RepDB is a one-time-purchase exercise dataset 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 250 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.
RepDBRepDB'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.
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 — 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.

Maybe giscus https://giscus.app/ It works for static sites, you just need to embed their script, and spam and moderation would be handled by GitHub. - Source: Hacker News / 3 months ago
Look the bottom of that page: An error occurred: API rate limit already exceeded for installation ID 73591946. Error from https://giscus.app/ Fellow says one thing and uses another. - Source: Hacker News / 7 months ago
I did the same. I was sad to lose the comments, but the ads were awful and I don't particularly want someone elses ads / tracking on my hobby site. I switched to gisqus [1], which is powered by GitHub discussions, which seems to be working ok. (The site is hosted on GH pages so seems reasonable to also use GH discussions for the comments.)

3) No commenting feature, luckily I found your post here on HN. But it would be better to have comment blocks, like from https://giscus.app/ or just a link where readers can comment. - Source: Hacker News / over 1 year ago
If you're a developer, you might start by using a static site generator and GitHub Pages. Stick to Markdown and start collecting and writing stuff. Sooner or later you'll get comments and regular readers. Then you might start to add editing or simply give other people access to GitHub. The editing experience of Markdown files in GitHub is not too bad and you get started in no time. From my experience it's more... - Source: Hacker News / over 1 year ago
