UltraGuest vs Atabook

Atabook and UltraGuest are both free guestbook services that host the guestbook as a page on their own servers. Atabook is the newer of the two: its site carries a copyright line from 2024, and a thread on the 32-Bit Cafe forum from May 2024 describes its release as a response to the closure of 123Guestbook. UltraGuest has hosted guestbooks since 2003. Everything said about Atabook here was read on its own website (home page, Features, Terms, Privacy and a live guestbook) in September 2026 and is reported without judgement; things change, so please check atabook.org for current details. UltraGuest is not affiliated with Atabook.

What they have in common

Both are free. Both give you a guestbook at the service's own address that you link to. Both can hold new messages for review, let you edit or delete any message, block IP addresses, e-mail you about new messages and let you delete your own account. Neither shows advertising today: UltraGuest has none, and Atabook's features page says it shows none right now, with a "no ads guarantee" among the benefits of its paid Supporter plan.

Which one is for you?

If you want the guest e-mailed when you reply, ask custom questions or offer a formatting toolbar, Atabook lists all of those, and its no-ads guarantee, custom CSS, your own domain and several guestbooks come with its Supporter plan. If you want no advertising on any account, custom CSS and an official embed included, messages that cannot carry links and a track record going back to 2003, that is UltraGuest. Both are free to try; on Neocities or Nekoweb, see guestbooks for Neocities.
