An Al-powered vertical tabs manager in your side panel.
An alternative to Arc’s Sidebar and Edge’s Vertical Tabs — now upgraded with a built-in AI assistant.
Side Space gives you complete control over your browsing experience with powerful vertical tab management and Side Copilot, an AI that helps you research, organize, and automate your workflow directly from the side panel.
🚀 How do vertical tabs work?
When vertical tabs are enabled, your open tabs are moved from the top of the browser window to the left side panel. This layout stacks tabs vertically instead of horizontally, giving you more space, better visibility, and easier navigation—especially when working with many tabs.
✨ Features
💾 Space Backup Solutions
✨ AI-powered Tab Grouping for automatically organizing related tabs.
🔗 Group Guardian automatically groups tabs based on URL patterns.
🤖 Introducing Side Copilot — Your AI Assistant in the Side Panel
Side Copilot brings AI directly into your browsing workflow:
Just open AI Chat in the extension and start talking to your browser — it does the rest.
Side Space DEV.toSide Space's answer
Side Space combines powerful vertical tab management with an integrated AI assistant, that's something no other browser extension offers.
Instead of choosing between a better tab manager or an AI browser, Side Space gives you both in one clean side panel.
Side Space's answer
I am the kind of person who always ends up with too many tabs, too many windows, and no idea where that one page I read yesterday has gone. I tried a bunch of the new AI browsers, but they all felt like replacements for tools I already rely on. I didn’t want a new browser. I just wanted my existing one to feel less chaotic.
So I built Side Copilot for myself first. It helps me manage tabs, jump between windows, find stuff I opened days ago, and generally clean up the mess I constantly create. The thing that changed everything for me was giving it the ability to understand natural commands. I can tell it to group my research tabs or bring back an article from last week and it actually does it. It also has a simple chat mode for quick summaries or translating a page on the spot.
I realized it solved a real problem for me, so I decided to make Side Copilot completely free. I’m curious how other heavy browser users feel about this. Would an assistant like this make your browsing less stressful?
Side Space's answer
Most AI tools only analyze text. Side Copilot controls your tabs, windows, history, and pages using real browser APIs. You can research, summarize, organize, open sites, perform searches, restore sessions, and automate actions — all with natural language.
You don’t need to switch to Arc or Edge. Side Space turns Chrome’s side panel into a clean vertical tabs system with:
Drag-and-drop tab & group management
Fuzzy search
Memory-saving tab suspension
Saved spaces & session restore
Cloud sync
Dark mode
You get a modern browser experience without leaving Chrome.
Chat Mode → instant content analysis (summary, translation, extraction, quick answers)
Agent Mode → deep automation (organize tabs, clean up windows, run research workflows)
Fast when you need speed, powerful when you need automation.
Side Copilot isn’t “just another chatbot.” It uses more than 20 AI MCP tools built on Chrome Extension APIs:
Tab tools: create, close, group, move
Window tools: tile, arrange, focus
History tools: analyze, find, reopen past pages
Page interaction tools: scroll, navigate, search, capture screenshots
Session tools: restore recently closed tabs/windows
This gives Side Space automation capabilities even AI browsers don’t have.
Side Space's answer
Side Space is designed for anyone who works, researches, or creates directly in the browser — especially those who manage dozens of tabs every day. If the browser is your workspace, this is for you.
Productivity-Driven Professionals
Marketers, PMs, developers, designers, analysts — anyone who needs a smarter, faster way to organize tabs, windows, and workflows.
Power Browsers with Endless Tabs
For users juggling 20–200+ tabs across multiple windows. Side Space brings structure, clarity, and smart automation without forcing you to switch browsers.
AI-Forward Users
If you want to control your browser with natural language, automate tasks, and let Side Copilot handle the heavy lifting, this is your perfect tool.
Researchers & Knowledge Workers
Students, academics, journalists, content creators, and anyone who collects and analyzes information online. Summarize, extract, search, and research pages instantly.
People Who Want Arc/Edge-Style Features — But in Chrome
Enjoy a vertical tabs manager, powerful side panel, and full AI assistant experience without giving up the browser you already love.
As a mini-blog, it is a nice alternative for Medium to publish and share information about programming.
However, the community and the organization are biased toward social justice (and they are open to it). You can read its Code of Conduct, it is so vague and politically leads (I prefer a term of service because it defines fair rules for everybody). So it alienates developers that we don't care about politics in pro of people that want to talk about any other topic such as sexuality, how women are unprivileged, and such. It even mandates to use inclusive language. Good grief.
My main complaint is the quality of the community. It is not StackOverflow (so we don't want to ask for an answer here), and most of the top topics are clickbait, such as "how to become a rockstar developer in ... days", "100 tips to become a better programmer" (and it doesn't even talk about programming).
Technically this "mini blog" site allows us to use markdown, and it is okay. However, the whole experience is really basic. Even the template is ugly.
Based on our record, DEV.to seems to be more popular. It has been mentiond 675 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
That is also why places like dev.to matter. I feel that an open publishing commons for developers only stays meaningful in the long run if we can also choose how our software reaches users. My recipe right now: Play when it fits, F-Droid, IzzyOnDroid, and Obtainium when features and honesty demand it, and direct distribution when we must. Agentic tooling only raises the stakes: when software can request contacts,... - Source: dev.to / about 17 hours ago
On DEV (powered by the open-source Forem codebase), we have a hybrid architecture that blends Rails server rendering, Fastly edge caching, and lightweight client-side navigation (via InstantClick). This setup delivers sub-100ms page transitions, but partial page swaps combined with aggressive edge caching create delicate deployment challenges. - Source: dev.to / 5 days ago

Per-syscall interception is the layer that closes this gap. Grith sits between the agent process and the kernel, scoring every operation before it executes - not what the agent claims to be doing, but what it actually does. The process census, the credential file opens, the MCP initialisation, the network connections: all of it is visible, all of it is scored, and any of it can be blocked by policy without... - Source: dev.to / 9 days ago
Plinkie is built by Business Data Solutions, a Dutch consulting and training firm that helps organisations put their data to work. This system was built by one person in ten days, runs in two fully separate Google Cloud projects, and costs under $2 per night to operate. The infrastructure is OpenTofu, the services are Python 3.13, and the site is Next.js. - Source: dev.to / 9 days ago
