FizzBee

Vibe coding tools are incredibly good at turning prompts into code. But getting them to build software that actually works the way you want is still surprisingly hard.

The common advice is to write better prompts. Be more precise. Provide more context. Plan before you code. Give the AI detailed instructions. But that puts the hardest part back on you. To give precise instructions, you first have to know exactly what you want, including all the decisions, edge cases, and behaviors you haven't thought about yet.

FizzBee helps with that.

FizzBee brings specification-driven development to vibe coding with an advanced Plan Mode that helps you figure out what your software should do before your coding agent builds it.

A typical Plan Mode focuses on how to implement what you've asked for. FizzBee goes deeper into what you're actually asking the software to do. It systematically explores your idea, asks targeted questions, uncovers missing requirements and edge cases, and surfaces ambiguous or conflicting behaviors that need your input.

It is also not another PRD generator that takes what you already know and turns it into a polished document. FizzBee actively looks for what's missing. It helps you discover decisions you didn't know you needed to make.

Even simple apps hide decisions you may not realize you need to make. Terminate a manager. Who takes over their team and pending leave requests? Delete a wiki note. What happens to other notes that link to it? Remove someone from a shared expense. What happens if their balance isn't zero?
