ExerciseDB Alternatives 2026: 4 Datasets
ExerciseDB alternative compared with WorkoutX, free-exercise-db, and RepDB, focusing on images, catalogue depth, schema, and pricing.
Building a fitness tracker, I hit the same wall everyone does: where do I get the exercise data? Nothing quite fit, so I built RepDB. This is the short, honest comparison I wish I’d had. Only datasets that ship images — the visual layer is the hard part, and it’s where these products actually differ.
One useful distinction: ExerciseDB.io sells downloadable files; WorkoutX provides a metered API. In the July 2026 samples I inspected, their 0551 GIFs used the same 54-frame artwork. That observation applies to those files, not every asset in either catalogue; details are in the methodology.
The comparison
| ExerciseDB.io | WorkoutX | free-exercise-db | RepDB | |
|---|---|---|---|---|
| Images | GIF; inspected samples have opaque white backgrounds | Hosted GIF; inspected sample has opaque white background | JPG gym photos, mixed sizes | Classic + flat WebP; transparent classic on Standard |
| Colour | 8-bit (256 colours, visible banding) | 8-bit | 24-bit | 24-bit |
| Animation | Animated GIF; Pro offers 4 resolutions | Animated GIF through API | none | 496 exercises with motion clips (Standard); 112 static holds with stills |
| Catalogue | 1,394 entries* | “1,400+” advertised* | 800+ | 608 exercises |
| Languages | EN in inspected sample | EN; DE, ES, FR, Chinese also advertised | EN | EN · DE · ES |
| Pricing | $199 Starter / $599 Pro, one-time | $0–24.99/mo metered, monthly billing | free | $299 Starter / $499 Standard, one-time |
| License | Commercial use with data; no standalone GIF redistribution | API terms; bulk caching restricted | Unlicense; review photo provenance | Commercial license |
Prices and advertised formats checked September 8, 2026: ExerciseDB pricing, WorkoutX plans, and RepDB pricing. Background and frame observations refer to the July samples below.
* Raw entry counts are not directly comparable. The ExerciseDB list inspected in July includes camera-angle variants, (male)/(female) pairs and v. 2 entries. I have not produced a deduplicated count for either competitor.
The images decide it
The Turkish get-up samples inspected in July 2026, side by side. This is a comparison of those files; use the current RepDB motion preview to inspect today’s sample bundle.
Two differences, measured from the actual files:
- Transparency. Opaque near-white GIFs turn into white squares on any dark or themed UI. RepDB’s classic style is transparent WebP — it drops onto any background, masks into round avatars, and re-tints to your brand with one CSS filter:
- Colour depth. GIF caps at 256 colours, which bands on smooth anatomical shading. WebP is full colour.
RepDB’s current catalogue contains 608 exercises: 496 with motion clips and 112 static holds. Standard supplies the motion clips as transparent looping WebP in the classic style. The static holds ship as still images, without animation. Starter includes classic and flat stills; it does not include motion clips.
Browse the current motion preview, download the animation sample, or see the full animation library. The preview is for evaluation; production use requires the appropriate paid license.
Which one, when
ExerciseDB.io — you want a larger raw catalogue as self-hosted files and GIF artwork fits your UI. Starter costs $199 with 180px and 360px GIFs; Pro costs $599 and adds 720px/1080px GIFs, taxonomy and exercise relationships. Its terms cover visuals used alongside the exercise data.
WorkoutX — you prefer a hosted exercise API. The free plan lists 500 requests per month; paid plans run from $9.99 to $24.99 per month on monthly billing. Estimate requests for your app and review the caching and asset-use terms.
free-exercise-db — free hobby or portfolio project, and real gym photography fits your brand. ~800 exercises, Unlicense on the code; the photos’ chain of title is fuzzier, so paid products should look closer.
RepDB — your app needs consistent illustrations, dark mode, brand theming, EN/DE/ES and programming metadata (goals, safety tags, relations). The paid catalogue has 608 exercises in two illustration styles. Standard adds transparent classic assets and motion clips for 496 exercises; 112 static holds remain stills. Inspect the motion preview before buying.
The separate free GitHub snapshot contains 601 exercises as checked September 8, 2026, with flat 512×512 images and commercial in-app use with attribution. Its version can lag behind the paid catalogue. The premium animation sample is evaluation-only.
Methodology & disclosure
Current product check — September 8, 2026. Pricing, advertised formats and terms were rechecked on ExerciseDB, WorkoutX and free-exercise-db. Advertised coverage is not an audit of every file.
Historical file inspection — July 2026. ExerciseDB.io’s public sample bundle included exerciseList.json, 0025.json and GIFs at 180/360/720/1080 px. I downloaded both services’ 0551 GIF (kettlebell Turkish get-up “(squat style)”) and compared it frame by frame: the same 54-frame animation, with WorkoutX’s upscaled to 360px and watermarked. The bench-press GIF inspected then blended between poses. These observations describe those samples; the September product-page check does not constitute a fresh file inspection or establish how much of either catalogue uses that technique.
Current RepDB coverage. Total exercises, motion coverage and static holds are read from the shipping bundle at build time. Motion coverage counts exercise records with motion clips, not necessarily unique files: close variants can share a clip. The July Turkish get-up measurements above are retained as a dated example.
