New web platform features include the :checked pseudoclass, the user-select property, the element, CSS typed arithmetic, and the alpha() CSS function. The devtools console now eagerly evaluates JS inputs for faster feedback. SpiderMonkey was upgraded to v153.3 and mozangle to v0.7, fixing upstream security bugs. WebGL2 conformance improved, and WebGL is now part of default_web_features, so embedders who don't want it must disable default features. Multiprocess mode is enabled at build time with the new Cargo feature multprocess, and removing it cuts binary size by about 2MB. The project now receives 8144 USD per month in recurring donations. ## Full article daily.dev links to this article rather than hosting it.

Servo 0.7.0 bundles 527 commits from September, adding the :checked pseudoclass, the user-select property, the element, CSS typed arithmetic, and the alpha() CSS function. It also upgrades SpiderMonkey to v153.3 and mozangle to v0.7 for security fixes, and brings major WebGL2 conformance improvements. _Developers tracking Servo's engine progress can follow release notes like this on daily.dev._ ### How do I disable WebGL support when embedding the Servo browser engine? Disable default features when building Servo, since the webgl feature was added to default_web_features in version 0.7.0. Previously WebGL support was opt-in; now embedders who don't want to ship with WebGL must explicitly turn off default features at build time. _Developers embedding browser engines like Servo can keep up with build-flag changes via daily.dev._ ### How much does removing multiprocess mode save in Servo's binary size? Removing the multiprocess feature reduces Servo's binary size by about 2MB. Multiprocess mode is now enabled at build time through the new Cargo feature called 'multprocess', so builds with default features disabled drop that support and the associated size. _Engineers optimizing embedded browser binary size can track engine-level changes like this on daily.dev._ ## Community take How the wider developer community reacted, aggregated from 2 discussions and 47 comments across lobsters, hackernews (as of 2026-11-05). **TL;DR:** Discussion centers heavily on Servo's ban on AI-generated contributions, with people split between defending it as prudent and warning it will slow the project's already volunteer-limited pace, alongside general enthusiasm for Servo's progress as an embeddable engine and comparisons to Ladybird. **Sentiment:** 35% positive · 45% mixed · 20% skeptical **The case for** - Pre-built releases (including Android APKs) make Servo practical to actually use day-to-day. - Several people report good experiences embedding Servo as a library to build their own browsers or apps. - The AI contribution ban is seen by some as a reasonable, clearly-justified policy to protect project health. - People find it heartening that a largely volunteer effort is making steady progress. **The pushback** - The strict ban on AI-generated code is seen by others as a competitive disadvantage that will make Servo fall behind projects embracing AI assistance. - Some suspect the policy is unenforceable in practice and that AI-assisted contributions slip through anyway. - Commit volume (527 vs Chromium's 20,000+) highlights how much slower progress is compared to major browser engines. - Basic features like and :checked were missing until this release, surprising some given how established the project is. - UI polish and usability features like keyboard shortcuts for daily-driver use are still lacking. **By community** - lobsters (mixed): Conversation stays technical and speculative, discussing Servo as a second independent engine implementation and wishlist items like a more parallel JS engine or better vectorization. - hackernews (heated): Dominated by sharp disagreement over Servo's AI contribution ban, split between support for the cautious policy and frustration that it will hamper progress, alongside praise for Servo's embeddability and comparisons to Ladybird. **Hottest debate:** Whether Servo's policy banning AI-generated code contributions is a prudent safeguard or a self-inflicted handicap that will leave it behind projects embracing AI-assisted development like Ladybird. **Open questions** - Will Servo revise its AI usage policy as tools and practices mature? - How much faster could Servo's feature gaps (e.g. CSS spec coverage) close with careful AI assistance versus pure human effort? - How will Servo's progress compare to Ladybird's over the next year given their diverging approaches to AI tooling? **Highlights** > Part of this, as others have noted, is due to: https://book.servo.org/policy/ai-usage.html > Can I submit a PR that includes code generated by AI tools? > No. This includes (but is not limited to) all generative