100 Browser Agents You Can Build Today

Browser agents are quickly becoming one of the most exciting frontiers in software, and they’re starting to completely transform how we interact with the web. Instead of manually clicking through dashboards, copy-pasting data, or juggling dozens of tabs, we can now delegate these tasks to agents that run in the browser and work on our behalf.

This shift is part of a larger trend: the rise of browser agents. In 2025, AI is no longer just a chatbot — it’s a collaborator. Browser agents represent one of the most practical ways to harness that power right now. They are easy to build, easy to distribute, and can add value instantly without requiring users to install complex infrastructure.

Whether you’re a developer looking for your next side project, a startup founder searching for product ideas, or just curious about the future of computing, this list is for you. Here are 100 browser agent ideas you can build today — from the highly practical to the delightfully weird.

If you’re a developer, consider trying one of these as a side project. If you’re a startup founder, think about which of these could solve a painful problem for thousands of people. And if you’re just curious about the future of computing, keep an eye on this space — browser agents are just getting started :)
