The Best Microsoft Teams Alternative
A safe and free tool for remote collaboration
Teams is powerful but heavy: paid tiers, limited free features, mandatory accounts, and centralized storage of messages and metadata – not ideal for small groups that want simple, private communication.
EXTRA SAFE is a lightweight, anonymous alternative. No accounts, stored history, or time limits – just encrypted P2P calls, screen sharing, and auto-clearing chats. Up to five people can join instantly from the app or browser.
EXTRA SAFE vs Microsoft Teams
Video Calls
Peer-to-peer, no time limits, E2EE by design
Anonymous, P2P calls with direct streams between devices, protected with asymmetric encryption. Unlimited time for up to 5 people. No user data or metadata is stored. In-call E2EE, P2P chat, and file sharing. Screen sharing is available in the browser lite version.
Server-routed, E2EE limited, logs retained
Routes calls through Microsoft’s cloud servers. E2EE applies only to manually enabled 1:1 VoIP calls and disables some features. Group calls and meetings aren’t E2EE; metadata and call logs may be stored for compliance. Time limits vary by subscription plan.
Chats
P2P chats, auto-delete, zero retention
A P2P, E2E encrypted in-call messaging and media sharing, plus direct chats with disappearing messages by default. All connections use asymmetric cryptography with keys generated and stored only on users’ devices, so only participants see the content.
Server-stored chat, no disappearing messages
All chat messages are stored on Microsoft servers and retained for compliance and organizational policies. E2EE does not apply to chat; data retention, logging, and backups follow enterprise settings. No disappearing message options.
Encryption & Security
E2EE by default, locally managed keys, ephemeral chats
Asymmetric E2EE protects all communication: messaging, file transfer, calls. Private keys stay on users’ devices, and public keys secure every session. Servers don’t have access to content or critical metadata, and nothing is retained: chats auto-clear on your timer, and in-call messages disappear the moment the session ends.
Partial E2EE, corporate cloud dependency
Encrypts data in transit and at rest, but still relies on Microsoft’s cloud, which can access keys when needed. E2EE is limited to manually enabled 1:1 VoIP calls; group calls, meetings, chats, and files aren’t E2E encrypted. Metadata and logs are retained for compliance.
Anonymous Access/Login
Anonymous and frictionless
Identity-free: choose a display name in the app, and receive your unique number. Start a meeting and invite others via a link; they can join, even without installing the app. You can also create a quick call for up to 5 people in the EXTRA SAFE browser lite version – without sign-up
Full identity onboarding required
Requires a Microsoft account, identity details, and organizational association. Email or enterprise login is mandatory.
Privacy & Data Collection
Zero data collection
No collection of user identities, metadata, or message history: storage is encrypted and temporary by default, following your timer.
Extensive metadata and organizational data retention
Teams collects chat and call content, files, profile information, diagnostics, and engagement metadata. This data is stored across Microsoft 365 services and is accessible to organization admins through compliance and eDiscovery tools. Connected Microsoft cloud services may also receive usage data when enabled.
Pricing & Limits
Free and unlimited
Completely free, with no subscriptions, time limits, or hidden fees. All features – video calls, messaging, screen sharing, and file transfer – are available without restriction.
Feature-gated by pricing tiers
Free version includes time limits, storage limits, and locked features. Full functionality requires a paid Microsoft 365 plan.
Corporate Independence
Independent and not part of a large cloud or advertising ecosystem.
Fully integrated with Microsoft 365, Azure cloud, and enterprise systems.
Guest Joining
Anyone can join instantly via browser link without registration or even an app installed.
