What it is

Screenshot of the LastBrowser homepage — lastbrowser.com, as visitors see it

LastBrowser is the first AI-native web browser built for Windows and Linux (Linux in preview), combining modern development tools with comprehensive privacy protection. It features Sidekick, an integrated AI assistant supporting bring-your-own-key (BYOK) models and local Ollama integration, alongside 48 curated agentic workflows for tasks like document summarization and regex debugging.

The browser includes a native Windows ConPTY PowerShell terminal accessible via Ctrl+`, allowing developers to run PowerShell, CMD, Git, npm, Python, and local models without switching windows. Multi-Account Spaces provide complete session isolation with separate cookie jars and caches, enabling seamless switching between work and personal accounts in the same window.

Castlabs Widevine DRM L3 integration ensures full HD streaming compatibility with Spotify, Netflix, Disney+, and Prime Video. All browsing history, tabs, passwords, and API keys remain encrypted locally on the user's computer via Windows DPAPI, with zero involuntary telemetry and 100% GDPR compliance. The browser is free for Windows 10 and 11 (64-bit), requires no account registration, and operates entirely local-first.
