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 400 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 CDemu

  • Linux Exclusive
    CDemu is specifically designed for Linux systems, which means it is not available for Windows or macOS users, limiting its user base.
  • User Complexity
    While offering powerful features, CDemu can have a steep learning curve for users unfamiliar with mounting virtual drives or using command-line tools, which might not be intuitive for beginners.
  • Limited Support
    Being a community-driven project, CDemu might not provide the same level of professional support as commercial tools. Users might need to rely on community forums and documentation for help.
  • Development Activity
    Open-source projects like CDemu may experience periods of slow development activity, which could delay new features or bug fixes compared to commercial software with dedicated development teams.

Questions & Answers

As answered by people managing CDemu 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.

CDemu mentions (4)

  • There are now more Linux gamers than Windows 7 gamers
    Have a look at https://cdemu.sourceforge.io/. Comes with a virtual drive kernel module, an image parser library supporting most formats (including old MDX, newer rips won't work because of encrypted file headers, so stay away from Daemon Tools images), and a configuration GUI sitting in the system tray. Source: about 3 years ago
  • I am trying to run an old CD-based game from 2001 using Wine.
    Also mounting the resulting image won't work without another specific program that emulates that copy protection. CDEmu might work but there's no guarantee. Source: over 3 years ago
  • How do I install CDEMU?
    I'm quite new to this. https://cdemu.sourceforge.io/. Source: over 3 years ago
  • How to get a backup of an old game CD with copy protection?
    I used Daemon Tools (the Windows software) to rip my game disks to MDS/MDF images. As far as I remember, the free “light”/adware version is sufficient. On Linux, you can mount the resulting images via cdemu. Source: over 3 years ago
