TrendMiner’s PlantIntegrations can be installed as WebHost (IIS) or AppHost (self‑hosted). AppHost is a lightweight, simpler alternative that is easier to install, maintain and upgrade. While WebHost currently still provides more flexibility and security features. There is a difference in available features before version 2026.R1.0 and after 2026.R1.0 which I will explain here.
Deployment features before version 2026.R1.0:
These are the most important differences between the two hosting options:
| Feature | WebHost (IIS) | AppHost (Self‑hosted) |
|---|---|---|
| Installation | IIS setup | Simple exe, self‑contained |
| Port configuration | Flexible | Fixed to 8001 |
| Security | TLS/HTTPS, Basic Auth | Relies on network/proxy security |
| Multiple instances | X | Single instance (fixed port) |
| Best for | Complex environments needing full control | Lightweight setups or quick deployments |
Summary:
-
AppHost is currently ideal for small or lightweight setups, quick deployment, and simpler maintenance.
-
WebHost is currently still preferred when you need multiple instances on one server, advanced security features or you can’t use port 8001.
Improvements to AppHost starting from version 2026.R1.0
Below in bold, you can see the improvements which will be made to the AppHosted deployment option:
| Feature | WebHost (IIS) | AppHost (Self‑hosted) |
|---|---|---|
| Installation | IIS setup | Simple exe, self‑contained |
| Port configuration | Flexible | Flexible |
| Security | TLS/HTTPS, Basic Auth | TLS/HTTPS, Basic Auth |
| Multiple instances | X | X |
| Best for | / | Preferred method which can now also be used in Complex environments needing full control |
Summary
-
AppHost is now the preferred way of installing PlantIntegrations since the same security features and port flexibility will be available, in addition to the simple installation and upgrade procedure.
-
WebHost is still supported and can be deployed if necessary.
