I built Raq.com – a platform that uses Claude Code to build working internal tools directly in the browser.
Claude Code is great at self correcting when given the right tools.
I've found that the popular web-based AI coding tools look great in demos but fail on real API integrations or require a lot of error back and forth. They don't appear to do much research or self-correcting, likely to reduce spend. I wanted to see the current state of these tools, so I ran the same prompt on five platforms (Replit, Bolt, v0, Lovable, and Raq.com) to build a tool that requires 3 different APIs (Companies House, FinUK and OpenRouter) working together.
Four platforms produced broken prototypes or needed manual fixes. Raq.com delivered a complete working solution from a single prompt (that can be deployed to live with one click).

We're in early access (requires Claude Pro/Max for free usage) - we're looking non-coders who would like to build internal tools for their team.
Some technical info:
- Raq.com provisions isolated dev and prod Docker environments for each company (companyname.raq.com and companyname-dev.raq.com).
- The dev site includes a persistent terminal streamed to the browser, so the session continues even while tab is closed.
- CLAUDE.md file provides best practices, known pitfalls, and coding patterns for the Laravel + Filament stack.
- Self-Correction Loop: Claude can test and debug its own work. It has direct shell access to a custom script that bundles PHPUnit, syntax checks, and cache clearing. Plus a Playwright wrapper to check for errors and take screenshots.
- A single click runs a script that rsync's the dev workspace to the prod container, runs migrations, and clears caches.
