Heaptree | Launch Virtual Machines With One Line of Code

What is Heaptree?

Heaptree lets you launch secure cloud instances with one line of code. Perfect for AI workloads, asynchronous tasks, or any application that needs on-demand compute.

Getting Started

1. Install the SDK

pip install htsdk

2. Login from your terminal

This opens your browser to sign in with GitHub/Google and automatically configures your API key.

heaptree login

This will:

• Save your key to ~/.heaptree/config.json
• Add HEAPTREE_API_KEY to your shell profile (e.g. ~/.zshrc)

Open a new terminal (or run source ~/.zshrc) for the environment change to take effect.

3. Create your first node

import os
from heaptree import Heaptree

# Initialize the client
client = Heaptree(api_key=os.getenv("HEAPTREE_API_KEY"))

# Create a new node
result = client.create_node(
    num_nodes=1,
    node_size="small"
)

print(f"Node created: {result.node_id}")

4. Use your node

# Run a command on the node
response = client.run_command(
    node_id=result.node_id,
    command="echo 'Hello from Heaptree!'"
)

# Clean up when done
client.terminate_node(result.node_id)

Local development (no PyPI)

Use any of the following to test changes locally without publishing to PyPI.

Option A: Run the CLI directly from source (no install)

cd /Users/jordanhilado/projects/heaptree/sdk
python -m heaptree.cli login

Option B: Editable install into your environment

cd /Users/jordanhilado/projects/heaptree/sdk

# (optional) create/activate a virtualenv or conda env
python -m venv .venv
source .venv/bin/activate
# conda alternative: conda activate heaptree

# ensure old installs don't shadow your local one
python -m pip uninstall -y htsdk heaptree || true

# install locally in editable mode
python -m pip install -e .

# run the CLI
heaptree login

Verify the local package is being used:

which heaptree
python -c "import heaptree, inspect; print(heaptree.__file__)"

Expected output paths should point inside .../projects/heaptree/sdk/....

Optional: Override platform URL

export HEAPTREE_PLATFORM_URL="https://staging.heaptree.com"
python -m heaptree.cli login

Optional: Reset local login state

rm -f ~/.heaptree/config.json

After a successful login that updates your shell profile, reload your shell:

source ~/.zshrc
echo "$HEAPTREE_API_KEY"

Switch back to the PyPI build later

python -m pip uninstall -y htsdk heaptree
python -m pip install htsdk

Updating the SDK

To update to the latest version of the SDK, run:

pip install --upgrade htsdk

Or use the shorthand:

pip install -U htsdk

To check your current SDK version:

pip show htsdk

Features

• Node Management: Create, terminate, and manage cloud instances
• File Operations: Upload and download files to/from nodes
• Command Execution: Run commands remotely on your nodes
• Multiple Node Support: Create and manage multiple nodes simultaneously

Install Python packages in Firecracker sandboxes

import os
from heaptree import Heaptree

client = Heaptree(api_key=os.getenv("HEAPTREE_API_KEY"))
node = client.create(
    lifetime_seconds=300,
    pip_install=["numpy", "boto3", "requests"]
)

Git in Firecracker nodes

from heaptree import Heaptree

client = Heaptree(api_key=os.getenv("HEAPTREE_API_KEY"))
node = client.create()

# Clone a public repo
node.git_clone(
    url="https://github.com/user/repo.git",
    path="workspace/repo"
)

# Clone with authentication (e.g., PAT)
node.git_clone(
    url="https://github.com/user/private-repo.git",
    path="workspace/private-repo",
    username="git",
    password="personal_access_token"
)

# Clone a specific branch
node.git_clone(
    url="https://github.com/user/repo.git",
    path="workspace/repo-branch",
    branch="develop"
)

# Get repo status
status = node.git_status("workspace/repo")
print(status.current_branch, status.ahead, status.behind)
for f in status.file_status:
    print(f.name, f.status)

# List branches
branches = node.git_branches("workspace/repo")
for b in branches.branches:
    print(b)

List files and directories in Firecracker nodes

from heaptree import Heaptree
import os

client = Heaptree(api_key=os.getenv("HEAPTREE_API_KEY"))
node = client.create()

# List files in a directory
files = node.list_files("workspace")

for file in files:
    print(f"Name: {file.name}")
    print(f"Is directory: {file.is_dir}")
    print(f"Size: {file.size}")
    print(f"Modified: {file.mod_time}")

Create directories with specific permissions

from heaptree import Heaptree
import os

client = Heaptree(api_key=os.getenv("HEAPTREE_API_KEY"))
node = client.create()

node.create_folder("workspace/new-dir", "755")

File permissions (set/get and recursive)

from heaptree import Heaptree
import os

client = Heaptree(api_key=os.getenv("HEAPTREE_API_KEY"))
node = client.create()

# Set file permissions
node.set_permissions("workspace/file.txt", "644")

# Get file permissions
file_info = node.get_permissions("workspace/file.txt")
print(f"Permissions: {file_info.permissions}")

# Set directory permissions recursively
node.set_directory_permissions_recursive("workspace/new-dir", "755")
