LocalStack Secures $25M Series A Funding to Give Developers Control Over Cloud Development

LocalStack, a leader in local cloud development environments, has announced the successful completion of a $25 million Series A funding round led by Notable Capital, with support from CRV and Heavybit. This investment is set to drive forward LocalStack's mission to revolutionize cloud development by putting control back into the hands of developers, eliminating the costly and time-consuming reliance on cloud-based testing.

LocalStack’s platform enables developers to run a full AWS environment directly on their laptops. This unique approach accelerates development cycles, cuts down on cloud costs, and is quickly becoming essential in the developer community. LocalStack currently powers over 8 million weekly sessions and has amassed more than 280 million Docker pulls. With a growing customer base of over 900 companies, including industry leaders like SiriusXM and Chime, the platform is proving itself as the go-to choice for local cloud development.

“The centralized nature of cloud computing has created unprecedented complexity and costs for developers, who spend countless hours waiting for cloud-based tests to complete,” said Gerta Sheganaku, co-founder and Co-CEO of LocalStack. “Our platform fundamentally transforms the developer experience by enabling teams to test locally, cutting deployment times from 28 minutes to 24 seconds while significantly reducing AWS spend. We're putting control back in developers' hands, giving them the flexibility and speed they need to innovate,” adds Waldemar Hummer, co-founder and Co-CEO of LocalStack.

The funding arrives as organizations increasingly confront rising cloud costs, with annual expenditures already surpassing $79 billion, and grapple with the inefficiencies of cloud-based development. By providing a localized AWS testing environment, LocalStack eliminates the need to spin up cloud resources, replacing them with an isolated sandbox that enables rapid iteration and seamless collaboration. Supporting over 100 AWS services with near-exact emulation, LocalStack gives developers a reliable and cost-effective alternative to cloud environments.

“LocalStack stands out for its rare combination of bottom-up developer love and clear enterprise value,” said Glenn Solomon, Managing Partner at Notable Capital. “With over 56,000 GitHub stars, 25,000 Slack users, and 500+ contributors, LocalStack has built a vibrant community alongside its rapidly growing enterprise customer base. While they've established themselves as the de facto standard for AWS local development, their recent preview release for Snowflake showcases their broader vision to revolutionize cloud development across all major platforms. We're thrilled to partner with Gerta, Waldemar, and the entire LocalStack team as they transform how developers build for the modern multi-cloud world.”

LocalStack’s growth trajectory reflects its dedication to transforming cloud development processes. The company, founded in 2017 as an open-source project, has expanded into a comprehensive platform, boasting over 52,000 GitHub stars and an extensive community of 25,000 Slack users. Rooted in open source, LocalStack’s mission is to give developers complete control over their environments, allowing them to run, test, and debug cloud services locally. This control reduces the complexity, cost, and environmental impact of cloud development, empowering developers to focus on innovation and efficient testing.

With the new funding, LocalStack aims to accelerate its U.S. market presence and invest further in developing new features such as chaos engineering and application resiliency testing. These innovations will continue to enhance developer productivity, freeing up valuable time previously lost to cloud setup and permissions management. By emulating cloud services locally, LocalStack also opens doors to advanced workflows, including seamless collaboration through Cloud Pods, a feature that saves and restores infrastructure states for enhanced team productivity.

LocalStack’s platform has fundamentally altered the development landscape by decoupling AWS development from cloud dependency. By enabling developers to run complete stacks locally, the platform removes the need for sandbox accounts, automates IAM policies, and allows for rapid, risk-free testing. This is especially valuable for engineering teams like that of Xiatech, where Rick Timmis, Head of Engineering, notes, “Our engineering team utilizes LocalStack to provide a complete, localized AWS environment where developers can build, test, profile, and debug infrastructure and code ahead of deployment to the cloud.”

As LocalStack continues to enhance cloud development by focusing on developer experience and efficiency, the company’s commitment to putting developers first and promoting a collaborative, innovative workplace remains central. LocalStack’s technology is not just an emulator; it’s a comprehensive toolset designed to streamline cloud development, enabling faster deployments, reduced AWS costs, and a smoother workflow for global dev teams.

This latest funding round positions LocalStack to further expand its offerings, solidifying its role as a critical asset for teams aiming to innovate without the friction of traditional cloud development constraints. As they look toward a future where cloud development is streamlined and simplified, LocalStack is setting a new standard in the developer-first approach to cloud services.
