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 Freestyle instead of E2B when

your bill is the problem: the same 2 vCPU / 4 GiB box lists at $0.132 an hour here against $0.166 on E2B, 20% less.
your agents run longer than E2B's 24-hour Pro session cap: No limit stated ("can run forever").
you want a published start time: Freestyle states 65 ms (a vendor claim), and E2B publishes no figure.
you are prototyping: Free forever: 200 vCPU-hours and 400 GiB-hours per month, 10 concurrent VMs.

Stay on E2B when

you need a SOC 2 report: E2B states Type II, and Freestyle states none in our data.
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 Freestyle facts

Source per value

Isolation Isolation technology the vendor states for each sandbox.: VM 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.: wall clock 1
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.: $0.0403 1
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.: $0.0129 1
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).: $50.00 1
Free tier A free plan, free monthly allowance or sign-up credit exists.: Yes 1
Free tier detail What the free tier or credit includes, as published.: Free forever: 200 vCPU-hours and 400 GiB-hours per month, 10 concurrent VMs. 1
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.: 65 2
Resume time ms Vendor-published resume-from-pause/standby/snapshot time in milliseconds.: 100 3
Startup claim The vendor's startup/resume wording with conditions, quoted or closely paraphrased.: About 65 ms from API request to a ready machine (vendor claim); a suspended VM wakes in under 100 ms with memory restored. 2
Max session length Longest single sandbox session by plan, as published.: No limit stated ("can run forever") 1
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.: Yes 1
Fork / branch A running or snapshotted sandbox can be cloned into new sandboxes.: Yes 1
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.: Not published
Max vCPU per sandbox vCPU Largest published vCPU count per sandbox on any self-serve or enterprise plan.: 32 1
Max memory per sandbox GiB Largest published memory per sandbox.: 64 1
Concurrency Published concurrent sandbox limits by plan.: 10 (Free), 40 (Hobby), 400 (Pro) 1
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.: $0.1322 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.: 0.8 1
Status Preview, experimental, beta, sunset or self-hosting caveats the vendor documents.: Not published

Pricing model: usage
From: $0.0403 vCPU-hour
Pricing note: $0.04032/vCPU-h, $0.0129/GiB-h after included allowances; Hobby $50/mo, Pro $500/mo (fees count toward usage). Pricing checked 2026-11-09.
