Easy to setup, simple to automate

Approximated treats convenience and simplicity as a first class citizen, going the extra mile to make every step as easy as possible to integrate.

How it works

Approximated creates a dedicated cluster just for you, with edge servers in regions all over the world. These proxy traffic for custom domains to your app at any scale with incredibly low latency.

  1. Create your dedicated cluster Approximated spins up a dedicated cluster, with nodes distributed globally. Traffic is automatically routed through the region nearest users for lightning fast response times. All you need to do is name it.

  2. Call the API, or use the dashboard Connecting a custom domain takes one API call to Approximated. Or, use the dashboard to do the same thing any time. The dashboard will even show you what that would look like as an API call.

  3. Point the domain(s) All that's needed is one DNS A record pointed at your cluster's dedicated IP address. Approximated will automatically create and manage SSL certificates for every domain.

Managed & maintained for you

Convenience isn't enough when it comes to handling custom domains in production - everything needs to be rock solid and reliable.

Approximated has constant monitoring, globally distributed servers, and automatically self-healing clusters so that it's ultra reliable.

Sophisticated monitoring at every level

Approximated is always monitoring the SSL status, DNS resolution, proxy hit status, and more for every domain. No external monitoring or infrastucture required - Approximated includes this for free.

Self-healing clusters with intelligent routing

Frequent health checks for every region of your cluster allow Approximated to find and heal any potentials issues before you or your users run into them. Traffic is automatically be routed to the nearest working region during any repairs to avoid any downtime.

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.

Questions & Answers

As answered by people managing Approximated and RepDB.

What makes your product unique?

Approximated's answer

Approximated makes it extremely easy to add a custom domains feature to any web app, SAAS, marketplace, or platform.

Often, companies can be integrated and live within a few days or less. It's very cost effective, making use of economies of scale and expertise to offer a complete solution at a tiny fraction of the cost to build the same features in house.

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.

Why should a person choose your product over its competitors?

Approximated's answer

Approximated is both easier to integrate, and more cost effective than competitors.

It offers all of the features you care about without building in the cost of those that you don't:

  • Hours or days to integrate, instead of weeks or months
  • You can start small, at a very low price
  • You can scale up to any size without any extra steps
  • You get automatic volume discounts as you scale up, instead of being forced into various enterprise agreements
  • Talk to real developers on staff instead of sales people, if you want
  • Your cluster is dedicated only to you, instead of shared with everyone else like 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?

Approximated's answer

Startups, Scale-ups, dev teams, and devops teams who want to get a custom domains feature launched this week, with rock solid reliability and genuine developer support.

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.

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.
