It's a split decision.
LocalStack and OpenStack solve different problems. Choose LocalStack to develop and test software against simulated AWS, Snowflake or preview Azure services without provisioning cloud resources. Its local container fits into a development and CI workflow. Choose OpenStack to build and manage cloud infrastructure: compute, storage and networking, operated on-premises, in public clouds or at the edge. OpenStack’s core software is open source and free to download; your team owns deployment and operations. They can complement each other, but they are not interchangeable.

| Open source and licence | Open-source status and licence are not stated | Open-source software; licence name not specified |
| Self-hosting | Runs in a container on your infrastructure | Self-host on-premises, in public clouds or at the edge |
| Integrations | Names AWS, Snowflake, Azure, CDK, Terraform and Pulumi | Integrates with open-source tools; examples are not named |
| Deployment model | Local cloud simulation for development and testing | Cloud infrastructure control plane for compute, storage and networking |
| Platforms | Web | Web |

02Pricing at real usage
LocalStack’s Hobby plan is free and includes 30+ emulated services, one personal sandbox, CI test runs and VS Code integration. Base costs $39 per license per month billed annually or $45 monthly. It includes 55+ services and 100 preview minutes per workspace per month. Ultimate is $89 per license per month billed annually, with 110+ services and 500 preview minutes per workspace per month. Its monthly Ultimate price through AWS Marketplace is not published. Enterprise pricing is also not published; AI agent usage is priced separately through sales.
OpenStack’s core software is free to download and self-host. The project publishes no monthly or annual software price. That does not make an OpenStack deployment cost-free: your organization must account for infrastructure and the work of deploying and operating it. Those costs depend on your environment and are not a published OpenStack plan price.
03API, SDKs and integration
LocalStack fits into a development workflow as a containerized cloud emulator. Its homepage names AWS and Snowflake, with Azure in public preview, and lists integrations with CDK, Terraform and Pulumi. LocalStack provides documentation for its AWS, Snowflake and Azure emulators. The homepage also names VS Code integration on the free Hobby plan. The vendor doesn't publish a named SDK or language matrix on its homepage, so check the relevant emulator docs before choosing a client library or test setup.
OpenStack is an infrastructure control plane managed through APIs or a dashboard. Its components provide compute, storage and networking services, with additional components for orchestration and other infrastructure functions. The OpenStack homepage describes integration with open-source tools and platforms but does not name them. It does not name a CLI, SDK or language matrix on the homepage. Start by selecting the OpenStack components your deployment needs, then verify the APIs and tooling supported by your chosen distribution or cloud provider.
04Open source, self-hosting and lock-in
OpenStack is open-source software that teams can download and self-host. Its deployment options include on-premises infrastructure, public clouds and edge environments. The homepage does not name the software licence, so confirm its terms before redistributing or modifying a deployment. OpenStack also has a marketplace of public-cloud providers, which offers another route besides operating the control plane yourself.
LocalStack runs a simulated cloud environment in a container on your infrastructure, but its open-source status and licence are not stated on the homepage. Its paid plans add features and workspace storage; Ultimate lists a live AWS resource replicator. Neither product’s homepage describes a general data-export format or migration path. Before adopting either, ask how to export state and test how much of your application depends on product-specific behavior. LocalStack emulates services; OpenStack manages infrastructure, so moving between them is not a like-for-like migration.
Questions people ask
Can LocalStack replace OpenStack?
No. LocalStack simulates cloud services for local development and testing. OpenStack manages infrastructure resources, including compute, storage and networking. Use LocalStack to test application behavior against emulated services; use OpenStack when you need to provision and operate cloud infrastructure.
Is LocalStack free to use?
LocalStack lists a free Hobby plan for non-commercial use, including 30+ emulated services, one personal sandbox and CI test runs. Paid Base starts at $39 per license per month when billed annually, or $45 monthly. Ultimate is $89 annually per license; its monthly AWS Marketplace price is not published.
Is OpenStack free and open source?
OpenStack is open-source software, and its core software is free to download and self-host. The OpenStack homepage does not name the software licence, so verify the applicable terms before redistribution or modification. Infrastructure and operating costs depend on how and where you deploy it.
Can I run LocalStack and OpenStack together?
They have different roles, so a team could use LocalStack for local application tests and OpenStack to manage infrastructure. LocalStack emulates cloud services in a container; OpenStack controls compute, storage and networking. The vendor pages do not describe a specific integration between the two.
