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.

Runno features and specs

  • In-browser execution
    Runno supports code execution directly in the browser, allowing users to test and run code without installing additional software.
  • Multiple language support
    The platform supports a variety of programming languages, making it versatile for developers working in different environments.
  • User-friendly interface
    Runno provides an intuitive and clean interface that is easy for both beginners and experienced users to navigate.
  • No server dependency
    Since the code runs entirely in the browser, there is no need for server-side processing, enabling a faster and more secure execution environment.
  • Open source
    Runno is open source, allowing developers to contribute to its development and customize it according to their needs.

Possible disadvantages of Runno

  • Limited computational resources
    Running code in the browser can be limited by the available computational resources and memory of the user's device.
  • Security concerns
    Executing code in the browser can pose security risks if not properly sandboxed, potentially exposing the system to vulnerabilities.
  • Dependence on browser capabilities
    The performance and range of features can vary depending on the capabilities and support of the user's browser.
  • Potential performance issues
    For complex and resource-intensive programs, in-browser execution might not match the performance of native or server-based environments.
  • Lack of full development environment features
    While it provides an excellent platform for trying out code snippets, Runno may lack some of the comprehensive tools available in full-fledged IDEs.

Questions & Answers

As answered by people managing Runno 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.

  • Ask HN: What Are You Working On? (March 2025)
    Working on Runno (https://runno.dev/) as a side project. It's a tool for running code in the browser for educational use. I've been playing around with turning it into a sandbox for running code in Python (https://runno.dev/articles/sandbox-python/). This would allow you to safely execute AI generated code. Generally thinking about more ways to run code in sandbox environments, as I think this will become more... - Source: Hacker News / over 1 year ago
  • Container2wasm: Convert Containers to WASM Blobs
    Really impressed by the depth and breadth of this project, well done! A particularly interesting part is the socket layer inside the browser. Other people solving this problem have previously used a proxy to a server that does the real socket implementation. This means you can't have a "browser-only" solution. The author has solved this (for HTTP/S only) by proxying HTTP requests and then re-creating them as fetch... - Source: Hacker News / over 2 years ago
  • Container2wasm: Convert Containers to WASM Blobs
    This is the use case I've been tackling with Runno (https://runno.dev), it's more performant than OP's approach but not as flexible. - Source: Hacker News / over 2 years ago
  • Interactive Code Cells
    I love these kinds of interactive code/sandbox projects! The author's example page [1] gives some more background on the design of Codapi as well [2]. Another similar project is Runno which runs entirely client-side in the browser [3].

  • Extism Makes WebAssembly Easy
    I'm working on this problem as well and would be happy to sling you some thoughts and notes. Check my website https://runno.dev and send an email to the address on that website! - Source: Hacker News / almost 3 years ago
