Stakly
Stakly.dev is an AI-powered full-stack app builder that lets users design, code, and deploy web applications without writing manual boilerplate. You describe the app idea in plain language, set up data models, pages, and UI components through an intuitive interface, and Stakly generates production-ready code (including React front-end, Supabase or equivalent backend) and handles deployment to platforms like Vercel or Netlify. It offers a monthly free token allotment so you can experiment, supports live previews so you can see your app as you build, integrates with GitHub for code versioning, and is functional enough to build dashboards, SaaS tools, admin panels, and e-commerce sites. While not replacing full engineering teams for deeply custom or extremely large scale systems, Stakly lowers the technical barrier significantly: non-technical founders, product managers, solo makers, or small agencies can use Stakly to create usable, polished apps in minutes instead of weeks.
