## What to watch for

- **OpenCode**: The web UI's server-URL-override feature and local HTTP server have a real, disclosed 2026 security history (two now-patched advisories), so running it on a shared or untrusted network needs care.
- **Muse Code**: Three observer agents (memory, skill, goal) run by default and add their own billed model calls on top of the main session, switchable in settings.json under runtime_capabilities.
- **Aider**: Usage numbers like 44K GitHub stars, 6.8M installs, 15B tokens/week and the 88% 'Singularity' metric are self-reported on aider.chat; independent verification of these figures was not found.
- **Google Antigravity CLI**: Not yet open source. No LICENSE file in its public GitHub repo, unlike the Apache-2.0 Gemini CLI it replaces, and Google has not confirmed whether that will change.
- **Claude Code**: Terminal-first. There is no full graphical editor for those who prefer point-and-click.
- **zot**: No GUI, terminal-first by design, unlike GUI-based rivals such as Juggler.
- **Codex CLI**: Free-tier access is explicitly limited, regular use effectively requires at least a $20/month Plus plan or a separate API key.

The ones people open most here come first, then the closest matches.

## Shortlist

### 1. OpenCode

Open source AI coding agent for the terminal, desktop, IDE and browser, with any LLM provider.

**Where it improves on Gemini CLI:**
- [Runs autonomously: yes — An auto-approve mode clears every permission prompt that is not explicitly denied, and non-interactive runs plus scheduled GitHub workflows execute with no one watching.](https://opencode.ai/docs/permissions/)
- [Claude: yes — Claude models are available both through an Anthropic API key and through the vendor's own gateway, and a Claude subscription can be connected directly.](https://opencode.ai/)
- [GPT: yes — GPT models are listed on the vendor's own gateway with per-token prices, and a ChatGPT Plus or Pro login can be used instead of an API key.](https://opencode.ai/)

**Trade-offs against Gemini CLI:**
- [Whole-codebase work: partial — Built for multi-step work across a repository through subagents and LSP loading, but the docs describe no repository-wide index or migration guarantee, so scale rests on agent orchestration.](https://opencode.ai/docs/agents/)

[View OpenCode](https://theagentsindex.com/opencode)

### 2. Muse Code

Meta's terminal and CI coding agent, built on the Muse Spark model.

**Where it improves on Gemini CLI:**
- [Runs autonomously: yes — A headless run takes one prompt to completion with approvals disabled, and session goals keep the runtime queueing follow-up work until the objective is met.](https://dev.meta.ai/docs/muse-code/extending)
- [Pooled budget: yes — Rate and token quotas are shared across the whole team rather than allocated per key, so multiple developers draw on one pool on pay-as-you-go.](https://dev.meta.ai/docs/pricing-rate-limits)
- [Opt out of training: yes — Standard-tier models are contractually excluded from training, and the discounted contributor models that do train on your content are opt-in by model id and can be left behind by upgrading.](https://dev.meta.ai/legal/commitments)

**Trade-offs against Gemini CLI:**
- [Whole-codebase work: partial — It splits a large job across parallel subagents with optional Git worktree isolation, which fits a repository-wide migration, but the vendor documents no repository indexing and caps a tree at eight concurrent agents by default.](https://dev.meta.ai/docs/muse-code/extending)
- [In your editor: no — The vendor describes exactly two run surfaces, interactive terminal and headless, with no editor or IDE extension mentioned anywhere in the Muse Code documentation set.](https://dev.meta.ai/docs/muse-code)
- [Self-hosted: no — The binary runs locally but every turn calls Meta's hosted model and refuses to start without a Meta credential, so inference cannot be run on your own infrastructure.](https://dev.meta.ai/docs/muse-code/auth)

### 3. Aider

Open-source terminal AI pair programmer that edits files in your local git repo and commits the changes.

