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.
Poki
RepDBPoki is recommended for casual gamers, children, and anyone looking for free, easily accessible online games. It's suitable for people who enjoy playing short games during breaks or want to try out a variety of game genres without downloading or committing to a single title.
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.
Based on our record, Poki seems to be more popular. It has been mentiond 38 times 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.
The new approach this year is a pre-survey ask for help updating the questions, which the community answered. We had multiple Pull Requests on GitHub with valuable additions, which we then rewarded. It all wouldnโt be possible without this yearโs partner: we had support from Grant for the Web in 2021, OP Games in 2022, and 2023 was saved by Poki, for which weโre incredibly grateful. - Source: dev.to / over 2 years ago
I personally use three three websites when I wanna goof around for a bit, but there are tons of other sites like it. Https://www.mmobomb.com/browsergames Https://poki.com/ Https://www.crazygames.com/. Source: over 2 years ago

But if you're doing a larger project, especially if others will be writing the sub-apps (think of something like poki.com where 3rd-party content is hosted) then you probably want a separation, not at the code level, but at the build/runtime level. You see, even with code separation the sub-apps share session/local storage and so can mess with one another. The standard approach here is iframes. Have your player... Source: about 3 years ago
I turned into webgames recently. A publisher like poki.com has ads but few and it's a pleasure to play there now. Source: about 3 years ago
