The Laboratory

What happened to Arc, the “Chrome replacement”?

There is a rhythm to the madness of how the internet functions and how it changes based on user patterns. Despite being full of different webpages, platforms, and forums, the online space continues to evolve, and with it, the way we interact with it.

So far, we have looked at the internet as a space accessed via a computer system that functions with its own operating systems (OS). But with changes in how data is shifting to the cloud, the logical evolution for the internet would be to have its own OS, or at least that is what The Browser Company thought it should be.

The company worked with the thought process of launching a browser called Arc, which tech enthusiasts dubbed the “Chrome replacement” they had been waiting for. However, despite the success of its first browser, the company has now decided to stop development of Arc to focus on a more ambitious project: launching a more AI-centric project to simplify everyday tasks using AI tools.

Let us look at how and why The Browser Company chose to develop Arc, let go of its success, decided to transition to AI, and what all this turmoil could mean for users.

Rethinking browsers in the age of cloud

The Browser Company was co-founded in 2019 by Josh Miller (former Director of Product at both White House and Facebook) and Hursh Agrawal (formerly at LinkedIn and Code & Theory). Their mission: to reimagine the web browser as a productivity tool rather than just a document viewer.

The idea for Arc was born out of the shift in user habits and the industry as a whole. More and more breakout startups were browser-based, with even financial assets like crypto running through browser extensions, resulting in a change in the amount of time users spent on browsers rather than interacting with the native OS of their device. This idea drove the company to build a browser that could transform existing browsers from what they used to be—a highway for information—into a more native space on a device, where users could access everything they needed in a more streamlined way.

How the Arc browser challenged Chrome

One of the standout features of the Arc browser is the innovative sidebar, which replaces the conventional horizontal tab layout. This sidebar serves as a central hub, integrating tabs, bookmarks, and even media controls, thereby streamlining the user experience. This, according to reviewers, allowed users to interact with web content in a more organized and efficient manner.

Arc also introduced the concept of "spaces," allowing users to create distinct workspaces for different tasks or projects.

And while the browser was never touted or claimed to be perfect, it received resounding praise from reviewers and users alike.

By 2024, The Browser Company had raised $50 million in a round led by Pace Capital at a $550 million valuation. However, things were about to change, and the company was set to pivot toward a new direction.

The rise of Dia

In December 2024, The Browser Company announced it would launch a more AI-centric product called Dia. The company claimed the new web browser would be built to simplify everyday internet tasks using AI tools and would launch in early 2025.

The new browser would come with enhanced AI capabilities, which would allow it to suggest lines with facts from the internet, generate ideas for users, and summarize tabs.

According to a message on the company’s website, “AI won’t exist as an app. or a button,” it would be an entirely new environment built on top of a web browser.

Why did Arc stumble despite early praise?

Arc earned a loyal fanbase but struggled with mainstream adoption due to what Miller calls the “novelty tax.” It was too different and complex for most users, offering too little immediate payoff. While hardcore users loved the features, data showed very few people actually used them regularly.

Despite solid retention among early adopters, Arc’s usage resembled that of a niche professional tool, not a mass-market product.

Additionally, Arc and even Arc Search were ultimately too incremental and lacked the transformative scale the company aspired to. The rise of AI tools like ChatGPT, Perplexity, and Cursor, which disrupted long-stagnant industries, signaled a moment of true behavioral change that the team saw as a rare opportunity to rethink the browser from the ground up.

All these factors paved the way for the company to ditch Arc in favor of a new project, which would focus on features like tab chat and personalization, offering clearer value and accessibility.

Arc’s future: Security updates, no new features

The Browser Company has confirmed it is not discontinuing Arc but will no longer develop new features for it.

In a blog post, CEO Josh Miller explained that Arc, while innovative, is too complex and unstable to go mainstream.

Miller cites security as a key reason for not merging Dia into Arc. Arc previously had a serious vulnerability that allowed remote code execution with just a user ID. Since then, the security team has expanded from one to five people, especially as AI agents become more prominent.

While Arc will continue to receive security and bug fixes, it won’t be open-sourced or sold, as it shares core infrastructure with Dia. The company says it might open Arc in the future, but only when it no longer poses a risk to the team or shareholders.

What does the Arc’s journey mean for users?

The Arc browser was seen as a fresh face in the web browser space, a space that had not seen any major changes in decades. The Arc browser embarked on a journey to change that and was capable enough, despite its flaws, to be seen as an alternative to serious contenders like Chrome.

Despite the challenges, the Arc browser was able to convince users of a simple truth: they spend more time on their browser than with the actual software loaded on their device, and browsers needed an overhaul to be more streamlined according to how they are used.

While the Arc browser may not have gone mainstream or led to a tidal shift in consumer preferences, it has shown that the browser space needs more innovation. With Dia now being the focal point and AI reimagining human-machine interactions, the time is ripe for tech companies to rethink their browser strategy.
