## Alternatives

1. [Plandex](https://www.isthereanytool.app/tool/plandex) — Underrated OSS CLI for big refactors when other agents choke on scale; tree-sitter project maps
2. [Aider](https://www.isthereanytool.app/tool/aider) — Long-time OSS favorite for precise refactors; map-reduce context; community notes slower core release cadence by 2026 with forks continuing
3. [Continue](https://www.isthereanytool.app/tool/continue) — Classic BYOK OSS IDE extension; 2026 coverage notes Cursor acquisition/archive risk—still widely referenced as the open control baseline
4. [Roo Code](https://www.isthereanytool.app/tool/roo-code) — Huge 2025 mindshare among VS Code agent users; 2026 reports of repo archive—still historically important and widely installed
5. [OpenCode](https://www.isthereanytool.app/tool/opencode) — Often cited as most-starred OSS Claude Code alternative; HN fixture for BYOK terminal agents
6. [Goose](https://www.isthereanytool.app/tool/goose) — Underrated extensible OSS agent; donated/community-governed narrative; strong MCP plugin story
7. [OpenHands (OpenDevin)](https://www.isthereanytool.app/tool/openhands-opendevin) — Leading OSS Devin-class framework; event-sourced SDK; research+self-host favorite
8. [Crush](https://www.isthereanytool.app/tool/crush) — HN darling for beautiful TUI UX from the Bubble Tea team; underrated vs Claude Code clones
9. [OpenAI Codex](https://www.isthereanytool.app/tool/openai-codex) — Apache-2.0 CLI with ChatGPT plan auth; strong Terminal-Bench showings; cloud+local split (CLI vs chatgpt.com/codex)
10. [Windsurf](https://www.isthereanytool.app/tool/windsurf) — Major AI IDE competitor to Cursor; ownership/branding shifted under Cognition/Devin Desktop narrative in 2026
11. [GitHub Copilot](https://www.isthereanytool.app/tool/github-copilot) — Broadest enterprise install base; Agent mode + CLI keep it competitive vs AI-native IDEs
12. [Copilot Agent](https://www.isthereanytool.app/tool/copilot-agent) — Bridges PM tickets to PRs without leaving GitHub; evolved from early Copilot Workspace experiments into agent features
