vly.ai
Free AI full-stack web app builder, now part of Freebuff Web—unlimited use, no subscriptions.
vly.ai (Freebuff Web) is the only completely free AI app builder we've seen, with no credit limits or subscriptions. Its realtime-first architecture, multiple coding agents (vly agent 2.0, Claude Code, OpenAI Codex, Gemini CLI), and managed Convex backend make it a strong pick for non-technical users and hackers. Compared to Lovable (starts at $25/mo) and Replit (Starts at $3 - but rising credit issues), it offers substantial savings. However, it's web-only, requires GitHub signup, and the standalone product is gone—it now lives inside Freebuff Web. If you're fine with those trade-offs, it's a no-brainer. If you need mobile apps, self-hosting, or enterprise SLAs, look at alternative build.

Skip vly.ai if you need native mobile app development, a backend framework other than Convex/React, or enterprise-level support and SLAs—since vly.ai is web-only, sticks to React/Convex, and is now a free product with no dedicated enterprise tier.
Since vly.ai is now free, there are no hidden costs, but you may incur costs from third-party services you integrate (e.g., Stripe transaction fees, OpenAI API usage).
vly.ai is completely free for unlimited use, making it ideal for solo developers, startups, and students who want to build web apps without upfront costs. It's cheaper than Lovable ($25/mo) and Replit ($3/mo) but offers fewer platform features than paid competitors.

About vly.ai
vly.ai is an AI-powered web development platform that turns natural language prompts into production-ready web applications. You describe your app idea, and the platform's AI agents generate, iterate, and deploy your project using React, Vite, Convex, and Tailwind CSS. It provides a fully managed backend with a real-time database, server functions, file storage, and live sync, plus version control, custom domains, and one-click publishing. The platform supports multiple coding agents, including vly agent 2.0, Claude Code, OpenAI Codex, and Gemini CLI, giving you flexibility in how your code is generated. It also integrates with 1,000+ services like Stripe, OpenAI, Twilio, GitHub, Slack, AWS, SendGrid, and Notion. After being acquired by Freebuff, all subscriptions were cancelled, making the service completely free with no credit system or usage limits. You sign in with GitHub, and existing users can transfer their projects to Freebuff Web. It's ideal for non-technical users, startups prototyping MVPs, hackathon participants, and developers who want to accelerate web development without paying per credit. However, it only builds web apps, requires GitHub login, and the standalone vly.ai product is no longer separate—it's now just Freebuff Web.
Behind the Verdict
vly.ai, now part of Freebuff Web, is an AI-powered platform that builds full-stack web apps from a text prompt. Its core strength is that it is completely free—no subscriptions, no credit system, and no usage limits. This is a stark contrast to competitors like Lovable (which starts at $25/mo and has users reporting rising credit usage) and Replit (which starts at $3 but has credit issues). The platform supports multiple coding agents (vly agent 2.0, Claude Code, OpenAI Codex, Gemini CLI) so you can choose how your code is generated. It uses a realtime-first stack with Convex for the backend, providing a real-time database, server functions, file storage, and live sync—features that are typically paid or limited in other builders. You also get version control, custom domains, one-click publishing, and visualizations of your backend to help you understand the generated code. However, there are trade-offs. The platform only builds web apps—no mobile output. It requires a GitHub login, which may be a barrier for some. The standalone vly.ai product is gone; everything now lives in Freebuff Web, so if you prefer to keep your projects separate, that's a change. The tech stack is fixed to React/Convex/Tailwind, so if you need a different framework, you're out of luck. The integration library is extensive (1000+), but not every niche service is covered. For most people, especially those prototyping or learning, the free, unlimited access is a huge win. But if you need enterprise support, SLAs, or on-prem deployment, this isn't the tool.
