Canonical: https://www.isthereanytool.app/alternatives/gemini-cli

Gemini CLI is filed as open source / plan-tied Coding Agents & AI IDEs software, best for open Gemini terminal agent (pre/alongside Antigravity). Major OSS Google CLI agent; still relevant for enterprise Code Assist licenses amid Antigravity transition. All 12 picks sit on our Coding Agents & AI IDEs shelf with overlapping use cases. This page lists 12 neighbors we actually store beside Gemini CLI — not vendor rankings.

## Alternatives

1. [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)
2. [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
3. [Cline](https://www.isthereanytool.app/tool/cline) — Leading in-editor autonomous agent; MCP; multi-provider; natural landing spot after Roo Code archive chatter. Desktop expands Cline beyond the IDE for open-weight workflows.
4. [OpenCode](https://www.isthereanytool.app/tool/opencode) — Often cited as most-starred OSS Claude Code alternative; HN fixture for BYOK terminal agents
5. [Goose](https://www.isthereanytool.app/tool/goose) — Underrated extensible OSS agent; donated/community-governed narrative; strong MCP plugin story
6. [Amp](https://www.isthereanytool.app/tool/amp) — Code-graph DNA from Sourcegraph; deliberately no BYOK knobs—max capability, usage-priced
7. [Google Antigravity](https://www.isthereanytool.app/tool/google-antigravity) — Successor narrative to Gemini CLI for agentic Google coding; multi-surface same backend
8. [Zed AI](https://www.isthereanytool.app/tool/zed-ai) — Performance-first OSS editor; ACP pioneer wiring Claude Code/other agents into a non-VS-Code shell
9. [Kilo Code](https://www.isthereanytool.app/tool/kilo-code) — Rising OSS agent (OpenCode-fork CLI lineage) praised in 2026 'best agent' tables
10. [Crush](https://www.isthereanytool.app/tool/crush) — HN darling for beautiful TUI UX from the Bubble Tea team; underrated vs Claude Code clones
11. [Mistral Vibe](https://www.isthereanytool.app/tool/mistral-vibe) — European frontier-lab full coding agent stack; pairs Codestral/Medium models with terminal+IDE+web surfaces
12. [Claurst](https://www.isthereanytool.app/tool/claurst) — Underrated 2026 Rust Claude Code alternative on HN/GitHub; ACP-ready for Zed and friends
