RepDB
SimpleLogin is an open-source email alias solution that allows you to protect your email via "email alias": just use alias instead of email address everywhere. Emails sent to an alias are forwarded to your mailbox. If you want to reply, just hit "reply" and the reply will come from your alias, keeping your personal email hidden. You can also send emails from alias, making alias just a "normal" email address. Because of that, alias can be used as business email: all SimpleLogin team emails are actually aliases :).
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 250 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.
SimpleLogin RepDBRepDB'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:
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 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.
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.
Works great. I've been a premium subscriber for a while and everything works well. New features are released frequently.
SimpleLogin is the best email alias service. Having used it for several months now, for both my personal and pro emails and everything just works.
The team is very reactive and new features are constantly released. They are also transparent about how emails are handled.
Open source and can be self-hosted, I guess we cannot ask more from an email service.

Simple Login (SL), Addy (AD), and DuckDuckGo Email Protection (DDG) are the 3 alias email services I use. Both SL and AD can send and receive. DDG only receives. You can disable the sending direction and simply allow the forward service to run. I believe you will be able to handle this technological challenge. SL and AD are free for 10 aliases, but AD also includes PGP in the free tier. DDG allows for unlimited... - Source: Hacker News / about 2 years ago

>Email aliases, mailing lists, subaddressing and catch-all addresses support. Another feature that would be nice to have built-in is masked hide-my-email aliases for privacy like the cloaked email services from iCloud, FastMail, SimpleLogin, Cloudflare email routing, etc.[1] For now, I use the typical aliases addresses in Dovecot but it doesn't hide the real email when replying.
