RepDB
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 512ร512 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.
coderpad RepDBRepDB'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.
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.
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.
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.

Some companies use things like CoderPad or Google Docs (yes, Google really used to use Google Docs). Those don't let you run the code either so they're more like whiteboards. Source: over 3 years ago
I am a CS major with a computer engineering minor. I want to prepare myself to apply for an Embedded Engineering Internship. The interview process includes a coding task on coderpad.io, I have no clue what to expect - what kind of questions will be asked for an embedded internship? I say this because coding embedded systems is rather different from "regular" coding in practice. High level v low level. Source: over 3 years ago
CoderPad : Quickly Conduct Coding Interviews and Phone Screen Interviews. - Source: dev.to / over 3 years ago
I am prepping for a final round interview for a frontend position at a medium size company. The recruiter gave me some information about one of the coding rounds and I am not entirely sure what to expect. The description says I will be building a fullstack web app, and the goal is to test my frontend and backend knowledge, and get a working solution. I will be using https://excalidraw.com/ in addition to... Source: over 3 years ago
The specific target interview format I have in mind is via a shared, live editor (e.g. https://coderpad.io/) and a video link, lasting ~1hr. The practice format might be more like 45min for the interview followed by 15 - 30min for feedback and discussion. Doing two of those back to back so both of us get our chance in the hot seat could be exhausting, so this might be two separate sessions. Source: over 3 years ago
