Coding Agents ComparisonBeta
Agents which operate on codebases end-to-end. They assist with or autonomously handle software development tasks (e.g., bug fix, feature, refactor, tests, migration) by understanding and producing concrete code changes (e.g., files, diffs, PRs) with direct or mediated access to repos/CLI/dev tools.

Landscape Summary
The table compares coding agents across four categories shown in the Category column: IDE extensions (e.g. GitHub Copilot, Cline, Continue, Roo Code, Amazon Q, Gemini Code Assist, Augment Code, Amp, Mistral Vibe), dedicated IDEs (Cursor, Windsurf, Zed, Google Antigravity, Kiro, Qoder, BLACKBOX), CLI tools (Claude Code, Aider, Codex, Gemini CLI, Goose, Warp 2.0, opencode, Qwen Code, Kimi CLI), and cloud platforms (Devin, OpenHands, Jules, Genie, Manus). Many tools span multiple categories — for example, Cursor and Codex each appear in three. Open-source and BYOM support are common, and pricing ranges from free open-source (Aider, Cline, Goose, Gemini CLI) through subscriptions up to $500/mo for cloud platforms.
Frequently asked questions
The table organizes agents into four categories: IDE extensions that add AI capabilities to existing editors (e.g. GitHub Copilot, Cline, Continue), dedicated IDEs built around AI (e.g. Cursor, Windsurf, Zed), CLI tools for terminal-based workflows (e.g. Claude Code, Aider, Gemini CLI), and cloud platforms that run tasks asynchronously in remote environments (e.g. Devin, OpenHands, Jules). Many tools span multiple categories.
Many tools support bring-your-own-model (BYOM), letting you connect custom models or hosted providers through API keys. Cline, Continue, Aider, Goose, Cursor, Zed, and similar tools offer full BYOM. GitHub Copilot, Windsurf, and others offer partial BYOM with a curated selection of models. Claude Code, Codex, Devin, and Amazon Q do not support BYOM and use the vendor's models only.
Yes. Many tools are open-source, including Cline, Continue, Aider, OpenHands, Goose, Zed, Roo Code, Gemini CLI, Mistral Vibe, opencode, Qwen Code, Kimi CLI, and BLACKBOX. Most charge only for LLM API calls. GitHub Copilot also has a free tier. Cloud platforms like Devin and Genie typically require subscriptions.
