NEXUS AI

AI coding tools can generate an impressive first pass. The harder part starts after that: verifying the code, connecting data and storage, sharing a working preview, and moving the same project into production without stitching together another toolchain.

We built NEXUS AI to make that one workflow.

Describe the app you want, and the Builder edits real project files. It runs project checks in an isolated development sandbox, inspects failures, and revises the code. You can iterate in an instant browser preview or a real full-stack Next.js sandbox, attach a design mockup, or click an element and ask for a targeted change.

When the app is ready, publish a frozen share link, let someone remix it, push it to GitHub, or deploy it with managed Postgres, S3-compatible storage, Stripe secrets, backups, workers, and a public HTTPS URL.

NEXUS AI can also operate deployments through the dashboard, CLI, API, or 61 MCP tools for Claude, Cursor, Codex, and other MCP-compatible agents.

The free plan includes one active deployment and requires no credit card.

I'd especially value feedback on one question: where should an app-building agent act autonomously, and where should it always stop for confirmation?
