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 512ร—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 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.

Possible disadvantages of Formspark

  • Cost
    While there is a free tier, advanced features and higher usage limits require a paid subscription, which may not be ideal for all budgets.
  • Limited Offline Functionality
    As a cloud-based solution, Formspark requires an internet connection to function, which may be a limitation for users needing offline access.
  • Dependency on a Third Party
    Relying on an external service means that any downtime or service issues with Formspark can affect form availability and data collection.
  • Privacy Concerns
    Since data is routed through and stored by Formspark, some users may have concerns about where their data is stored and how it is used.
  • Feature Limitations
    Compared to building a custom solution, Formspark may lack certain advanced features or specific customizations some developers might seek.

Questions & Answers

As answered by people managing Formspark and RepDB.

What makes your product unique?

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.

What's the story behind your product?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

  • Self-Hostable Form Back End โ€“ OSS Alternative to Formspree
    In case others are looking for a cheaper alternative to Formspree, I've been using https://formspark.io/ for all my websites [1] [2] [3] I paid $25 a few years ago (can't even remember when) and I still have 47k out of the 50k submission credits I bought. But I love to see a self-hostable alternative available, especially one that's as easy to use as running a `docker-compose` command. Sometimes you just need that... - Source: Hacker News / over 1 year ago
  • How do I receive emails from users who want to contact me
    Formspark is a great service for this with a generous free tier. If you end up scaling up and need more and/or advanced transactional emails you may consider an email API like SendGrid, Amazon SES, or Waypoint. Source: almost 3 years ago
  • Email API other than Mailgun or SendGrid
    Try https://formspark.io/, works good for me ๐Ÿ‘. Source: over 3 years ago
  • free-for.dev
    Formspark.io - Form to Email service, free plan allows unlimited forms, 250 submissions per month, support by Customer assistance team. - Source: dev.to / over 3 years ago
  • where/how to find web dev help for -designing- and building forms?
    You don't necessarily need to hire a dev to build these things. Perhaps you could train an assistant to use typeform.com or formspark.io and embed those forms in the right places on your website? Source: over 4 years ago
