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.

Hanami features and specs

  • Lightweight and Fast
    Hanami is designed to be lightweight and efficient, providing faster performance compared to larger frameworks like Rails. This is achieved through streamlined code and modular architecture.
  • Modular Architecture
    Hanami embraces a modular structure that encourages clear separation of concerns. This makes it easy to manage and scale applications by isolating each componentโ€™s functionality.
  • Less Magic
    The framework uses explicit conventions over implicit 'magic,' which means developers have clear visibility over what their code is doing, leading to a better understanding and easier debugging.
  • Concurrency
    Hanami is designed to be thread-safe, allowing applications to handle concurrent requests more effectively, leveraging Ruby's concurrency model.
  • Test-Driven Philosophy
    Hanami promotes a strong culture of testing, providing built-in support for writing tests, which encourages good practices and helps maintain code quality.

Possible disadvantages of Hanami

  • Smaller Community
    Compared to frameworks like Rails, Hanami has a smaller community. This can mean fewer resources, tutorials, and third-party libraries available for developers.
  • Learning Curve
    Developers familiar with Rails or other full-stack frameworks may face a learning curve due to Hanamiโ€™s unique conventions and architecture.
  • Less Gem Support
    Some popular Ruby gems may not be fully compatible with Hanami, requiring extra effort to integrate or find alternative solutions.
  • Less Proven
    While powerful, Hanami isnโ€™t as battle-tested as older frameworks like Rails, which can be a concern for long-term maintenance and reliability.
  • Limited Documentation
    The documentation for Hanami, while available, may not be as comprehensive or detailed as that of more established frameworks, posing challenges for new adopters.

Questions & Answers

As answered by people managing Hanami 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.

Get Over Ruby on Rails โ€” 3 Alternative Web Frameworks Worth Checking Out
Hanami used to be called Lotus, but because of some copyright issues with IBM, it was renamed Hanami.

If you want to follow their progress, I recommend following Tim Riley and Piotr...

  • Mruby: Ruby for Embedded Systems
    Hanami remains a bright spark as an alternative growing Ruby app framework to Rails. The project is under active development, Iโ€™ve met the core dev and they are lovely and much more humble than DHH and the project aims to stick much closer to the Ruby ways of doing things as opposed to the rails way. Sure the project just canโ€™t be as mature as Rails but it deserves a look and we need to get behind projects like... - Source: Hacker News / 8 months ago
  • Should You Use Ruby on Rails or Hanami?
    While Rails is very well-known in the Ruby community, Hanami is less so. It's a fairly new modern Ruby framework trying to take on Rails' dominance of the full-stack web framework space. - Source: dev.to / over 2 years ago

  • Is Ruby a dying language?
    No, it's just no longer over-hyped. Ruby is settling into being a mature production language, similar to Python, Java, .NET, C++, etc. As you can see from the RedMonk 2023 data Ruby is very much still alive with tons of repositories on GitHub. Besides Shopify, GitHub is another big Ruby/Rails shop. Also, besides Rails, there are other new and upcoming projects like Hanami, DragonRuby, and Ronin. Source: over 2 years ago
  • Enhancing development with REPLs - A practical guide
    On all my application tutorials I start by setting up an application level REPL, it's basically a console script that loads all the files inside your project, if you're using a framework like Ruby on Rails or Hanami you already have a console by running the command console also. - Source: dev.to / almost 3 years ago
