Community plugins and custom extensions are supported; the Basic plan allows three plugins. Basic is free forever and includes two projects, seven workflows, five filter presets, and one pipeline session at a time. The pricing note lists paid access from $20/user/mo, while the opened pricing page did not display prices for Individual, Team, or Enterprise.
