Agent workspaces

For AI builders, code assistants, and white-label agent products, the sandbox is the development machine. Do not run builds on the user's laptop and upload the result as the primary flow. Create or resume a stable sandbox workspace, write files under /workspace, run package installs/tests/builds inside the sandbox, expose previews from the sandbox, and publish from that sandbox.

sb = miosa.sandboxes.get_or_create(
    "acme-marketing-page",
    template_id="miosa-sandbox",
    persistent=True,
    timeout_sec=86_400,
    idle_timeout_sec=1800,
    snapshot_expiration_days=30,
    keep_last_snapshots=1,
    external_workspace_id="acme",
    external_user_id="jane",
    wait_until_ready=True,
)

sb.files.write_files([
    {"path": "/workspace/package.json", "data": '{"scripts":{"dev":"vite --host 0.0.0.0"}}'},
    {"path": "/workspace/index.html", "data": '<main id="app"></main>'},
])

for event in sb.exec_stream("cd /workspace && npm install && npm run dev -- --port 3000"):
    print(event)

preview = sb.preview.create(port=3000)
print(preview["url"])

create_agent_workspace() is a convenience wrapper around get_or_create() with builder defaults: a 24-hour activity cap, thirty-minute idle snapshot/pause, readiness waiting, 30-day snapshot-retention metadata, keep-last-snapshot metadata, and metadata that marks the sandbox as an agent workspace.

That mirrors the Vercel-style persistent-sandbox model without keeping CPU running forever: activity extends the running session, idle workspaces are checkpointed and paused, and later sessions resume from the checkpoint. Use extend(86_400) before long builds, pause() when the user is done for now, resume() for the next session, snapshots.create() for manual checkpoints, and destroy() only when the workspace should be permanently deleted.

Agent SDK

The Python SDK includes a small agent loop plus provider adapters and a MIOSA tool catalogue. This is the quickest path when you want an LLM to operate MIOSA computers directly.

from miosa.agent import Agent, groq_provider

agent = Agent(
    provider=groq_provider(
        api_key="gsk_...",
        model="moonshotai/kimi-k2-instruct-0905",
    ),
    miosa_api_key="msk_live_...",
)

result = agent.run(
    "Create a sandbox workspace, write /workspace/hello.py, run it, show me "
    "the output, snapshot it, then pause the sandbox.",
    max_iterations=10,
)

print(result.final_text)

Built-in agent tools expose the computer primitive in plain terms:

Tool	Does
create_sandbox	Create/resume a persistent code sandbox workspace for shell/Python/Node/files.
create_computer	Boot a general MIOSA computer for GUI, services, previews, files.
list_computers	List active computers, sandboxes, and desktops.
get_computer	Fetch status, template, size, and public URL.
exec / exec_python	Run bash or Python inside the computer.
read_file / write_file / list_files	Work with files inside the computer.
preview_url	Get the public HTTPS URL for a service port.
pause_sandbox / resume_sandbox	Stop/resume a persistent workspace without deleting files.
extend_sandbox	Extend the activity timeout before long installs, builds, or agent tasks.
snapshot_sandbox	Create a checkpoint after dependency install or a good edit.
deploy_sandbox	Publish to normal MIOSA Deploy.
deploy_docker	Publish to the workspace Docker Deploy appliance.
destroy_computer	Release compute resources when done.

Provider factories include openai_provider, groq_provider, deepseek_provider, openrouter_provider, together_provider, fireworks_provider, mistral_provider, cerebras_provider, perplexity_provider, xai_provider, ollama_provider, lm_studio_provider, and openai_compatible_provider for custom routers.

Sandbox-first builder examples live in examples/:

See BUILDER_GUIDE.md for the full “build your own Lovable with MIOSA sandboxes” product pattern.

Example	What it builds
agent_sandbox_website_builder.py	A Lovable-style website builder flow.
agent_sandbox_app_builder.py	A small app builder with a dev server and preview.
agent_sandbox_artifact_builder.py	Markdown/doc artifacts in /workspace/artifacts.
agent_sandbox_slide_deck_builder.py	A deck workspace under /workspace/deck.

Set GROQ_API_KEY and MIOSA_API_KEY, then run one of the examples. They keep the sandbox alive with miosa_tool_options={"allow_destroy": False} so your app can show previews, inspect generated files, or publish later.

The agent should treat a MIOSA sandbox like the actual development machine: write source files under /workspace, run package managers/tests/builds inside the sandbox, start dev servers inside the sandbox, stream logs/tool results back to your UI, and only publish after a sandbox preview passes a smoke check.

