Nextcloud Talk
The first privacy-respecting communication platform for online collaboration through meetings, chat and webinars. All in one application.
Why Nextcloud Talk?
Nextcloud Talk empowers secure collaboration for hybrid teams, enhancing productivity and connectivity from anywhere.
Take back the control
Stay in control over your data and improve the resiliency of your critical communication platform! Nextcloud Talk offers digital sovereignty without vendor lock-in and dependencies on proprietary vendors. Its open-source architecture enables organizations to customize Talk to meet specific needs and integrate it into existing systems.
Nextcloud Talk is ideal for on premise private cloud deployments or hosting with a trusted, local provider!
Unlock advanced collaboration
Nextcloud Talk makes hybrid work easy. It combines chat, video calls, and webinars together with file sharing and document editing within a single application, supported by advanced AI-driven features designed to simplify daily workflows.
Collaborate with your colleagues on documents directly within chats or calls, or have a real-time brainstorming session with the whiteboard. For more mindfulness at work, Nextcloud talk comes with built-in functions for a healthier meeting culture.
Highly secure and compliant
With self-hosting options and robust data protection, Nextcloud Talk offers the security and compliance you need, without sacrificing control. It's the first GDPR-compliant, private cloud collaboration tool that consolidates all essential functions for efficient collaboration in one application, and the only complete collaboration platform also deployable in airgap environments.
UNIQUE PROTECTION
A platform you can trust
Nextcloud Talk protects your communication better than other team collaboration platforms like Microsoft Teams or Slack, making sure your data stays on your servers. Nextcloud Talk goes further than other encrypted communication technologies by preventing even metadata from leaking. This ensures you stay in complete control of your communications.
Nextcloud Talk is the only solution that consolidates all essential functions for efficient collaboration into a single application, while ensuring full data control and independence. It's the only high-security collaboration platform that can also be deployed in air-gapped environments.
With its multi-layered encryption, brute force protection, AI-based suspicious login detection, passwordless login, and the assurance of a $10,000 security bug bounty program, Nextcloud Talk provides customers the confidence that their communication and collaboration remain confidential at all times.
Trusted by thousands of organizations
The most popular self-hosted collaboration solution for tens of millions of users at thousands of organizations across the globe
Compliance
Self-hosting communication simplifies compliance with national and international privacy and security regulations. By relying on existing, vetted infrastructure, your current compliance and security processes apply to Nextcloud Talk.
GDPR, CCPA and more
The GDPR (General Data Protection Regulation) makes organizations liable for any violations of user privacy and deviations from a high data security standard.
Legislation like the CCPA (California Consumer Privacy Act of 2018) brings similar regulation to other countries.
Nextcloud has extensive GDPR compliance capabilities.
ePrivacy Regulation
The upcoming EU ePrivacy Regulation is designed as a complement to the GDPR. The objective is to reinforce trust and security in the Digital Single Market by ensuring that electronic communications from Europeans are confidential regardless of the technology used. The ePrivacy Regulation protects the confidentiality of electronic communications and information on devices, independently whether it is personal or non-personal data.
Nextcloud is designed to protect the confidentiality of communications and fully prepares customers for the upcoming ePrivacy Regulation.
Why metadata and self hosting matter
Metadata, often described as everything except the content of your communications, has less legal protection but can be incredibly revealing. From a list of who somebody talks to and when, much can be inferred! The Electronic Frontier Foundation explains it well on their site.
Of course, service providers might promise not to store and track such meta data, but governments can simply force them if need be. For example, in the UK providers have been forced to record the website visits of their customers.
And that is not even mentioning the fact that even privacy-focused companies can suddenly be sold to a foreign entity. Like with the content of communication, the best way to protect metadata is to ensure it never leaks from your infrastructure in the first place.

Scalability
Easy for private use
Nextcloud Talk is designed for easy installation and operation. Nextcloud hosts a STUN server to facilitate usage behind firewalls and we recommend the installation of a local TURN server to improve connectivity further. Note that calls get fully routed through a TURN server, causing a lot of network traffic.
The peer-to-peer nature of Talk does inflate network traffic, creating one incoming and sending stream per other participant. This places practical limitations on calls that depend on network capabilities. A typical private Nextcloud Talk setup should handle dozens of calls with each up to 6-10 participants, up to 20 if all participants have a good network connection and do not use video. Enterprise limits, however, are in the thousands of participants per call.
Scaling in enterprise setup
To help with scaling, Nextcloud lowers video quality automatically and disables video on large calls. Sending audio and video, as well as the compute power required to decode the video streams on clients, are the biggest limiting factors, with most asymetric internet connections bottlenecked on upstream bandwidth and laptops and mobile devices especially having trouble decoding multiple video streams.
The High Performance Back-end offered by Nextcloud solves the bandwidth bottleneck and allows scaling a single call to much larger numbers of participants, up to hundreds or even thousands.
SCALING FURTHER: WEBINARS, SCHOOL CLASSES
High Performance Back-end
Webinars and other large scale broadcasting type calls are possible with hundreds or thousands of participants. The High Performance Back-end setup includes special features for this.
The HPB also lowers the load from calls on the Nextcloud server, taking care of 'signaling' and optionally enables connecting a SIP bridge so users can dial in by phone into calls. The HPB runs on premise, like Nextcloud itself, or through a hosted offering by our partners. Customers should be aware that it has significant dedicated bandwidth and processing needs. The HPB is available through Nextcloud GmbH.
