Meta Muse Code alternatives

Meta launched Meta Muse Code on August 5, 2026, a terminal coding agent for macOS and Linux built on the new Muse Spark 1.2 model. It is a one-command install, ships default skills for planning and stress-testing tasks, and keeps a local event log so a crashed session can resume. It is also new, tied to a single model family, has no plugin ecosystem yet, and the cheap Contributor pricing tier is conditioned on Meta training on your prompts. If any of that is a dealbreaker, there are Meta Muse Code alternatives that already cover the same ground on Mac and Linux, with wider model support and workflows the community has been sanding down for a couple of years.

The seven picks below were used against real repositories: a Django backend refactor, a Rust CLI feature add, and a debugging pass on a legacy Node service. Each one runs in a terminal on macOS 14+ and mainstream Linux distros, and every pricing figure is what the vendor lists as of August 2026.

Why people look past Meta Muse Code

Muse Code is a credible entry, but the reasons developers on Hacker News and Reddit are shopping around are concrete.

Which one to pick, in one line each

The alternatives

1. Aider, best for git-native pair programming

Aider is a terminal coding CLI that treats git as the single source of truth. Every accepted edit becomes a commit with a generated message, so review is a normal git diff and rollback is git reset. The project is Apache 2.0, has 47.9k stars on GitHub, and works with Claude, GPT, Gemini, DeepSeek, Ollama, and LM Studio via BYO API key.

Where it falls short: Release cadence slowed in 2026. The last stable tag shipped in February, and the project is under lighter maintenance than OpenCode or Cursor CLI. There is no first-party GUI.

Pricing:

Migrating from Meta Muse Code: Install with pip install aider-chat, drop into any repo, and run aider. There is no session import from Muse Code, but Aider will index a large repo on first run and pick up context from the git history.

Download: aider.chat

Bottom line: The right pick if diff-first review and BYO models matter more than a slick UI.

2. Cursor CLI, best for Cursor IDE users on the terminal

Cursor CLI puts the Cursor agent inside your shell. Type agent and a slash-command menu exposes model selection, skills, built-in commands, and MCP servers. Prefixing a message with & fires off a cloud agent that opens its own branch and works asynchronously, so the local shell stays responsive.

Where it falls short: Locked to a Cursor account. The best models are gated behind Pro or above, and the free trial burns through requests quickly on a real repo. Cloud handoff needs your code in Cursor’s cloud, which some teams will not allow.

Pricing:

Migrating from Meta Muse Code: Install with the shell one-liner on the Cursor CLI page, sign in, and run cursor in a repo. Existing Meta Muse Code sessions do not transfer, but the /plan and /grill habits map to Cursor’s own slash commands.

Download: cursor.com/cli

Bottom line: The most polished option if you were already paying Cursor and want the same brain in the terminal.

3. Amp Code, best for enterprise monorepos

Amp Code is Sourcegraph’s autonomous coding agent, split out from Cody in 2026. It ships as a VS Code extension and a standalone CLI. Amp plans multi-step tasks, edits across a codebase, runs tests, reads the output, and iterates. The 200K token context lets it hold an entire service in memory in one pass.

Where it falls short: Best value shows up on large monorepos. On a small side project the free-tier ceilings arrive later than you would expect, but the Smart Mode upgrade is only worth it above a certain repo size. Enterprise procurement can be slow.

Pricing:

Migrating from Meta Muse Code: curl the install script from the Amp docs, authenticate against your Sourcegraph or standalone account, and point it at your repo. Amp can consume an existing Muse Code plan file if you paste it in as a prompt.

Download: ampcode.com

Bottom line: Best fit for teams whose main complaint about Muse Code is that Contributor pricing means training on their code.

4. Gemini CLI, best for a free Google-account tier

Gemini CLI now lives inside Google’s Antigravity CLI. Antigravity replaced the standalone Gemini CLI on May 19, 2026, and the free Google-login path for the old CLI ended June 18, 2026. In its new form, a personal Google account gets you Gemini 3, Google Search grounding, and a weekly compute cap at no cost.

Where it falls short: The free weekly quota is small on the personal tier and can be exhausted in a single afternoon of heavy agentic work. Enterprise controls, MCP support, and skill customization lag Claude Code and OpenCode.

Pricing:

Migrating from Meta Muse Code: Install Antigravity CLI, sign in, and run antigravity (the gemini shim still works). Slash commands overlap with Muse Code’s /plan in intent, not in syntax.

Download: antigravity.google

Bottom line: Hard to beat if a Google account and a modest weekly quota are enough for your workload.

