It has only been about a week since Aside launched publicly, but the team behind the AI browser is already shipping a long list of improvements. After attracting plenty of attention with its debut, Aside has now rolled out new features, expanded AI model support, and addressed several performance issues that early users brought up.

One of the biggest additions is pinned tabs, which was apparently one of the most requested features after launch. You can now pin important tabs and jump between them using keyboard shortcuts.

The browser also supports more AI providers, including xAI’s SuperGrok, Kimi, Z.ai, and even custom providers. That means users can connect local LLMs through Ollama or LM Studio if they prefer running models on their own machines.

The update also focuses heavily on stability. Aside says it has fixed the signup issues that some users ran into, resolved known problems affecting Intel Macs, and reduced GPU rendering memory usage by roughly three times compared to the initial release.

I mentioned in my original coverage that the browser felt a bit slow during my first impressions. At the time, I assumed Hermes was probably the reason since I had it running in the background alongside several other apps. After using Aside over the past few days, though, it became pretty clear that the browser itself was contributing to the slowdown. My MacBook Air M2 would heat up noticeably, and the whole system became sluggish enough that I couldn’t realistically keep Aside open as part of my daily workflow. Interestingly, I wasn’t the only one who noticed it. Someone else also brought up the lag in Aside’s latest update thread, so it wasn’t just my setup.

Along with the larger changes, the update includes dozens of smaller fixes. The floating vertical tab sidebar now appears when you hover near the left edge of the browser. Firefox import support has been added, bookmark imports from Chromium browsers are more reliable, the bookmark bar now appears correctly on the New Tab page, and users can choose to display the full URL in the address bar again. The team also says it has improved the reliability of ChatGPT, Claude, and GitHub Copilot account connections.

Alongside the update, Aside co-founder Jun published a detailed post explaining how the company built its browser agent. The post claims that Aside currently leads several browser agent benchmarks, including Online-Mind2Web, Odyssey, and BU-Bench-V1. The company argues that much of its performance comes from building its own lightweight browser automation stack around Playwright instead of relying on more traditional browser control approaches.

Whether those benchmark results translate into a better real-world experience is something more users will judge over time. What’s clear already is that the team is moving quickly. Shipping this many fixes and features within days of launch suggests they’re paying close attention to early feedback, especially around performance, which was one of the biggest complaints after the browser first went viral.
