kombify Sim · Simulation and Testing

Simulate
before you deploy.

Test your homelab infrastructure without risk. Spin up virtual copies of your setup, try changes safely, and deploy with confidence.

Stop breaking production

There is a better way to test infrastructure changes than deploying and praying.

The old way

  • Deploy changes directly to production hardware
  • Break services for hours while debugging
  • No rollback plan when things go wrong
  • Manual testing with no reproducibility

Risky. Slow. Impossible to reproduce.

The Sim way

  • Simulate your entire infrastructure first
  • Test changes safely in isolated environments
  • Deploy with confidence after verification
  • Reproducible test environments every time

Safe. Fast. Reproducible.

Built for real infrastructure

Everything you need to simulate, test, and validate your homelab setup.

Multi-Engine Support

Docker, Incus, QEMU, or Azure — choose the engine that fits your use case. Mix and match across simulations.

Real SSH Access

SSH into simulated nodes exactly like real servers. Test Ansible playbooks and automation workflows.

Pre-Built Templates

Start fast with curated templates for common setups. Single-node, multi-tier, hybrid cloud.

Network Discovery

Scan and map your existing network. Recreate the topology in simulation with one click.

Three ways teams use Sim

Pre-deployment validation, CI/CD integration, migration rehearsal. Same tool, same simulations.

Pre-Deployment Testing

Simulate every change before touching production. Test upgrades, config changes, new services in isolation.

CI/CD Integration

Run full simulations in your pipeline. Validate Ansible, Terraform, and shell scripts against real SSH targets.

Migration Planning

Model the target environment, rehearse the migration, cut over only after you have validated every step.
