Floci has introduced a new tool designed to emulate services from major cloud providers including AWS, Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI) directly on a local machine. This allows developers to build, run, and verify cloud-native applications without requiring active cloud accounts or credentials.
The emulators are provided as standalone, MIT-licensed binaries. This approach removes the need for authentication tokens, feature gates, or any cloud account setup, simplifying the development workflow.
The local emulation environment aims to accelerate development cycles, particularly for AI agents that generate cloud code. By providing an instant, credential-free local cloud, Floci allows agents to test code rapidly and safely without interacting with live cloud environments. This prevents potential exfiltration of real cloud secrets and avoids unexpected billing.
The emulators boast fast cold start times (24 ms) and low idle memory consumption (13 MiB), facilitating quick spin-up, testing, and tear-down within the development loop.
Floci positions itself as a drop-in replacement for LocalStack, utilizing the same port 4566 and supporting 119 services, allowing for a switch with zero code changes. It covers a range of services, including Blob, Queue, Table, Functions, and Event Hubs for Azure; GCS, Pub/Sub, Firestore, and Cloud Run for GCP; and Object Storage, Identity, and Queue for OCI.
The tool is compatible with existing SDKs, CLIs, Terraform/OpenTofu modules, and test runners. A unified command-line interface and visual dashboard are available for managing and inspecting all Floci emulators.
Floci emphasizes an open model with no pricing tiers, gatekeeping, or enterprise feature flags. All services are available to every developer. The tool can be used by pulling a Docker image, and it does not require sign-ups, API keys, or telemetry. This contrasts with other local cloud emulation tools that may introduce authentication requirements.
