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.

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.
They make the already great wireguard even better! Installation and configuration is a breeze, can easily connect to machines behind firewall(s) without altering anything.
Definitely made life easier.

Tailscale + exit node for clean IP rotation. - Source: dev.to / 26 days ago
Tailscale is how every machine in the stack is reachable from outside the local network. All four machines are on the same Tailnet, which means I can reach any service from anywhere without opening ports or maintaining a VPN server. - Source: dev.to / about 1 month ago
Still the most reliable setup, honestly. SSH into your machine over Tailscale (or Mosh if your connection is rubbish), reattach your tmux session, carry on. Free, works everywhere, been around forever. The downside is it's all terminal and you need to know your way around. Not exactly mobile-friendly either. Typing SSH commands on a phone keyboard is proper painful. - Source: dev.to / 3 months ago

ClickHouse's BYOC also uses an outbound-only channel for management traffic. Control-plane connectivity from the ClickHouse VPC to the customer's BYOC VPC is provided over a Tailscale connection that is outbound-only from the customer's BYOC VPC. ClickHouse engineers must request time-bound, audited access through an internal approval system; they can only reach system tables and infrastructure components, never... - Source: dev.to / 4 months ago
