Comparison
QuickTane vs E2B
Both run untrusted, AI-generated code in isolated sandboxes over an API. The honest short version: QuickTane is the EU-hosted option with longer-lived sessions and per-second billing; E2B is the more mature US platform with a bigger ecosystem. Here's the detail.
At a glance
| QuickTane | E2B | |
|---|---|---|
| Hosting / data residency | EU-hosted | US-hosted |
| Isolation | gVisor (user-space kernel) | Firecracker microVM |
| One-shot runs | Yes | Yes |
| Persistent sessions | Yes — up to 60 min | Yes |
| Filesystem read/write | Yes | Yes |
| Languages | Python, Node.js | Any (custom Docker templates) |
| Custom images/templates | Not yet (fixed images) | Yes |
| Billing | Per second (vCPU-s + GiB-s) | Per second |
| Free tier | Yes — one-time credit | Yes |
| SDKs | Python, Node/TS | Python, JS/TS |
| Webhooks for results | Yes (signed) | — |
| Maturity / ecosystem | Newer, focused | Established, large |

Where QuickTane fits
You need EU data residency
This is the biggest difference. QuickTane runs entirely on EU infrastructure, so code execution and any data your agent processes stay in the EU — which matters for GDPR and regulated workloads. E2B is US-hosted. If your compliance story requires keeping execution in the EU, that alone often makes the decision.
Your agents need sandboxes that don't time out mid-task
QuickTane sessions stay live for up to 60 minutes, so a multi-step agent can install dependencies once, write files, and run many commands against the same persistent environment without the box disappearing under it.
You want strong isolation without running infrastructure
Every sandbox is a fresh gVisor instance — a user-space kernel that intercepts syscalls, much stronger than a shared-kernel container. It runs non-root with dropped capabilities, a read-only root filesystem, deny-all networking with a registry allowlist, and locked-down DNS. You get that boundary with no containers to manage.
You want simple, predictable billing
Usage is metered per second of actual sandbox runtime (vCPU-second + GiB-second), with a free tier to start. No idle agent costs you anything.
Where E2B is the stronger choice
We'd rather you pick the right tool than the wrong one. E2B is a better fit when:
- You need arbitrary languages or a custom environment. E2B's custom Docker templates let you run anything and pin exact versions/dependencies. QuickTane currently ships fixed Python and Node images.
- You want a large, battle-tested ecosystem. E2B is more mature, with a bigger community, more integrations, and more docs and examples out in the wild.
- US hosting is fine (or preferred) and you don't have an EU data-residency requirement.
Choose QuickTane if…
- You need EU data residency for GDPR or regulated data.
- Your agents run multi-step workflows and need longer-lived, stateful sessions.
- You want strong isolation and zero ops, on Python or Node, with per-second billing.
Choose E2B if…
- You need custom runtimes / arbitrary languages via your own images.
- You want the most mature ecosystem and US hosting is acceptable.
