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 512ร—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 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.

CAcert features and specs

  • Free Certification
    CAcert provides free digital certificates, making it an attractive option for individuals or organizations looking to secure their communications without incurring the costs associated with commercial certificate authorities.
  • Community-Driven
    As a community-run initiative, CAcert relies on its members for the verification process and policy development, fostering a collaborative environment that encourages participation and input from its user base.
  • Increased Learning Opportunities
    Engaging with the CAcert platform can offer users a deeper understanding of the processes involved in digital certification, from identity verification to certificate issuance and management.

Possible disadvantages of CAcert

  • Limited Browser Trust
    CAcert's root certificate is not included in the default trust stores of most major web browsers, which means users often need to manually install the certificate, reducing convenience and potentially trust.
  • Reliability Concerns
    Because CAcert is a volunteer-driven initiative, questions about long-term stability and support may arise, which can be a concern for individuals and organizations that require a reliable digital certification solution.
  • Less Professional Support
    Compared to commercial CAs, CAcert may offer less robust customer support and troubleshooting services, as it lacks the resources and infrastructure of larger, profit-driven entities.

Questions & Answers

As answered by people managing CAcert and RepDB.

What makes your product unique?

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.

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 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.

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.

  • Online validation of email address in GPG keys?
    Cacert.org provides this (http://wiki.cacert.org/PgpSigning). However, their service is not working at the moment - and regardless, would like to know if there are any other similar services that anyone is aware of. Source: almost 5 years ago
  • Code signing with a non-trusted certificate
    Now, I've written a couple little modules and released them. It's not really in my budget to purchase a paid signing certificate right now, though. However, I have an account in good standing at CAcert and could get a code signing certificate. Source: over 5 years ago
