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.
Domainee is a custom domains API that lets SaaS products offer white-label domains to their users in minutes instead of months - and even sell domains directly inside their app. Connecting a domain takes a single CNAME record, with SSL certificates, renewals, and DNS verification handled automatically, while the Buy-a-Domain API turns domain registration into one API call. The first 50 domains and 100 GB of bandwidth are free forever, with no credit card required.
One-CNAME setup with automatic SSL: End users add a single CNAME at their registrar, and Domainee issues and renews their certificate via Let's Encrypt on the first request โ no DNS validation back-and-forth.
Buy-a-Domain API: Let users search for and purchase a domain without ever leaving your app. One API call registers the domain with your end user as the legal owner, configures DNS, and connects it to your product โ at wholesale price plus a flat $1 fee, with your own markup on top.
Stripe-shaped REST API: POST /v1/domains creates a domain, returns the CNAME, and fires a domain.verified event over HMAC-signed webhooks the moment DNS lands. Bearer keys and idempotency keys included.
Full domain lifecycle endpoints: DNS, nameserver, and renewal management via API, so your users never have to log into a registrar.
Hosted MCP server for AI agents: Drop one config block into Claude, Cursor, or any AI agent and get 11 ready-made tools to list, create, and verify domains in plain English โ no code change.
Real free tier: 50 custom domains and 100 GB of bandwidth every month, free forever. The free quota stays free even after you scale past it.

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.
Domainee.dev's answer:
I built Domainee because I was tired of seeing developers waste months building the same custom domain and SSL infrastructure for every new project. I wanted to create a "set it and forget it" solution that handles the complex plumbing of DNS and certificates through a single, clean API. Domainee was born to turn a major technical headache into a copy-paste task, allowing founders to focus on their core product instead of infrastructure.
RepDB'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
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.
