Pick a spell, say what should happen, and get an import string. It produces real WeakAuras 2 export strings — the same Ace-serialised, deflated, base64 format the addon expects — so anything built here pastes straight into the game.
Ace3 serialisation, deflate via pako, base64 with WeakAuras' own alphabet. Not a mock — the string works.
Paste an existing aura and the wizard decodes it back into editable fields, so you can fork someone else's work.
Classic, TBC and Wrath spell lists plus a boss ability catalogue, so triggers are picked rather than typed.
Sign in and your auras follow you. Guilds can share a pack so the whole raid runs the same set.
