Speek! review
A focused choice for anonymous, serverless messaging and file sharing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Speek! is an open-source messaging application for people who prioritize anonymous, serverless communication over conventional account-based messaging. It sends messages and file transfers through the Tor network, uses public keys as user identities, and does not require a phone number or user ID. Its peer-to-peer design avoids intermediary messaging servers, while end-to-end encryption applies to both messages and file transfers. The application supports Windows, macOS, Linux, iOS and Android, with group chats included among its capabilities.
Its strongest distinction is the combination of anonymity, Tor routing and direct peer-to-peer communication. Users can share files anonymously, communicate without a conventional identifier, and keep the architecture focused on avoiding server-based message storage. That narrow emphasis makes Speek! a suitable fit for people who specifically want privacy-oriented peer-to-peer messaging and file sharing. Public-key identities also provide a different model from phone-number-based services, while Android identity backup restoration addresses continuity for Android users.
The same architecture defines where Speek! may be a less natural choice. Organizations seeking centralized administration, familiar account discovery or a conventional server-backed messaging workflow may prefer a product built around those needs instead. Its feature set is centered on messaging, file transfers and group chats rather than a broader collaboration suite. Speek! is therefore best suited to privacy-focused individuals and small groups that value anonymous identities and Tor-routed communication. It is less suitable for teams that prioritize centralized control, conventional identity management or a wide range of collaboration functions.
