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.

CoreOS Clair features and specs

  • Security Focused
    Clair is designed to identify vulnerabilities in Docker and appc container images, which helps in maintaining a secure container environment.
  • Open Source
    As an open-source project, Clair allows users to review the code, contribute improvements, and avoid vendor lock-in.
  • Rapid Vulnerability Updates
    Clair frequently pulls from well-known vulnerability databases, ensuring updated information is used to scan for exploits.
  • Integration Friendly
    Clair provides an API that makes it easy to integrate with CI/CD pipelines and other DevOps tools to automate vulnerability scanning.
  • Scalable
    Designed to handle large-scale vulnerability scanning and can be deployed in clustered environments to scale as needed.

Possible disadvantages of CoreOS Clair

  • Complex Setup
    Setting up Clair requires a good understanding of Docker, databases, and sometimes additional configuration, which can be challenging for beginners.
  • Performance Overheads
    Running frequent scans can introduce performance bottlenecks, especially in resource-constrained environments.
  • Limited Language Support
    Clair primarily focuses on vulnerabilities in C/C++ and package managers, which may not cover all the software languages used in container images.
  • False Positives
    Similar to many vulnerability scanners, Clair can occasionally report false positives, which require manual verification and can take up time.
  • Dependency on External Sources
    Clair’s effectiveness relies heavily on the accuracy and availability of external vulnerability databases and sources, which can be a point of failure.

Questions & Answers

As answered by people managing CoreOS Clair 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.
