This is super useful! I have immediate use for this.

Do you know if Servo is 100% Rust with no external system dependencies? (ie, can get away with rustls only?)

Can this do Javascript? (Edit: Rendering SPAs / Javascript-only UX would be useful.)

Edit 2: Can it do WebGL? Same rationale for ThreeJS-style apps and 3D renders. (This in particular is right up my use case's alley.)

It depends on stuff like SpiderMonkey so not pure Rust.

It should be able to render JavaScript but I've seen it throw bugs on simple pages, no doubt because my vibe-coded thing is crap not because Servo itself can't handle them.

I have been building/vibecoding a similar tool and unfortunately came to the conclusion that in practice, there are just too many features dependent on the full Chrome stack that it's just more pragmatic to use a real Chromium installation despite the file size. Performance/image generation speed is still fine, though.

In Rust, the chromiumoxide crate is a performant way to interface with it for screenshots: https://crates.io/crates/chromiumoxide

		> there are just too many features dependent on the full Chrome stack Do you mind elaborating on what features are missing?

		I think you could in theory have a similar webkit-based stripped down headless crate that might have a good tradeoff of features, performance, and size.

Servo does execute JS and does support webgl (and some but not all of webgl2 if you enable the feature: https://book.servo.org/design-documentation/experimental-fea...).
