As answered by people managing JSON Generator and Foundstep.
Foundstep's answer:
Foundstep's answer:
I'm a solo developer with 50+ started projects and less than 10 shipped. I realized the problem was never motivation or skill. It was the lack of a system that forced me to validate ideas before building, stop adding scope mid-project, and actually decide when something is done. I couldn't find a tool that did this, so I built one. FoundStep came from my own graveyard of abandoned projects.
Foundstep's answer:
Next.js, React, TypeScript, Tailwind CSS, and Node.js. The frontend is built with Next.js 15 using the App Router. The UI uses shadcn/ui components. The backend runs on Node.js with a REST API.
Foundstep's answer:
Most project tools give you a blank canvas and let you organize however you want. FoundStep does the opposite. It forces you through a fixed lifecycle: validate your idea, decide if it's worth building, lock your scope, and ship. You can't skip steps. If you want to add something after locking scope, you have to unlock it and write a reason that gets logged permanently. That friction is the point. It stops scope creep before it kills the project.
Foundstep's answer:
Tools like Notion, Linear, and Trello are built for teams and give you full flexibility. That flexibility is exactly why solo developers never finish anything. FoundStep removes the flexibility on purpose. It has a 7-step validation questionnaire so you don't build bad ideas, scope locking so you stop adding features mid-build, and a permanent log of every time you broke your own rules. No other tool does this. It's not a better project manager. It's a system that makes you ship.
Foundstep's answer:
Solo developers and indie hackers who start side projects but rarely finish them. People with 10+ repos collecting dust. Developers who code nights and weekends, don't have time to set up complex tools, and need a process that holds them accountable without adding overhead.

So I generated a random JSON file and tried parsing it. It doesn’t error, but whenever I do a println(root.Object().Value().String()), I get a panic: wrong type. If I do a println(root.Object().Present()), it prints false. So seems like... Source: over 3 years ago
