Cheaper than Claude Code, compared fairly.

Claude Code starts at $20 a month with Claude Pro, so cheaper alternatives are Codex in ChatGPT Go ($8), Cursor Plus ($8, Grok models only), GitHub Copilot Pro ($10, with Claude Sonnet and Haiku models), Google Antigravity ($0) and the free, open-source opencode, Aider and Cline on a model you choose. If you already pay for ChatGPT, Copilot or Grok, Reason runs those plans in one coding agent and keeps going on your other connected accounts or Reason credits at a limit.

Run your existing plans in Reason

Open Reason on the web or the Mac app
Sign in at reasonmachines.com, or download the Reason app for macOS from reasonmachines.com/download. Both open the same Sessions. Sending work to Reason needs a Pro or Max plan.
Connect the plans you already pay for
In Settings › Models, under Subscriptions, connect ChatGPT (Plus, Pro or Business), Claude (Pro or Max), Grok (SuperGrok or X Premium+) or GitHub Copilot, and add API keys if you have them. Work on those accounts is billed by their provider, not in Reason credits.
Pick the model per task
In the composer, choose the model for each Session: a smaller model for routine fixes, a larger one for hard changes. Each Session shows the model and account it ran on.
Keep going at a limit
When the account a turn runs on hits its limit, Reason moves the turn to your other connected accounts for that provider, then to Reason credits if your workspace can pay, and says so in the conversation.

Cheaper than Claude Code, compared

Alternative	Price	What you give up
Codex in ChatGPT Go	$8 a month	Desktop app only, GPT-6 Luna at standard speed; Plus at $20 adds CLI, IDE and web
Cursor Plus	$8 a month	Grok models only; Claude and OpenAI models cost extra
GitHub Copilot Pro	$10 a month, 1,500 AI credits	Claude Sonnet 5.5 and Haiku 5.5 included; Opus and Fable need the $39 plan
Google Antigravity	$0 a month	Basic weekly rate limits
opencode	Free; OpenCode Go from $10	You bring the model; Go caps each model in dollars per month
Aider	Free	You bring the model; a terminal tool, no cloud agent
Cline	Free for individuals	You pay for inference; runs in your editor and terminal

From each vendor's pricing page or docs, checked Nov 2, 2026. For reference, Claude Pro is $20 a month ($17 billed annually), Max $100 and Ultra $200, and on the API Anthropic says Claude Code averages about $13 per developer per active day.

Cheaper isn't always worse, or better

On Artificial Analysis's Coding Agent Index v2.0, Claude Code on Opus 5.5 scores 62 and Codex on GPT-6 Astra 55, so the cheaper plan can mean a weaker model on hard tasks. On routine work, a smaller model on a cheaper plan often does the job.

Before switching, try lowering Claude Code's own cost: Anthropic's docs suggest Sonnet for most coding, clearing context between tasks, and lower effort for simple work.

What people on Reddit say

Two Reddit threads on the same question, read in full:

In an r/GithubCopilot thread from March 2026 comparing Claude Code's $20 plan with Copilot, several replies, the top one included, say Claude Pro's limits run out fast on Opus, while others say Copilot went further per dollar for long agent runs, back when it billed per request; Copilot now bills in AI credits. Several people pay for both: Copilot for bulk implementation, Claude Code for planning and debugging.

In an r/LocalLLaMA thread from April 2026 (over 150 replies) asking for a Claude Code-style agent for local models, many replies recommend opencode as the most plug-and-play option, several prefer pi for its small system prompt on consumer hardware, and others suggest Cline, Kilo Code or Roo Code in VS Code. A few point out that Claude Code itself can talk to a local model once its base URL is set.

Reason: all your AI subscriptions in one coding agent

Use the subscriptions you already pay for (ChatGPT, Claude, SuperGrok/X Premium+, Copilot) or your own API keys in one coding agent. Hit your limit and Reason keeps going on your other connected accounts or Reason credits.

Reason isn't the lowest-priced agent on this page: Pro is $50 a month with 1,250 credits a week, and Max is $200 with 5,000; a credit is $0.04. Work on your own connected subscriptions or API keys is billed by that provider, not in Reason credits, so you don't pay twice for a plan you already have.

On cost: in Reason's published benchmark on GPT-6 Astra at xhigh effort, with the same tasks and graders, Reason 1.1 scored 65.1 against Codex's 62.5 on Coding Agent Index v1.5, at 22% lower cost per solved task. That's Reason's benchmark of its own harness, with the runner published to reproduce it.

Questions

What is a cheaper alternative to Claude Code?

Codex in ChatGPT Go ($8 a month), Cursor Plus ($8, Grok models only), GitHub Copilot Pro ($10), Google Antigravity ($0), and the free, open-source opencode, Aider and Cline with a model you choose.

What is the best cheaper alternative to Claude Code?

For Claude models at a lower price, GitHub Copilot Pro at $10 includes Claude Sonnet 5.5 and Haiku 5.5. For a strong agent on a plan you may already have, Codex comes with ChatGPT Plus at $20. For free, opencode or Aider with a model of your choice.

Is there a free alternative to Claude Code?

Yes. opencode, Aider and Cline are free and open source, and Google Antigravity has a $0 plan. With an open-source agent you still pay your model provider unless you run a local model.

Can I use Claude models more cheaply?

Copilot Pro includes Claude Sonnet 5.5 and Haiku 5.5 in Copilot's own agents, and Anthropic's API prices Sonnet 5.5 at $2 and Haiku 5.5 at $0.10 per million input tokens, against $4 for Opus 5.5.

What happens in Reason when my plan hits its limit?

Hit your limit? Reason keeps going on your other connected accounts or Reason credits. The turn moves to your other connected accounts for the same provider, then to Reason credits if your workspace can pay.

Is Reason affiliated with these vendors?

No. Reason is built by Reason Machines and is not affiliated with or endorsed by Anthropic, OpenAI, GitHub, Anysphere, Google, Cognition or xAI. Prices and limits come from their own pages, linked under Sources.

Can I use Claude Code with cheaper models?

Only Claude models are supported: Anthropic's gateway docs say it doesn't support routing Claude Code to non-Claude models. To spend less inside Claude Code, use Sonnet or Haiku for routine work and clear context between tasks.

Is Claude Pro enough for Claude Code?

For light use. Pro ($20 a month, $17 billed annually) includes Claude Code within limits that reset every five hours and every week; Max ($100) gives 5x Pro's usage.

Is GitHub Copilot cheaper than Claude Code?

Its paid plans start lower: Copilot Pro is $10 a month, billed in AI credits, against $20 for Claude Pro.
