The Pattern Library
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.
What it does โข Digital catalog magic: drag-n-drop a PSD, TIFF or JPEG and PATTERNISSE auto-tags, files, and shelves it โข Photo-real mockups: see your pattern on dresses, shirts, bedding, wallpapers, suits without opening Photoshop โข Huge GB file sharing: no more โyour attachment is too largeโ sad-trombone emails or pay for WeTransfer โข Analytics dashboard: stalk (politely) which patterns your clients binge-view at 2 a.m. so you can design more of what sells โข Easy PDF invoices & payment links: make invoices fast, share secure pay links, and get paid without chasing clients

PATTERNISSERepDB'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.
PATTERNISSE's answer:
PATTERNISSE puts many jobs in one place. Drop in a pattern and it tags itself, stores it in a neat online shelf, and shows it on a dress or wall right away. You can send big files with one link, see which designs a client opens, and add a pay-now button without leaving the page.
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.
PATTERNISSE's answer:
Most designers jump between four or five apps. PATTERNISSE does the same work in one login, so you spend less money, lose fewer files, and close deals faster.
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.
PATTERNISSE's answer:
Surface and pattern designers, wallpaper makers, textile teams, and licensing agents, anyone who works with repeating artwork and big image files.
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.
PATTERNISSE's answer:
Our founders were pattern designers fed up with messy folders, printed look-books, and late payments. They built a small fix for themselves, friends wanted in, and PATTERNISSE grew from there.
PATTERNISSE's answer:
AWS keeps the files safe and scales as you grow. OpenAI add some AI magic. Stripe handles payments and invoicing. The site itself is written with Typescript, SQL and HTML.
PATTERNISSE's answer:
One of the five biggest wallpaper brands in Europe, multiple large U.S./Portuguese textile mill, and hundreds of indie pattern studios rely on PATTERNISSE every day (names under NDA).
