CTFreak allows you to centralize, maintain and schedule various types of tasks:
Local command task to run a command directly on the host server on which CTFreak is installed.
Command task to run the same command on several servers (aka nodes) through SSH.
Bash script task to run the same bash script on several unix servers through SSH.
Powershell script task to run the same powershell script on several windows servers through SSH or WinRM.
Ansible playbook task to run an ansible playbook targeting several servers through SSH or WinRM.
SQL script task to run the same SQL script on several databases.
SQL report task to generate reports with charts and tables from SQL queries.
HTTP Request task to call API endpoints (webhook, ping, ...).
Workflow task to execute other tasks, sequentially or concurrently.
And to receive notifications (slack, teams, telegram, mattermost, discord, email, ntfy) based on their executions.

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.

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.
Very convenient for managing all batch processing tasks in a single tool for our infra, which combines Windows and Red Hat servers.

If you can wait two or three weeks, I'm finalizing sso support on https://ctfreak.com (yes, I'm the author). It will be available in the free edition with some limitations. Source: over 3 years ago
