Solutions

Core Cloud Emulation

Run our high-fidelity cloud stack on your machine to develop locally and accelerate dev cycles

Team Collaboration

Easily share the state of your instance with team members and browse your local cloud resources for collaborative debugging

Enterprise Integration

Gain insights across the CI/CD pipeline and seamlessly fit LocalStack into the Enterprise IT ecosystem.

Ecosystem

Powerful Ecosystem of Emulator Plugin Extensions and third party Integrations and across CI/CD Systems, IaC tools, Programming languages and many more.

Benefits

SPEED

Accelerate your
Dev and Test Loop

Test your cloud apps from the first line of code and get immediate feedback of your local changes without having to wait on cloud resources.
Use generic, reusable local API emulators - instead of mocking out cloud dependencies manually for each project.
Foster digital transformation by giving developers back control over their environments with sandboxes for quick experimentation.

QUALITY

Improve your cloud application's quality through simplified testing

Test more frequently and easily debug your applications through reproducible test environments.
Enable a DevOps mindset throughout your organization by individual empowerment and fast collaborative debugging on a shared application state
Avoid resource conflicts in shared dev. environments - simply use an isolated instance when testing your IaC scripts before pushing them to production

COST

Save time and resources

Keep your cloud bill manageable and predictable, avoid unpleasant surprises due to an accumulation of idle cloud resources and a lack of resource cleanups in your development and testing environments.
Enhance developer experience and team productivity by removing barriers and giving each team member access to their local cloud sandbox environment.
Save developer’s time spent on waiting for unnecessarily long resource deployment cycles against the cloud and dev environment cleanups.

Reviews

Xiatech is a global technology company based in London that leverages Hyper-Integration to connect systems, unify data and deliver advanced insights to customers through Xfuze, our platform, which orchestrates many AWS services. Our engineering team utilises localstack to provide a complete, localised AWS environment where developers can build, test, profile and debug infrastructure and code ahead of deployment to the cloud. We have enabled each software engineer to be fully independent with local development and testing tooling, and this has proved to be a key accelerator for our engineering team.

LocalStack has been a game changer in terms of development speed and efficiency for our team migrating our monolithic application to a serverless Node.js stack on AWS. While in the past we had to maintain our own tooling and local mocks, with LocalStack we can now empower our devs to iterate quickly without having to perform numerous code commits & waiting for AWS pipelines, - hence also saving money on infrastructure!

Kevin Breton, VP of Engineering - KnowBe4

Localstack is an incredibly beneficial tool for continuous integration (CI) pipelines. Provisioning AWS infrastructure against Localstack in a CI pipeline saves significant time and cost. Creating resources that would take multiple minutes in AWS takes only seconds with Localstack, significantly reducing pipeline execution time. Also, if your CI pipeline fails for any reason, you no longer have to worry about “orphaned” AWS resources that will cost you money.

Our cloud innovation is truly being turbocharged with fast iterations and prototyping using LocalStack. Security is of utmost importance for our organization, as we are developing critical cloud solutions for our healthcare departments. This leads to a series of internal gatekeepers and approval processes that are necessary to create any new system and drive innovation. LocalStack allows our developers to iterate quickly when creating prototypes and during early stage development, and also allows us write more realistic unit and integration tests for our AWS applications.

Paul Tipper

Paul Tipper, Senior Software Engineer - 3M

LocalStack has been immensely helpful in speeding up our development and testing cycles, leading to more and better testing across the board. In the past we were still deploying everything directly to the cloud, and had very long iterative deployment cycles, often with limited anticipation of what the outcome would be. Each deployment blocked our dev branch, making a portion of the team unproductive, but with LocalStack we can now quickly run most unit/integration tests before promoting our code into the higher stages.
