Rill Browser: The browser where Claude Code and Codex work beside you
Rill is in free beta for macOS 14 or later on Apple silicon. It is built on WebKit, so it runs natively on the Mac. Users sign in to Claude Code, Codex or both. Rill pulls projects from the agents' own history, so there is nothing to configure. Agents can also take on web errands such as a flight search, which runs in a tab behind the one the user is reading. A "Stay Signed-In" feature carries over logins from Chrome. In one daily roundup, Rill ranked first among Product Hunt AI launches over 24 hours, with 403 votes. The space is crowded. Within two days of each other, Codex and Claude Code both shipped upgrades to their in-app browsers. BrowserOS neo, formerly BrowserClaw, is an open-source browser that agents drive using the user's logged-in accounts. The makers argue that Chrome extensions are limited to improving what is already in the browser. For founders, the lesson is in the pricing. Rill charges nothing for compute and runs on the Claude Code or Codex plans users already pay for. A thin client like this can launch cheaply, but it depends on Anthropic and OpenAI keeping their own browsers behind it.
