LocalStack has raised $25 million in Series A funding led by Notable Capital, with participation from existing investors CRV and Heavybit.

Their virtual environment allows developers to build and test cloud applications by  eliminating the friction of cloud-based testing.

LocalStack’s platform enables developers to run a complete AWS environment on their laptops, reducing cloud costs. 

“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.

“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,” added Waldemar Hummer, co-founder and Co-CEO.

The platform currently supports over 100 AWS services, emulating actual 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 Capita and new LocalStack board memberl. “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. “

The funding will accelerate LocalStack’s go-to-market expansion in the U.S., and fuel continued product development, allowing them to offer  chaos engineering and application resiliency testing as well as reducing the complexity and risk of maintaining AWS development accounts while improving product velocity.
