Nightshift — autonomous agent orchestrator with Firecracker VMs

Nightshift

Autonomous agent orchestrator with Firecracker VM isolation.

Nightshift runs AI agents in isolated Firecracker microVMs on bare-metal infrastructure. Each agent gets its own VM with a dedicated filesystem, network, and resource limits — so agents can execute code, edit files, and make network calls without affecting the host or each other.

Installation

uv add nightshift-sdk

or

pip install nightshift-sdk

Quick Start

Define an agent with NightshiftApp and AgentConfig:

from nightshift import NightshiftApp, AgentConfig
from claude_agent_sdk import query, ClaudeAgentOptions

app = NightshiftApp()

@app.agent(
    AgentConfig(
        workspace="./my-project",
        vcpu_count=2,
        mem_size_mib=2048,
        timeout_seconds=1800,
    )
)
async def code_reviewer(prompt: str):
    async for message in query(
        prompt=prompt,
        options=ClaudeAgentOptions(
            cwd="/workspace",
            allowed_tools=["Read", "Glob", "Grep"],
            model="claude-sonnet-4-6",
        ),
    ):
        yield message

Deploy to a Nightshift platform:

nightshift login --url https://api.nightshift.sh
nightshift deploy agent.py
nightshift run code_reviewer --prompt "Review the auth module for security issues"

Or run locally on a machine with Firecracker:

nightshift run code_reviewer agent.py --prompt "Review the auth module"

AgentConfig

Parameter	Default	Description
workspace	""	Host directory to mount into the VM at /workspace
vcpu_count	2	Number of vCPUs allocated to the VM
mem_size_mib	2048	Memory in MiB allocated to the VM
timeout_seconds	1800	Maximum agent execution time (30 min default)
forward_env	[]	Environment variables to forward from host
env	{}	Static environment variables set in the VM
