Holepunch

Holepunch is a software publisher focused on peer-to-peer technology, developing applications and infrastructure that allow users to communicate and share data directly with one another without relying on centralized servers. Its approach is built around an open-source peer-to-peer stack, commonly associated with the Hypercore protocol family, which provides the building blocks for distributed data replication, streaming, and identity management. The company's flagship product, Keet, is a peer-to-peer chat application that applies this architecture to everyday communication. Keet offers end-to-end encrypted private messaging, voice and video calls, and file sharing, with connections established directly between participants rather than routed through intermediary servers. This design is intended to give users greater privacy, resilience, and control over their own data, since messages and files are transmitted and stored on user devices rather than in a central cloud. Typical use cases for Keet include confidential one-to-one conversations, private group chats for teams or communities, secure transfer of large files, and high-quality calls that benefit from direct connections between peers. Because the underlying technology does not depend on server capacity provisioned by the publisher, the product range also appeals to users concerned about censorship resistance, service outages, and third-party access to communications. Beyond its consumer-facing application, Holepunch's work reflects a broader category of developer-oriented peer-to-peer tooling, aimed at enabling other builders to create serverless applications for messaging, collaboration, data synchronization, and content distribution. Overall, the publisher's catalog centers on communication and data-sharing software that replaces traditional client-server models with fully distributed, encrypted peer-to-peer alternatives.