**Where it improves on Gemini CLI:**
- [Claude: yes — Anthropic Claude is named as one of the models aider works best with, and the quick-start shows launching it with an Anthropic key.](https://aider.chat/docs/llms.html)
- [GPT: yes — OpenAI models are listed among the best-supported engines and have their own provider page, with the entry command shown using an OpenAI key.](https://aider.chat/)
- [Open models: yes — Local open-weight models are explicitly supported through Ollama, LM Studio and any OpenAI-compatible endpoint, so inference can stay on your own hardware.](https://aider.chat/docs/llms.html)

**Trade-offs against Gemini CLI:**
- [Whole-codebase work: partial — A ranked map of the whole git repo gives it repository-wide context, but the vendor warns performance is not optimised for very large monorepos and only one repo can be open at a time.](https://aider.chat/docs/faq.html)
- [Ships it: no — The documented end of the loop is a git commit in your local repo; no page on the site describes deploying, pushing a release or publishing to an environment.](https://aider.chat/)
- [Multi-agent: partial — Architect mode splits one task across two model roles, an architect that proposes and an editor that writes the edits, which is role separation rather than several agents coordinating freely.](https://aider.chat/docs/usage/modes.html)

### 4. Google Antigravity CLI

Terminal agent (agy) that runs Google Antigravity coding agents and parallel subagents.

**Where it improves on Gemini CLI:**
- [Claude: partial — Claude Opus and Sonnet 5.5 are selectable, but only on paid Google AI Pro, Ultra or Enterprise; the free tier's Claude 4.6 entries are flagged for removal.](https://antigravity.google/docs/models)
- [GPT: partial — No OpenAI GPT model is offered; the only GPT-named entry is the open-weight GPT-OSS-120b, which the table marks for removal and excludes from Enterprise.](https://antigravity.google/docs/models)
- [Open models: partial — One open-weight model, GPT-OSS-120b, is selectable on consumer plans, and the same table dates its removal, leaving no standing open-weight option.](https://antigravity.google/docs/models)

**Trade-offs against Gemini CLI:**
- [Agent permissions: partial — A three-list allow/ask/deny engine governs files, commands, URLs and MCP tools, but unconfigured actions default to asking, so broad autonomy requires rules you write yourself.](https://antigravity.google/docs/permissions)
- [In your editor: no — This product is the terminal surface by definition; editor use is sold as separate Antigravity IDE extensions rather than a feature of the CLI.](https://antigravity.google/product/antigravity-cli)
- [Self-hosted: no — The binary runs locally but inference does not: the vendor states plainly that no bring-your-own-endpoint option exists, so model traffic leaves for Google endpoints.](https://antigravity.google/docs/plans)

### 5. Claude Code

Agentic coding tool from Anthropic that edits your codebase, runs commands, and opens pull requests.

**Where it improves on Gemini CLI:**
- [Runs autonomously: yes — Auto mode has a classifier approve tool calls instead of a person; routines and background sessions run unattended, including in the cloud.](https://code.claude.com/docs/en/permissions)
- [Claude: yes — Claude is the only model family: Fable, Opus, Sonnet and Haiku aliases, resolved per provider.](https://code.claude.com/docs/en/model-config)
- [In your pipeline: yes — GitHub Actions and GitLab CI/CD run it in your own pipelines; a managed GitHub PR reviewer exists on Team and Enterprise.](https://code.claude.com/docs/en/overview)

**Trade-offs against Gemini CLI:**
- [Self-hosted: partial — The CLI executes on your own machine, and cloud sessions can run on your runners in public beta on Team and Enterprise; inference always goes to Anthropic or a cloud provider.](https://code.claude.com/docs/en/self-hosted-environments)
- [Open source: no — The vendor's own repository carries an all-rights-reserved licence; the public repo holds plugins, docs and the issue tracker, not the CLI source.](https://github.com/anthropics/claude-code/blob/main/LICENSE.md)
- [Free tier: no — The $0 Free Claude plan does not include Claude Code at all: the pricing page's own plan comparison marks the Claude Code row No for Free and Yes from Pro upward, and the FAQ says it is included in all paid plans, so the cheapest way in is the $20 monthly Pro subscription rather than a standing free tier or a published trial.](https://claude.com/pricing)

### 6. zot

Single-binary terminal coding agent harness in Go, with 30+ model providers and any-language extensions.

