Lightpanda
LightpandaHeadless browser written in Zig for agent and automation workloads, implementing the DOM and a JavaScript runtime through V8 without rendering pixels, so pages are executed rather than drawn. Speaks the Chrome DevTools Protocol, so Playwright and Puppeteer clients drive it in place of Chrome.
Openness
5 high confidence- license
- AGPL-3.0(OSI, copyleft)
- source
- public(the repository builds the browser binary)
- core features withheld
- no — the hosted Lightpanda cloud is a separate managed service, not a carve-out of the published engine
LICENSING.md, the LICENSE file and the GitHub metadata all agree that the project ships under AGPL-3.0, an OSI-approved license, and nothing is appended after the license text. The repository builds the browser binary itself, and the hosted Lightpanda service is a separate, managed offering sold beside the engine rather than a feature held back from it, so nothing in the core is withheld.

README, read for the distribution and gating question: it documents building the browser from this repository ("Lightpanda is written with" Zig) and starting a CDP server for Puppeteer or Playwright clients, with no enterprise directory, license key, pricing or withheld component described.
Adoption
3 low confidenceLightpanda ships as a binary rather than a package on PyPI or npm, so no download count exists and GitHub stars are the only available adoption signal. That reading should be treated as a floor rather than a precise measurement, since a star count shows attention rather than use.

Capability
not assessedLightpanda has no separate system behind it: it is the browser itself, implementing the DOM, a JavaScript runtime and the Chrome DevTools Protocol that tools such as Playwright MCP and Browser Use adapt. Because it is the system rather than a layer over one, the map assigns no capability score here.
- https://raw.githubusercontent.com/lightpanda-io/browser/main/README.md recorded 2026-08-30
README documents a headless browser written in Zig implementing the DOM and a JavaScript runtime through V8 with no rendering, exposing the Chrome DevTools Protocol for Playwright and Puppeteer clients, and notes that Web API coverage is partial and in progress.
