CheckIO is a web site with a mission: To teach JavaScript and Python coding skills through a game-playing interface. It is designed to teach new skills or improve existing skills through completing challenges.
Cachely is a managed implementation of self-hosted remote cache for monorepos. Speed up CI, prove how much time and cost you saved, get build optimization suggestions, safe from cache poisoning (CVE-2025-36852). Turborepo and Bazel on the roadmap.

Cachely is the managed self-hosted remote cache for Nx and Turborepo - the cache backend you'd otherwise build and run yourself, hosted for you on Cloudflare's edge (R2). It's a drop-in replacement for a DIY @nx/s3-cache / S3 bucket setup: point your build tool at Cachely with a token and two environment variables, and share build cache across CI and every developer's laptop.

Unlike a self-hosted cache, Cachely enforces read-only tokens at the API, so pull-request and fork builds can read but never write - closing the Nx cache-poisoning attack (CVE-2025-36852). It adds ROI reporting (the real build minutes and dollars the cache saved), per-tool insights, and build-optimization suggestions on top.

Pricing is a flat per-workspace subscription with no per-seat fees - add every developer, bot, and CI actor without watching the bill. Cachely never stores your source code; it caches only task outputs and their content hashes. Nx and Turborepo today; Bazel on the roadmap.

    Some users may find the difficulty of certain challenges to be either too high or too low, making it harder to find problems that are appropriately challenging for their skill level.
  • Limited Career Development Features
    The site focuses primarily on coding challenges and lacks extensive resources for job placement or career development compared to other platforms like HackerRank or LeetCode.
  • Less Comprehensive Tutorials
    While CheckIO provides educational missions, it may not be as comprehensive in tutorials and explanations compared to other dedicated learning platforms like Codecademy or Coursera.

  • I am stuck!
    Have you heard of CheckIO (https://checkio.org/)? They have a gameified "Mario world" of coding challenges that are smaller and come with more explanation, tests to guide you through edge cases and provide hints. The challenges start from total beginner and progress to more advanced. And best of all, after you solve a problem they show you what other people do. I highly recommend this for you.

  • I feel like I may not be smart enough to get into the cybersecurity space
    Cyber isn't gonna be a light switch, where you can flip it and be good. Don't be too hard on yourself. Start with some hands on stuff like https://tryhackme.com or checkio.org. You could look at certs like Security+ or CySA+ for some direction. It took me years to get into cybersecurity, and I still don't feel like I know anything. Source: about 3 years ago
