Code & Builder

Ship a SaaS by Sunday. Design, scaffold, build, deploy without leaving the AI loop.

Ship a SaaS by Sunday with Gemini's 2M-token context window holding the whole codebase as one file.

Plan with Claude, hand off to Claude Code in the terminal for autonomous edits, let CodeRabbit review, fix what it finds, ship.

One surface, end to end. Claude Code does the planning AND the implementation; CodeRabbit reviews.

OpenAI's Codex on two surfaces: CLI in the terminal for hands-on work, Cloud for fire-and-forget PRs.

Cursor as the primary surface. Inline edits, agent mode for multi-file work, CodeRabbit on the PR.

Ship an iOS app from scratch: Cursor for Swift code, Xcode for build/sign/TestFlight, Claude for product decisions.

Ship a Kotlin app: Cursor and Claude for the code, Android Studio for build, signing, and Play Console upload.

One codebase, both app stores. Expo + React Native, Cursor for the code, Claude for the architecture, EAS Build for native compile.

Run thousands of LLM calls a day for the price of a coffee. DeepSeek for production volume, Claude as the calibration and eval surface.

Run frontier-grade LLMs on weights you can inspect, self-host, and audit. Llama for general work, Mistral when EU data residency matters, Claude as the calibration eval.

Prompt a working full-stack app: Lovable scaffolds the UI, wires Supabase, drops in Stripe, and deploys to a live URL.

v0 generates the React + shadcn UI; Cursor wires the backend + DB; Vercel deploys.

No local install, no terminal. Replit Agent builds, runs, and hosts the app in your browser.

Google's IDE on top of Gemini's 2M-context. Especially clean if your stack is GCP, Firebase, Android, or Workspace.

Windsurf's Cascade agent plans + executes multi-step changes in the IDE. Fewer per-turn cycles on big diffs than Composer.
