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.

IronFunctions is a serverless platform that is open source and falls under the Functions-as-a-Service (FaaS) category, enabling developers to create functions in any programming language and deploy them across a variety of environments, whether they are public, private, or hybrid clouds. It is compatible with AWS Lambda function formats, making it easy to import and run existing Lambda functions without hassle. Tailored for both developers and operators, IronFunctions streamlines the coding process by facilitating the development of small, dedicated functions without the complexities of managing the supporting infrastructure. Operators gain from improved resource efficiency, as the functions utilize resources solely during their active execution, and scalability is achieved simply by adding more IronFunctions nodes as required. Built with Go, the platform employs container technologies to manage incoming workloads by launching new containers, processing the input data, and delivering responses. Additionally, its flexible architecture allows for easy integration with various services, enhancing its utility for diverse application needs.

Oracle Cloud Infrastructure (OCI) Functions provides a serverless computing platform that allows developers to design, execute, and scale applications without the burden of managing the underlying infrastructure. This service is based on the open-source Fn Project and accommodates various programming languages such as Python, Go, Java, Node.js, and C#, which facilitates versatile function development. Developers can easily deploy their code, as OCI takes care of the automatic provisioning and scaling of resources needed for execution. Additionally, it features provisioned concurrency, which guarantees that functions are ready to handle requests with minimal delay. A rich catalog of prebuilt functions is offered, allowing users to quickly implement standard tasks without starting from scratch. Functions are bundled as Docker images, and experienced developers have the option to create custom runtime environments using Dockerfiles. Furthermore, integration with Oracle Identity and Access Management allows for precise control over access permissions, while OCI Vault ensures that sensitive configuration data is stored securely. Overall, this combination of features makes OCI Functions a powerful tool for modern application development.
