No description of DevTools Advanced yet.
Most side projects don't fail because the developer isn't good enough. They fail because there's no structure, no real deadline, and nobody watching when you skip Day 4. MVP Builder is a structured 13, 21 or 30-day sprint for developers with a full-time job whose side project is stuck. Not a...

MVPBuilder.io's answer:
AI will give you a plan in ten minutes and will not notice when you skip Day 4. What is missing is not another plan, it is a checkpoint someone else reads. The daily prompt is calibrated to your own project context rather than generic advice, and the decision to take you on is made in a call, not by a form — vague scope gets turned down there, because a sprint that starts wrong produces nothing worth showing.
MVPBuilder.io's answer:
Developers with a full-time job and a side project that has been almost done for months. Not beginners, not people looking for someone to build it for them. The requirement is that you own the implementation and can put three to five hours a week into it, spread across several days rather than in one block.
MVPBuilder.io's answer:
The milestone is enforced, not tracked. On day 13, 21 or 30 you attach a URL or a file, and a person reads it against a goal that was written down before day one and frozen. No proof, no continuation: the sprint pauses. Everyday check-ins stay voluntary on purpose — the point is not attendance, it is that something exists at the checkpoint.
MVPBuilder.io's answer:
I built the enforcement first and then ran it on myself: a 21-day sprint as a participant, with the goal written down and frozen before day one. I missed one of my four criteria and published that alongside the three I met. The product exists because I did not trust my own account of my progress, and there was no reason anyone else should either.
