$25M Series A to Empower Developers and Accelerate Enterprise Cloud Development

Today, we’re honored and thrilled to announce that LocalStack has raised $25 million in Series A funding led by Notable Capital, with participation from existing investors CRV and Heavybit. This milestone marks a pivotal moment for LocalStack, our customers, and our community as we continue our mission to give developers control over cloud development and help enterprises build faster, better, and more efficiently.

The De Facto Platform for Local Cloud Development

Our journey began with a simple yet radical idea: developers should be able to run complete AWS environments on their local machines. We believe that cloud development should be quick, seamless, and free from unnecessary constraints.

Today’s developers are heroes in a high-stakes battle against the clock. Every hour spent waiting for cloud-based tests to run is an hour they could be innovating, experimenting, and pushing boundaries. This is not just about speed - it’s about autonomy.

Over the past years we’ve been able to build a solid product that has even swayed the minds of some of the biggest skeptics, and we’ve seen LocalStack become the de facto platform for local cloud development, embraced by a global community of developers looking to streamline their workflows and reduce cloud dependencies.

The flexibility to develop and test locally empowers teams to operate at their full potential. With 8 million weekly sessions, 280 million Docker pulls, and over 900 paying customers - LocalStack is changing how the world develops cloud applications.

Empowering Enterprises to Build at Speed

Enterprises today face mounting pressure to innovate rapidly while controlling costs and maintaining product reliability. LocalStack addresses these challenges by enabling development teams to run complete AWS environments locally, which significantly speeds up development and testing cycles.

The result? We’ve seen deployment times reduced from 28 minutes in the cloud to just 24 seconds locally for some workloads. This capability fundamentally transforms development workflows, allowing teams to iterate quickly and deliver high-quality software without being held back by cloud constraints.

Companies such as SiriusXM and Chime are among many customers that trust LocalStack to enhance their development processes. Our platform not only optimizes speed but also provides cost efficiencies and better developer autonomy, ensuring that enterprises stay ahead in a fast-evolving digital landscape.

A Thriving Community, Driving Innovation

Our open-source origins and commitment to the developer community have been central to our growth. With 56,000 GitHub stars, 25,000 Slack members, and 500+ contributors, we are fortunate to have built an active community that resonates with our mission and is as passionate about LocalStack as we are.

This strong foundation has been pivotal in helping us stay true to our developer-first approach, ensuring that our platform evolves to meet real-world development challenges and that we can quickly adapt to the complex needs of enterprise-scale development teams, from startups to Fortune 500 companies.

As we grew from open source to enterprise, we promised ourselves one thing: we wouldn’t lose sight of what got us here. We’re proud to say we’ve stayed true to our roots, listening to our community and building tools that make their lives easier. Whether it’s students taking their first steps into cloud development, seasoned engineers adding new features to an existing stack, or infrastructure teams running tests for infrastructure as code (IaC) in CI pipelines, LocalStack is there every step of the way.

What’s Next for LocalStack?

This Series A funding opens up new opportunities for expanding LocalStack’s capabilities and going beyond AWS.

Recent previews for Snowflake and our roadmap for an Azure emulator position us to support multi-cloud strategies - a critical focus for modern enterprises. Expanding beyond AWS will strengthen LocalStack’s role as the de-facto platform for local cloud development, and will enable new use cases like developing cross-cloud integrations, or testing cloud migrations where workloads get moved from one platform to another.

We’re also doubling down on advanced features around developer experience (DevX), team collaboration, and deep application insights. A big focus of our work is to enable use cases that are hard or impossible to achieve in the real cloud - for example, snapshotting and restoring the full state of a cloud app, or inspecting the messages of an event-based application and re-playing individual events for debugging, or simulating an outage of an entire cloud region to test application resilience.

We envision a world where developers can test application functionality, security, and resilience, play with chaos engineering, and prepare for every scenario—all within LocalStack. And as AI reshapes our industry, local development becomes even more critical. Imagine iterating on AI models without network latency, complete data privacy and security, full customization, and, why not, even more environmentally friendly. We’re committed to making cloud development not just more efficient but also a lot more fun.

Looking Ahead and Building the Future, Together

We extend our deepest gratitude to our customers, community, partners, and investors who have fueled our growth and momentum. Your trust and engagement inspire us every day to push the boundaries of what’s possible in cloud development.

And of course, huge kudos and congrats to our entire team at LocalStack! None of this would be possible without your dedication, commitment, and daily hard work - your passion for our mission and relentless drive are what turns our shared vision into a reality. Thank you all for making this journey possible!

In the end, this is about something bigger than code. We believe that by empowering developers to work faster and smarter, we’re helping build better products that can change the world. When developers can focus on what they do best - creating, innovating, and pushing boundaries - we all benefit.

We’re incredibly excited to continue this journey with you, our community. This Series A is more than just funding - it’s a reaffirmation of our mission to give developers back control of their cloud environment. And we’re only just getting started. So here’s to faster builds, quicker feedback, and a world where cloud development is no longer something you wait for but something you control. Let’s build the future together - one local environment at a time.

Thank you for being part of this journey. Here’s to building the future of cloud development - together.
