Muse Code vs. Claude Code: price, benchmarks, and which one to use
Claude Code still edges Meta’s agent on most coding benchmarks, but Muse Code starts at $5 a month and its fastest runs finish in half the time. A side-by-side of plans, API prices, independent scores, privacy defaults, and how to switch between them.
The short answer
Claude Code, Anthropic’s coding agent, is still the stronger agent on most independent benchmarks, by a few points. Muse Code, Meta’s agent, is cheaper to start with, finishes its best runs faster, and has a different idea of how an agent should split up work. If you need the highest success rate on hard tasks and money isn’t the constraint, Claude Code is the safer pick. If you want a capable agent for $5–$15 a month, or you’re running many tasks in parallel, Muse Code is the better value — and since each can read the other’s project files and skills, trying both costs little.

| Free option | None | None — the free Claude plan doesn’t include Claude Code |
| Pay per token | Muse Spark 1.3 $1.25 / $4.25; Muse Wonder $4 / $20 per 1M input / output | Opus 5.5 $4 / $20; Sonnet 5.5 $2 / $10 per 1M input / output |
| Where it runs | Terminal on macOS, Linux, Windows | Terminal, VS Code and JetBrains extensions, desktop app, web |
| Training on your code | Plans start in Contributor mode (on) — turn it off in /settings |
You choose in Claude’s privacy settings; API usage isn’t used for training |
Prices are list prices as of October 25, 2026, from Meta’s and Anthropic’s pricing pages.
Price: where Muse Code wins clearly
The entry point is the biggest difference. Muse Code’s Everyday Usage plan costs $5 a month and covers roughly 10–50 prompts every five hours; High Usage at $15 gives five times that. Claude Code’s cheapest route is Claude Pro at $20 a month, and its usage is shared with your regular Claude chats.
At the top, the two converge. Muse Code’s Maximum Usage plan is $200 a month for 80 times the Everyday allowance, and it’s the cheapest way into Muse Wonder Full alongside the $50 Power plan. Anthropic’s Max plan starts at $100 a month, with a larger 20× tier above it.
On the API, the gap depends on the model. Muse Wonder and Claude Opus 5.5 have the same list price — $4 per million input tokens and $20 per million output tokens. Muse Spark 1.3, at $1.25 / $4.25, undercuts Sonnet 5.5, and if you accept Meta’s Contributor terms, muse-spark-1.3-contributor drops to $0.10 / $0.20, which nothing from Anthropic comes close to. The catch is that Contributor sessions may be used to train Meta’s models.
Benchmarks: Claude Code ahead, but closer than the price gap
Artificial Analysis runs both agents through the same coding-agent evaluation, each with its maker’s strongest model at maximum reasoning. Its scores, as published on October 25, 2026:
| Claude Code + Opus 5.5 | Muse Code + Muse Wonder Full | |
|---|---|---|
| Coding Agent Index | 62 | 59 |
| FrontierCode v1.1 | 56% | 49% |
| Terminal-Bench 4.0 | 63% | 59% |
| SWE-Atlas QnA | 66% | 69% |
| Time per task | 1.0 hours | 34.9 minutes |
Claude Code leads overall and on the two benchmarks that measure building and fixing software. Muse Code wins the codebase question-answering test and finishes its tasks in a little over half the time. The cheaper Muse configurations fall off more steeply: Muse Wonder scores 52 on the index at about $8 per task, and Muse Spark 1.3 scores 46 at about $3.91 per task — against $11.42 per task for Claude Code with Opus 5.5.
Meta’s own launch figures tell a friendlier story. Meta reports Muse Wonder Full at 79.0 on DeepSWE 1.1 against 74.2 for Claude Opus 5.5. Benchmarks run by the vendor, on harnesses the vendor chose, tend to favor the vendor, so weigh the independent numbers more heavily.
How they work differently
Muse Code is multi-agent by default. Every task gets a worker and a reviewer, and larger jobs fan out to persistent background agents, each in its own git worktree, so parallel changes don’t collide. A local event log records every model call and tool run, which makes sessions replayable and lets an interrupted run resume where it stopped. Our posts on background agents and worktrees go deeper.
Claude Code is more of a single strong agent that you can extend. It can spawn subagents for parallel work too, but its strengths are the model’s reliability on long, difficult edits and the breadth of places it runs — the terminal, VS Code, JetBrains IDEs, a desktop app, and the web.
Approvals and sandboxing exist in both. Muse Code starts in an Auto-review profile with an OS sandbox; its --yolo flag turns off both and is meant only for throwaway containers.
Privacy defaults
This is the difference most people miss. Muse Code subscriptions start in Contributor mode: in exchange for more usage, Meta can use your prompts and code to train future models. You can switch it off with /settings, at the cost of a smaller allowance. Don’t send confidential code with it on. On the API, the standard muse-spark-1.3 and muse-wonder-1.0 models are never used for training.
Anthropic asks consumer Claude users — including Pro and Max subscribers — to choose whether their chats and coding sessions can be used for training, and doesn’t train on API traffic by default.
Switching costs are low in both directions
The two tools can share a lot of your setup:
- Muse Code reads Claude Code’s files. It loads
CLAUDE.mdand.claude/CLAUDE.mdas project instructions, picks up skills from~/.claude/skillsand.claude/skills, andmuse skills import --from claudecopies them over. The/migratecommand imports Claude Code’s memory and MCP configuration. - Claude Code can run on Muse models. Meta documents pointing Claude Code at its Model API: set
ANTHROPIC_BASE_URLtohttps://api.meta.aiandANTHROPIC_AUTH_TOKENto your Model API key, then map every model alias tomuse-wonder-1.0ormuse-spark-1.3. Our docs have the full list of variables. You pay Meta per token for that, not through a Muse Code plan.
Which should you pick?
- Pick Claude Code if success rate on hard, multi-file changes matters more than price, if you want an IDE extension or desktop app, or if your team already pays for Claude.
- Pick Muse Code if you want a capable agent for $5–$15 a month, if you run many tasks in parallel and value the worktree isolation and replayable event log, or if you want the cheapest per-token option and can accept Contributor terms on non-sensitive code.
- Use both if you can: plenty of developers keep Claude Code for the hardest tasks and hand routine work to a cheaper agent. With shared
