RepDB is a one-time-purchase exercise dataset with animations for developers building fitness and workout apps — 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 600+ exercises with flat-style 512×512 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 — 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.
XiuRouter connects applications and AI agents to leading models from GPT, Claude, Gemini, Grok, and other providers through one API. Selected models and service groups currently save over 90% versus provider reference prices, with current prices and savings published on the live pricing page. XiuRouter supports OpenAI Responses, Chat Completions, Anthropic Messages, and Gemini GenerateContent. API keys can be scoped by model access, budget, and expiration, while usage records show model, service group, tokens, status, and cost. Its Agent integration workspace provides protocol-aware setup for 14 apps and verifies real requests against usage records.
RepDB XiuRouterRepDB's answer
RepDB is sold as a one-time download, not a metered API — 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.
XiuRouter's answer:
XiuRouter combines four model API protocols in one service instead of flattening every client into a generic OpenAI-compatible path. It also provides scoped API keys, request-level usage and cost records, and protocol-aware setup for 14 apps. Selected models and service groups currently save over 90% versus provider reference prices; the live pricing page shows the current comparison.
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 — 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.
XiuRouter's answer:
Choose XiuRouter when you need one service for OpenAI Responses and Chat Completions, Anthropic Messages, and Gemini GenerateContent, plus scoped keys and request-level cost records. Its guided integrations cover 14 apps and use each app's actual protocol. Model availability and savings vary, so users should compare the live catalog and pricing for their workload.
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.
XiuRouter's answer:
XiuRouter is for developers, AI application teams, and builders using coding agents or developer tools who want one model API service, protocol-aware client setup, controlled API keys, and transparent request-level usage and cost records.
