Tidewave Web positions itself as an in-browser coding agent specifically for Rails and Phoenix development, which is a smart niche play in the crowded AI coding space. The browser-based approach is appealing since it eliminates setup friction, and focusing on specific frameworks allows for more tailored assistance than generic coding tools.
However, this is still primarily a developer tool rather than something non-technical business owners would use directly. While the agent capabilities sound promising for automating coding tasks, the target audience is clearly developers working with Rails or Phoenix applications. The HackerNews traction suggests there's genuine interest from the developer community, but we'd need to see more details about pricing, capabilities, and real-world performance to fully assess its value proposition.
