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.
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.

Servo [0] is EU funded via NLnet. You can build a browser from that. [0] https://servo.org/. - Source: Hacker News / about 2 months ago
For those unfamiliar, Servo is a web rendering engine originally started at Mozilla Research. It's written in Rust from the ground up and was designed to take advantage of modern hardware through parallelism โ layout, styling, and painting can happen concurrently across CPU cores. Many of Servo's innovations actually made their way into Firefox over the years (Stylo, WebRender). - Source: dev.to / 4 months ago
Firefox was special in that Mozilla created Rust to build Servo and then backported parts of Servo to Firefox and ultimately stopped building Servo. Thankfully Servo has picked up speed again and if one wants a Rust based browser engine what better choice than the one the language was built to enable? https://servo.org/. - Source: Hacker News / 5 months ago
So things like media players from the native platform wouldn't be required. in-app browsers can use something like [servo](https://servo.org/) map-gis widgets can use something like [galileo](https://github.com/galileo-map/galileo). - Source: Hacker News / 8 months ago
I very much dislike that they arent available for linux. Which means I havent tested them; I also dont see a need for them. I dont want or use AI in the browser. Brave has had Leo for ages now. Qwen3 14b in the cloud is a fine model, no thanks though. I very much prefer my local llama private models for privacy. None of these ai browsers let you go local; but even if they did, I doubt id use it anyway. What the... - Source: Hacker News / 9 months ago
