wtf is opencode-lightpanda?

opencode-lightpanda is a plugin for OpenCode, an AI coding assistant, that adds a faster and more capable way to fetch web pages. The author describes it as similar to the built-in WebFetch tool, but much stronger, calling it that tool on steroids. The plugin is built on top of Lightpanda, a lightweight headless browser. According to the README, Lightpanda runs about ten times faster than headless Chrome and uses about sixteen times less memory. Because it is a real browser rather than a simple page fetcher, it can load pages that rely heavily on JavaScript to build their content, something a basic fetch request often cannot handle. Once a page loads, the plugin returns clean markdown text with ads and clutter stripped out, so the assistant reading it gets readable content instead of raw, messy HTML. It can also return the page as structured JSON data or as a semantic tree, depending on what the calling tool needs. To use it, you first install Lightpanda itself, then install this plugin globally through OpenCode's plugin command. If OpenCode cannot find the Lightpanda executable automatically, you can point to it directly using an environment variable. Each time the tool is called it starts a fresh Lightpanda process, so no cookies or browser history carry over between calls, keeping every fetch independent and predictable. The project is written in TypeScript and uses Bun for local development, testing, and running checks. Developers who want to work on the plugin itself can also load their local checkout directly into OpenCode's configuration file instead of installing the published version. OpenCode also lets users control this tool and the standard WebFetch tool separately through permission settings, so one can be allowed while the other is denied. This is a narrow, practical developer tool aimed at people already using OpenCode who want faster, cleaner web page access for their AI coding workflows.
