Moli Browser

Moli is a production-ready headless browser for AI agents. Its on-demand layout and rendering design combines a complete browser runtime with a lightweight resource footprint.

Moli helps your AI agent fetch and extract web pages, search the web, and automate browser tasks.

Use it through the CLI, CDP, WebDriver Classic, or WebDriver BiDi.

Why MOLI ?

•Full-featured — real JavaScript, DOM, CSS, networking, storage, layout, screenshots, and standard automation protocols, all integrated into one headless browser.

•Fast — most automation requests never need visual rendering, so structure-first operations skip layout and paint entirely.

•Resource-efficient — layout and pixels are generated only when needed, so Moli does not have to continuously maintain and update a fully rendered visual state.

Current capabilities

•Complete web runtime — streaming HTML parsing, native DOM, V8 JavaScript, modules/timers/microtasks/events, iframes and workers, CSS cascade, Fetch/XHR/WebSocket, cookies, WebCrypto, and profile-scoped storage (localStorage, IndexedDB, OPFS).

•Extraction-optimized outputs — the CLI directly produces HTML, Markdown, JSON, semantic text trees, and frame-aware serialization, with selector/script/response waits and network tracing.

•Unified automation binary — CDP, WebDriver Classic, and WebDriver BiDi share the same kernel and scheduler. No separate ChromeDriver, geckodriver, or browser installation is required.

•Real visual capabilities on demand — add --layout to enable complete box construction, Taffy layout, Parley text layout, layout-backed hit-testing/input, viewport screenshots, and low-frequency CPU-rendered DevTools screencast frames.

•Controllable operational options — profiles, cookies, HTTP cache, proxies, resource families, connection limits, timeouts, private-network policy, user-agent overrides, diagnostic logging, and network diagnostics are all available.
