How were these E2B vs Runloop costs computed?

Both vendors run identical workload profiles (sandbox-hours × vCPU/RAM) through the same engine using each vendor's captured USD list rates; the full methodology is on the agent-sandbox-pricing tool page.

E2B vs Runloop

Across 3 benchmark profiles, E2B prices lower in 3 of 3 — by up to ~48% where the gap is widest. Both rows use identical workload inputs and USD list rates from the capture-dated catalog; verify current rates via each vendor's source link.

Rate Card Snapshot

Vendor	$/vCPU-hr	$/GiB-hr	Billing granularity	Concurrency note
E2B	$0.0504	$0.0162	per-second	Hobby ≤20 concurrent sandboxes; Pro ≤100 (extensible to 1,100). Session caps: ≤1h Hobby, ≤24h Pro.
Runloop	$0.1080	$0.0252	per-second	Plan-based: Basic free + usage; Pro $250/mo + usage; Enterprise custom.

Fit Notes

E2B — Skip if your agents need long-lived environments — Hobby sessions die at 1h and Pro at 24h; this is for short-lived code-running sandboxes.
Runloop — Skip unless you specifically want its Devbox/Blueprint workflow — the highest per-hour rates captured here, with add-on fees on top.
