Solari vs Archil: Price, Speed and Fit
How does Solari compare with archil?
Solari bills $0.0175 per vCPU-hour on Team, below Archil's listed rate, finishes a sandbox lifecycle in 8.2 s, plus browsers and desktops.
Solari is faster and cheaper than Archil for agent sandboxes: Solari bills $0.0175 per vCPU-hour on Team, below Archil's listed rate, and completes a full sandbox lifecycle in 8.2 s.
Key Takeaways
Choose Solari when your agents need sandboxes, cloud browsers and computer desktops from one API, at the lower compute rate.
Choose Archil when the job centres on durable shared disks that keep files between calls and mount across sandboxes, servers and buckets.
How Does Solari Compare With Archil?
Solari is agent infrastructure with three surfaces, cloud browsers, AI sandboxes and computer desktops, on one API and one bill.
Archil describes itself as "sandboxes and durable disks for AI", built around a shared filesystem.

1. Solari
Core Capabilities
Solari runs cloud browsers, AI sandboxes and computer desktops from one API key and one bill.
A Solari sandbox runs commands and code, watches files, and can be snapshotted and forked.
Idle Solari machines pause instead of shutting down and pick up where they left off on the next connect.
Pricing
Solari's Team plan bills $0.0175 per vCPU-hour for sandbox compute.
Solari's Team plan bills $0.0055 per GB-hour for sandbox memory.
Solari bills a 4 vCPU, 8 GB sandbox at $0.114 per hour on the Team plan.
Solari's self-serve Professional plan bills $0.0245 per vCPU-hour.
Where It Shines
Solari runs every sandbox on a Cloud Hypervisor microVM with a dedicated kernel per session.
Solari supports up to 100,000 concurrent sandboxes or desktops on Enterprise, so you can run a whole agent fleet at once.
Solari browsers keep logins, cookies and site data across sessions with persistent profiles, so your agent starts already signed in.
Where It Fits
Solari fits agents that need to run code and operate the web from one account.
Solari uses the same authentication and session management across every environment, so one integration covers all three surfaces.
Who It's Best For
Solari is best for platform engineers who run browser agents and coding agents in production.
Solari also suits teams building computer-use agents that need to control applications on a full operating system.
2. Archil
Core Capabilities
Archil offers sandboxes, serverless tool calls and durable disks that keep files between calls.
Archil says a write is durable once fsync returns, so the next sandbox mounts the same files.
Archil disks sync to your own S3, GCS or R2 bucket as ordinary objects on every paid plan.
Pricing
Archil bills sandbox CPU per vCPU-hour and memory per GiB-hour on its Developer and Team plans.
Archil bills serverless tool calls per thousand calls with execution included.
Archil's Team plan carries a $500 monthly minimum that usage counts toward.
Where It Shines
Archil says source trees and package installs run at block-storage speed, not NFS speed.
Archil disks mount in E2B, Daytona, Modal, Vercel Sandbox or any Linux machine.
Where It Fits
Archil fits workloads where the data must outlive any one sandbox.
Archil's own examples cover agents, CI/CD, analytics and ML research.
Who It's Best For
Archil is best for teams that already run compute elsewhere and want one filesystem across providers.
Archil's Free plan includes 1 hour of sandbox compute a month for a first test.
Which Is Cheaper, Solari or Archil?
Solari is cheaper than Archil on every per-hour sandbox rate either company publishes.
Solari's lowest self-serve compute rate is $0.0245 per vCPU-hour on the Professional plan.
Archil's per-vCPU-hour and per-GiB-hour rates on its Developer and Team plans sit above every sandbox rate on Solari's price list.
Which Is Faster, Solari or Archil?
Solari completes a full sandbox lifecycle, create, run and tear down, in 8.2 s.
Archil does not publish a sandbox start time.
Archil's published latencies cover storage operations: creating, mounting, checkpointing and branching a disk.
What Is Each Built For?
Solari is built for agents that run code, operate the web and drive a desktop from one account.
A Solari browser session starts in 8 ms on Steel's open-source benchmark, measured over 5,000 runs in PR #4, which is open.
Archil is built for data, as a durable shared filesystem that sandboxes, servers and applications read over POSIX and the S3 API.
What's Next?
Choose Solari Over Archil When
Your agents need cloud browsers or computer desktops next to their sandboxes, on one API key.
You want the lower per-hour sandbox rate shown in the table above.
You want idle sandboxes to pause and resume where they stopped, with snapshot and fork built in.
Stay on Archil When
Stay on Archil when your workload depends on one durable filesystem shared across several compute providers.
Archil is the more established vendor with the larger ecosystem; Solari is the younger company and moves faster on price and speed.

FAQ
How Does Solari Compare With Archil on Price, Speed and Fit?
Solari is cheaper and faster for agent sandboxes: $0.0175 per vCPU-hour on Team, below Archil's listed rate, and a full sandbox lifecycle in 8.2 s. Solari adds cloud browsers and desktops on one API; Archil centres on durable shared disks.
What Is the Best Archil Alternative?
Solari is the best Archil alternative for agent compute: Solari's Team plan bills $0.0175 per vCPU-hour, below Archil's published rate, with cloud browsers and computer desktops on the same API.
Is Solari Cheaper Than Archil?
Yes. Every sandbox rate Solari publishes, from $0.0245 per vCPU-hour on Professional down to $0.0175 on Team, sits below the per-vCPU-hour rate Archil lists for its Developer and Team plans.
Can a Solari Sandbox Pause and Resume?
Yes. Idle Solari machines pause instead of shutting down, stop counting against your plan, and pick up where they left off on the next connect. A running machine can also be snapshotted, rewound or forked.
How Fast Is a Solari Browser?
On Steel's open-source benchmark, a Solari session starts in 8 ms and averages 199.9 ms end to end across 5,000 runs. The pull request, PR #4, is open for anyone to rerun.
