lightpanda-headless-browser
Use Lightpanda (a Rust/Zig-based headless browser) when you need a fast, low-footprint render of a page — e.g. CI smoke for OctoCode's WebUI on small runners, or probing that / returns a live DOM instead of a 500.
When to use
- Quick liveness check of the WebUI before running a heavier Playwright suite.
- Headless rendering on resource-constrained environments (ARM, small VMs).
- Lightweight scraping of the page's rendered DOM when full Chromium is overkill.
Requirements
lightpanda binary on PATH, or resolved via the OctoCode tools-hub registry.
Minimal invocation
lightpanda http://127.0.0.1:10038 --timeout 5000 --dump-dom > tmp-lightpanda-dom.html
Integration notes
- Pairs well with
playwright-webui-qa: use Lightpanda for the "is it alive?" gate, then Playwright for semantic assertions.
- Intentionally does not replace Playwright for interaction-heavy flows (no full CDP coverage yet).
