especially on limited bandwidth connections.
  • Misconfiguration
    Incorrectly configured headers can lead to issues such as caching errors or improper content delivery, which can degrade the user experience.

Questions & Answers

As answered by people managing HTTP Headers 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.
