Sprites vs Ona
Sprites gives each agent a small Linux VM you create by API, which sleeps when idle and wakes on the next request, and you can start paying as you go today. Ona, formerly Gitpod and now part of OpenAI, is a cloud dev platform for engineering teams and its Codex agent, sold to new customers only through sales.
The companies and products
Sprites
Sprites is Fly.io's product for agents: persistent Linux computers you create by API or CLI, which sleep when idle and wake on the next request.
Each Sprite is a Firecracker microVM with 8 vCPU, memory the platform manages, and a 100 GB ext4 disk that syncs to object storage. It runs one managed Ubuntu image with Claude Code, Codex, Gemini CLI and Cursor preinstalled, gets an HTTPS URL that wakes it, and bills only for the CPU and memory it actually uses while awake. It is built for coding agents, dev environments and user code that sit idle most of the time.

Ona
Ona, formerly Gitpod, is a platform for cloud dev environments and background coding agents, and is now part of OpenAI.
Ona is a different kind of product from bochka: a dev-environment platform, not a sandbox API. Each task or developer gets an isolated VM built from a Dev Container config, which people open in a browser IDE, VS Code or JetBrains, and where Ona's Codex Agent can plan, code, test and open pull requests. It is built for engineering teams who want the same governed environment for every developer and agent; new customers run it in their own AWS or GCP account on an Enterprise contract.
Which use cases each one fits
For each use case, Battleships prices every sandbox provider on the same workload and sorts them from the cheapest monthly bill up. “63rd cheapest of 377” means 62 of the other 376 providers run that workload, with every feature it needs, for less. “With limits” means the provider runs it but misses something, so it is listed after every full match. Open a use case for its whole ranking and what each provider misses.

Performance
There is no comparable CPU measurement for Sprites or Ona: neither is in the hpc-sandbox-benchmarks results we use. bochka did 26.69 Node.js build-and-test runs per second at 4 vCPU / 8 GB in StarSling's run of 2026-09-29, on dedicated AMD Ryzen 9 9950X hosts.
Node.js build-and-test loop at 4 vCPU / 8 GB, higher is better. Measured with the open hpc-sandbox-benchmarks suite. Sprites and Ona have no published run in this suite yet, so there is no like-for-like number to compare.
Pricing in five scenarios
Each bill is priced from the providers' public price lists by the open Battleships engine, with the cheapest plan that runs the scenario.
| Scenario | Sprites, a month | Ona, a month | bochka, a month |
|---|---|---|---|
| One coding agent, workdays 4 vCPU / 8 GB, 50 GB disk, 8 hours a day, 22 days a month, files kept between days | $23 · Pay-as-you-go | $5,030 · Enterprise (AWS Marketplace 12-month contract) · with limits | $20 · $20/mo |
| One agent that never stops 4 vCPU / 8 GB, 50 GB disk, running 24/7 all month | $92 · Pay-as-you-go | $5,140 · Enterprise (AWS Marketplace 12-month contract) · with limits | $26 · $20/mo |
| 50 agents in parallel 50 machines of 4 vCPU / 8 GB at once, 8-hour sessions, 1,100 sessions a month, Docker inside | $1,120 · Pay-as-you-go | $6,521 · Enterprise (AWS Marketplace 12-month contract) · with limits | $317 · $20/mo × 3 seats |
| Sandboxes for your users 2 vCPU / 4 GB, 30,000 sessions of 10 minutes a month, up to 300 at once | $314 · Pay-as-you-go · with limits | $5,432 · Enterprise (AWS Marketplace 12-month contract) · with limits | $200 · $100/mo × 2 seats |
| 1,000 short jobs at once 2 vCPU / 4 GB, 1,000 at once, 3 minutes each, 200,000 jobs a month | $1,134 · Pay-as-you-go · with limits | $5,955 · Enterprise (AWS Marketplace 12-month contract) · with limits | $2,000 · $2000/mo · with limits |
Sprites: Sprites bills CPU time at $0.0385 per CPU-hour and actual memory at $0.021875 per GB-hour, only while the Sprite is awake, plus storage on the bytes you write. Optional plans such as Hero at $100 a month buy fixed allowances that are not credit.
Ona: New Core subscriptions are closed, so the Ona prices here use its Enterprise listing on AWS Marketplace: a 12-month, $60,000 contract, plus compute on your own AWS bill. Real Enterprise prices are negotiated with sales.
Ona: Plans start at $20 a month, and the whole fee is usage credit spent per second on running sandboxes. A stopped sandbox costs nothing and keeps its disk.
Limits in those scenarios
Sprites does not publish how many Sprites can run at once on pay as you go, so 300 user sandboxes and 1,000 jobs at once are not confirmed, and creation is 10 a minute without a plan. No Ona scenario fits as published, because new customers can only buy Enterprise through sales, and the table assumes 3 environments at once since Ona publishes no Enterprise limit. On bochka the 1,000-job burst gets queued above 90 starts a minute and needs more daily starts than the $2,000 plan allows.
| Scenario | Sprites | Ona | bochka |
|---|---|---|---|
| One coding agent, workdays | None that bite |
| None that bite |
| One agent that never stops | None that bite |
| None that bite |
| 50 agents in parallel |

