DCTS vs Slack
Slack is the dominant commercial team chat tool, hosted entirely on Slack's servers with per-seat pricing and no self-hosting option. DCTS runs on your own infrastructure under the AGPL-3.0 license, with no vendor access to your messages and no recurring per-seat fee.
| Feature | DCTS | Slack |
|---|
| License | AGPL-3.0 | Proprietary |
| Self-hosting | Yes | No |
| Voice chat | Yes, with screensharing and camera | Yes (Huddles) |
| DM encryption | End-to-end encrypted | Not end-to-end encrypted |
| Mobile app | Android | iOS and Android |
DCTS is the better choice for teams that need message data on their own servers, encrypted DMs, and no recurring licensing costs. Slack remains the stronger pick for teams that depend on its integration ecosystem, search at scale across large message archives, or enterprise compliance features like data retention policies and e-discovery.
DCTS vs Microsoft Teams
Microsoft Teams is a proprietary communication tool included with Microsoft 365 subscriptions, tightly integrated with Office apps and hosted on Microsoft's servers. DCTS offers a self-hosted path for teams that want to operate outside the Microsoft ecosystem.
| Feature | DCTS | Microsoft Teams |
|---|
| License | AGPL-3.0 | Proprietary |
| Self-hosting | Yes | No |
| Voice and screensharing | Yes | Yes (full video conferencing) |
| Office 365 integration | None | Deep integration |
| Mobile app | Android | iOS and Android |
DCTS is the right fit for teams outside the Microsoft 365 ecosystem who want full control of their communication stack and no Microsoft data residency. Microsoft Teams is still the better choice for organizations where Outlook, SharePoint, and Office 365 integration is a daily workflow dependency, or where enterprise IT governance requires Microsoft-managed infrastructure.
