Ecko (discontinued)

Ecko is a Mastodon fork with many cool features, that Mastodon doesn't have.
It follows the Collective Code Construction Contract or C4 to e.g. add features that are deemed valuable by the community.
This is a difference from Mastodon, where Gargron decides which features Mastodon should have on his own even against the public opinion.

What features does Ecko have, that Mastodon doesn't?

The admin can change the following values in the config file:

• max toot length
• max poll options
• max poll answer length
• max profile metadata fields
• max length of “about me” text
• max number of pinned toots

The admin can also upload a favicon in the admin settings and import/export the instance blocklist.
Furthermore local toots are possible. Those are toots that can only be seen by people on the same instance.
