No description of StackBlitz yet.
I'm a programming tutor, and I kept meeting the same kind of parent. Busy, supportive, but slightly or completely in the dark as to how their kids are learning to code. A lot of them really wanted their kids to learn how to code but at the same time they wanted to know whether their child was...

As answered by people managing StackBlitz and Koder.quest.
Koder.quest's answer:
Koder.quest teaches kids to build real websites through game-style quests, and it gives parents their own dashboard showing what their child built, how active they've been, and time spent. Kira, a built-in AI tutor, guides kids with hints so they think problems through. Most kids' coding platforms show a parent a progress bar. Koder shows the actual work.
Koder.quest's answer:
Live-class programs are effective but expensive and tied to a schedule. Koder is self-paced and more affordable, so kids learn when it suits the family. Broad platforms cover many subjects and often start with drag-and-drop blocks, while Koder focuses on real web development (HTML, CSS, and JavaScript) from the start. Parents also get clear visibility without needing to understand code.
Koder.quest's answer:
Kids aged 10 to 18 who are new to coding and enjoy games, and their parents. The parents are usually non-technical and want to know whether their child is really learning and building something. It also suits homeschooling families and after-school or holiday learning.
Koder.quest's answer:
I'm a teacher who have taught kids to code. Parents kept asking me the same thing: is my child actually learning, are they doing the assignments, have they built anything? Most couldn't tell, because they don't code. So I built Koder.quest, where kids learn through quests and parents can see their child's progress and projects at a glance.

I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.
StackBlitz claims to allow you to code the future in your browser. And after trying it, I’m confident you’ll agree that this web application is extremely useful for coders.
