About LastBrowser
The story, philosophy, and technology behind "the last browser you'll ever need."
Why Another Browser?
Modern browsers are incredibly powerful, but they're built for the general web — not for getting work done. Tab overload, constant notifications, and the friction between tools breaks focus. Productivity browsers like Wavebox and Sidekick solved this, but they're proprietary and expensive.
LastBrowser was born from a simple idea: what if your browser was also your workspace, your AI assistant, and your task manager — all open source?
Origin Story
LastBrowser started as "Hermes Desktop" — a lightweight Electron wrapper around the Hermes WebUI, an open-source AI agent interface. The wrapper added a system tray, sidebar, and native Windows integration.
As development progressed, it evolved into something much bigger: a full workspace browser with vertical tabs, isolated workspaces, AI agents, kanban boards, split view, focus mode, and a command palette. The project was renamed to LastBrowser in May 2026 with the v0.2.0 release.
Philosophy
- Open Source First: MIT licensed. No telemetry by default. No paid tiers. Your data stays on your machine.
- AI-Native: AI agents aren't an add-on — they're built into the browser's DNA. Agents can browse tabs, automate tasks, and work alongside you.
- Productivity Over Polish: Features first, aesthetics second. Dark theme, keyboard-first navigation, minimal chrome.
- Self-Hosted: You control your data, your agents, your workspace. No cloud dependency.
Technology
LastBrowser is built on three layers:
| Electron v35 | Native shell — window management, system tray, auto-update |
| Node.js + IPC | Main process with 21 modules, ~150 IPC channels, SQLite storage |
| Hermes WebUI | Python AI agent backend — multi-provider, streaming, memory, skills |
Who Made This?
LastBrowser is built by Pup Cid (also known as Cid), an independent developer focused on AI tooling and productivity software. The project is developed openly on GitHub — contributions, issues, and feature requests are always welcome.
