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 250 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.
Mux 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.

How are you storing/serving the videos? You might look at a service like mux.com which both hosts files behind a CDN but optimizes video delivery with adaptive bitrate streaming. If you are serving whole/raw video files off Cloudfront that could impact your costs. Source: about 3 years ago
Vimeo is a solid platform. Most alternatives you'll find searching for "vimeo vs." are just marketing / billing wrappers around the mux.com streaming platform. If you are somewhat technically inclined you can use mux.com directly and embed it on your website yourself. Source: over 3 years ago
Feels like there's no real alternative to Youtube since they have large enough capital to run the site to be barely able to break even. Feels like something like https://mux.com would meet the purpose jut feels like free streaming is way too costly. Source: over 3 years ago
The repo is unmaintained, ever since Matt moved from Twitch to mux.com, so the library does need a maintainer. There are some bugs and PRs that could do with merging to head, but it is generally functional, with some quirks. The code is used in both OBS and Gstreamer Rust bindings. Source: over 3 years ago
So Senja uses Mux under the hood for video storage and streaming. It's an amazing solution! Source: almost 4 years ago
