E2B Alternatives

E2B: the baseline

Cloud sandboxes for AI agents: each sandbox is a Firecracker microVM that agents drive through Python and JS/TS SDKs. Built for teams shipping coding agents, data-analysis agents and computer-use agents. Its list price for a 2 vCPU / 4 GiB sandbox is $0.166 an hour. Every alternative page on this site sets its numbers against the ones below.

E2B facts

Source per value
Isolation Isolation technology the vendor states for each sandbox.
Firecracker microVM 4
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.
both 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.
$0.0504 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.
$0.0162 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).
$150.00 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.
Hobby: $0 plan fee, one-time $100 usage credit, 10 concurrent sandboxes, 1-hour sessions. 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.
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.
1 h (Hobby), 24 h (Pro) 1
Persistence / snapshots Filesystem state can be kept between runs (snapshots, persistent disks, volumes).
Yes 4
Pause / resume A sandbox can be paused, suspended, hibernated or put in standby and resumed later.
Yes 4
Memory state kept Pause/hibernate preserves running memory state, not only the filesystem.
Yes 4
Fork / branch A running or snapshotted sandbox can be cloned into new sandboxes.
Yes 4
GPU GPU sandboxes are offered.
No 1
Self-host Can run on your own hardware or cluster (open source or licensed).
Yes 3
BYOC / VPC Vendor-managed deployment inside your own cloud account.
Yes 4
Open source Core sandbox runtime is published under an open-source licence.
Yes 3
Licence Open-source licence of the runtime, if any.
Apache-2.0 3
SDKs / languages Official SDK languages (or supported execution languages where noted).
Python, JavaScript/TypeScript 1
Regions Published regions or region count.
US, EU, APAC 4
Max vCPU per sandbox vCPU Largest published vCPU count per sandbox on any self-serve or enterprise plan.
8 1
Max memory per sandbox GiB Largest published memory per sandbox.
8 1
Concurrency Published concurrent sandbox limits by plan.
10 (Hobby), 100 (Pro), 600/1,100 with add-ons 1
SOC 2 SOC 2 status as stated by the vendor.
Type II 4
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.
$0.1656 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.
