Plexichat is built for teams that need ownership of data, infrastructure, and access policies. This page shows how a self-hosted stack changes control boundaries compared to vendor-hosted SaaS.
| Capability | Plexichat | Rocket.Chat | Mattermost |
|---|---|---|---|
| Encryption Root | ✓ Hardware (TPM 2.0) | ✗ Software-Only | ✗ Software-Only |
| Data Custody | ✓ True Ownership | Limited (Cloud Focus) | Complex (Enterprise) |
| Architecture | ✓ Fully Decoupled | Monolithic Core | Service-Heavy |
| Real-time Stack | ✓ FastAPI / SFU | Meteor / Legacy JS | Go / Manual Sync |
| Bootstrap | ✓ Production-ready defaults | Setup Wizard Req. | DB Migrations First |
While Rocket.Chat and Mattermost offer encryption, they typically rely on software-managed keys stored on the filesystem or in database variables. If the server is compromised, the keys are vulnerable.
Plexichat changes the model: Our master keys are derived from physical hardware (TPM 2.0). Even with root access to the OS, the encryption root cannot be exported, ensuring your organization’s data remains unreadable if the server environment is breached.
Legacy systems often ship as monolithic blocks that are hard to scale and inspect. Plexichat is engineered from the ground up as three distinct, independently deployable layers: a high-performance FastAPI REST engine, a real-time WebSocket Gateway, and a stateless client.
This architecture allows security teams to place fine-grained firewall rules between components and scale the real-time gateway independently of the API logic. Production-ready defaults mean only security tokens and database credentials need configuration.
