@wongsyrone A pull request for the website?

[Mygod]

@wongsyrone Thanks but what I meant is having a table for different ports of shadowsocks.

[Mygod]

See that table I mentioned. It should include TCP Fast Open, etc.

[Mygod]

That's a table, not a feature comparison table though.

I think using the Wiki page is a good idea, since it allows the developers of different SS implementations to update the features of their own software. The shadowsocks.org website would then have a link to the Wiki page, similar to what's proposed in #51.

[riobard]

We should probably define a standard set of features first, and allow each implementation to define their extensions.

[riobard]

I've added a page to list current implementations under active maintenance with feature comparison here https://github.com/shadowsocks/shadowsocks-org/wiki/Implementations

Please leave a comment for any missing features.

what is "Redirect mode"

[ccsexyz]

Netfilter TCP redirect

[riobard]

We should have a brief explanation of each feature, or at least links to its spec. Anyone knows what's the spec for multiuser and management API? I just copied that from the original wiki.

[riobard]

Also, should we have a section for 3rd-party implementations and clients?

From the original Wiki of Shadowsocks in python, maybe outdated:

https://github.com/shadowsocks/shadowsocks/wiki/Configure-Multiple-Users

https://github.com/shadowsocks/shadowsocks/wiki/Manage-Multiple-Users

[riobard]

@hellofwy Nice!

[Mygod]

I think it's better to combine these two tables and add "Server mode" row.

[riobard]

@Mygod I was thinking about the same until I realize the features for clients are very different from those of servers.

[Mygod]

Hmm... On second thought, we should add shadowsocks-libev (etc.) and features like TFO, UDP relay to clients table then.

[Mygod]

Also redirect/tunnel mode should be moved to clients.

[riobard]

Yeah, it's a mess right now. Haven't found a better way to organize so I just followed the format of the original wiki page.
