Your pipeline shouldn't have to rent the cloud just to test the cloud
Cloud-hosted CI/CD test stages add cost and delay to every build. Three structural problems slow and inflate them:
Every build waits on the cloud to do work it was never built for
Tests need to behave like the cloud. That doesn't mean every test needs to wait for one. Spin up, deploy, seed, run, tear down: a single test can take 30 to 45 minutes before anyone sees a result.
Shared state and network variability make tests you can't trust
When jobs share cloud infrastructure, one run contaminates another, and network variability produces failures that have nothing to do with the code. Engineers lose hours re-running builds just to separate real failures from noise.
The more you build, the higher the bill, and the bigger the attack surface
As AI-generated code drives more builds, non-production cloud spend and pipeline time scale. Every job with cloud access widens the pipeline's attack surface.
Local sandboxes. Faster validation. Seamless deployment.
LocalStack replaces slow, unreliable, expensive live-cloud test stages with a local sandbox per job. Each one spins up in minutes, runs the same way every time, and costs nothing per build: cloud-quality sandboxes, isolated from the cloud.
A cloud sandbox for every pipeline
Production-grade cloud behavior on your CI runner, available on demand. No provisioning queues, no shared staging, no cloud credentials. Each job gets its own disposable sandbox that simulates your production app.
Faster runs, repeatable results, free parallelism
Tests run against production-grade APIs in seconds, in parallel across jobs, with no shared-state contamination. Every run produces the same result, so a green build means green.
Deploy to production with no code changes
Code validated in the local sandbox runs in production unchanged. No rewrites, no special builds, no deployment friction.
Faster builds, lower bills, results you can trust
A disposable, production-grade sandbox per job instead of the live cloud.
Zero cost per run
Integration and cloud-dependent test stages come off the cloud bill entirely. Run them as often as you like without adding a cent of non-production cloud spend.

Faster pipelines
Sandboxes spin up in minutes. Load a Cloud Pod to start from a preconfigured environment instead of rebuilding it from IaC.
Repeatable, trustworthy results
Each job runs in its own disposable sandbox, so shared-state contamination and network variability disappear.
Unlimited parallel runs
Run as many jobs in parallel as you need. Sandboxes never collide and never hit cloud rate limits or accumulate cost.
Reduced attack surface
No cloud credentials in CI means no access-management overhead and no blast radius.
Production-grade fidelity
LocalStack runs the same APIs your cloud provider does, so what passes in the pipeline behaves the same in production.
Spin up per job. Test in parallel. Ship with confidence.
LocalStack drops into your existing pipeline as a service. Each job gets its own production-grade cloud sandbox, runs its tests, and tears down clean, with no live cloud, no shared staging, and no credentials.
Step 1
Spin up
Each CI job starts a fresh sandbox from the code and IaC already in your repo, or from a Cloud Pod: a snapshot of your full environment with services and data preconfigured to a known state. Cloud Pods load far faster than running the IaC.
Step 2
Test in parallel
Integration and cloud-dependent tests run against production-grade cloud APIs across every job at once, with repeatable results, full logs, and traces.
Step 3
Tear down
Sandboxes are disposable. Every job resets to a clean state, so no run ever contaminates another. Shared-state failures disappear.
Step 4
Ship
Code validated in the sandbox runs in production unchanged.
Built for AI-scale build volume
As AI-generated code drives up build volume, test stages stay off the cloud bill, keeping cost and pipeline time in check.

Works in your pipeline
Run a complete cloud sandbox per CI job in GitHub Actions, GitLab CI, Jenkins, CircleCI, and more: parallelizable, disposable, and repeatable.
Everything a pipeline needs to test the cloud, locally
LocalStack gives your pipeline the isolation, repeatability, and state control that make cloud-dependent tests fast and trustworthy in CI.
Multi-cloud coverage
Run production-grade AWS and Snowflake services on your CI runner, and point your tests at a single local endpoint.
IaC testing
Deploy and test the same Infrastructure as Code you ship to production, and catch misconfigurations before they reach the cloud.
Isolated, disposable sandboxes
One clean sandbox per job, torn down after each run. No shared state, no cross-build contamination, no manual cleanup.
State Management
Snapshot the full state of a sandbox with Cloud Pods, replay, and reuse across jobs to reproduce a failing build on demand.
Chaos Engineering
Inject faults and outages into pipeline tests to check how your app behaves under failure, safely, on infrastructure you can actually break.
Built for every developer, AI agent, and pipeline.
Every build passes through the same pipeline, but each owner wants different things. LocalStack delivers for every scenario.
DevOps & platform engineers
Give every pipeline a local cloud sandbox that fits your existing runners and golden paths: same code, same IaC, no per-job cloud accounts to provision or govern.
Engineering & FinOps leaders
Take non-production tests off the cloud bill while lifting the DevOps Research and Assessment (DORA) metrics tied to business outcomes: higher deployment frequency and shorter lead time for changes.
AI-native teams
Test all AI-generated code your team ships, without growing your cloud cost or risk.

Frequently asked questions
A local cloud sandbox for CI/CD is an isolated environment that simulates cloud services, like AWS, on your CI runner instead of live cloud infrastructure. Each pipeline job deploys and runs integration and cloud-dependent tests against production-grade APIs, with no provisioning delay, no per-run cloud cost, and no cloud credentials.
LocalStack removes the cloud overhead from every build. Tests run against a local sandbox that spins up in minutes, so there's no provisioning wait and no per-second cloud charge for the run. Because sandboxes are disposable and isolated per job, builds run in parallel without contention, and savings grow with every build.
Yes. LocalStack runs as a container or CLI service inside GitHub Actions, GitLab CI, Jenkins, CircleCI, and other runners. Jobs point their existing tests at the local endpoint. No rewrite required.
No. Jobs run against the local sandbox without cloud access, which shrinks the pipeline's attack surface and removes the access-management overhead of giving automated workflows cloud permissions.
Yes. LocalStack runs the same APIs your cloud provider does, so code validated in the local sandbox deploys to production with no code changes.
No. Mocks are static; LocalStack runs the real APIs against local implementations, with production-grade behavior for testing, debugging, and validation.
Spin up a complete cloud sandbox per pipeline. Pay nothing per run.
Cloud-native development without the overhead, costs, or risk of the cloud. A cloud-quality sandbox for every developer, AI agent, and pipeline.
