The free alternative to Claude Code
Same CLI agent loop. Different bill.
In short
- Freebuff is a free alternative to Claude Code with the same CLI-first agent loop.
- Claude Code Pro is $20/mo, Max is $200/mo. Freebuff is $0.
- You get 9 specialized subagents in the box: code-reviewer, browser-use, file-picker, and more.
- A model picker with MiMo 2.6 Flash (the default), GLM 5.3 Flash, DeepSeek V4.1 Flash, GPT-6 Luna, and more. Which models you see depends on your app and access level.
- Freebuff Desktop can also run Claude Code on your own Anthropic subscription, next to the free Freebuff harness.
Claude Code is, in my opinion, the best-designed CLI agent of the last two years. The taste is real. The feedback loop is right. I tell every new engineer to go read its docs even if they never plan to use it. The only thing standing between most people and shipping with it is the bill — $20/mo for Pro, $200/mo for Max. So the question keeps coming up: is there a free version that's actually good? Freebuff is our answer.
What “free Claude Code” actually means here
Freebuff is a CLI-first agent. You install it once with npm, cd into a repo, run freebuff, and you're talking to an agent that can plan, edit files, run shell commands, and review its own output. Same shape as claude. Different model menu, a richer subagent ecosystem in the box, and — the headline — nothing on your card. We genuinely think it's the closest 1:1 experience you can get to Claude Code for $0.
Feature-by-feature: Freebuff vs Claude Code
| Feature | Freebuff | Claude Code |
|---|---|---|
| Price | Free | $20/mo (Pro), $200/mo (Max) |
| Primary model | MiMo 2.6 Flash (default) / GLM 5.3 Flash / DeepSeek V4.1 Flash / GPT-6 Luna and more; Claude Code harness in Desktop with your own subscription | Claude 4.x family |
| Model choice per task | Yes via /model | Limited |
| Subagents bundled | 9 specialized | Generic delegation |
| Browser-use subagent | Built-in | MCP setup required |
| Slash command palette | /interview, /plan, /review, /deploy, more | Smaller default set |
| Available globally | Yes (limited mode covers VPNs + other countries) | Region-restricted |
What you keep
- The CLI feel. A real terminal interface, not a chat panel in an editor.
- Long-running tasks. Plan, edit, run, test, fix — the agent stays autonomous until the task is done.
- Permission prompts before destructive shell commands. Approve only what you want.
- Subagent delegation. Big tasks fan out to focused workers (file-picker, code-reviewer, browser-use) and come back with verified results.
What you get that Claude Code does not have
- Choice of frontier model. Switch models mid-conversation. Each task can use the model best suited to it.
- Built-in browser-use subagent. The agent can drive a real browser to verify the app it just shipped.
- Your own subscriptions, in Desktop. Freebuff Desktop runs threads on the Freebuff harness for free, or on the Claude Code or Codex harness with your own Anthropic or ChatGPT subscription.
- Slash commands shaped around shipping.

When Claude Code is still the better pick
If your team is standardized on Anthropic models, has bought into the Claude Sonnet/Opus style of reasoning, and the $20–$200/mo is rounding error, Claude Code is a fantastic product. Freebuff is for everyone else: people who want the same loop without the subscription, or want to choose their model per task.
