CSS Pro is a universal visual CSS editor that allows users to rapidly experiment with design ideas directly in their browser. It generates CSS code without needing to import libraries or change existing code. This tool offers live editing of design properties, enabling users to see changes in real-time and receive clean, usable CSS output. The service includes a Before/After toggle for easy comparison of edits, and users can share their modifications via links, making it convenient for teams and clients to review updates. The platform provides AI assistance through advanced models like Claude Opus 4.5 and ChatGPT 5.2, which help automate the coding process. Users can copy prompts for AI tools to apply their CSS changes directly to their codebase. CSS Pro has gained positive feedback for transforming workflows, especially in agency settings, where quick prototyping and real-time client demonstrations are essential. Users appreciate the significant time savings and ease of use compared to traditional development tools. CSS Pro comes in three pricing tiers: Pro at $10/month for individual use, Pro MAX at $15/month for up to three activations with additional features like AI requests and priority support, and a one-time Lifetime Pro MAX option for $900. The extension works with major browsers like Chrome, Firefox, and Safari, but requires macOS 10.13 or later for Safari users.
