Sparks – the European MS Teams replacement compared
Sparks delivers the feature depth of MS Teams – built and hosted in the EU, with no US legal exposure. Same familiar interface, no retraining. Flexible migration paths from Microsoft 365 or open-source backends at low switching cost.
Sparks feature status: May 14, 2026 (Vistameet-Teams & Vista-Teams-Docs). Compliance rows: typical EU SME/public-sector view; verify vendor documentation.
✓ available ⚠ partial ✗ not available
Contacts: For Microsoft Teams, ⚠ on blocked contacts and multiple backends means the capability exists but is implemented differently than in Sparks (for example directory and personal Outlook contacts in the People app, rather than one unified multi-provider address book).
E2EE: Microsoft Teams offers optional meeting E2EE with major limits (policies, licensing, not all clients or meeting features); the matrix uses ⚠ rather than ✓. Teams chat E2EE remains ⚠ compared with full Matrix-style E2EE in Sparks.

Why Sparks instead of Teams?
- ✓ Teams feature depth: video, chat, channels, calendar, tasks, contacts – near-complete parity with MS Teams
- ✓ EU development and EU hosting: No CLOUD Act, no US legal access to your data
- ✓ Familiar interface: Teams-like UI – no retraining, fast adoption
- ✓ Low migration cost: Switch from Microsoft 365 or open source (Nextcloud, OX) at low cost
- ✓ AI assistant: Configurable, context from calendar, contacts and channels – no Copilot surcharge
- ✓ Open protocol: Matrix and WebRTC – no proprietary lock-in, full data sovereignty
Sparks vs. Element – the honest answer
Many prospects know Element as the most well-known Matrix client. Here are the key differences:
- Can I switch from Element to Sparks without losing data?
- Yes. Both are Matrix clients. Your chats, rooms and messages stay in the Matrix network and are immediately visible in Sparks. You simply sign in with your Matrix account.
- What can Sparks do that Element cannot?
- Sparks has an AI assistant with context from all connected backends (MS365, Google, Nextcloud), webinars & townhalls and a significantly more polished client for business users. Element is great for technically proficient users, but is not a complete collaboration product.
- Is Sparks more expensive than Element?
- Sparks Free is free for up to 1 user. Sparks SMB costs €5.99/user/month net. Element One starts at €5/user/month – but without AI, without the features like calendar, todos and contacts. For the feature-to-price ratio, Sparks is better. All prices are net prices; VAT is charged separately at the applicable statutory rate.
- What happens if Element closes?
- Nothing. Your messages are stored in the Matrix network, not with Element. This is the core advantage of the open protocol. Sparks continues to work – and so do all other Matrix clients.
