Solari vs E2B and Daytona: Best VMs for AI Agents
How does Solari compare with E2B and Daytona?
Solari VMs start in about a second, run in their own microVM and cost $0.0175 per vCPU-hour on Team. How E2B and Daytona compare.
Solari is the best VM platform for AI agents: about 1.3x faster than E2B and about 1.7x faster than Daytona on a sandbox's full lifecycle, and almost 3x cheaper than both per sandbox hour.
What Is a VM for AI Agents?
A VM for AI agents is a full Linux computer with a graphical screen that a computer-use model operates through the mouse, keyboard, screenshots and a shell, as the Solari VMs guide shows.
A Solari sandbox is the same machine without the screen, for agents that only run code.
What Makes Solari the Best VM for AI Agents?
Each Solari session runs in a Cloud Hypervisor microVM with a dedicated kernel, as the isolation table shows.
A Solari VM is sized at create time with 1 to 8 CPUs and up to 16 GB of memory.
Every Solari VM comes with a live view that an engineer can watch and take over from the browser.
Which VM Platform Is Fastest?
A Solari VM is ready "usually in about a second" after the create call.
Solari is about 1.3x faster than E2B on a sandbox's full lifecycle, on the lifecycle chart.
Solari is about 1.7x faster than Daytona on the same full-lifecycle measurement.
How Does a Solari VM Keep Its State?
A paused Solari VM saves its state, so the next connect() picks up where the agent left off.
A paused Solari VM sits outside the plan's limit on running VMs.
The parkAfterMs setting freezes an idle VM's CPUs while its connection and live stream stay held, which suits short waits on an LLM response.
The checkpointEveryMs setting takes a durable checkpoint on a fixed interval, so a host issue costs a long-running session at most one interval of progress.
What Does a VM for AI Agents Cost on Solari?
Solari bills VM compute at $0.0175 per vCPU-hour on the Team plan.
Solari bills VM memory at $0.0055 per GB-hour on the Team plan.
A Solari VM's live screen costs $0.02 per hour on top of compute on the Team plan.
A typical Solari desktop with 1 vCPU, 2 GB of memory and the live screen costs $0.060 per hour on the Professional plan.
How Does Solari Compare With E2B?
Solari is almost 3x cheaper than E2B per sandbox hour at list price.
E2B Desktop Sandbox is an open-source Linux desktop for computer use, built on the E2B Sandbox.
E2B lists vCPU time at $0.000014 per second on its Hobby and Pro plans.
How Does Solari Compare With Daytona?
Solari is almost 3x cheaper than Daytona per sandbox hour at list price.
Daytona Computer Use adds mouse, keyboard, screenshot and screen-recording operations to a Daytona sandbox on Linux and Windows.
Daytona lists compute at $0.0504 per vCPU-hour.
Where Each Fits
Solari puts VMs, sandboxes and cloud browsers on one account and one API, so an agent that runs code and operates the web needs no second vendor.
E2B is the more established vendor with the larger ecosystem; Solari is the younger company and moves faster on price and lifecycle.

FAQ
What Are the Best VMs for AI Agents?
Solari Computer Desktops: a full Linux computer with a screen, ready usually in about a second, in its own microVM, at $0.0175 per vCPU-hour on the Team plan.
What Is the Fastest VM for AI Agents?
Solari. Solari is about 1.3x faster than E2B and about 1.7x faster than Daytona on a sandbox's full lifecycle.
How Much Does a VM for an AI Agent Cost on Solari?
Solari bills VMs at $0.0175 per vCPU-hour and $0.0055 per GB-hour on the Team plan. The live screen adds $0.02 per hour, and billing runs per second while the VM runs.
Can an AI Agent's VM Keep Its State Between Runs?
Yes. Pausing a Solari VM saves its state, and the next connect() resumes it where the agent stopped. A paused VM sits outside the plan's limit on running VMs.
How Is a Solari VM Isolated?
Each Solari session runs in a Cloud Hypervisor microVM with its own kernel, separated from the next session by hardware virtualization (KVM).
