Shells.com offers a virtual cloud computer that can be accessed from any web-enabled device. As we offer multiple Linux distributions or Windows preloaded on the virtual desktop, it gives the user the opportunity to use the operating system that they want on the device that they want. This is great for new users who would like to give Linux a test run without having to install on their hardware or for developers who would like to test and deploy all on one device. Schools and businesses can rapidly deploy computers and phones to those who need them at a low-cost.

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.

Shells features and specs

  • Cross-device compatibility
    Shells allows users to access their virtual desktop environment from any device with an internet connection, whether it's a laptop, tablet, or smartphone. This flexibility enables seamless work and play across different devices.
  • Ease of setup
    Shells offers a straightforward and user-friendly setup process, making it accessible even for those with limited technical knowledge. Users can quickly get their virtual desktop up and running without the need for complex configurations.
  • Versatility
    Shells provides users with the ability to run multiple operating systems, including Linux and Windows, which adds flexibility for a variety of tasks and software requirements.
  • Cloud storage integration
    Shells offers cloud storage options, allowing users to easily store, access, and manage their files within their virtual desktop environment. This ensures data safety and convenience.
  • Scalability
    Users can easily scale their resources based on their needs, such as upgrading RAM or storage capacity. This ensures that Shells can grow alongside the user's demands.

Possible disadvantages of Shells

  • Dependent on internet connection
    Shells requires a stable and fast internet connection for optimal performance. Users with inconsistent or slow internet may experience lag or connectivity issues.
  • Recurring costs
    Using Shells involves a subscription-based payment model, meaning users must pay recurring fees to maintain access. This could be a con for users seeking a one-time purchase model.
  • Limited offline access
    Because Shells is cloud-based, users have limited functionality when they are offline, which could be disadvantageous for those needing constant access to their virtual desktops.
  • Potential security concerns
    Although Shells implements security measures, storing data in the cloud may still pose security risks, such as data breaches or unauthorized access, which may concern privacy-focused users.
  • Performance constraints
    Depending on the chosen plan and resource allocation, there may be performance limitations, particularly for users running resource-intensive applications compared to high-performance local machines.

Questions & Answers

As answered by people managing Shells 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.
