v0.2.0

Obscura can now render and capture modern web pages directly, without bundling or launching Chromium. This release adds a native Rust rendering engine, screenshots, scrolling, screencasting, and PDF export through the CLI, MCP, Puppeteer, and Playwright. 449 commits since v0.1.11.

Highlights

• Native rendering: block and inline layout, Flexbox, Grid, tables, floats, positioning, scrolling, transforms, text shaping, images, SVG, Canvas, forms, gradients, shadows, and animations.
• Modern websites: external stylesheets, JavaScript modules, dynamic imports, hydration, responsive images, web fonts, observers, Shadow DOM, and custom elements.
• Screenshots: viewport, clipped, scrolled, and full-page capture with PNG, JPEG, and WebP output through CDP.
• Screencasting: activity-driven PNG or JPEG frames with sizing, quality controls, acknowledgement backpressure, and isolated CDP sessions.
• PDF export: print styles, pagination, paper sizes, margins, scale, landscape mode, backgrounds, page ranges, and streamed output.

CLI and automation

Capture a page directly:

obscura fetch https://example.com --screenshot page.png

Puppeteer and Playwright can use their normal screenshot and PDF APIs through Obscura's CDP endpoint. Pages can be scrolled through JavaScript, mouse-wheel input, or DOM.scrollIntoViewIfNeeded.

Render-enabled MCP builds add browser_screenshot and browser_pdf.

Browser compatibility

This release also improves:

• React-controlled form filling through MCP
• Namespaced and qualified attributes
• cloneNode() and context-sensitive HTML fragments
• Event, CustomEvent, PromiseRejectionEvent, and StorageEvent behavior
• String timer execution
• Dynamic data: scripts
• Style attribute synchronization
• Quirks-mode selectors
• Platform CA certificate support
• Compressed responses through the stealth transport
• HTML charset detection

Release downloads

Every supported platform now receives four builds:

The default archive and Docker image include rendering. No-render builds preserve the existing lightweight automation configuration.

Current limitations

Rendering is new and is not yet complete Chromium parity. Long-tail CSS, some Web APIs, native media playback, and GPU compositor effects may still differ.

PDF output is currently raster-backed, so text is not selectable. Screencasting captures page activity rather than fixed-rate desktop video.
