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.
Overtone 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.

When I last played with SuperCollider I used Overtone, that wraps everything in a Closure API. With that you use s-expressions instead of sclang to define your sounds. I am not sure what the state of Overtone is these days, but there seems to still be some activity: https://overtone.github.io/. - Source: Hacker News / 10 months ago
> Midi being an โartistโ tool places it more as a medium like paint. Iโve used MIDI โas paintโ. Written music using code to MIDI(1), and wrote โcross instrumentโ music, ie using my keyboard as drum machine. But these days MIDI is chiefly an archival method for me. Every time I touch my keyboard is recorded, is much smaller than a comparable audio recording, by design โforced fidelityโ in the recording, and I am... - Source: Hacker News / over 2 years ago
You might want to look at Overtone, which is a clojure environment built on top of overtone, and which integrates with processing and a few other similar things. https://overtone.github.io/. - Source: Hacker News / over 3 years ago
> I'm fluent in Python but find the use of colons is the real sticking point. The you'd probably have hated its predecessor which was all about the parentheses: https://overtone.github.io/ It's too bad that superficial stuff like which characters you need to type is holding you back. Getting used to Ruby when you're familiar with Python is no big deal. I would just stick with it. - Source: Hacker News / over 3 years ago
There's a project you may find interesting: https://overtone.github.io/. Besides sound/synthesis stuff, it has https://github.com/overtone/midi-clj library, which allows you to write MIDI as lisp (Clojure, to be precise) code. Emacs has great support for Clojure programming (via Cider), and REPL-based development is perfect for writing music. Source: almost 4 years ago
