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.
Thymer 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.

We're building a multiplayer IDE [1] but for tasks/planning where docs needs to be trees/graphs (to support outlining, refs, transclusions and so on) We can't just merge any type of operation by replaying unconditionally, because that can cause tree cycles for example. Like the linked list certain operations can be valid locally for an offline client, but not globally in the converged order. Our sync engine... - Source: Hacker News / 7 days ago
We're building a new multiplayer IDE but for docs/tasks [1]. Local-first, real-time collaborative and end-to-end-encrypted sync. Not open source but self-hostable with a single binary and hackable with plugins (custom properties, views, code, etc). [1] https://thymer.com. - Source: Hacker News / 9 months ago
Combining the feel of plain text with real structure is also exactly why we're building an "IDE but for tasks/notes" [1]. With structured apps (task managers, outliners) you lose the illusion of editing plain text, but plain text alone lacks things like structure, links, dates, and collaboration. We've spent the last few years building an editor completely from scratch to keep the ease of text editing while adding... - Source: Hacker News / 12 months ago
