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 250 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.

Live HTTP Headers features and specs

  • Real-time Monitoring
    Live HTTP Headers allows users to monitor HTTP traffic in real-time, which helps in debugging and understanding how webpages interact with the server.
  • Detailed Header Analysis
    The tool provides comprehensive details of HTTP headers, making it easier to analyze and troubleshoot specific issues with HTTP requests and responses.
  • Browser Integration
    Live HTTP Headers integrates directly with web browsers like Firefox, providing a convenient way to access header information without needing external tools.
  • User-Friendly Interface
    The extension provides a straightforward and easy-to-use interface that can be navigated by users with varying levels of technical expertise.

Possible disadvantages of Live HTTP Headers

  • Limited to Specific Browsers
    As an extension primarily for Firefox, Live HTTP Headers may not be as versatile for users of other browsers without similar support.
  • Outdated Components
    The development and updates for Live HTTP Headers have been limited, which may lead to compatibility issues with newer browser versions or standards.
  • Less Feature-Rich Compared to Alternatives
    Newer tools and extensions, such as the Chrome DevTools, provide more advanced features beyond basic HTTP header inspection.
  • Security Concerns
    Since the extension has access to HTTP traffic, there's a potential, albeit low, risk that it could be exploited or become vulnerable if not properly maintained.

Questions & Answers

As answered by people managing Live 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.
