TERMINAL AGENTS

A new layer is forming around Claude Code, Codex, Copilot CLI, and local memory tools: the local coding agent workspace. It is not the model. It is the bench where agents get supervised.

A practical comparison of the two most capable terminal-native AI coding agents in 2026 - covering pricing, model flexibility, multi-agent workflows, and which one fits your team.

Codex CLI 0.129.0 added modal Vim editing in the composer. The feature is small, but it points at a bigger shift: terminal agents are becoming native engineering workbenches.

Terminal agents like Claude Code, Codex CLI, OpenCode, Copilot CLI, and DeepSeek-TUI are converging on the same runtime layer: permissions, sandboxing, rollback, diagnostics, subagents, receipts, and cost controls.
