Translations:F.A.Q. - Frequently Asked Questions/39/en

Most servers will have the same features and limits. Some may have higher limits for e.g. characters in a post (climatejustice.social has 5.000 instead of the usual 500).
The limit for poll options or the number of bio-links may have been adjusted by the admins. But each code change may create problems at every Mastodon update, thus most servers run with the original settings.
As of right now, there are no listings of Mastodon instances that also include information about deviations concerning features or limits. And instances commonly also do not advertise them on their "/about" pages. Asking around before joining a server, is currently the only way to figure this out.
