Morph vs AWS Lambda MicroVMs: branching VMs against AWS microVMs

Morph bills VMs in MCUs; Lambda MicroVMs bill a Firecracker baseline. The 2 vCPU, 4 GB benchmark is $1.67 on Morph and $4.20 on Lambda.

Runtime is 62% cheaper than Morph and 85% cheaper than Lambda MicroVMs on that benchmark, 1,000 runs of a minute on 2 vCPU and 4 GiB with 20 CPU-seconds of work each. Morph's MCU pricing keeps it well under Lambda; Runtime's measured CPU keeps it under both.

At a glance

	Morph	AWS Lambda MicroVMs	Runtime
Isolation	Full virtual machines	Firecracker microVM	Firecracker microVM, own kernel
Price	$0.05 per MCU-hour: 1 vCPU, 4 GB or 16 GB of disk	$0.2522 an hour for 2 vCPUs and 4 GB	Measured CPU and reserved memory
Branching	Infinibranch: a running VM to hundreds of replicas	None	Forks: a running sandbox to up to 10 copies
Lifetime	Devboxes scale to zero and keep memory	State kept up to 8 hours	Pauses kept 1 to 365 days
Plan	Free with no credit; Developer $40, Team $250 a month	None	None; prepaid credit from $10

Branching is the difference

Morph's reason to exist is branching a live machine, memory included, into many copies, for agents that search several paths from one state. Lambda MicroVMs have nothing like it; each MicroVM starts from its image or its own snapshot. Runtime forks a running sandbox into up to ten copies with memory and processes.

Cost for the same job

2 vCPU and 4 GB (2 MCUs on Morph), 60 seconds, 20 CPU-seconds, 1,000 runs:

With both CPUs busy for the whole minute, the totals are $1.67 on Morph, $4.20 on Lambda and $1.33 on Runtime.

Which one to pick

• Morph for search over many branches of one running machine.
• Lambda MicroVMs for AWS-native sandboxes.
• Runtime for the lowest price per run, with forks when a few branches are enough.
