Open-source coding agent alternatives

Looking to switch? Here's how agentty compares as an alternative to the popular coding agents.

• An open-source Cline alternative for the terminal (2026)Cline lives inside VS Code. agentty is terminal-first and editor-agnostic — a single native binary you can run anywhere, with multi-provider support and a sandbox by default.
• An open-source Continue alternative for the terminal (2026)Continue is an open-source IDE extension. agentty brings the same open, multi-provider approach to the terminal as a single native binary with a sandbox by default.
• An open-source Cursor alternative for the terminal (2026)Cursor is a polished AI IDE (a VS Code fork). agentty is terminal-first: no editor lock-in, a single native binary, multi-provider, and it plugs into Zed over ACP. Pick agentty if you live in the terminal and want provider freedom.
• An open-source Gemini CLI alternative (2026)The Gemini CLI ties you to Google's models. agentty is provider-agnostic — Claude, OpenAI, Groq, OpenRouter, Cerebras, or local Ollama — from a single native binary with a sandbox by default.
• An open-source OpenCode alternative (2026)Both are open-source terminal coding agents. agentty's edge is a single native C++26 binary (no runtime), millisecond cold start, built-in retrieval, and a sandbox by default.
• An open-source alternative to OpenAI Codex CLI (2026)The Codex CLI ties you to OpenAI. agentty runs against OpenAI too — plus Claude, Groq, OpenRouter, Cerebras, and local Ollama — from a single native binary with a sandbox by default.
• The best open-source Aider alternative (2026)Aider is a mature, Python-based pair-programming CLI with deep git integration. agentty is a single native binary with millisecond startup, a sandbox by default, and the same multi-provider freedom — no Python environment to manage.
• The best open-source Claude Code alternative (2026)agentty is a drop-in, open-source alternative to Claude Code: sign in with the same Claude Pro/Max plan, or point it at OpenAI, Groq, OpenRouter, Cerebras, or a local Ollama model — all from a single 16.7 MB native binary.
