Concrete's marketplace is small enough to know every add-on in it, so we do. This directory lists the ones we would install, what they cost, and what state they are in. When something looks abandoned, the entry says so.

Omissions
Whale-branded add-ons are gone from the relaunched marketplace. Simple Gallery is listed elsewhere but we could not verify its developer or recency. The stale Community Store gateways are flagged above rather than dropped, because they still work if you pin them and you should know what you are signing up for.
The community forum
The forums at forums.concretecms.org are where the Concrete community talks. There is no Slack and no Discord, by deliberate decision. Search there first; the useful threads are long.
