Changes to Via, Hypothesis' proxy server for annotation (web.hypothes.is)

Hypothesis announced significant changes to Via, its proxy server for web annotations, transitioning from an open to a closed model to enhance security and compliance. The original open proxy allowed users to view annotated content without an account, but the move to a closed system, initiated in 2021, was driven by the need to filter out malicious activity and ensure that only legitimate, annotatable websites were accessible. This strategy has been coupled with a growth in alternative access methods, such as their Chrome extension and Bookmarklet, as well as robust integration into educational platforms through their LMS app, which now accounts for most of Hypothesis' usage among students. Going forward, Via will be restricted to core websites approved through partnerships with Hypothesis, allowing for improved platform security and reliability while facilitating future development initiatives. Notably, the code for Via remains open source, inviting others to operate the service on their domains, which encourages collaboration within the community. These changes, set to take effect on February 2, 2026, signify Hypothesis' commitment to fostering a secure and supportive environment for annotation, emphasizing both user privacy and educational engagement.
