froog vs E2B
E2B and froog both give AI agents an isolated Linux machine in the cloud. E2B is built around short code-execution sessions with an SDK; froog gives each agent a whole VM that stays on, keeps its disk and costs about a twelfth as much to run all month.
froog and E2B side by side
| froog | E2B | |
|---|---|---|
| Isolation | Full KVM virtual machine, own kernel | Linux VM (“a fast, secure Linux VM”) |
| Largest sandbox | Up to 8 vCPU, 16 GB memory, 111 GB disk | 1–8 vCPU, 1–8 GiB memory; disk 10 GiB (Hobby) or 20 GiB (Pro) |
| How long it runs | No limit: runs until you stop it, or until its auto-stop timer runs out (an hour by default, up to 30 days, or never) | Up to 1 hour (Hobby) or 24 hours (Pro) at a time, then killed or paused |
| Snapshots and forks | Hourly automatic snapshots, named snapshots as templates, fork into many copies, restore in place (disk); warm resume with programs running for 10 min after a stop | Pause keeps memory and disk, kept indefinitely; resume in about a second |
| Access | SSH, root (passwordless sudo), Docker, Chrome, a desktop in the browser (XFCE; Hyprland and Chromium on Omarchy), /dev/kvm, HTTPS URL for any port | SDK (Python, TypeScript); desktop sandboxes for computer use |
| GPUs | No | No (“Sandboxes are CPU-only”) |
| Price | $0.0274 an hour for 4 vCPU / 8 GB, billed per second while running | $0.000014 per vCPU-second + $0.0000045 per GiB-second ($0.0504 + $0.0162 an hour); Pro $150 a month |
| 4 vCPU / 8 GB, all month | $20 | $242 (+ $150 Pro plan, needed for runs over 1 hour) |
E2B figures are from its own pages, checked on November 12, 2026: e2b.dev/pricing, docs.e2b.dev/sandbox/persistence. The monthly line is 730 hours at list prices with the machine fully used, plan fees and credits not counted. Prices change; tell us if one is out of date. More providers on the pricing page.
When to pick which
Pick E2B if
- You want an SDK-first code interpreter that starts in a fraction of a second and pauses with memory intact.
- You need more than 100 sandboxes at once on a self-serve plan, or bring-your-own-cloud (Enterprise).
Pick froog if
- Agents that work for hours or days: a froog sandbox has no session limit, so nothing is killed at 1 or 24 hours.
- Bigger machines and disks: up to 16 GB of memory and 111 GB of disk, against E2B's 8 GiB and 10–20 GiB.
- A real computer: SSH in, run Docker, open Chrome or the desktop, or start nested VMs with
/dev/kvm. - Cost: a 4 vCPU / 8 GB VM running all month is $20, against about $242 plus the $150 Pro plan.

curl -fsSL https://froog.tech/install | sh
froog login
froog new my-box # ready when SSH works, about a minute
froog exec my-box -- uname -a
froog prompt my-box "write a hello world web server and run it on port 3000"
froog host my-box 3000 # an HTTPS URL for itQuestions
Is froog cheaper than E2B?
Yes, for machines that run a long time. A 4 vCPU / 8 GB sandbox for a full month is $20 at froog and about $242 at E2B's list prices, before E2B's $150 Pro plan. Both bill per second, so short runs cost little at either.
Does froog have a session time limit like E2B?
No. E2B runs a sandbox for up to 1 hour on Hobby and 24 hours on Pro before it is killed or paused. A froog sandbox runs until you stop it, or until its auto-stop timer runs out: an hour by default, up to 30 days, or never.
Can I move from E2B to froog?
Yes. Instead of the E2B SDK you call froog's HTTP API, the Python, TypeScript or Go SDK, or the froog CLI: create a sandbox, run commands with exec, copy files, and stop or fork it. See the docs.
7 days free: 25 hours of running time, 2 sandboxes at once. Then from $0.0137 an hour, billed per second.