File operations

# Write / read
computer.files.write_file("/workspace/config.json", '{"key": "value"}')
text = computer.files.read_file("/workspace/config.json")

# Upload / download
computer.files.upload("/local/report.pdf", "/workspace/report.pdf")
raw_bytes = computer.files.download("/workspace/report.pdf")

# List / stat / mkdir / rename / chmod
entries = computer.files.list("/workspace")
stat    = computer.files.stat("/workspace/config.json")
computer.files.mkdir("/workspace/output", recursive=True)
computer.files.rename("/workspace/old.txt", "/workspace/new.txt")
computer.files.chmod("/workspace/run.sh", 0o755)

Services (background processes)

svc = computer.services.create(
    name="api",
    command="uvicorn app:main --port 8080",
    working_dir="/workspace",
    env={"DEBUG": "1"},
    port=8080,
)

for log in computer.services.logs(svc.id, follow=True):
    print(log.stream, log.line)

computer.services.restart(svc.id)
computer.services.delete(svc.id)

Publish from sandbox

Sandbox previews are mutable builder URLs. Publishing creates a durable deployment version with a stable url / public_url.

sb = miosa.sandboxes.create(name="clinic-intake", template_id="miosa-sandbox")
sb.files.write_file("/workspace/index.html", "<h1>Clinic intake</h1>")

result = sb.deploy(
    name="clinic-intake",
    output_path="/workspace",
    entrypoint="index.html",
)
print(result["url"])

For full-stack/dynamic apps:

result = sb.deploy(
    name="clinic-intake-api",
    output_path="/workspace",
    build_command="npm run build",
    run_command="npm start",
    port=3000,
    health_check_path="/",
    resources={
        "database": {"auto": True, "engine": "postgresql", "size": "xs"},
        "storage": {"auto": True},
    },
    domain="intake.apps.cliniciq.com",
)

If result["state"] == "building" for a dynamic app, poll miosa.deployments.get(result["deployment_id"]) until it is running. Always display the server-returned url / public_url; do not hardcode preview.miosa.app, api.miosa.app, or <tenant>.miosa.app.

For workspace Docker Deploy, publish from the same sandbox but choose the Docker Deploy target:

result = sb.deploy_docker(
    name="lead-magnet",
    path="/workspace",
    build_command="npm run build",
    run_command="npm start",
    port=3000,
)
print(result.get("url") or result.get("public_url"))

Docker Deploy runs app containers inside the workspace's dedicated MIOSA Docker Deploy appliance VM. It is separate from normal MIOSA dynamic runtime VMs and is useful when a workspace needs many small apps, funnels, lead magnets, APIs, or client sites.

Desktop control

screenshot = computer.screenshot()          # PNG bytes
computer.click(640, 400)
computer.double_click(640, 400)
computer.type("hello world")
computer.key("Return")
computer.scroll("down", 3)
computer.drag(100, 100, 400, 400)

cursor = computer.cursor()
windows = computer.windows()
computer.launch("firefox")

Async usage

import asyncio
from miosa import AsyncMiosa

async def main():
    async with AsyncMiosa(api_key="msk_live_...") as miosa:
        computer = await miosa.computers.create(
            name="async-build", template_type="miosa-sandbox"
        )
        await computer.files.write_file("/workspace/app.py", "print('async!')")
        result = await computer.exec.run("python /workspace/app.py")
        print(result.stdout)
        await computer.destroy()

asyncio.run(main())

White-label / multi-tenant

Tag resources with external_workspace_id and external_user_id to attribute usage to your downstream customers:

computer = miosa.computers.create(
    name="customer-build",
    template_type="miosa-sandbox",
    metadata={
        "external_workspace_id": "dental-office-123",
        "external_user_id": "dr-smith-456",
    },
)

White-label URL layers are separate:

sandbox preview:     https://<port>-<slug>.sandbox.<preview-domain>
durable deployment:  https://<slug>.<deployment-domain>
custom domain:       https://app.customer.com

Tenant preview-domain management is available through miosa.tenant. Tenant deployment-domain routing exists server-side; clients should consume deployment public_url instead of reconstructing it.

Error handling

from miosa import (
    AuthenticationError, NotFoundError, RateLimitError, MiosaError
)

try:
    computer = miosa.computers.get("cmp_doesnt_exist")
except NotFoundError:
    print("Computer not found")
except RateLimitError as e:
    print(f"Rate limited; retry after {e.retry_after}s")
except AuthenticationError:
    print("Check your API key")
except MiosaError as e:
    print(f"API error {e.status}: {e.message}")

Exception hierarchy: MiosaError > AuthenticationError (401), InsufficientCreditsError (402), PermissionError (403), NotFoundError (404), ValidationError (422), RateLimitError (429), ServerError (5xx), ConnectionError, TimeoutError.
