Apache-2.0 license; v1.16.0 (Jun 4 2026); powers AWS Lambda and Fargate
Adoption
5 high confidenceUnderpins AWS Lambda and AWS Fargate, among the highest-volume serverless platforms in the world (trillions of invocations), plus downstream use in Kata Containers, Flintlock, and E2B. Production reach far exceeds >10M end-equivalent. (34.8k stars corroborate only.)

developed at AWS; powers AWS Lambda and AWS Fargate; integrated into Kata Containers and Flintlock
Capability
5 high confidenceFrontier-definer for the deployment category: hardware-VM isolation at container-like speed/density, the reference microVM that the managed sandbox layer (E2B, others) builds on. Defines the strongest point on the isolation x cold-start x scale matrix.
