Windows may warn you the first time
Coral isn't code-signed yet, so Windows may show a blue “Windows protected your PC” screen. Click More info, then Run anyway — the same screen you'd see for most small, independent apps.
Free · Windows 10 / 11 · v1.9.2
Coral is a Windows browser with a workspace built into it.
Your tabs, email, messaging, files, passwords, notes and calendar dock in resizable columns beside the page you are reading — not scattered across eleven windows. And your own assistant — Claude Code, Codex or Gemini — can see the tab you are on, open pages, and work in the panels with you.
- Windows only for now. It runs on 64-bit Windows 10 and 11.
- The installer isn't code-signed yet, so Windows may show a blue “protected your PC” screen. Here's the one click that gets past it.
- The assistant panel uses your own login. Everything else works without one. Why it's yours.
- No account, no telemetry, no paid tier. Nothing is held back for money. What that means.
Good to know
A few honest notes before you download
None of these are dealbreakers — just the handful of things most download pages leave out, so nothing catches you off guard.
Windows only, for now
Coral runs on 64-bit Windows 10 and 11. It leans on Windows for the parts that keep your data on your own machine — the password vault, notifications and file dialogs — so there's no Mac or Linux build today.
The assistant panel uses your own login
Coral doesn't ship an AI service. It runs a CLI already on your machine and talks to it over MCP — your subscription, your account. Pick Claude Code, OpenAI's Codex or Google's Gemini from the selector at the top of the panel, and sign in to it from inside Coral. No terminal, no pasted key.
They aren't identical, and Coral says so where it matters rather than letting you find out the hard way: saved memory, Cowork mode and scheduled Agent Tasks are Claude Code only, and the panel explains why on the spot. Session resume and the Safe / Edits / Full dial work on all three.
The browser is complete without any of them. Tabs, panels, email, calendar, files, passwords and ad blocking all work with no assistant login at all.
Free, all of it
No account, no sign-in, no telemetry, no paid tier — nothing is held back for money. If Coral turns out to be useful there's a coffee button up in the header, but it unlocks nothing, because there's nothing to unlock.
What it does
Your whole workspace, beside the page
Everything here is in the build you can download today — not a roadmap.
Panels that dock, not windows that pile up
Up to five resizable columns hold panels you drag where you want them — Tabs, Files, Email, Social, Messaging, Calendar, Passwords, Tasks & Notes, Terminal, Editor, an API tester and more. Maximise one, minimise the rest, or close them all and use Coral as a plain browser.
Your own assistant, wired into the page
The panel runs your local CLI — Claude Code, Codex or Gemini — with tools scoped by a Safe / Edits / Full dial that Coral enforces itself. Ask what's on the tab you're reading, have it open and navigate tabs, add a task, or check your calendar.
Several accounts signed in at once
Each mail, social, messaging and calendar account gets its own cookie jar, so three Gmails and two X accounts stay signed in side by side — no account-chooser roulette. Profiles separate whole browsing identities.
Several profiles open at once
Open a profile in its own window and work in two at the same time — client and personal, or two of the same site signed in as different people. Each window keeps its own tabs and logins and takes on that profile's colour, while your tasks, notes, bookmarks and saved passwords stay shared. Your windows come back when you reopen Coral.
An ad blocker that is already on
Coral uses the Ghostery blocking engine, on by default across every profile and account — nothing to install, no list to configure. If it breaks a site, the toolbar shield turns it off and tells you how many requests it stopped.
A calendar that is actually a calendar
Local events with full editing, plus any number of ICS feed subscriptions merged into one view, with reminders that fire as real Windows notifications. A calendar account can borrow a mail account's session, so a Google calendar you're already signed into just appears.
One palette for everything
Ctrl + K opens a command palette for the panels, the settings and the things you do often — including “Report a problem”, which writes a scrubbed diagnostic file to your Downloads folder and opens it so you can read it before it goes anywhere.
Bring your own assistant
The built-in panel runs your own Claude Code, Codex CLI or Gemini CLI — switch with the selector at the top of the panel. And because Coral speaks standard MCP, Claude Desktop and other MCP clients can connect from the outside too and drive your real browser — your tabs, your logins, your notes — from their own window. Coral enforces the permission tier, not the assistant, and never hands an outside client arbitrary JavaScript.
Whichever you pick, you still bring your own login to it.
Privacy
Where your data lives
What's true
- No account, no sign-up, no licence check. Nothing identifies you to me.
- No analytics, telemetry or crash reporting. The only thing Coral fetches on its own is its ad-blocking filter list; everything else, you asked it to load.
