Deno vs E2B

API-driven Linux microVMs for untrusted code, from the Deno team. Deno Deploy, its hosting platform, has an announced shutdown window, so treat it as migration-sensitive. Deno does not publish comparable vCPU and memory rates, so no hourly price is compared; E2B lists $0.166 an hour for a 2 vCPU / 4 GiB sandbox.

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 Deno instead of E2B when

No field in this dataset favours Deno over E2B. Choose it when its scope matches your constraint: API-driven Linux microVMs for untrusted code, from the Deno team. Deno Deploy, its hosting platform, has an announced shutdown window, so treat it as migration-sensitive.

Stay on E2B when

pause has to keep running memory as well as files: E2B's pause saves both, and Deno does not state memory state in our data.
you need a SOC 2 report: E2B states Type II, and Deno states none in our data.
stability matters: 2026-10-09 announcement: Deno team joining Cloudflare; Deno Deploy runs for six months before shutdown.
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 Deno facts

Source per value

Isolation Isolation technology the vendor states for each sandbox.: microVM 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.: Not published
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.: Not published
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.: Not published
Free tier detail What the free tier or credit includes, as published.: Not published
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.: Under one second (vendor claim). 1
Max session length Longest single sandbox session by plan, as published.: Up to 30 minutes per sandbox session 1
Persistence / snapshots Filesystem state can be kept between runs (snapshots, persistent disks, volumes).: Not published
Pause / resume A sandbox can be paused, suspended, hibernated or put in standby and resumed later.: Not published
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).: Not published
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.: Amsterdam, Chicago 1
Max vCPU per sandbox vCPU Largest published vCPU count per sandbox on any self-serve or enterprise plan.: 2 1
Max memory per sandbox GiB Largest published memory per sandbox.: 4 1
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.: Not published
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.: Not published
Status Preview, experimental, beta, sunset or self-hosting caveats the vendor documents.: 2026-10-09 announcement: Deno team joining Cloudflare; Deno Deploy runs for six months before shutdown. 2
