Devin vs Qwen: tracking usage on macOS

This is not an argument about which tool writes better code - that depends on your work, and anyone claiming otherwise is guessing. It is about something narrower and more answerable: how each one is metered, and what you can actually see while you use them.

How each is tracked

Devin uses your existing Devin CLI or app credential, and it keeps a local fallback, so a brief provider outage does not blank the reading.

Qwen uses an Alibaba console session cookie, and session cookies expire, so a flat line means re-authenticate rather than zero usage.

Why this matters if you run both

Running two tools means two places to check, two sets of limits, and two chances to be surprised mid-task. The cost is rarely the money - it is losing your thread because something stopped answering and you did not see it coming.

Watching both in one place

SessionWatcher shows Devin and Qwen together in the macOS menu bar. It reads and displays usage on your Mac; it does not read your code or your conversations. That boundary matters more when you are pointing one tool at two providers.

Per-tool detail is in the Devin tracker guide and the Qwen tracker guide.

No. Usage only, never code or conversation content.
