| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | Symphony is the most architecturally serious 'issue tracker as control plane' approach yet — 15K GitHub stars in weeks confirms the idea resonates — but it's still a rough, self-hosted engineering preview that demands Elixir chops and a Linear-only workflow. (Verdict pending Phi's full review.) | A-tier for data teams. S-tier if you already live in SQL + Python. |
