kosa8 vs Daytona

01The short verdict

Choose Daytona if

• you need GPUs in a sandbox, up to 8 per sandbox [12];
• you need Windows or macOS sandboxes as well as Linux [2];
• you want cheap container sandboxes and VMs only where you need them [1];
• you need SOC 2 and HIPAA paperwork today [14].

Choose kosa8 if

• every sandbox must be a VM with its own kernel, not a container by default [16];
• sandboxes must run on laptops, your servers or an air-gapped site you fully operate [17];
• you want API keys added by an egress broker so the sandbox never holds them [25];
• you want a verifiable audit log without an Enterprise plan [23].

02Daytona and kosa8, feature by feature

Bracketed numbers point to the sources. "Not documented" means the vendor's own pages did not say on 2026-11-14; it does not mean the feature is missing.

03Where Daytona is stronger

• GPUs. NVIDIA and AMD, up to 8 per sandbox, with spot pricing [12]; kosa8 has none [24].
• More operating systems. Windows and macOS sandboxes [2]; kosa8 sandboxes run Linux.
• Compliance paperwork. SOC 2 Type 2, HIPAA and ISO/IEC 27001 listed in its Trust Center [14]; kosa8 has no SOC 2 report yet [25].
• Free credit and live network rules. $200 of compute without a card [5], and egress rules that change on a running sandbox [8].

04Where kosa8 is different

• A microVM every time. Daytona's default is a container sharing a kernel [1]; every kosa8 sandbox has its own kernel [16].
• You can run all of it. Daytona's BYOC keeps its control plane [4]; kosa8 runs fully on your hardware, offline if needed [17].
• Rewind. kosa8 keeps checkpoints and puts the machine back, processes included [18].
• Freeze and verify. An organization freeze on kosa8 Cloud and a hash-chained log on every plan [21] [23].

05Moving from Daytona to kosa8

Daytona's quickstart creates a sandbox, runs code and a command, and deletes it [13] [15].

Daytona, from its docs:

from daytona import Daytona, DaytonaConfig
config = DaytonaConfig(api_key="YOUR_API_KEY") # Replace with your API key
daytona = Daytona(config)
sandbox = daytona.create()
response = sandbox.process.code_run('print("Hello World")')
print(response.result)
response = sandbox.process.exec("ls -la")
print(response.result)
sandbox.delete()

The same on kosa8 Cloud (Python, pip install kosa8):

from kosa8 import Kosa8Cloud

cloud = Kosa8Cloud()  # reads KOSA8_API_KEY
box = cloud.sandboxes.create(template="python", sleep_after_s=600)
r = box.exec(["python3", "-c", "print('hello')"])
print(r.exit_code, r.stdout)
box.delete()

• process.code_run(code) becomes exec(['python3', '-c', code]); process.exec('ls -la') becomes exec(['ls', '-la']).
• response.result becomes r.stdout, with r.exit_code beside it.
• Daytona's auto-stop maps to sleep_after_s; sandbox.delete() stays box.delete() [18].
• domainAllowList maps to --egress-allow on a local sandbox [20]. GPU sandboxes have no kosa8 equivalent.
• Each kosa8 Cloud exec runs in a fresh container on the sandbox's disk: files under /workspace persist between commands, background processes do not. A buffered exec stops at 90 seconds; send stream: true for longer commands [18].
• Templates today are base (Alpine), python (Python 3.12) and node (Node.js 22) [18].
• An organization runs up to 20 sandboxes at once on kosa8 Cloud unless you ask for more [19].
