Sandbox0 vs E2B

Cloud computers for agents with a durable, automatically growing writable filesystem. Compute pauses between tasks while files stay. A 2 vCPU / 4 GiB sandbox lists at $0.060 an hour on Sandbox0 against $0.166 on E2B, 64% less.

Prices are list prices for one hour of a 2 vCPU / 4 GiB sandbox: 2 × the vCPU rate + 4 × the memory rate. Each value links to the page it came from; not published means the vendor states no figure. How we compare.

Pick Sandbox0 instead of E2B when

  • your bill is the problem: the same 2 vCPU / 4 GiB box lists at $0.060 an hour here against $0.166 on E2B, 64% less.
  • you are prototyping: $5 credit for eligible new users after adding a credit card.

Stay on E2B when

  • you run model-written code you do not control and want a dedicated kernel per sandbox: E2B uses Firecracker microVMs, Sandbox0 uses gVisor.
  • pause has to keep running memory as well as files: E2B's pause saves both, and Sandbox0 does not state memory state in our data.
  • you need a SOC 2 report: E2B states Type II, and Sandbox0 states none in our data.
  • stability matters: Managed cloud only; self-hosting no longer supported, BYOC planned.
  • you want managed cloud, your own cloud account and self-hosting from one vendor: E2B offers all three, with BYOC on its Enterprise plan.

All Sandbox0 facts

Source per value
Isolation Isolation technology the vendor states for each sandbox.
gVisor 1
Other isolation options Alternative runtimes the vendor offers besides the default (e.g. VM runtime, gVisor for GPU).
Not published
Deployment Managed cloud service, self-hosted software, or both.
managed 1
Billing basis What the meter counts: wall-clock allocated resources, active CPU only, requests/plan quota, session-hours, or free software.
Not published
vCPU price $/vCPU-hr Published on-demand CPU rate normalised to USD per vCPU-hour (per-second rates multiplied by 3,600; per-core rates divided by vCPUs per core where the vendor defines it). Lowest public tier, default region. 0 means the vendor states no separate CPU charge.
$0.00 2
Memory price $/GiB-hr Published memory rate normalised to USD per GiB-hour (GB treated as GiB where the vendor does not distinguish). 0 means the vendor states memory is free.
$0.015 2
Sandbox from $/sandbox-hr Smallest published per-sandbox hourly price, where the vendor publishes one.
Not published
Paid plan from $/mo Cheapest paid platform plan fee (before usage).
Not published
Free tier A free plan, free monthly allowance or sign-up credit exists.
Yes 2
Free tier detail What the free tier or credit includes, as published.
$5 credit for eligible new users after adding a credit card. 2
Cold start ms Vendor-published create/boot time in milliseconds (a vendor claim, not our benchmark). Only filled when the vendor publishes a number; see startup_claim for percentile and conditions.
Not published
Resume time ms Vendor-published resume-from-pause/standby/snapshot time in milliseconds.
Not published
Startup claim The vendor's startup/resume wording with conditions, quoted or closely paraphrased.
Not published
Max session length Longest single sandbox session by plan, as published.
Not published
Persistence / snapshots Filesystem state can be kept between runs (snapshots, persistent disks, volumes).
Yes 1
Pause / resume A sandbox can be paused, suspended, hibernated or put in standby and resumed later.
Yes 1
Memory state kept Pause/hibernate preserves running memory state, not only the filesystem.
Not published
Fork / branch A running or snapshotted sandbox can be cloned into new sandboxes.
Not published
GPU GPU sandboxes are offered.
Not published
Self-host Can run on your own hardware or cluster (open source or licensed).
No 1
BYOC / VPC Vendor-managed deployment inside your own cloud account.
Not published
Open source Core sandbox runtime is published under an open-source licence.
Not published
Licence Open-source licence of the runtime, if any.
Not published
SDKs / languages Official SDK languages (or supported execution languages where noted).
Not published
Regions Published regions or region count.
Not published
Max vCPU per sandbox vCPU Largest published vCPU count per sandbox on any self-serve or enterprise plan.
Not published
Max memory per sandbox GiB Largest published memory per sandbox.
Not published
Concurrency Published concurrent sandbox limits by plan.
Not published
SOC 2 SOC 2 status as stated by the vendor.
Not published
HIPAA Vendor offers HIPAA-compliant usage/BAA (on any plan).
Not published
2 vCPU + 4 GiB per hour $/hr Hourly list price of one 2 vCPU / 4 GiB sandbox: 2 x the vCPU rate + 4 x the memory rate, from the two published rates. Left empty for self-hosted software and for vendors without both rates. Vendors that bill CPU only while busy (Vercel, Cloudflare, Upstash, Tensorlake, AWS AgentCore) cost less for idle agents than this shows.
$0.06 1
Price vs E2B x E2B The 2 vCPU + 4 GiB hourly price divided by E2B's own ($0.1656 at $0.000014/vCPU-s and $0.0000045/GiB-s). Under 1 is cheaper than E2B.
0.36 1
Status Preview, experimental, beta, sunset or self-hosting caveats the vendor documents.
Managed cloud only; self-hosting no longer supported, BYOC planned. 1
