The strongest GPT-native agent (CLI + cloud), good for delegated tasks with auto-test loops.
Our read

Why it ranks #4

A top CLI/cloud-agent recommendation across all three cited 2026 roundups, differentiated by one account spanning local Codex, the desktop app and delegated cloud tasks with isolated worktrees.

Here is the catch

plan limits vary with model and task complexity
cloud tasks require repository access and careful permissions
agent output still needs human architectural judgment

Does this well

strong integration between local work and cloud delegation
effective test-run-fix loops for scoped engineering tasks
good Git and multi-task workflow ergonomics
