Coding Agents Comparison
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.
To compare language models see our model benchmarks.

Landscape Summary
The table compares coding agents across four categories shown in the Category column: IDE extensions (e.g. GitHub Copilot, Cline, Gemini Code Assist, Augment Code, Amp, Mistral Vibe), dedicated IDEs (Cursor, Devin, Zed, Google Antigravity, Kiro, Qoder, BLACKBOX), CLI tools (Claude Code, Aider, Codex, Goose, Warp 2.0, opencode, Qwen Code, Kimi CLI), and cloud platforms (Devin, OpenHands, Jules, Cosine, 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) through subscriptions up to $200/mo for most individual plans.
Frequently Asked Questions
The table organizes agents into four categories: IDE extensions that add AI capabilities to existing editors (e.g. GitHub Copilot, Cline), dedicated IDEs built around AI (e.g. Cursor, Devin, Zed), CLI tools for terminal-based workflows (e.g. Claude Code, Aider), 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, Aider, Goose, Cursor, Zed, and similar tools offer full BYOM. GitHub Copilot and Google Antigravity expose curated model selections; Qoder supports custom providers, and BLACKBOX lets enterprise customers use their own provider accounts. Claude Code, Codex, Devin, and Kiro use vendor-hosted models only.
Yes. Fully open-source tools include Cline, Aider, OpenHands, Goose, Zed, Mistral Vibe, opencode, Qwen Code, and Kimi CLI. Codex, Warp, and BLACKBOX have partially open-source components. Costs vary: some self-hosted tools require only model inference, while hosted services may charge subscriptions or usage fees. GitHub Copilot also has a free tier.