| None that bite |
| Sandboxes for your users |

Which one should you use?
Use Sprites when
you want to start today without a contract, and your agents or apps sit idle most of the day and should wake on a request.
- Start today, pay for what you use. Useful for small teams: Sprites is self-serve, has no plan fee by default, and bills only the CPU and memory a Sprite uses while awake.
- Sleeps when idle, wakes on request. Useful for agents and apps that sit idle most of the day: a Sprite pauses after 30 seconds and wakes on the next request.
- Limits on what an agent can reach. Useful if you want guardrails: Sprites can allowlist outbound domains and limit which API paths a stored token can call.
Use Ona when
your engineers want a governed cloud IDE shared with a Codex agent, inside your own AWS or GCP account or with a GPU.
- A full cloud IDE for your team. Useful if your engineers work in the same environments as their agents: Ona has browser, VS Code and JetBrains IDEs with Dev Containers and prebuilds.
- Runs in your own cloud. Useful if environments must run inside your own AWS or GCP account, in a region you pick: Ona's Enterprise runners do that.
- GPU environments. Useful if your agents need a GPU: Ona's Enterprise runners can use GPU types, such as an A10G VM with 16 vCPU and 64 GB.
Where bochka fits
If your own code starts the agents and they work for hours, look at bochka. Sprites is built to sleep between short bursts, and Ona is built for engineers in an IDE and sold through sales. bochka gives each agent a full VM it can shape, an API on every plan, and a machine that keeps its work and can be forked.
A full machine with a screen
Sprites has no systemd and is headless, and neither Sprites nor Ona documents /dev/kvm or a desktop, so emulators, nested VMs and computer-use agents do not run. On Sprites you would build a display and stream layer yourself.
Agents you drive from outside, on any plan
On Sprites you write the code that starts, prompts and watches each agent through exec. On Ona the SDK is Enterprise only, through sales, and its managed agent is Codex. bochka has a prompt, steer and events API from the trial up.
Machines that keep running, keep work and fork
A Sprite pauses and drops connections unless an hour-long task hold is renewed, and an Ona agent stops after 30 idle minutes by default. Neither can copy a running machine, so each parallel attempt starts over.
Use bochka when your code starts and drives agents that work for hours: full VMs with systemd and /dev/kvm, a desktop, open ports, an API on every plan, and forks of running machines. Compare it one to one: bochka vs Sprites and bochka vs Ona.
Questions people ask
Is Sprites cheaper than Ona?
In every scenario we priced, yes: one coding agent on workdays is $23 a month on Sprites against $5,030 on Ona, and 50 agents in parallel are $1,120 against $6,521. Ona's figure uses its AWS Marketplace Enterprise listing, so a real sales quote may differ. bochka comes to $20 and $317 for the same two.
Which is faster, Sprites or Ona?
We can't say: neither has a comparable CPU measurement in the benchmark results we use. A Sprite always has 8 vCPU, and Ona's size depends on the VM class you pick. bochka did 26.69 runs per second at 4 vCPU / 8 GB.
Can Sprites and Ona run Docker?
Both run Docker with root. On Sprites, users report that docker exec fails for containers whose main process is not root, and there is no systemd. Neither documents /dev/kvm, which bochka has in every sandbox.
Can I sign up for Ona the way I can for Sprites?
No. Sprites is self-serve with $30 of trial credit per organization. Ona's billing docs say new Core subscriptions are no longer available, so new customers go through sales for Enterprise.
Which one runs Claude Code?
Sprites preinstalls Claude Code, Codex, Gemini CLI and Cursor, which you run through exec or a console. On Ona the managed agent is Codex, and you install Claude Code yourself. bochka preinstalls seven agents with one API to prompt, steer and watch them.
Is Ona the same as Gitpod?
Yes. Gitpod renamed itself Ona in 2025 and moved toward background coding agents, and Ona is now part of OpenAI.
