Dependencies

C Binary (un1) — requires libcurl and libwebsockets:

sudo apt install build-essential libcurl4-openssl-dev libwebsockets-dev
wget unsandbox.com/downloads/un.c && gcc -O2 -o un un.c -lcurl -lwebsockets

SDK Implementations — most use stdlib only (Ruby, JS, Go, etc). Some require minimal deps:

pip install requests  # Python

Execute Code

Run a Script

./un hello.py
./un app.js
./un main.rs

With Environment Variables

./un -e DEBUG=1 -e NAME=World script.py

With Input Files (teleport files into sandbox)

./un -f data.csv -f config.json process.py

Get Compiled Binary (teleport artifacts out)

./un -a -o ./bin main.c

Interactive Sessions

Start a Shell Session

# Default bash shell
./un session

# Choose your shell
./un session --shell zsh
./un session --shell fish

# Jump into a REPL
./un session --shell python3
./un session --shell node
./un session --shell julia

Session with Network Access

./un session -n semitrusted

Session Auditing (full terminal recording)

# Record everything (including vim, interactive programs)
./un session --audit -o ./logs

# Replay session later
zcat session.log*.gz | less -R

Collect Artifacts from Session

# Files in /tmp/artifacts/ are collected on exit
./un session -a -o ./outputs

Session Persistence (tmux/screen)

# Default: session terminates on disconnect (clean exit)
./un session

# With tmux: session persists, can reconnect later
./un session --tmux
# Press Ctrl+b then d to detach

# With screen: alternative multiplexer
./un session --screen
# Press Ctrl+a then d to detach

List Active Sessions

./un session --list

# Output:
# Active sessions: 2
#
# SESSION ID                               CONTAINER            SHELL      TTL      STATUS
# abc123...                                unsb-vm-12345        python3    45m30s   active
# def456...                                unsb-vm-67890        bash       1h2m     active

Reconnect to Existing Session

# Reconnect by container name (requires --tmux or --screen)
./un session --attach unsb-vm-12345

# Use exit to terminate session, or detach to keep it running

Terminate a Session

./un session --kill unsb-vm-12345

API Key Management

Check Key Status

# Check if your API key is valid
./un key

# Output:
# Valid: key expires in 30 days

Extend Expired Key

# Open the portal to extend an expired key
./un key --extend

# This opens the unsandbox.com portal where you can
# add more credits to extend your key's expiration

Authentication

Credentials are loaded in priority order (highest first):

# 1. CLI flags (highest priority)
./un -p unsb-pk-xxxx -k unsb-sk-xxxxx script.py

# 2. Environment variables
export UNSANDBOX_PUBLIC_KEY=unsb-pk-xxxx-xxxx-xxxx-xxxx
export UNSANDBOX_SECRET_KEY=unsb-sk-xxxxx-xxxxx-xxxxx-xxxxx
./un script.py

# 3. Config file (lowest priority)
# ~/.unsandbox/accounts.csv format: public_key,secret_key
mkdir -p ~/.unsandbox
echo "unsb-pk-xxxx-xxxx-xxxx-xxxx,unsb-sk-xxxxx-xxxxx-xxxxx-xxxxx" > ~/.unsandbox/accounts.csv
./un script.py

Requests are signed with HMAC-SHA256. The bearer token contains only the public key; the secret key computes the signature (never transmitted).

Resource Scaling

Set vCPU Count

# Default: 1 vCPU, 2GB RAM
./un script.py

# Scale up: 4 vCPUs, 8GB RAM
./un -v 4 script.py

# Maximum: 8 vCPUs, 16GB RAM
./un --vcpu 8 heavy_compute.py

Live Session Boosting

# Boost a running session to 2 vCPU, 4GB RAM
./un session --boost sandbox-abc

# Boost to specific vCPU count (4 vCPU, 8GB RAM)
./un session --boost sandbox-abc --boost-vcpu 4

# Return to base resources (1 vCPU, 2GB RAM)
./un session --unboost sandbox-abc

Session Freeze/Unfreeze

Freeze and Unfreeze Sessions

# Freeze a session (stop billing, preserve state)
./un session --freeze sandbox-abc

# Unfreeze a frozen session
./un session --unfreeze sandbox-abc

# Note: Requires --tmux or --screen for persistence

Persistent Services

Create a Service

# Web server with ports
./un service --name web --ports 80,443 --bootstrap "python -m http.server 80"

# With custom domains
./un service --name blog --ports 8000 --domains blog.example.com

# Game server with SRV records
./un service --name mc --type minecraft --bootstrap ./setup.sh

# Deploy app tarball with bootstrap script
./un service --name app --ports 8000 -f app.tar.gz --bootstrap-file ./setup.sh
# setup.sh: cd /tmp && tar xzf app.tar.gz && ./app/start.sh

