Dendrite was a Python SDK built by Dendrite Systems (founded 2023 by Arian Hanifi, Charles Maddock, and Sebastian Thunman) designed to give AI agents the ability to operate inside a web browser. The SDK let developers write agents that could log into websites, navigate pages, fill forms, extract structured data, and handle file uploads and downloads, all using natural-language instructions layered over Playwright-based browser automation. The core value proposition was simplifying authenticated web automation: rather than writing brittle CSS selectors or XPath queries, developers described the action they wanted and Dendrite translated that into browser interactions. The SDK also included intelligent caching to speed up repeat runs and reduce LLM inference costs, plus a self-healing mechanism that attempted to adapt scripts when page layouts changed. Dendrite supported scaling via Browserbase-hosted browsers, allowing agents to run in parallel cloud browsers rather than on local machines. The SDK was distributed on PyPI, required Python 3.9+, and used Playwright under the hood. A separate examples repository on GitHub demonstrated common use cases such as retrieving bank transactions, scraping product listings, and automating SaaS workflows. As of early 2026, the Dendrite SDK is no longer under active development. The founders announced the project would remain fully open source so the community can study, fork, or adapt the code, but no new features or bug fixes are being shipped. Users looking for an actively maintained alternative are directed to projects such as Browser Use. The dendrite-systems.com domain and GitHub organization remain accessible. Key features: - Authenticated web browsing: agents can log into websites and maintain sessions - Natural-language browser interaction built on Playwright - Structured data extraction from any website - File upload and download support - Intelligent caching to reduce repeat LLM inference costs - Self-healing scripts that adapt when page layouts change - Browserbase integration for scaling to cloud-hosted parallel browsers - Fully open-source (MIT-style) with PyPI distribution
Free and open source. The SDK is available on PyPI at no cost. No commercial tiers are currently offered as active development has ceased.
