RepDB
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 512ร512 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.
IHP RepDBRepDB'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.
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.
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.
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.

Https://ihp.digitallyinduced.com/ is a rails-inspired framework for Haskell that tries to get the best of both worlds. Highly recommend trying it if you have a weekend. - Source: Hacker News / 5 months ago
> Does elixir have an lsp as good as Typescripts? Iโm a bit addicted to static types at the moment. I wonder how IHP [1], the liveview in Haskell, compares with Phoenix liveview for typical use cases now. (Not having used either.)

I found IHP straightforward: https://ihp.digitallyinduced.com/ despite not remembering much haskell! This assumes you can get past nix for the install. I find IHP well-designed. I just wish the licensing scheme were more transparent. - Source: Hacker News / almost 3 years ago
IHP is a batteries-included web framework similar to "ruby on rails" for Haskell, with strong static typing. The website has lots of information and videos and beginner tutorials. https://ihp.digitallyinduced.com/. - Source: Hacker News / almost 3 years ago

Scotty - Scotty is a Haskell framework inspired by Ruby's Sinatra.
wai-routes - Type safe routing framework for wai
Happstack Lite - Happstack itself is a web framework created in Haskell. Happstack Lite is an easier version to use that can import features from the heftier version if need be.
Apiary - Collaborative design, instant API mock, generated documentation, integrated code samples, debugging and automated testing
Yesod - Yesod is a development tool used to create highly efficient websites and web applications from the ground up. Yesod includes almost everything you need to build a website, from templates to routing and execution. Read more about Yesod.
Nested-Routes - Very similar to Scotty, except with the ability to nest handlers and embed parsers as a location to handle.
