Netlify provides the AI-native platform required to build and scale full-stack applications with 99.99 percent uptime. It enables developers, AI builders, and business stakeholders to use Agent Runners and AI coding agents like Claude Code, Codex CLI, and Gemini CLI to build prototypes, internal tools and production apps.

This ensures every Deploy Preview receives its own database branch forked from production data. Because schema and code always ship together, teams can test and collaborate on live data without manual staging or the risk of broken deployments.. Visibility and security are built into the core of the platform so everyone deploys to the same secure environment. Integrated Observability provides real-time insights into traffic, performance, and function health without the need for external tools. Reliability is guaranteed through instant rollbacks and compliance with SOC 2 Type II, GDPR, HIPAA, and PCI DSS Level 1.
