Devx Review 2026: A fast terminal AI coding agent for Termux, Windows, macOS, and Linux
Devx is an ultra-fast terminal AI coding agent with dual PLAN/AGENT modes, multimodal vision, a live web server, self-healing diagnostics, and snapshot rollback. Runs on Android Termux, Windows, macOS, and Linux.
What Devx Does
Devx (Termux-Dev) is an autonomous AI pair-programmer and vibe-coding terminal agent built for Android Termux, Windows, macOS, and Linux. It toggles between a safe PLAN mode (architect and requirements planner) and an AGENT mode (autonomous file edits, terminal commands, auto-installer), with multimodal vision, a built-in live web server, diagnostics, and rollback.
Key Features
- Dual-brain PLAN / AGENT modes with one-click plan approval (
[π Go / βοΈ Other]) - Multimodal vision β paste screenshots from clipboard with smart duplicate badges
- Self-healing diagnostics for TypeScript, JavaScript, Python, and Rust, with auto-fix before finishing a turn
- Snapshot rollback via
/undoreverts the last AI turn cleanly - Universal providers: OpenRouter, Gemini, DeepSeek, Groq, Mistral, OpenAI, Anthropic, Ollama, LM Studio
- Project memory bank (
.devx/memory.md) and rich slash commands (/serve,/commit,/diff)
Who Should Use Devx
Developers who live in the terminal β especially on Android via Termux β and anyone who wants a lightweight, provider-agnostic coding agent without a heavy IDE. Good for quick fixes, CI one-shot runs, and mobile coding.
