    Use Cases & Benefits

    • Emulates AWS cloud services locally using Docker and native binaries without requiring an AWS account or auth tokens.
    • Provides a lightweight, fast-starting, and fully open-source alternative to LocalStack with broad AWS service coverage and real Docker-backed execution.
    • Use for local development and testing of AWS applications without incurring cloud costs or needing AWS credentials.
    • Use for continuous integration pipelines that require fast, reliable AWS service emulation with low resource consumption.
    • Use for migrating from LocalStack to a no-strings-attached AWS emulator that supports real Docker containers for complex services like Lambda and RDS.

    From the README

    Light, fluffy, and always free

    No account. No auth token. No feature gates. Just docker compose up.

    Floci is a free, open-source local AWS emulator for development, testing, and CI.

    It gives you AWS-shaped services on your machine without requiring a cloud account, an auth token, or paid feature gates. Point your AWS SDK, CLI, Terraform, CDK, OpenTofu, or test suite at http://localhost:4566 and keep your existing workflows.

    Already using LocalStack? Floci is a drop-in replacement: swap the image and keep going. See Migrating from LocalStack.

    Floci is the AWS member of the Floci emulator family, named after floccus, the cloud formation that looks like popcorn.

    The fastest way to run Floci is with the official CLI

    No Docker? Each release also ships a standalone floci-aws binary for Linux, macOS and Windows; see Native binary.
