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.

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.
We were looking for a way to accept crypto payments with no changes to the rest of our workflow. After reviewing payment gateways, 0xProcessing was deemed more feasible than others. The setup was simple and once it ran, never required day-to-day attention. The ability to create payment requests is hassle-free and clear for daily transaction uses; hence, there is no confusion.
Following numerous payment drops and unexpected compliance holds with BitPay, we switched our primary checkout flow to 0xProcessing. Our global clients rely on cross-border technology, services, and products. We needed a payment gateway that is used to handling payment processing and wonโt raise flags about something this usual. Actually the onboarding as merchant was quite easy. The API integration into Vettrackโs custom billing stack has taken the dev team the best part of about two afternoons and the docs donโt leave much to the imagination.
To run its day-to-day operations, Stable is used. We rely heavily on this payment links feature, which is completely automated. The VRCS feature converts incoming volatile assets to stablecoins automatically. The latter aspect alone has given adequate protection to our margins during the dips which get tied up in the afternoon. The 18 supported networks includes nearly everything our clients use. The processing time in so minimal, and we have still yet to have our first chargeback or false fraud flag since we started using it. The interface is effective but has glitches.
Since we don't usually process such payments, we werenโt looking for one that was equipped with many sophisticated tools. The first things were reliability and setup that shouldnโt be hard to get used to.
After looking at a number of options Fireblocks included we found 0xProcessing easier to work with. The on-boarding process was simple and the documentation covered the majority of our needs. It has been doing its job with no additional work since implementation.