Manage Services

# List all services
./un service --list

# Get service details
./un service --info abc123

# View bootstrap logs
./un service --logs abc123
./un service --tail abc123  # last 9000 lines

# Execute command in running service
./un service --execute abc123 'journalctl -u myapp -n 50'

# Dump bootstrap script (for migrations)
./un service --dump-bootstrap abc123
./un service --dump-bootstrap abc123 backup.sh

# Freeze/unfreeze service
./un service --freeze abc123
./un service --unfreeze abc123

# Service settings (auto-wake, freeze page display)
./un service --auto-unfreeze abc123      # enable auto-wake on HTTP
./un service --no-auto-unfreeze abc123   # disable auto-wake
./un service --show-freeze-page abc123   # show HTML payment page (default)
./un service --no-show-freeze-page abc123  # return JSON error instead

# Redeploy with new bootstrap
./un service --redeploy abc123 --bootstrap ./new-setup.sh

# Destroy service
./un service --destroy abc123

Snapshots

List Snapshots

./un snapshot --list

# Output:
# Snapshots: 3
#
# SNAPSHOT ID                              NAME             SOURCE     SIZE     CREATED
# unsb-snapshot-a1b2-c3d4-e5f6-g7h8        before-upgrade   session    512 MB   2h ago
# unsb-snapshot-i9j0-k1l2-m3n4-o5p6        stable-v1.0      service    1.2 GB   1d ago

Create Session Snapshot

# Snapshot with name
./un session --snapshot unsb-vm-12345 --name "before upgrade"

# Quick snapshot (auto-generated name)
./un session --snapshot unsb-vm-12345

Create Service Snapshot

# Standard snapshot (pauses container briefly)
./un service --snapshot unsb-service-abc123 --name "stable v1.0"

# Hot snapshot (no pause, may be inconsistent)
./un service --snapshot unsb-service-abc123 --hot

Restore from Snapshot

# Restore session from snapshot
./un session --restore unsb-snapshot-a1b2-c3d4-e5f6-g7h8

# Restore service from snapshot
./un service --restore unsb-snapshot-i9j0-k1l2-m3n4-o5p6

Delete Snapshot

./un snapshot --delete unsb-snapshot-a1b2-c3d4-e5f6-g7h8

Images

Images are independent, transferable container images that survive container deletion. Unlike snapshots (which live with their container), images can be shared with other users, transferred between API keys, or made public in the marketplace.

List Images

# List all images (owned + shared + public)
./un image --list

# List only your images
./un image --list owned

# List images shared with you
./un image --list shared

# List public marketplace images
./un image --list public

# Get image details
./un image --info unsb-image-xxxx-xxxx-xxxx-xxxx

Publish Images

# Publish from a stopped or frozen service
./un image --publish-service unsb-service-abc123 \
   --name "My App v1.0" --description "Production snapshot"

# Publish from a snapshot
./un image --publish-snapshot unsb-snapshot-xxxx-xxxx-xxxx-xxxx \
   --name "Stable Release"

# Note: Cannot publish from running containers - stop or freeze first

Create Services from Images

# Spawn a new service from an image
./un image --spawn unsb-image-xxxx-xxxx-xxxx-xxxx \
   --name new-service --ports 80,443

# Clone an image (creates a copy you own)
./un image --clone unsb-image-xxxx-xxxx-xxxx-xxxx

Image Protection

# Lock image to prevent accidental deletion
./un image --lock unsb-image-xxxx-xxxx-xxxx-xxxx

# Unlock image to allow deletion
./un image --unlock unsb-image-xxxx-xxxx-xxxx-xxxx

# Delete image (must be unlocked)
./un image --delete unsb-image-xxxx-xxxx-xxxx-xxxx

Visibility & Sharing

# Set visibility level
./un image --visibility unsb-image-xxxx-xxxx-xxxx-xxxx private   # owner only (default)
./un image --visibility unsb-image-xxxx-xxxx-xxxx-xxxx unlisted  # can be shared
./un image --visibility unsb-image-xxxx-xxxx-xxxx-xxxx public    # marketplace

# Share with specific user
./un image --grant unsb-image-xxxx-xxxx-xxxx-xxxx \
   --key unsb-pk-friend-friend-friend-friend

# Revoke access
./un image --revoke unsb-image-xxxx-xxxx-xxxx-xxxx \
   --key unsb-pk-friend-friend-friend-friend

# List who has access
./un image --trusted unsb-image-xxxx-xxxx-xxxx-xxxx

Transfer Ownership

# Transfer image to another API key
./un image --transfer unsb-image-xxxx-xxxx-xxxx-xxxx \
   --to unsb-pk-newowner-newowner-newowner-newowner
