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.
BlinkDisk
RepDBBlinkDisk's answer
BlinkDisk stands out by bridging the gap between power and simplicity. While it leverages the robust, battle-tested Kopia engine under the hood for military-grade deduplication and encryption, it wraps this complexity in a minimalistic, modern interface that requires zero technical knowledge
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.
BlinkDisk's answer
For Simplicity: Unlike technical tools like the Kopia CLI or Restic, BlinkDisk offers a true "set it and forget it" experience without sacrificing security. No command lines, no complex configuration filesโjust modern, intuitive software.
For Freedom: Compared to proprietary services like Backblaze or Carbonite, BlinkDisk is open source and supports the "bring your own storage" model. You're not locked into a specific vendor's infrastructure, and you can switch from the free self-hosted tier to the affordable CloudBlink tier (or back) as your needs change.
For Trust: With end-to-end encryption, your data is encrypted before it leaves your device. Combined with cross-platform support (Windows, Mac, and Linux), you get consistent, secure backups everywhere without compromising privacy.
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.
BlinkDisk's answer
Kopia: The foundational open-source library handling the heavy lifting. Content-addressable storage, client-side deduplication, and end-to-end encryption.
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:
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.
Based on our record, BlinkDisk seems to be more popular. It has been mentiond 1 time since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Backblaze's B2 storage is fine if used with a separate app over which you have more control. Others here have mentioned Arq. I have used it, as well as Kopia[0] and Blinkdisk[1] (Blinkdisk is essentially Kopia but with a nicer UI). Can recommend all three highly; the latter two are FOSS.
