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.
netcat
RepDBNetcat is recommended for network administrators, cybersecurity professionals, system engineers, and IT enthusiasts who need a flexible and straightforward tool for network diagnostics, data transfer, or security testing purposes.
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.
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.

Guess streams was a mixed analog / digital world thing[0]. Is 'curl' the higher order wave crest of LC_NETWORK (aka 'sane' http protocol reference to type bundled 0,1,2 file descriptors) One can have curl as a bash loadable routine without the need to recompile bash. Headless or not, much more sane[4] than ctypes.sh[1] as epilog/prolog handled withing context of curl module/program. More relevant logic level... - Source: Hacker News / about 2 months ago
If you don't like using telnet, that's fine. Don't use it. There are plenty of other options available. Use netcat. Or use netcat. Or use netcat. Or read and write directly to /dev/tcp/hostname/port using shell constructs. Or run openssl s_client if you suspect something complicated is listening on the other end. There is more than one way to do it and ways that are not your way still work. Source: about 3 years ago
Reminder, there are many different netcats, here are some of the most commons: - netcat-traditional http://www.stearns.org/nc/ - netcat-openbsd : https://github.com/openbsd/src/blob/master/usr.bin/nc/netcat.c (also packaged in Debian) - ncat https://nmap.org/ncat/ - netcat GNU: https://netcat.sourceforge.net/ (quite rare) To prevent any confusion, I like to recommend socat: http://www.dest-unreach.org/socat/. - Source: Hacker News / almost 4 years ago
A common tool to execute a reverse shell is called netcat. If you're using macOS, it should be installed by default. You can check by running nc -help in a terminal window. - Source: dev.to / about 4 years ago
You could try using Ncat on Windows or netcat on Linux, though it's a command-line only tool if that matters. Source: over 4 years ago
