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 512ร—512 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.

Questions & Answers

As answered by people managing netcat and RepDB.

What makes your product unique?

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.

What's the story behind your product?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

9 Best Angry IP Scanner Alternatives Reviewed 2021 (Free & Paid)
Netcat lacks a lot of the documentation you can easily find with software like AngryIP or Nmap which in my opinion is its biggest drawback. If youโ€™re thinking about trying out Netcat, check out our Netcat Cheat Sheet to quickly pull up powerful and useful commands. Netcat is compatible with Windows, Linux, and macOS systems.
Top 5 Best Port Scanners
Netcat is one of the oldest network tools in the "Unixverse", it's been there since 1995, and the last official version is from 2004. Although it has many forks and variants that work pretty well on modern operating systems, like ncat from the Nmap suite, or this alternative Netcat version from Mike Frysinger.

  • TIL: You can make HTTP requests without curl using Bash /dev/TCP
    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
  • could not connect to the rhel-9 from putty in windows machine
    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
  • The HTTP crash course nobody asked for
    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
  • Gaining remote access to a computer with a reverse shell attack in Node.js
    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
