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.

Lerna features and specs

  • Monorepo Management
    Lerna excels at managing JavaScript projects with multiple packages in a single repository, streamlining development processes and reducing complexities associated with managing separate repositories.
  • Versioning and Publishing
    It offers powerful tools for versioning and publishing packages, automating the process of updating package versions and changelogs, which is particularly useful for maintaining multiple packages.
  • Dependency Management
    Lerna offers efficient handling of intra-repository dependencies by linking packages locally, which reduces redundant installations and improves build times.
  • Increased Collaboration
    By consolidating multiple projects into a single repository, Lerna enables better collaboration across teams, facilitating easier sharing and reuse of code.
  • Simplified Workflow
    Developers benefit from simplified workflows with consistent tooling and configurations, thus saving time and effort in package management.

Possible disadvantages of Lerna

  • Performance Overhead
    For very large projects, Lerna can introduce performance overhead, particularly in terms of bootstrapping, which may slow down development processes.
  • Complexity for Small Projects
    For smaller projects or those with fewer packages, Lerna can introduce unnecessary complexity, making it overkill for simple setups.
  • Steep Learning Curve
    New users or teams may face a steep learning curve due to Lernaโ€™s comprehensive set of features and configurations, requiring time to understand its workflows and conventions.
  • Tooling Integration
    Not all tools and CI/CD pipelines integrate seamlessly with Lerna, potentially requiring additional configuration or scripts to fully leverage its capabilities.
  • Limited Non-JS Support
    Lerna is primarily focused on JavaScript projects, which might limit its usefulness in polyglot environments or for teams working with multiple programming languages.

Questions & Answers

As answered by people managing Lerna 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.

  • Inside a 3-app Turborepo monorepo: parallelism, caching, and CI that stays fast
    But workspaces alone doesn't handle task orchestration โ€” what to build first, what to cache, what to skip. For that, build tools like Lerna, Nx, or Turborepo are generally used. They sit on top of workspaces, not in place of them โ€” you use both. - Source: dev.to / 3 months ago
  • Nx Monorepo Guide: React & Node Fullstack App
    Lerna was one of the first monorepo tools, focusing on managing and publishing packages. Nx goes much further by including a full build system and more. - Source: dev.to / about 1 year ago
  • EMPTY_OBJ in Inferno.Js source code.
    Coming back to render method, to locate this method in the codebase, Inferno codebase is a monorepo and is managed using lerna. You can confirm this by checking out lerna.json. - Source: dev.to / about 1 year ago

  • Monorepo Tutorial With Lerna, Storybook & Next.js
    In this tutorial, you'll learn how to build a monorepo using Lerna. Weโ€™ll be building a Next.js application which will import components from a separate package. Weโ€™ll also be using Storybook to showcase those components. - Source: dev.to / over 1 year ago
