From idea to live app in 3 steps
No configuration, no DevOps, no waiting. Just describe what you want to build and ship it.
Step 01
Describe your idea
Type what you want to build in plain English — no boilerplate, no setup, no config.
- Use natural language: "Build me a SaaS dashboard with auth, a PostgreSQL-backed REST API, and a React frontend."
- Optionally upload a ZIP of existing code to continue building on top of your project.
- Choose your preferred AI model: GPT-4, Claude, Gemini, Grok, or DeepSeek.
Step 02
AI writes & runs your code
LinearPortal spins up an isolated container and the AI agent scaffolds, installs dependencies, writes components, and iterates until your app runs.
- A warm container is ready in under 5 seconds — no cold starts.
- The agent reads your existing files, installs npm/pip packages, runs build commands, and fixes errors automatically.
- Every AI edit is git-snapshotted so you can diff or roll back at any point.
Step 03
Preview, refine & ship
See your app running instantly in a live Vite HMR preview. Chat with the AI to refine or debug. Export, deploy, or keep building — everything persists.
- Share your live preview URL with teammates or clients — no deployment needed.
- Drop into the real terminal inside your container to run scripts or inspect logs.
- Download a ZIP to deploy anywhere, or connect a custom domain directly.
