Farewell Wiki is an online, collaboratively edited resource that describes itself as a pro-choice wiki focused on helping people make informed decisions about their lives. Its pages cover suicide-related topics, related publications and archives, and the history of pro-choice movements and wikis. The site also provides information about privacy and online security, including general material on VPNs and Tor, and links to discussion forums and peer-support spaces.

Additional sections address living options, financial planning, and resources for people seeking information about mental health and suicide. Farewell Wiki emphasizes user privacy and offers a Tor-accessible version of its site. Its content includes sensitive material about suicide and should be approached with care; it is not presented in the supplied text as a clinical service or substitute for professional help.

The wiki invites users to contribute and improve its pages, and its content is generally made available under a Creative Commons Attribution-ShareAlike license
