• •Tangled released Spindle, a system designed to run CI tasks within isolated microVMs.
• •The architecture leverages Firecracker microVMs to provide hardware-level isolation for untrusted code execution.
• •The current documentation lacks benchmarks comparing Spindle's performance overhead against traditional container-based CI solutions.

Tangled has launched Spindle, an infrastructure layer utilizing Firecracker microVMs to execute isolated CI pipelines. While traditional CI systems typically rely on Docker containers, this approach shifts toward hardware-backed virtualization to enhance security in multi-tenant environments. However, the performance impact of booting individual VMs for ephemeral tasks remains a primary hurdle for developers seeking low-latency execution. Adoption will likely hinge on whether the security benefits outweigh the increased resource overhead compared to standard containerized CI.
