Microsoft Agent Viewer
I missed clippy and bonzi buddy, so I spent the past few days reversing and implementing microsofts old agent format (acs) and wrote a small viewer on top of it (wasm + typescript) You can check out the code here as well: https://github.com/Ell/bonzi

In plain words
Microsoft Agent Viewer is a web-based tool that displays animated characters using Microsoft's legacy ACS (Agent Character) format from the 1990s. Built with WebAssembly and TypeScript, it allows users to view classic agents like Clippy and Bonzi Buddy in a modern browser. The creator reverse-engineered the old format and built this viewer to revive nostalgia for these iconic Microsoft assistants, with full source code available on GitHub.

Open-source browser for AI agentsMar 2026 · github.com · ▲155Hi HN, I forked chromium and built agent-browser-protocol (ABP) after noticing that most browser-agent failures aren’t really about the model misunderstanding the page. Instead, the problem is that the model is reasoning from a stale state. ABP is designed to keep the acting agent synchronized with the browser at every step. After each action (click, type, etc), it freezes JavaScript execution and rendering, then captures the resulting state. It also compiles the notable events that occurred during that action loop, such as navigation, file pickers, permission prompts, alerts, and downloads,…
Smooth CLI – Token-efficient browser for AI agentsFeb 2026 · docs.smooth.sh · ▲109Hi HN! Smooth CLI (https://www.smooth.sh) is a browser that agents like Claude Code can use to navigate the web reliably, quickly, and affordably. It lets agents specify tasks using natural language, hiding UI complexity, and allowing them to focus on higher-level intents to carry out complex web tasks. It can also use your IP address while running browsers in the cloud, which helps a lot with roadblocks like captchas (https://docs.smooth.sh/features/use-my-ip). Here’s a demo: https://www.youtube.com/watch?v=62jthcU705k Docs start at…
