E2B vs Morph Morph is 40% cheaper per agent run

Which is better, E2B or Morph?

It depends on machine size and branching. For agents that wait on a model, Runtime costs the least, and it stays cheapest when the CPUs are busy: $0.64 for this job, against $1.67 on Morph and $2.76 on E2B. Runtime's forks keep memory, and it has no monthly plan. Pick Morph to branch a running machine into hundreds of replicas, or for machines up to 1,024 vCPUs. Pick E2B to self-host, or for 20 concurrent sandboxes on a free plan.

At a glance

Is Morph cheaper than E2B?

For a 2 vCPU, 4 GB machine, yes. One MCU covers 1 vCPU, 4 GB of memory or 16 GB of disk, and a machine pays for whichever resource needs the most MCUs. 2 vCPUs need 2 MCUs and 4 GB needs 1, so the machine is 2 MCUs: $0.10 an hour. E2B charges $0.1008 for the two vCPUs and $0.0648 for the memory, $0.1656 an hour.

The MCU rule favors shapes with about 4 GB per vCPU. A 2 vCPU machine with 8 GB is still 2 MCUs on Morph, $0.10 an hour, while E2B adds $0.0648 an hour for the extra memory. A machine with more CPU than memory pays for each vCPU on both.

Morph's plans matter too. Its free tier includes no MCUs; the $40 Team plan includes 1,000 and runs 32 devboxes concurrently. E2B's free Hobby plan runs 20 and comes with $100 of credit.

Runtime charges for neither the machine nor its allocation: it measures the CPU a run uses, so an agent waiting on a model pays a floor of a twentieth of a vCPU while it waits.

Cost for the same job

1,000 runs of a 2 vCPU, 4 GiB sandbox (2 MCUs on Morph). Each run lasts 60 seconds and keeps the CPU busy for 20 CPU-seconds: an agent that mostly waits for a model.

At 100,000 runs per month, that is $276.00 on E2B, $166.67 on Morph and $63.89 on Runtime. With both CPUs busy for the whole minute, it is $1.33 on Runtime, against $2.76 on E2B and $1.67 on Morph, so Runtime is cheaper however busy the sandbox is. Plan fees, included credit, storage, network and taxes are left out.

Can I branch a running sandbox?

On Morph, yes: Infinibranch copies a running machine, memory included, to hundreds of parallel replicas. E2B pauses and resumes a sandbox with its memory and processes, and keeps a paused one with no expiry.

Runtime forks a running sandbox into 1 to 100 copies, each with the source's files, memory and running processes, and keeps a snapshot to start more later:

Pythonfrom withruntime import Runtimeruntime = Runtime()image = runtime.images.build(name="data", recipe={"pip": ["pandas"], "apt": ["jq"]},                             on_log=lambda line: print(line["text"]))with runtime.sandboxes.create(image=image["id"]) as base:    forks = base.fork(count=2)  # copies as it is now, running    for fork in forks:        fork.stop()    snapshot = base.snapshot(name="with-pandas", retention_days=7)    with runtime.sandboxes.create(snapshot=snapshot["id"]):        pass    runtime.snapshots.delete(snapshot["id"])

Which one to pick

• Pick E2B for vCPUs and memory set separately, a free plan with $100 of credit and 20 concurrent sandboxes, or a runtime you can self-host under Apache-2.0.
• Pick Morph for machines up to 1,024 vCPUs, branching a running machine into hundreds of replicas, or shareable Devboxes that scale to zero and keep their memory.
• Pick Runtime for 77% below E2B's price and 62% below Morph's on an agent that waits, with no monthly plan, 100 concurrent sandboxes on a paid account, and forks that keep memory.

Switch from either one

From E2B, Runtime's SDK runs your code after one import change:

TypeScriptimport { Sandbox } from "withruntime/e2b"; // was: from "e2b"

Pythonfrom withruntime.e2b import Sandbox  # was: from e2b import Sandbox

From Morph, a started instance becomes Sandbox.create(), commands run with exec, and stopping becomes stop(). A snapshot you start instances from becomes a Runtime snapshot, and a branch becomes fork:

TypeScriptimport { Sandbox } from "withruntime";const box = await Sandbox.create();try {  await box.files.write("/workspace/invoice.py", "print(sum([125, 250, 375]))\n");  console.log((await box.exec("python3 /workspace/invoice.py", { check: true })).stdout);} finally {  await box.stop();}

Or give your coding agent the one instruction in migration: it switches the project on a branch, tests it on the free usage and reports the monthly saving. The full comparisons are Runtime vs E2B and Runtime vs Morph. For evals that fan out from one prepared machine, see agent evals and SWE-bench.