5. OpenCode, best for model-agnostic open source

OpenCode is the most-starred open-source coding CLI in 2026. It is MIT-licensed, written in TypeScript, and runs a proper TUI in your terminal. The killer feature is model support: 75+ providers, including Anthropic, OpenAI, Google, Groq, Fireworks, Together, DeepSeek, and any OpenAI-compatible local endpoint via Ollama, vLLM, or LM Studio.

Where it falls short: No hosted service, so you provide the models and pay their providers. Skill and MCP ecosystems are growing but not as curated as Cursor’s.

Pricing:

Migrating from Meta Muse Code: Install with the shell script on the OpenCode site, drop into any repo, and point it at whichever provider you want. There is no state migration from Muse Code, but existing plan files paste in cleanly.

Download: opencode.ai

Bottom line: The lowest-risk open-source default if you want to keep every option open on models.

6. Cody, best for Sourcegraph enterprise deployments

Cody is now Sourcegraph’s conversational agent. Sourcegraph terminated the Cody Free and Cody Pro plans in July 2025, and the product is enterprise-only. It shines in shops that already run Sourcegraph for code search, because Cody can pull from indexed context across a large monorepo the way generic agents cannot.

Where it falls short: Costly and not available to individuals. If you were hoping for a free tier or a lightweight install, this is not the tool. Some multi-file autonomous work has moved to Amp.

Pricing:

Migrating from Meta Muse Code: Cody deploys through Sourcegraph enterprise onboarding, with SSO, admin config, and codebase indexing done up front. Individual Muse Code habits map to Cody chat and inline edit, not to a terminal-first CLI.

Download: sourcegraph.com/cody

Bottom line: Buy it if the Sourcegraph code graph is already in your stack. Skip it otherwise.

7. Continue, best for one assistant in the IDE and in scripts

Continue is a free, open-source assistant that runs as a VS Code and JetBrains extension, and now ships with a headless mode that can be scripted from a terminal or CI. It is model-agnostic, supports 100+ providers, and offers agentic edits that plan, edit multiple files, and run commands with approval.

Where it falls short: The terminal experience is less refined than a purpose-built CLI like Aider or OpenCode. Some teams find configuring providers and profiles more involved than they expected.

Pricing:

Migrating from Meta Muse Code: Install the Continue extension for your editor, add a provider profile, and run agent tasks either from the sidebar or a headless CLI command. Plan files from Muse Code paste in as prompts.

Download: continue.dev

Bottom line: The best pick if your team wants the same assistant experience in the IDE and in scripts, at no license cost.

How to choose between them

Start from three questions. Which models must you support? What are you allowed to send to a vendor? How much shell versus IDE time is realistic for the team.

If you must keep model choice open, OpenCode or Aider are the safe picks. OpenCode leads on activity and provider count. Aider leads on git ergonomics. If your team already pays for Cursor Pro, the CLI ships with the seat you have, and cloud handoff is genuinely useful. If your policy forbids training on your prompts, Amp Code is the cleanest posture, with OpenCode or Aider on self-hosted models as a runner-up. If cost is the only variable, Gemini CLI on Antigravity’s free tier goes furthest before you have to pay anything.

Stay on Meta Muse Code if the Contributor pricing is fine for you and Muse Spark 1.2 already handles your workload. It is fast, cheap on the Contributor tier, and the default skills are useful out of the box. Move if any of the constraints above (single-model, training toggle, no plugin ecosystem, beta gaps) turn into an active blocker.

FAQ

Is Meta Muse Code free? Muse Code the client is free to install. The Muse Spark 1.2 model is metered: Standard tier is $1.25 per million input tokens and $4.25 per million output tokens. Contributor tier is $0.10 in and $0.20 out per million, in exchange for letting Meta train on your prompts and completions.

What is the best open-source alternative to Meta Muse Code? For a terminal agent, OpenCode is the most-starred and most-active open-source pick in 2026. Aider is the strongest alternative if you value git-first workflows over a TUI. Both let you point at Claude, GPT, Gemini, or a local model via Ollama.

Does Meta Muse Code work on Windows? No. The beta ships for macOS and Linux only. If you are on Windows, use Cursor CLI, OpenCode, Aider, or Continue, all of which run on Windows today.

Can I use my own model with Meta Muse Code? Not right now. Muse Code is bound to Muse Spark 1.2. If BYO models matter, Aider, OpenCode, Continue, and Gemini CLI all support external model providers or local endpoints.

Which coding CLI is cheapest? Continue and OpenCode are free clients where the only cost is the model you route to. If you run a local model via Ollama, the running cost is effectively zero. Gemini CLI on Antigravity’s personal free tier is the cheapest hosted option before you hit its weekly quota.

Is Muse Code safe to use on private code? On the Standard tier, Meta states your prompts are not used for training. On the Contributor tier, they are. If your policy forbids third-party training on source code, use Amp Code, or self-host with OpenCode, Aider, or Continue on a local model.
