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.
FastMinify is a modern collection of free online developer tools designed to simplify code optimization and data transformation workflows. The platform includes utilities for minifying, beautifying, encoding and decoding formats such as JavaScript, CSS, HTML, JSON, XML, SVG, Base64 and URLs โ all without registration or unnecessary complexity.

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.
FastMinify's answer:
FastMinify focuses on simplicity, speed and privacy. All tools work instantly in the browser without registration, unnecessary UI complexity or intrusive popups. The platform combines code minification, beautification and encoding utilities in a single lightweight developer-focused experience.
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.
FastMinify's answer:
FastMinify provides a fast and distraction-free experience with modern tooling, clean output formatting and support for multiple formats in one place. It is designed for developers who want quick utilities without accounts, bloated interfaces or workflow interruptions.
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.
FastMinify's answer:
FastMinify is built for web developers, frontend developers, backend developers, DevOps engineers, students and anyone who regularly works with code, APIs or web data formats.
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.
FastMinify's answer:
FastMinify was created to provide developers with a cleaner and faster alternative to outdated online code tools. The goal was to build a modern platform focused on essential developer utilities with a strong emphasis on usability, performance and simplicity.
FastMinify's answer:
FastMinify is currently used by independent developers, freelancers, students and small development teams.
