Clicks and types on websites for you. | Kuaishou's video model. The surprise standout. |

| Best for | Ops teams, marketers, anyone building dashboards from multiple sources. | Engineering teams already using Linear + OpenAI Codex who want to stop babysitting agent sessions and instead let the issue tracker drive autonomous coding at scale. | Power users willing to pay $200/mo for a browser bot. | Anyone who wants top-tier video quality for less. |

| Kai's verdict | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | 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.) | B-tier. Still early. Manus is more flexible for less money. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. |
