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.
Emby
RepDBEmby is recommended for users who want full control over their media server and prefer a solution that allows for easy streaming across different devices. It's ideal for tech-savvy individuals who are comfortable setting up and maintaining a home media server. Additionally, it's great for families or groups who want to share media content and have comprehensive access control features. Those who are looking for a media server with a strong emphasis on privacy might also find Emby to be a suitable choice.
RepDB'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.

Have you heard of Emby? It seems to be closed-source. However you can still run it yourself [0]. UX appears to be better than Jellyfin, but I haven't tried either and not sure which one to go for. [0] https://emby.media. - Source: Hacker News / 6 months ago
I used to use Plex until I found Emby. I find Emby easier to use and it does the same thing. Just putting this here as a fourth option for OP. :). Source: over 2 years ago
I use https://emby.media along with private trackers and Usenet. - Source: Hacker News / about 3 years ago
You can find it here! I have both installed, but I generally keep EMBY turned off until I want to play around with it. You can have both running at once and both accessing the same folders. You can check it out for free. Source: about 3 years ago
