Leap.new, developed by the ex-Spotify team behind the open-source backend framework Encore, has launched as the first AI-powered developer agent capable of creating and deploying production-grade full-stack applications directly to a user’s AWS or Google Cloud environment. This innovative tool addresses the limitations of existing AI app builders by focusing on real-world engineering needs.

Builds and deploys production-grade apps to AWS or Google Cloud.
Offers infrastructure-as-code and full observability for developers.
Unlike other AI tools, avoids proprietary platform lock-in.
Features safe testing in preview environments and Git integration.
Developed by ex-Spotify team behind Encore with $4M funding.
Leap.new, launched on May 28, 2025, in Stockholm, introduces a groundbreaking AI-powered developer agent designed for professional engineers. Unlike other AI app builders that focus on simple frontends or lock users into proprietary platforms, Leap.new creates production-grade applications with robust backend logic, APIs, and databases. “We built Leap.new because existing tools only scratch the surface, they can generate a cool frontend UI, but they fall apart when you need real backend logic or cloud infrastructure,” said Marcus Kohlberg, founder of Leap. This tool empowers developers to maintain control over their architecture and cloud environment.
Leap.new defines infrastructure-as-code by default, creating databases, microservices, and event systems with a cloud-agnostic declarative layer. It provides full observability through live architecture diagrams and an autogenerated service catalog with API documentation, enabling developers to inspect and understand the AI-built systems. This approach ensures scalability and transparency, addressing the complexities of real-world application development.
Designed for developers, Leap.new starts with a prompt and supports iterative development with versioning, diffs, and manual edits, with all code stored in the user’s Git repository. It offers safe testing in preview environments, allowing features to be tested in isolation before deployment. The platform supports cloud-native deployment to AWS or Google Cloud via Encore Cloud or self-hosting through Docker, ensuring flexibility and integration with existing workflows.
Developed by the team behind Encore, which has over 10,000 GitHub stars, Leap.new is led by founders Marcus Kohlberg and André Eriksson. Since its inception in 2021, Encore has raised $4 million in pre-seed funding from notable investors like Scott Belsky (Behance) and David Cramer (Sentry). This expertise underpins Leap.new’s ability to deliver a developer-focused solution that meets enterprise-grade requirements.
Leap.new’s launch marks a significant advancement in AI-driven software development, offering a robust, developer-centric solution for building and deploying full-stack applications. By prioritizing control, scalability, and integration with AWS and Google Cloud, Leap.new sets a new standard for AI-powered development tools, empowering engineers to create production-ready applications efficiently.
