AWS Compatible
Works with AWS CLI, SDK v2, and Terraform. Drop-in replacement — point your endpoint and go.
Docker Native Lambda
Lambda containers run in Docker with AWS Runtime Interface Emulator. Layers, extensions, and secrets cache built in.
Dashboard UI
Built-in web console to manage resources, view topology, inspect logs, and monitor event flows.
Event Driven
SQS and DynamoDB Streams event source mappings, SNS fanout to SQS and Lambda, and EventBridge scheduled or custom-event flows with Lambda targets.
Terraform Ready
200+ API actions implemented. Unknown actions return empty success responses so production .tf files just work.
