RepDB
Open-source serverless enterprise CMS platform. Includes a headless CMS, page builder, form builder, and file manager. Easy to customize and expand. Deploys to AWS.
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.
Webiny 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.

Even Strapi needs to be hosted somewhere, and that usually involves a recurring fee. I've had great success over the past 2 years building blogs using http://webiny.com, and because they get low traffic, I've only ever had 1 bill from AWS that was around 80 cents US. Source: about 4 years ago
Strapi is awesome, I've been a fan of the project since its early days. However, I've been closely watching Webiny too. It's easier to host because you don't have to worry about running Docker containers or installing MongoDB on your local machine. Instead you put it on your AWS account (can be done with a few clicks), define your content models once it's there and you then only pay for usage. http://webiny.com. Source: over 4 years ago
Yeah I hear you, SAAS CMS platforms can get prohibitively expensive really quickly after the initial free tier expires. I've found hosting Strapi (or similar) on Heroku has saved me the cost of keeping a server instance running, which usually would cost $5-10 per month. However, the most cost effective for me so far has been Webiny. It's serverless so you install it on AWS and typically don't pay as much (if... Source: over 4 years ago
Otherwise if you want a framework to build on, there's Redwood (which works particularly well on Netlify and Vercel) or Webiny (for AWS, Azure and others). - Source: dev.to / almost 5 years ago