**Where it improves on Gemini CLI:**
- [Runs autonomously: yes — Confirmation is opt-in rather than default, and the headless modes deliberately run tools without asking so pipelines complete unattended, bounded only by a step cap.](https://www.zot.sh/docs/tool-gate)
- [Claude: yes — Anthropic is a first-class provider reachable either with an API key or by logging in with an existing Claude Pro or Max subscription through the OAuth flow.](https://www.zot.sh/docs/providers)
- [GPT: yes — OpenAI is supported through both the Chat Completions and Responses APIs with a key, and through a ChatGPT Plus or Pro subscription via the Codex login flow.](https://www.zot.sh/docs/providers)

**Trade-offs against Gemini CLI:**
- [Debugs and fixes: partial — No dedicated debugging feature; the vendor names failure investigation only as an example of a task you can hand a background sub-agent, which then edits the same working directory.](https://github.com/patriceckhart/zot)
- [Whole-codebase work: partial — It works across a whole working directory with recursive glob search and a canned whole-project reading pass, but there is no repository index; large work depends on the model window and automatic compaction.](https://github.com/patriceckhart/zot/blob/main/README.md)
- [Agent permissions: partial — By default the agent acts without asking; per-call confirmation is a flag you must pass, it only exists in the interactive TUI, and the jail sandbox is described as a guardrail rather than a boundary.](https://www.zot.sh/docs/tool-gate)

### 7. Codex CLI

OpenAI's terminal coding agent for inspecting, editing and running repository code from the shell.

**Where it improves on Gemini CLI:**
- [Runs autonomously: yes — Approval prompts can be switched off entirely, including a no-sandbox full-access mode.](https://learn.chatgpt.com/docs/agent-approvals-security)
- [GPT: yes — GPT-5.6 Sol, Terra and Luna are all marked available in Codex CLI, selected with --model.](https://learn.chatgpt.com/docs/models)
- [Open models: yes — --oss runs Codex against a local Ollama or LM Studio provider.](https://learn.chatgpt.com/docs/config-file/config-advanced)

**Trade-offs against Gemini CLI:**
- [Whole-codebase work: partial — Documented for repository-wide exploration and multi-step plans; the vendor states no repo-wide migration guarantee.](https://learn.chatgpt.com/docs/agent-configuration/subagents)
- [Self-hosted: partial — The agent binary runs on your machine or runner; inference is OpenAI-hosted unless you route it through your own AWS Bedrock account.](https://learn.chatgpt.com/docs/amazon-bedrock)

[View Codex CLI](https://theagentsindex.com/codex-cli)

### 8. GitHub Copilot CLI

GitHub's agentic coding CLI that plans, edits, runs code and works with issues and pull requests.

**Where it improves on Gemini CLI:**
- [Ships it: yes — It goes past the diff: it commits locally, opens pull requests on GitHub.com on your behalf, and can merge or close them.](https://docs.github.com/en/copilot/concepts/copilot-surfaces/copilot-cli)
- [Claude: yes — Claude is the default model in the CLI and further Claude versions are selectable with the /model command.](https://github.com/github/copilot-cli)
- [GPT: yes — OpenAI GPT models are offered alongside Claude in the model picker, and GitHub names OpenAI as one of its providers.](https://github.com/github/copilot-cli)

**Trade-offs against Gemini CLI:**
- [Self-hosted: no — The agent is a client for GitHub's hosted service and GitHub states Copilot is not available on its self-managed server product.](https://docs.github.com/en/copilot/get-started/plans)
