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
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“The best way to use AWS. Live Lambda debugging, simple configuration, and the migration to Ion (Pulumi-based) is smart.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“Makes AWS approachable for full-stack developers. The DX gap between SST and raw CDK is enormous.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
“SST proves AWS can have great DX. Ion's Pulumi-based multi-cloud approach positions it for the future.”
