The problem of inefficient diff viewing is moderately clear, there is some gap in keyboard-centric LSP-supported tools, but willingness to pay is uncertain and the product is technically feasible for a solo developer.
Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
The value to users is moderate given niche appeal, the price sensitivity is unclear, and the market size is limited but focused.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
The idea addresses a specific developer pain point but lacks clear evidence of strong demand or monetization potential.
Viral Frameworks
Hook strength, shareability, and how cheaply it can be tested.
The product fits a technical niche with some differentiation but may struggle to scale beyond power users.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.
The idea targets a real developer workflow problem with a focused solution, but market size and monetization remain open questions.
