Verdicts
Praised for
  • Can run and switch between several agents (built-in and ACP external agents) in one editor window
  • Parallel agent threads with worktree isolation are praised by users moving from single-thread agent workflows
  • Fast, lightweight editor that users keep even when they run agents elsewhere
  • Free bring-your-own-key use and external agents on the $0 plan
  • Generous usage within ChatGPT subscriptions compared with rivals, per many community comments (HN)
  • Strong Terminal-Bench 2.0 result: rank 4 of 43 harnesses
  • Safe-by-default local sandbox and approval model (docs)
  • Delegation and review workflow in the app praised by reviewers (Every; Composio)
Criticised for
  • Agent UI and parallel-agent layout described as confusing by several users after the April 2026 changes
  • Built-in agent seen by some reviewers and users as less capable or less turnkey than Cursor, Claude Code or OpenCode
  • ACP-hosted external agents reported as buggy or limited (buffer not refreshing, lost LSP access, never-ending runs)
  • Diff/code-review tooling for reviewing agent output considered insufficient by some users
  • Usage-limit and rate-limit changes cause sharp complaints (GitHub issue #28879 with 364 upvotes)
  • Reported bugs with serious side effects, e.g. $HOME deletion in full-access mode (Simon Willison, July 2026) and excessive SSD writes from logs
  • Weak front-end/UI output reported by some users (r/codex)
