Details: why these tools, the same Turkish-language task trial, sources

Try it free

  • Gemini CLI: The only official agent that gives a free quota in the terminal with a personal Google account: the README says "60 requests/min and 1,000 requests/day". First step: Install with `npm install -g @google/gemini-cli`, type `gemini` in an empty test folder and sign in with your personal Google account; write the project rules in GEMINI.md.
  • Cursor: If you want an agent inside a code editor, the Hobby plan opens without a card ("No credit card required", "Limited Agent requests"). First step: Download from cursor.com, sign in on Hobby, turn on Privacy mode in Settings (while it's on, code data isn't used for training), then open a test folder and write your first task in the Agent panel.
  • OpenAI Codex CLI: If you have a ChatGPT account you can use Codex at no extra cost; but for Free/Go the pricing page lists only the desktop app ("in the desktop app, subject to rollout"). First step: Turn on Codex mode in the ChatGPT desktop app and check your quota with a small task; the pricing page lists the CLI and IDE extension for Plus and above.
  • Google Antigravity: The tool most often compared with Claude Code on a Turkish forum (12 threads among R10's coding-starter topics); the individual plan is "$0/month" with unlimited Tab completions. First step: Install Antigravity 2.0 from antigravity.google (or the CLI with `irm https://antigravity.google/cli/install.ps1 | iex`), sign in with your personal Google account and turn off data collection in Settings.

First payment: one subscription

  • Claude Code: The most asked-about and most recommended agent on forums (1,124 posts in English); the Pro plan includes Claude Code, the free plan doesn't. First step: Install in PowerShell with `irm https://claude.ai/install.ps1 | iex` (no admin needed, Git for Windows recommended), then in the project folder run `claude` → sign in through the browser → create CLAUDE.md with `/init`.
  • OpenAI Codex CLI: If you already pay for ChatGPT Plus you don't need a second subscription: Plus includes "Codex on the web, in the CLI, in the IDE extension". First step: Install with `npm install -g @openai/codex`, run `codex` → "Sign in with ChatGPT", and track your remaining quota in the session with `/status`.
  • Cursor: For anyone who'd rather work in an editor than a terminal, Individual (Pro) at $20/month unlocks MCP, skill and hook support plus cloud agents. First step: Upgrade only through cursor.com (third-party resellers are unauthorized), and keep Privacy mode on.
  • Google Antigravity: If you're buying Google AI Pro for Gemini anyway, it also raises your agent limit in Antigravity; the only option here billed in local currency in Turkey. First step: Buy Google AI Pro through Google One, sign in to Antigravity with the same account and check your quota with `/usage`.
  • Context7: Brings up-to-date library documentation to the agent to cut down on invented or outdated API code; among the plugins recommended on forums, Context7 appears in 16 threads/83 comments. First step: Get a free API key from context7.com and add it with `claude mcp add --scope user --header "Authorization: Bearer API_KEY" --transport http context7 https://mcp.context7.com/mcp`.
  • Playwright MCP: Lets the agent open the page it built in a browser and check it by clicking through; one of the most recommended MCPs on forums (19 threads/84 comments), from Microsoft's official repository. First step: Add it with `claude mcp add playwright npx @playwright/mcp@0.0.82`; don't use a persistent browser profile with logged-in accounts.
  • Frontend Design: If you're building a site or interface, the official Anthropic skill that reduces the template look that screams "made by AI"; it has no network access or scripts. First step: Inside Claude Code, type `/plugin install frontend-design@claude-plugins-official`; the official marketplace is added automatically in the first session.

As you grow: more quota, workflows

  • Claude Code: The Max plan gives 5 or 20 times Pro's usage; for people hitting the weekly limit in long agent sessions. First step: Switch to Max 5x at claude.com/pricing ($100 + tax on the web); watch for a week whether you still hit the weekly limit.
  • OpenAI Codex CLI: ChatGPT Pro tiers at $100/$200/$500 give longer Codex sessions and a higher quota. First step: First try extra usage on Plus with ChatGPT credits (Flexibly extend usage); if you keep running over, move to Pro 100.
  • Superpowers: The most recommended workflow kit that enforces brainstorm → plan → test-first implementation → review (19 threads on forums); not for day one, but once plan mode has become a habit. First step: Install with `/plugin install superpowers@claude-plugins-official`; turn off telemetry with `SUPERPOWERS_DISABLE_TELEMETRY` and keep in mind that it adds context to every session.
  • GitHub MCP Server: Connects issues, PRs and Actions to the agent; it pays off as the team and repository grow. First step: Create a fine-grained GitHub token limited to the repositories you need and read access, then add it with `claude mcp add --transport http github https://api.githubcopilot.com/mcp -H "Authorization: Bearer TOKEN"`.
  • Chrome DevTools MCP: Lets the agent read performance traces, network and console errors; for when Playwright isn't enough. First step: Add it with `claude mcp add chrome-devtools --scope user npx chrome-devtools-mcp@1.10.1 -- --no-usage-statistics` and use it with a separate Chrome profile.
  • Anthropic Agent Skills: Official document skills that produce Word/PDF/PowerPoint/Excel files, plus a skill-writing template; for when you start having it do document work beyond code. First step: `/plugin marketplace add anthropics/skills`, then `/plugin install document-skills@anthropic-agent-skills`; the document skills need LibreOffice and Python installed locally.

The same task in Turkish

In this folder, build a single-file Turkish-language web page (index.html): "Monthly AI subscription calculator". The user enters the monthly price in US dollars and the dollar exchange rate; the page shows the Turkish lira equivalent, the amount with 20% VAT added and the 12-month total including VAT. Numbers should use Turkish formatting (period as the thousands separator, comma for decimals, e.g. 1.180,74). Don't use any external library or internet connection; keep all CSS and JavaScript in the same file. Before you start coding, write a short plan and wait for my approval. When you're done, add an AGENTS.md file to this folder with 3 rules to follow in this project.

What a good answer should include: Presents a plan first and asks for approval; a single index.html with no external links; with $20 and a rate of 49.1976 it shows 983.95 lira, 1,180.74 lira including VAT and 14,168.91 lira for 12 months; all interface text is in Turkish; an error message on invalid input (empty/negative); a 3-item AGENTS.md is created. Note: the number of sessions and any quota warning are also observed.

  • OpenAI Codex CLI · met the criterion (Codex CLI 0.154.0, on the ChatGPT Plus plan (paid), model gpt-6-astra, reasoning: high · October 8, 2026)
    It presented a three-point plan, asked for approval and stopped without writing code; after approval it created a single index.html and an AGENTS.md with 3 rules. Checking the page: with $20 and a rate of 49.1976 it shows 983.95 lira, 1,180.74 lira including VAT and 14,168.91 lira for 12 months; on empty and negative input it shows a warning and no result; it makes no requests to outside addresses and the whole interface is in Turkish. It reported that the 16 calculation checks it wrote itself passed. No quota warning appeared during the session.
  • Claude Code · met the criterion (Claude Code CLI, on the Claude Max plan (paid), model Opus 5.5 · October 8, 2026)
    It presented a detailed plan (inputs, calculation, number format, validation, 3 suggested rules) and asked for approval; after approval it wrote a single index.html and an AGENTS.md with 3 rules. Checking the page: with $20 and a rate of 49.1976 it shows 983.95 · 1,180.74 · 14,168.91 lira; a Turkish warning on empty and negative input; no outside requests. It stated plainly that it couldn't run the page in a browser itself in no-permission mode, and on its own warned that an input without a comma, such as '1.234', would be read as a decimal.
