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.
PouchDB 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.

The CouchDB Replication Protocol is implemented in CouchDB itself, so that covers our server component. Then there is the PouchDB project implementing the same protocol in JavaScript targeted at Browser and Node.js applications; that covers your clients and dev servers. - Source: dev.to / 5 months ago
Local first is amazing. I have been building a local first application for Invoicing since 2020 called Upcount https://www.upcount.app/. First I used PouchDB which is also awesome https://pouchdb.com/ but now switched to SQLite and Turso https://turso.tech/ which seems to fit my needs much better. - Source: Hacker News / 12 months ago
Weโve covered this a bit already, so letโs introduce something new about it: CouchDBโs sibling technology, PouchDB. Written in JavaScript, itโs designed to save your work locally on your device and then sync with your CouchDB when youโre back online, and can also be set up to automatically handle conflicts. Where automation wonโt do, you can use CouchDBโs built-in UI, Fauxton, if you havenโt built your own... - Source: dev.to / about 1 year ago
CouchDB on the serer and PouchDB on the client was an attempt at making such an environment: - https://couchdb.apache.org/ - https://pouchdb.com/ Also some more pondering on local-first application development from a "few" (~10) years back can be found here: https://unhosted.org/. - Source: Hacker News / about 1 year ago
Why not just use pouchdb? It's pretty battle-tested, syncs with couchdb if you want a path to a more robust backend? edit: https://pouchdb.com/. - Source: Hacker News / over 1 year ago
