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.
Privacy.com RepDBPrivacy.com is recommended for online shoppers, privacy-conscious individuals, and anyone looking to manage their financial transactions securely. It's especially useful for those who engage with multiple online subscriptions and purchases, providing an extra layer of protection against data breaches and credit card fraud.
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.
Real easy to use-- at first. As time went on it got harder and harder to get it to work. Finally it 'lost' my password, so I couldn't use it, and 'Support' never got back to me; but they did send me a 'customer satisfaction survey.' Hah!

I use https://privacy.com for this, you can create virtual cards with total spend limits. - Source: Hacker News / 10 months ago
I use a service called Privacy [1] to generate virtual card numbers, which I than use with all of my subscriptions. All of the virtual cards are tied to a physical credit card used as the funding source. I get a notification every time a card is charged or a charge is denied (if it's above the set limit or no longer active). This has saved me from fraud where a single-use virtual card # I used to pay for airport... - Source: Hacker News / over 2 years ago
