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 250 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.
Playwright 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.

Browsers are automatable by design. Most agent tools ship their own browser or Drive an external one; point Playwright at a page and Every element has a stable, queryable handle. The DOM is an accessibility tree Wearing a different hat โ roles, labels, structure, all there for the reading. For The web, this half of debugging is close to solved. - Source: dev.to / 7 days ago
To see why this matters, it helps to remember what people are reaching for a different browser to do. Playwright is excellent at driving a browser, and scrapy-playwright wires that capability into Scrapy at the download handler so a rendered page arrives through the normal request and response cycle, asynchronously and quickly. The catch is the binary. The Chromium and Firefox builds that Playwright ships are the... - Source: dev.to / 22 days ago
Browser automation has been dominated by tools like Selenium and Playwright. They're very powerful, but you need to understand the DOM, manage selectors, and set up a testing stack before doing anything meaningful. - Source: dev.to / 27 days ago
There is no live demo, but you can have a look at the screenshots taken by playwright during testing. - Source: dev.to / about 1 month ago
We ran straight into this while building a course product on top of The AI Platform. I want to walk you through how we ended up testing the whole chat flow end to end with Playwright. - Source: dev.to / about 1 month ago
