Daytona vs Blaxel Daytona is 20% cheaper per agent run

Which is better, Daytona or Blaxel?

It depends on whether you need GPUs or instant resume. For agents that mostly wait on a model, Runtime has the lowest bill: $0.64 for 1,000 one-minute runs, against $2.76 on Daytona and $3.45 on Blaxel, and a pause keeps memory and processes for up to a year. Pick Daytona for GPU sandboxes or Windows machines; pick Blaxel for a resume in milliseconds or fleets over 100,000 concurrent sandboxes on its top tier.

At a glance

Why do Daytona and Blaxel charge the same an hour?

It is a coincidence of the rates at this size. Daytona charges two meters: two vCPUs at $0.0504 an hour and 4 GiB at $0.0162, $0.1656 an hour together. Blaxel charges one: 4 GB of memory at $0.0414 an hour, $0.1656 an hour, with the CPU set by the memory. Change the shape and they part. A sandbox that needs 4 cores pays for 8 GB on Blaxel to get them, even if it uses 4 GB; on Daytona, CPU and memory are separate meters.

The real difference is what an idle sandbox costs. Blaxel moves a sandbox to standby about 15 seconds after its last connection closes, charges nothing for compute there, and resumes it in about 25 ms. Those 15 seconds are billed, so a one-minute run costs a quarter more on Blaxel than its hourly price suggests. Daytona keeps billing a running sandbox until it is stopped, 15 idle minutes by default.

Runtime charges measured CPU, so the time an agent spends waiting on a model costs only a floor of a twentieth of a vCPU, and memory is chosen apart from vCPUs.

Cost for the same job

1,000 runs of a 2 vCPU, 4 GiB sandbox (4 GB on Blaxel). 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 a month that is $276.00 on Daytona, $345.00 on Blaxel and $63.89 on Runtime. With both CPUs busy for the whole minute, it is $1.33 on Runtime against $2.76 on Daytona and $3.45 on Blaxel, so Runtime is cheaper however busy the sandbox is. The Blaxel figure includes the 15 seconds or so each sandbox stays billed after its run, before standby. Disk, snapshots, network and free credits are left out.

What happens between an agent's turns?

This decides the bill more than the rates do for an agent that works in bursts.

• Daytona: the sandbox runs, and bills, until it is stopped or has been idle for 15 minutes. On its VM class, a pause keeps files and memory.
• Blaxel: the sandbox drops to standby on its own and costs only snapshot storage, $0.20 per GB a month, until the next request.
• Runtime: set idlePauseSeconds and the sandbox pauses with its files, memory and running processes; the next request wakes it. Paused storage costs $0.08 per GB a month.

TypeScriptimport { Sandbox } from "withruntime";const sbx = await Sandbox.create({ idlePauseSeconds: 600 }); // ten idle minutesawait sbx.update({ idlePauseSeconds: 1800 }); // change it later; 0 turns it off

Which one to pick

• Pick Daytona if you need GPU sandboxes or Windows machines.
• Pick Blaxel for sandboxes that go to standby by themselves and resume in milliseconds, or for very large fleets: its top tier runs over 100,000 concurrent sandboxes.
• Pick Runtime for a microVM on every sandbox at over 75% below either price, measured CPU with memory chosen separately, and pause that keeps memory and processes for up to a year.

Switch from either one

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

TypeScriptimport { Daytona } from "withruntime/daytona"; // was: from "@daytona/sdk"

Pythonfrom withruntime.daytona import Daytona  # was: from daytona import Daytona

Blaxel code needs one import too, withruntime/blaxel in place of @blaxel/core (Python withruntime.blaxel in place of blaxel.core); its standby becomes a pause with automatic wake. To port to Runtime's own calls instead, create becomes Sandbox.create() and a process becomes exec; the migration table lists each call.

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. npx withruntime compare --from blaxel prices the sandboxes you ran at Blaxel's published rates. Credit you add within 30 days of signing up is matched, up to $1,000 in total. The full side-by-sides are Runtime vs Daytona and Runtime vs Blaxel.
