LocalStack

Run fully functional cloud applications on your local infrastructure. Get instant feedback, debug interactively, and reduce costs from idle cloud environments.

Eliminate the complexity and delays of traditional cloud development by replicating fully functional cloud applications on your local infrastructure. This allows you to build, test, and debug freely, with the same production behavior, but with a much faster feedback loop and full control over your environment.

It provides a high-fidelity emulation of cloud services, so you can build with confidence and avoid surprises when you deploy. Key benefits include:

  • Faster Dev & Test Cycles: Deploy and test full application stacks instantly on your machine. Hot reload functions, step through your code, and debug interactively without waiting on remote infrastructure.
  • Reduced Cloud Costs: Prevent wasted spending on idle and under-utilized non-production environments by empowering developers to build and test safely on local infrastructure.
  • Developer Autonomy: Eliminate access delays and conflicts over shared development environments. Every developer can build on-demand with a dedicated local environment.
  • Realistic Emulation: Build against real APIs with support for over 100 AWS services and Snowflake features, ensuring your application behaves as expected in production.