- Your tabs, bookmarks, notes and calendar live in a file on your own disk at
%APPDATA%\Coral. - Saved passwords are encrypted with Windows DPAPI, tied to your Windows account.
- Separate accounts genuinely don't share cookies, storage or cache — and where two deliberately do, Coral marks them so you're never left guessing.
A few honest limits
The proxy isn't a VPN, and isn't anonymity. Routing through a SOCKS5 endpoint moves your traffic from your ISP's view to the proxy operator's — a change of who can see you, not an absence of anyone.
Separate accounts isolate cookies and storage, not your IP or browser fingerprint. Coral is one person's tool, not audited or signed by anyone else. And history and downloads are shared across profiles — deleting a profile isn't possible yet.
Download
Get Coral for Windows
One installer, per-user, no admin rights needed. It installs to your own user folder and adds a desktop shortcut.
Download Coral 1.9.2Version history & older builds
Your download has started. Two quick things.
- If Windows says “Windows protected your PC”, that's the unsigned-installer notice, not a virus alert. Click More info, then Run anyway. More detail here if you'd rather check first.
- The assistant panel stays empty until you sign in. Pick Claude Code, Codex or Gemini at the top of the panel and sign in there — it happens inside Coral. Everything else works straight away.
That's everything — nothing is held back. If it turns out to be useful, you can buy me a coffee. If not, that's genuinely fine.
If it is useful
You already have everything. This part is optional.
Coral is one person's project — no company, no funding round, no “Pro” tier waiting to appear. Everything on this page is in the free build and stays that way, whether or not anyone ever sends a penny.
If it saves you time, a coffee is a kind way to say so — a one-off, about the size of an actual coffee. Nothing to subscribe to, and nothing about your copy of Coral changes afterwards.
The coffee link isn't set up on this site yet — nothing to click here for now.
Prefer to help without money? Tell me what's broken, or tell someone who would use it. Both are worth more than the coffee.

Ask for something, or tell me what broke
Both forms go to a small database on this site. Email is optional and is only ever used to reply to you. Your IP address is not stored — only a one-way hash of it, to slow down spam.

Questions
The things people actually ask
Is it really free?
Yes. No paid tier, no licence key, no usage cap and no account. If that ever changed it would be dishonest to have written this, so it won't.
Do I need to pay Anthropic to use Coral?
Only if you want the assistant panel on Claude Code, and you pay Anthropic directly, not me. Coral launches the CLI already on your machine, using your own login — and Claude isn't the only option: the panel also runs OpenAI's Codex or Google's Gemini, whichever you already subscribe to. Without any of them you still get a browser with panels, an ad blocker, a calendar, a password vault and everything else — just not the AI panel.
Why does Windows warn me about the file?
Because it isn't code-signed. SmartScreen is saying the publisher hasn't paid to be verified, not that it found anything. Click More info then Run anyway, or.
Will there be a Mac or Linux version?
Not right now. Coral leans on Windows for the password vault and notifications, so a port is real work rather than a build flag. Windows only, for now.
Does Coral send anything anywhere?
It has no analytics, telemetry or crash reporting. It fetches its ad-blocking filter lists, and it loads the pages and accounts you tell it to. Nothing goes to me — there's no server of mine for it to go to.
Is the proxy a VPN? Does it make me anonymous?
No. It routes the app through a SOCKS5 endpoint you supply, which changes who can see your traffic — your proxy operator instead of your ISP — and nothing more. It doesn't hide your browser fingerprint and it isn't anonymity.
Where does Coral keep my data?
In %APPDATA%\Coral on your own machine — the state file, each
account's cookie jar, and the encrypted vault. Saved passwords are encrypted with Windows DPAPI,
which ties them to your Windows user account.
Can I use it with something other than Claude?
Yes, two ways. The panel itself runs Claude Code, OpenAI's Codex or Google's Gemini — pick one from the selector at the top and sign in from inside Coral. Separately, Coral exposes a standard MCP server, so Claude Desktop and other MCP clients can drive your browser from their own window. The permission tier is enforced by Coral, not by the assistant, and running arbitrary JavaScript in your signed-in tabs is never available to an outside client.
The three are not interchangeable: saved memory, Cowork mode and scheduled Agent Tasks are Claude Code only. Coral tells you where a feature isn't available instead of failing when you reach for it.
How do I uninstall it?
Windows Settings → Apps → Installed apps → Coral → Uninstall, like anything else. It installs
per-user, so it never needed administrator rights to get in and doesn't need them to leave. Your
data folder at %APPDATA%\Coral stays behind unless you delete it
yourself.
Who made this?
One developer, for their own use, because no browser did this. It got good enough to be worth sharing. There's no team page because there's no team.
