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.

Possible disadvantages of HTML Comment Box

  • Limited Features
    Compared to more robust commenting systems, HTML Comment Box offers fewer features, which may not meet the needs of websites looking for advanced functionalities like rich text editing or social media integration.
  • Ads in Free Version
    The free version of HTML Comment Box displays ads, which could detract from the user experience and affect the aesthetic of the website.
  • No Account Management
    There is no account system for users, meaning commenters cannot edit or delete their comments after posting, which could be a disadvantage for user experience.
  • Potential for Spam
    The lack of an advanced spam filter can result in an increased volume of spam comments, requiring additional moderation efforts from website administrators.
  • Data Ownership
    As a third-party service, HTML Comment Box entails some loss of control over comment data, which is stored off-site, raising potential privacy and data sovereignty concerns.

Questions & Answers

As answered by people managing HTML Comment Box and RepDB.

What makes your product unique?

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.

What's the story behind your product?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

    Guestbooks work, but if you want it integrated into your site I suggest cbox or html comment box. Source: over 3 years ago
  • Building a custom online chat
    I have always wanted my own Instant Messager/Message Board. And I figure, with my new server I built, easy peasy right? Well no. Turns out I have 0 idea what I'm doing. I want anyone on the LAN to be able to pop a message to the whole board. It doesnt have to be great, just split bubbles of text and the ability to send messages, with a username if we really want to be fancy. No accounts or anything needed, like...

  • ive been thinking about adding a comment feature to my blog section, service recommendations?
    Https://htmlcommentbox.com/ has a good free plan. You can style it with css, it has a comment section per page, is moderateable, and lets you sign in to appear as a mod. Source: over 3 years ago
  • Is there a chat or commenting option I can put on a page that doesn't require another login?
    You can use embed pages from community softwares like Discourse or Flarum or you can use HTML Commentbox or you can just build your own commenting system (it's not that hard). Another option can be Commentbox but it requires external login but only allows third-party auth and has lots of options like Twitter, FB, Google, Github etc. Source: over 4 years ago
