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.

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.

For those actively teachingยน, consider Snap! (https://snap.berkeley.edu/) over/after Scratch. It's nearly a superset, similarly "low-floor" but much "higher ceiling" powerful language. Data structures, control structures/message passing, functional programming... It's really "Scheme in Scratch clothing" under the hood. In particular, its "build your own blocks" facilities are powerful enough (including macros... - Source: Hacker News / 9 months ago
Snap! https://snap.berkeley.edu/ Also, I heartily recommend the demoes that the author is giving regularly at FOSDEM. They're really fun to watch :). - Source: Hacker News / about 1 year ago
Kids would probably have a better experience with Hedy https://hedy.org if they are young, and Pyret https://dcic-world.org if they are a little older. Once they know how to program python is obviously a fine choice, but starting beginners with Python is insane. Too many gotchas, incomprehensible error messages etc. Also why logo? Its not 1967 anymore. A far better choice is Snap! https://snap.berkeley.edu. - Source: Hacker News / over 1 year ago
I upgraded my son from Scratch to Snap! (https://snap.berkeley.edu/). Snap has a much higher ceiling, including collections, first-class code pieces, higher-order functions etc. It pretty openly describes itself as a "Scheme disguised as Scratch" :-) A pragmatic pedagogical thing I love with Snap! Is the ease of creating custom blocks, including macros / custom "C-shaped" control structures. If you have some... - Source: Hacker News / almost 2 years ago
Take a look at Snap. It was originally a scratch mod, but does allows for all sorts of advanced things. https://snap.berkeley.edu. - Source: Hacker News / about 2 years ago