AI tools like Claude, Codex, ChatGPT, Cursor, Gemini, and Windsurf. For something like a browser, this de facto limits the set of people who can contribute to something that touches the layout engine (e.g. the ineffable but brilliant https://github.com/servo/servo/blob/main/components/layout/f...) to just those already familiar with the code. A much better middle ground IMO would be to quarantine first-time committers behind an AI-generated-PRs-will-not-be-reviewed policy, but to allow those who understand and respect the cycle enough to get PRs accepted, to begin using AI to give the team leverage. Without some kind of policy like that, Servo's sadly going to fall behind literally any other open-source project that people could dedicate their time towards. > — [btown on hackernews](https://news.ycombinator.com/item?id=50385066) > Servo is really great: Rust seems like a no brainer choice for a modern web engine, and its clean, performance-focused design from the ground up is wonderful. But it seems really hard for it to get anywhere just based on occasional contributions from volunteers. I was actually quite surprised that basic functionality like and the :checked attribute were not even supported prior to this release. Servo got 527 commits, while Chromium has over 20,000 commits. > — [porphyra on hackernews · 1 comments](https://news.ycombinator.com/item?id=50384805) > (I'm the maintainer of Blitz) My experience is that it varies greatly by feature. Something like border styles, the agent was able to do pretty effectively. Although it still took a few hours iterating on it to get the performance characteristics and edge cases right. More complex features like hoisting position absolute nodes and other layout features still take days to weeks of iterating to get something usable that isn't so fragile it'll blow up the next time you touch something. > — [nicoburns on hackernews](https://news.ycombinator.com/item?id=50382159) > The progress on Servo is impressive. UI polish is required in order to be more usable. Things like keyboard shortcuts to focus the address bar are required to make it feasible for more daily driving use > — [moderation on hackernews · 3 comments](https://news.ycombinator.com/item?id=50380987) > While Ladybird produces the flashier demos at the current point in time I hope Servo can continue its development to act as a second independent implementation of web rendering now that Ladybird has gone hard into AI-powered development. I understand that almost everything about the projects are different: scope, funding, programming language (although not entirely anymore since Ladybirds transition to Rust), etc. But I think it could serve as an interesting case study in the AI and non-AI development methods in the future, despite all these differences. > — [vincent-uden on lobsters · 2 points, 1 comments](https://lobste.rs/s/u26wki/september_servo_progress_rounded#c_gmzqsq) **Source threads** - [lobsters](https://lobste.rs/s/u26wki/september_servo_progress_rounded) · 46 points · 7 comments - [hackernews](https://news.ycombinator.com/item?id=50379576) · 155 points · 40 comments ## Similar posts on daily.dev - [June in Servo: real world compat, media queries, SharedWorker, and more](https://daily.dev/posts/june-in-servo-real-world-compat-media-queries-sharedworker-and-more-wihizhsml) · Hacker News · 0 upvotes · 0 comments - [April in Servo: new Android UI, focus, forms, security fixes, and more\!](https://daily.dev/posts/april-in-servo-new-android-ui-focus-forms-security-fixes-and-more--j1hqc21nn) · Lobsters · 0 upvotes · 0 comments - [Servo 0.3 Released With The Demo Browser Becoming More Useful](https://daily.dev/posts/servo-0-3-released-with-the-demo-browser-becoming-more-useful-praenbgmk) · Phoronix · 2 upvotes · 0 comments --- Tags: [#css](https://daily.dev/tags/css), [#rust](https://daily.dev/tags/rust), [#browsers](https://daily.dev/tags/browsers), [#webgl](https://daily.dev/tags/webgl) [View this post on daily.dev](https://daily.dev/posts/servo-aims-to-empower-developers-with-a-lightweight-high-performance-alternative-for-embedding-web--gquzifnxv) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Servo aims to empower developers with a lightweight, high-performance alternative for embedding web technologies in applications.","url":"https://daily.dev/posts/servo-aims-to-empower-developers-with-a-lightweight-high-performance-alternative-for-embedding-web--gquzifnxv","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/servo-aims-to-empower-developers-with-a-lightweight-high-performance-alternative-for-embedding-web--gquzifnxv"},"datePublished":"2026-11-05T13:41:53.838Z","dateModified":"2026-11-05T22:08:59.018Z","description":"Servo 0.7.0 ships all changes landed in September, spanning 527 commits.
