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...

As answered by people managing MVPBuilder.io and Devrian.in.
MVPBuilder.io's answer
Next.js, Supabase, Vercel
Devrian.in's answer:
DEVRlAN is built with Next.js and React using TypeScript. The interface uses Tailwind CSS with CSS variables for the design system, while Framer Motion handles complex UI motion and lucide-react provides the icon system.
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.
Devrian.in's answer:
DEVRlAN is designed for developers who want quick, focused utilities without creating accounts, installing software, or sending sensitive data to unnecessary third-party services. Its browser-native workflow keeps common tasks accessible in one place while prioritizing local processing and simplicity.
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.
Devrian.in's answer:
DEVRlAN is primarily built for software developers, engineers, and technical users who regularly need quick utilities for tasks such as JSON formatting, JWT debugging, encoding and decoding, UUID generation, regex testing, URL encoding, and hashing.
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.
Devrian.in's answer:
DEVRlAN combines practical developer utilities with a privacy-first, browser-native approach. Tools such as JSON formatting, JWT debugging, Base64 encoding, UUID generation, regex testing, URL encoding, and hashing can be used directly in the browser, with local processing whenever possible and no account or installation required.
MVPBuilder.io's answer
Devrian.in's answer:
DEVRlAN is currently an independent developer project and does not have publicly disclosed major customers. The product is available for developers and technical users to use directly.
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 so that every participant gets the same setup: a goal frozen before day one, and proof at each milestone that a human reads.
Devrian.in's answer:
DEVRlAN started as an independent developer project focused on making common technical tasks faster and simpler. The goal is to bring useful browser-native utilities into one focused workspace, while keeping privacy and local processing at the center of the experience. It is being developed based on practical developer needs and feedback.
