Netlify is the AI native web platform where agents and developers build together. Over 15 million developers and teams use it to build, launch, and scale web applications on a single platform, from independent builders to cross-functional teams at Bolt, Figma, Mattel, and Riot Games. Whether you're writing code or working with AI, Netlify takes you from prompt to live production URL in one workflow. Leading AI coding agents like Claude Code, Codex CLI, and Gemini CLI run directly inside the Netlify dashboard, which is agent-agnostic by design. Underneath sits managed Postgres with isolated branches per Deploy Preview, serverless functions, edge compute, and a global CDN. Every modern web framework is supported. That last part matters. Most AI prototyping tools hit a wall when it's time to ship. Teams build something quickly, then hand it back to engineering to rebuild on real infrastructure before it can scale. Netlify skips that step. The app you ship on day one is the app that scales. Netlify's CEO and co-founder, Mathias Biilmann, coined the term agent experience (AX) in January 2025. The company's long-term strategy is built around being the best place for agents and the humans directing them to build software together. The business model reflects that bet. Netlify was first in the category to pair credit-based usage tiers with flat, unlimited seats. Developers, PMs, marketers, and internal builders can all join the same plan for free and build alongside AI agents. It's a PLG motion designed for bottom-up enterprise expansion, with consumption driving growth instead of seat counts.
