Comet alternative
Comet is a Chromium browser built around Perplexity’s assistant, so using it means moving into it. Browsentic adds an agent to the browser you already have, with your profile, logins and extensions as they are.

| Browsentic | Comet | |
|---|---|---|
| The shape of it | ||
| What you install | An extension and Browsentic Bridge, in the browser you use now | A second browser, then your profile into it |
| Your logins | Already there: it drives the tab in front of you | Imported, then maintained in a second place |
| Where the agent runs | On your machine, started by Browsentic Bridge on loopback; the model is your agent’s own provider | Perplexity’s cloud |
| The agent | Claude Code, Codex, Antigravity, Mistral Vibe, Grok Build, Cursor CLI, Qwen Code or OpenCode, your pick, down to the model | Perplexity’s models |
| What it costs | Nothing beyond the agent subscription you already have | A free tier, Pro at twenty dollars a month, Max at two hundred |
| Source | Apache 2.0 licensed, source available | Proprietary |
| If it is discontinued | It is yours: the source, Browsentic Bridge and the extension are on your disk | The browser is the product |
| On the page | ||
| Read, click, type, submit | Yes, and anything consequential asks first | Yes |
| Console and network | Yes: errors, failed requests and timings, over Chrome’s debugger | Not exposed |
| Credentials | Sealed into placeholders; the agent never sees plaintext | Handled by the browser’s own password manager |
| Show it a job once | Recordings: do it yourself, later say “do it like last time” | Describe it again each time |
| Site knowledge | Site maps: it explores any site and keeps notes, intranets included | None kept between tasks |
| Search | None of its own: it drives the pages you already use | An answer engine, and the reason many people install it |
| While you are elsewhere | ||
| Scheduled jobs | Kept by Browsentic Bridge, on your machine | Background assistants, on the Max plan |
| Several agents at once | One conversation per tab, several running at once, through one Bridge | One assistant |
| Voice | Dictation in the panel, and hands-free voice in Chromium browsers | Voice mode |
| Mobile | Drives Chrome on an Android phone from your desktop (experimental); no app on the phone | iOS and Android apps |
Browsentic only
An AI browser asks you to bring your profile, extensions, passwords and sessions into it. Browsentic works in the browser you already use, so there is nothing to move.
It runs on the CLI you already have, and switching between eight agents is one click. No second subscription, and no dependence on one vendor staying in the browser business.
Atlas shut down in August 2026 and took its browser with it. Browsentic is Apache 2.0 and runs on your machine, so the worst case is that it stops getting updates.
Passwords, keys, tokens and card numbers become sealed placeholders before the agent sees them, and turn back into plaintext only inside the field they are typed into.
Record a job yourself and replay it later. Point it at a site and it maps itself. Both become skills you read before you arm them, and both work on an intranet no model has seen.
Browsentic Bridge also serves MCP over stdio, so Claude Code, Cursor or Zed can drive the paired tab the side panel uses.
Comet only
Some of these are good reasons to choose Comet.
Search, ad blocking, voice and a built-in sidebar. Browsentic has none of that: it is a side panel in the browser you already chose.
Comet installs like any browser. Browsentic has two parts, Browsentic Bridge on your computer and the extension from a browser store. One line installs the Bridge and opens the store page, but you still press Add there.
Perplexity’s search is the reason many people use Comet, and it is good. Browsentic does not search: it drives the pages you open yourself.
Comet runs on iOS and Android as an app of its own. Browsentic needs a desktop browser and Browsentic Bridge on the same machine. From there it can drive Chrome on a plugged-in Android phone, but there is no Browsentic app to carry around.
The short version
Pick Comet if you want an AI browser: search, a sidebar and voice in one download, on desktop and mobile, and you are happy to switch browsers.
Pick Browsentic if you want to keep the browser you have, run the agent you already have, keep the whole thing on your machine, and own the source.
They can coexist, though there is little reason to run both. If you are trying Comet, Browsentic will drive it too: it is Chromium, so the extension loads.
Free and open source under Apache 2.0, with no API key, subscription or account. One line installs Browsentic Bridge and opens the extension’s store page. Nothing connects until you pair the two.
