By utilizing a "Vibe Coding" engine, CodeXero allows users to create, launch, and monetize decentralized applications through a single prompt. CodeXero What does CodeXero do? And why is now the time for it to exist? Vibe Coding engine for Web3, to create, launch and monetize Web3 dApps in single prompt. Now’s a good time for CodeXero to exist because the barrier to entry for Web3 development remains high, and AI-driven tools are essential for unlocking the creativity of non-technical founders. What is your traction to date? How many people does CodeXero reach? We have DAU of more than 40,000 with having more than 250,000 users onboarded. Who does your CodeXero serve? What’s exciting about your users and customers? Anyone/ creator who wants to build a solution/MVP, an idea that sparks in their mind, can be put live into action using CodeXero. What technologies were used in the making of CodeXero? And why did you choose ones most essential to your techstack? While the specific tech stack utilizes proprietary solutions to enable "Vibe Coding," CodeXero is strategically built upon the Sei Network. This choice ensures high-speed transactions and scalability, while the core platform leverages advanced AI models to translate natural language prompts into functional Web3 code. What is traction to date for CodeXero? Around the web, who’s been noticing? CodeXero has generated significant social momentum, evidenced by a flurry of activity and verified mentions on X (formerly Twitter). The project has established itself as a leader in the "Vibe Coding" narrative, garnering coverage from major entities like Gate.io and KuCoin while sustaining a highly active user base. CodeXero scored a 348 proof of usefulness score (proofofusefulness.com/codexero-report) proofofusefulness.com/codexero-report What excites you about this CodeXero's potential usefulness? its a PMF to ship MVPs and monetize them over in web3 and solves the sole problem of creators or people who wish to build but lag due to not having knowledge of Web3 and Coding.
