RepDB
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 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.
Dinit 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.

I wrote up some issues with service reliability here https://github.com/andrewbaxter/puteron/?tab=readme-ov-file#origin-story Design-wise, I think having users modify service on/off state *and* systemd itself modify those states is a terrible design, which leads to stuff turning back on when you turn it off, or things turning off despite you wanting them on, etc. (also mentioned higher up) FWIW after making... - Source: Hacker News / 6 months ago
Still, I applaud efforts like s6 and Dinit as competition is a good thing in general. I hope they'll continue to be improved upon until they've become viable alternatives to systemd for most users. Source: about 3 years ago
You can download dinit from github https://github.com/davmac314/dinit. (also read everything about it) Do a simple make && make install which should install it to /sbin/dinit No need to remove systemd or openrc. /sbin/init should be symlinked to whatever init system you use. Read the instructions on dinits page. All the services go into /etc/dinit.d. And you can "dinitctl enable servicename" to enable it. I... Source: about 3 years ago
It got mass-adopted while being imperfect, so that's to be expected. Thankfully its inception and the criticism that followed have paved the way for the likes of dinit and s6. Source: about 3 years ago
I use dinit do manage services on my home server. One of them is Caddy, that shares TLS/SSL cert state with my remote server by using Redis on said remote server. However, since this means that I need to have established a remote connection first before starting Caddy, I would like to know of a method to check if tailscale has in fact finished connecting.
