Libervia

Libervia provides a web‑based front‑end for the Salut à Toi communication platform, allowing users to interact with the service through a browser. It is designed to be self‑hosted, offering a free‑tier, subscription‑free experience under an AGPL‑3.0 license, and is marked as stable for production use. The project targets individuals or organizations that wish to run their own instance of the communication system while retaining full control over the software and its deployment.

A notable feature of the interface is the integration of Anubis, a proof‑of‑work challenge that mitigates automated scraping by requiring visitors to solve a lightweight computational puzzle. This mechanism is intended to deter large‑scale bots without noticeably affecting ordinary users, though it relies on modern JavaScript and may be blocked by extensions such as JShelter. By employing Anubis, Libervia aims to protect server resources while keeping the service accessible to legitimate browsers.
