We're thrilled to announce thresh 1.4.0, a major milestone that transforms thresh from a Windows-focused tool into a truly cross-platform development environment manager supporting Windows, Linux, and macOS.

🌍 Cross-Platform Revolution​

thresh 1.4.0 delivers on our promise to support multiple platforms and container runtimes:

Platform Support Matrix​

PlatformRuntime OptionsBinary SizeStatus
Windows 11WSL2~5 MB✅ Production Ready
LinuxDocker, nerdctl, containerd~5 MB✅ Production Ready
macOS (M1/M2/M3)containerd, Docker Desktop~13 MB🧪 Beta (Testers Wanted)

Windows - Enhanced WSL2 Support​

Windows remains a first-class citizen with enhanced WSL2 integration:

  • Faster environment provisioning (< 30s)
  • Better memory management
  • Improved distro lifecycle management
  • UPX compression for 5 MB binaries

Linux - Native Container Support​

thresh now natively supports Linux with multiple container runtimes:

# Works with Docker
thresh up python-dev  # Detects Docker automatically

# Works with nerdctl (containerd)
export CONTAINER_RUNTIME=nerdctl
thresh up node-dev

# Works with raw containerd
export CONTAINER_RUNTIME=containerd
thresh up alpine-minimal

Why this matters:

  • Run thresh on your Linux servers
  • Use in CI/CD pipelines (GitHub Actions, GitLab CI)
  • Lightweight development on cloud VMs
  • Docker Desktop not required

Automatic Runtime Detection​

thresh intelligently detects which container runtime you have:

  1. Checks for WSL2 (Windows)
  2. Checks for Docker
  3. Checks for nerdctl
  4. Falls back to containerd

No configuration needed - it just works!

🎯 Command Structure Improvements​

Grouped Blueprint Commands​

We've reorganized blueprint management for better clarity:

Old (v1.3.0):

thresh blueprints         # List blueprints
thresh generate "..."     # Generate blueprint

New (v1.4.0):

thresh blueprint list              # List blueprints
thresh blueprint generate "..."    # Generate blueprint
thresh blueprint delete <name>     # Delete blueprint (NEW!)

Blueprint Deletion​

You can now clean up generated blueprints:

# List all blueprints
thresh blueprint list

# Delete old test blueprints
thresh blueprint delete test-nginx-1
thresh blueprint delete experiment-php

# Verify deletion
thresh blueprint list

⚡ Parallel Creation (10x Faster)​

Create multiple environments simultaneously:

# Create 5 environments in parallel
thresh up alpine-minimal node-dev python-dev ubuntu-dev azure-cli

# Traditional sequential: ~150s (30s × 5)
# With parallel: ~35s (6x faster!)

Perfect for:

  • CI/CD pipelines
  • Team onboarding
  • Multi-environment testing
  • Demo setups

🚀 Quick Start​

Prerequisites​

Platform-Specific:

  • Windows: Windows 11 with WSL2
  • Linux: Docker, nerdctl, or containerd
  • macOS: containerd or Docker Desktop

AI Features (Optional):

  • GitHub CLI + GitHub Copilot CLI extension

    # Install GitHub CLI
    # Windows: winget install GitHub.cli
    # Linux: sudo apt install gh
    # macOS: brew install gh

    # Authenticate
    gh auth login

    # Install Copilot CLI extension
    gh extension install github/gh-copilot

    Info: https://github.com/features/copilot/cli

First Steps​

# Verify installation
thresh version

# Platform: Linux/Docker, Runtime: Docker
# Platform: Windows, Runtime: WSL2
# Platform: macOS, Runtime: containerd

# List available blueprints
thresh blueprint list

# Create your first environment
thresh up alpine-minimal

# Generate custom blueprint with AI
thresh blueprint generate "Python ML with Jupyter and pandas" --output python-ml

# Create from generated blueprint
thresh up python-ml

📊 Updated Architecture​

thresh 1.4.0 works across all platforms:

🔧 Migration Guide​

From v1.3.0 → v1.4.0​

Command Changes:

# OLD: thresh blueprints
# NEW: thresh blueprint list

# OLD: thresh generate "..."
# NEW: thresh blueprint generate "..."

# NEW: thresh blueprint delete <name>

No Breaking Changes:

  • Existing environments continue to work
  • Configuration files are compatible
  • Blueprints are automatically migrated

📈 What's Next​

  • Enhanced Linux support - More distros, better performance
  • Kubernetes integration - Deploy to k8s clusters
  • Remote environments - SSH-based provisioning
  • GitHub Actions integration - Official action for CI/CD
