SST (Serverless Stack) provides the best developer experience for building full-stack apps on AWS. Live Lambda development, Ion v3 with Pulumi, and multi-cloud support.
Reviewer scorecard
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“The best way to use AWS. Live Lambda debugging, simple configuration, and the migration to Ion (Pulumi-based) is smart.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“Makes AWS approachable for full-stack developers. The DX gap between SST and raw CDK is enormous.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
“SST proves AWS can have great DX. Ion's Pulumi-based multi-cloud approach positions it for the future.”
