RepDB
RepDB is a one-time-purchase exercise dataset with animations for developers building fitness and workout apps — 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 600+ exercises with flat-style 512×512 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 — 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.

RepDB's answer:
RepDB is sold as a one-time download, not a metered API — 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 — 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.

Yew is one of the most popular Rust frameworks (it currently has 30.5k stars on GitHub) for building modern web applications. - Source: dev.to / over 1 year ago
Compare this to Yew, a Rust framework that does this correctly. Yew's Link component only accepts values from a Routable enum. This enforces compile-time guarantees that a route is valid and internal. You cannot accidentally pass in a user-controlled string and redirect them to a malicious site. That's type safety. That's Rust's promise. And that's what Dioxus breaks. - Source: dev.to / over 1 year ago
Rust? It's built clean from the ground up. The crates.io registry is full of modern, safe, composable libraries. You've got Axum, Rocket and Actix for backends, Leptos, Dioxus, and Yew for frontend, and more. Every library you use follows the same philosophy: safety, performance, and zero tolerance for ambiguity. - Source: dev.to / over 1 year ago
> To my knowledge there is not a Vue/React-WASM-type framework out there yet or any framework for building web apps in WASM (without starting from a blank canvas). Not sure if these qualify, but these Rust web frameworks use wasm: https://dioxuslabs.com/ https://yew.rs/. - Source: Hacker News / over 1 year ago
Leptos, Yew and Dioxus are modern frameworks for building front-end web apps in Rust. These all compile to Wasm. - Source: dev.to / over 1 year ago
