It's a split decision.
Choose LocalStack if you need a local AWS, Snowflake, or preview-stage Azure environment for application development and testing. Its Hobby plan is free for non-commercial use; paid Base starts at $39 per license monthly billed annually ($45 monthly). Choose OpenStack if you need software to manage compute, storage, and networking infrastructure across on-premises, public-cloud, or edge deployments. The core is free to download and self-host, but operating costs and published pricing are unavailable. They’re different tools, not direct substitutes.

02Pricing compared
LocalStack has a free Hobby plan for hobbyists and non-commercial use, with 30+ emulated services, one personal sandbox and CI test support. For commercial teams, Base is $39 per license/month billed annually or $45 monthly. It includes 55+ services and 300 MB of lifetime workspace storage. Ultimate is $89 per license/month billed annually, with 110+ services and 3 GB of lifetime storage; its monthly AWS Marketplace price is not published. Enterprise pricing is not published, and AI agent usage is priced separately.
OpenStack’s core software is free to download and self-host. No monthly or annual price is published, and the available pricing information does not specify operating costs. So “free” describes the software, not a documented total cost to run it. Compare LocalStack’s per-license subscription with OpenStack’s unpriced self-hosted operation, not as equivalent plans.
03Features and depth
LocalStack simulates cloud services in a container on your infrastructure so developers and AI agents can develop, test and debug applications without provisioning cloud resources. The homepage lists 120+ AWS services, Snowflake emulation and Azure support in public preview. Plan limits differ: Hobby includes 30+ services, Base 55+ and Ultimate 110+. Ultimate also lists advanced IAM policy testing and a live AWS resource replicator. LocalStack describes failure review and validation of code fixes as part of its development workflow.
OpenStack manages infrastructure rather than emulating a cloud for application tests. Its components control pools of compute, storage and networking resources through APIs or a dashboard. Additional components provide orchestration, and deployments can be on-premises, in public clouds or at the edge. That makes the products different categories: LocalStack offers a local development environment; OpenStack is software for managing cloud infrastructure. Pick based on the job, not feature-count comparisons.
04Ease of use and learning curve
LocalStack is the narrower starting point if the goal is to test applications against simulated cloud services. It runs in a container, and the Hobby plan lists a VS Code integration and CI test support. Paid plans add more services and workspace capacity, but the limits still matter when choosing a tier.
OpenStack’s scope is broader: it manages compute, storage and networking across deployment settings. Its documentation describes infrastructure control through APIs or a dashboard, but the published information does not establish setup effort or administration requirements. We would not treat free self-hosting as a low-maintenance option. Choose LocalStack for application development and testing; choose OpenStack when you need to manage infrastructure resources.
Questions people ask
Is LocalStack a replacement for OpenStack?
No. LocalStack emulates cloud services for application development and testing. OpenStack manages compute, storage and networking infrastructure. They address different jobs, so neither is a direct replacement for the other. Choose based on whether you need a local testing environment or infrastructure management.
Is LocalStack free for commercial use?
The free Hobby plan is listed for hobbyists and non-commercial use. Commercial teams can choose Base, listed at $39 per license/month billed annually or $45 monthly. The pricing page also lists Ultimate at $89 per license/month billed annually; its monthly AWS Marketplace price is not published.
Does OpenStack have a monthly price?
No monthly or annual price is published for OpenStack’s core software. It is free to download and self-host, but the published pricing information does not state the cost of operating a deployment. Treat free software and total cost of running infrastructure as separate questions.
Which should I choose for AWS development?
Choose LocalStack if you want to develop or test applications against emulated AWS services without provisioning cloud resources; its listed service count varies by plan. OpenStack is for managing infrastructure resources such as compute, storage and networking, not for AWS service emulation.
