LocalStack replicates fully functional cloud applications on local infrastructure so you can build freely without the complexity and delays of traditional cloud development.

LocalStack eliminates the complexity of developing on the cloud so your teams can ship to the cloud faster and more efficiently.
Free up DevOps resources & democratize access for developers with local dev & test environments on safe, local infrastructure.
Eliminate access delays and conflicts over shared development environments. Empower every developer to build on-demand with local environments for mission-critical dev and test cycles.
Prevent wasted cloud costs from idle and under-utilized non-production environments while empowering your developers to build freely and safely on local infrastructure.
Deploy and test full stacks instantly, right on your machine. Hot reload functions, step through your code, and debug interactively–without waiting on remote infrastructure to catch up.




Emulate cloud services locally with high fidelity. Build fast. Test safely. No surprises.
