FounderDeck estimate
Low confidenceThis FounderDeck signal estimate of $35,000 reflects Usagi Engine's clear product, polished execution, and strong utility for a specific niche of 2D pixel art game developers. The project offers significant value to its users through rapid prototyping features and an open-source model. The estimate is not higher because the engine is explicitly free, dedicated to the public domain, and its monetization primarily relies on 'buy me a coffee' donations, which limits its traditional commercial startup valuation despite its technical merit.
Valuation date: 2026-06-05. Estimate generated from public signals.
