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.
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.

Postman dominated API development for over a decade because it made REST discovery, testing, and documentation accessible without deep command-line expertise. But 2026 has flipped that advantage. The rise of CLI-native, scriptable, and programmatic API toolingโdriven by projects like Arc, HTTPie, and cURL's modern revitalizationโhas made the terminal the preferred workspace for 68% of backend engineers (per the... - Source: dev.to / 2 days ago
You may like https://httpie.io/ if you've not memorised all the curl flags already. The CLI tools way of making requests with headers and post bodies is really nice in my opinion `http PUT pie.dev/put X-API-Token:123 name=John`. - Source: Hacker News / 5 months ago
For developers who prefer command-line interfaces, HTTPie offers an elegant alternative to curl with superior offline capabilities. The --offline flag enables request construction and validation without network transmission. - Source: dev.to / 10 months ago
Curl's UX is very dated and I wouldn't recommend it to any new user. Use many alternatives like httpie [1] or something like curlie [2] which is just an UX wrapper around the same libcurl. Httpie also has a postman-like web interface. 1 - https://httpie.io/. - Source: Hacker News / 10 months ago
For developers who prefer terminal-based workflows, HTTPie offers a more user-friendly alternative to curl while maintaining the efficiency of command-line tools. Its intuitive syntax and colorized output make API testing from the terminal more accessible and productive. - Source: dev.to / over 1 year ago
