The alternatives

OpenAI Codex: you've probably already got it

OpenAI's coding agent across app, CLI, IDE extension and cloud. Bundled into every ChatGPT plan: Go $8, Plus $20, Pro $100 a month, with limited use on Free. Already paying for ChatGPT? Crack on. Head-to-head: Claude Code vs OpenAI Codex.

Cursor: an editor, not an agent

If what you actually want is AI help while you type, Cursor's the default. Plus is $8/mo but Grok models only. Premium is $30 and lets you use Claude and others, billed separately at API list price. See Cursor vs Claude Code.

GitHub Copilot: cheapest serious option

Pro is $10/mo, Pro+ $39, Max $100. There's a free tier too. Good fit if your team already lives on GitHub.

Cline: open source, your rules

Free open-source extension for VS Code and a CLI. No subscription. Pay for inference at cost or bring your own API key. Want Claude models without a Claude subscription? Plug your Anthropic API key in here.

Google Antigravity: $0 to start

Google's agent-first IDE, desktop app and CLI. Individual tier is $0 with unlimited Tab and Command requests and basic weekly agent limits. Higher limits come via Google AI plans (prices per third-party checks, not confirmed on Google's page).

Kiro: specs before code

AWS's spec-driven agentic IDE. Free gets 50 credits a month, forever. Pro $20/mo for 1,000 credits. Good if you like planning before the AI starts swinging.

Grok Build: the new one

xAI's terminal coding agent with a TUI, headless mode and editor support via ACP. It's listed in Cursor plans: limited on Free, included from Plus ($8/mo). Very new, so we haven't scored it yet.
