    Mimo The Minimalistic looking app

    been using mimo for a time and finished Python course as a noob, i can say it's a good experience since they made the course like having a bike with third wheel which is great for home learners, your brain not ready to debug something you don't know, that stage also is tought as a last lesson, how to debug your program, my experience was all in all great, and this coming from me a Lazy Person :)

    ๐Ÿ‘ Pros:    Easy to use|Solid learning method|Repetitive questions explaination|Constantly improving
    ๐Ÿ‘Ž Cons:    English language only

  • A self-hosted Google reCAPTCHA alternative (we ship it)
    The captcha on orkestr is Altcha. Self-hosted, no third-party JS, no Google, no behavioral tracking. Users don't see a puzzle. There's a single checkbox and a quiet "verifying..." while the browser does some math. About a second, total. - Source: dev.to / 3 months ago
