RepDB is a one-time-purchase exercise dataset with animations for developers building fitness and workout apps — 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 600+ exercises with flat-style 512×512 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 — 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.

DeveloperToolsKit's answer
DeveloperToolsKit combines 35+ frequently used developer tools into a clean, fast, and modern interface—entirely in your browser, with no tracking, no registration, and no fluff. It's built with a privacy-first mindset and designed for speed and simplicity.
RepDB's answer:
RepDB is sold as a one-time download, not a metered API — 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.
DeveloperToolsKit's answer
Unlike many cluttered or ad-heavy alternatives, DeveloperToolsKit offers a seamless, ad-free experience with blazing fast performance. All tools are 100% free, mobile-friendly, and require no sign-up. It respects your privacy and saves you time.
RepDB's answer:
Most alternatives are subscription APIs — 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.
DeveloperToolsKit's answer
Our primary audience includes frontend and backend developers, DevOps engineers, software testers, and coding students who need reliable tools for data formatting, encoding, hashing, and more—accessible anytime, from anywhere.
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.
DeveloperToolsKit's answer
DeveloperToolsKit was created out of a developer's frustration with having to jump between dozens of different websites for simple, repetitive tasks. The goal was clear: bring the most essential tools together in one lightweight, private, and intuitive toolkit.
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.
