Running Coral on Windows: A Beginners Setup Guide

8 min readMay 17, 2026

--

So… the “Pirates of the Coral-bean” Hackathon powered by Coral and WeMakeDevs, has been announced with a $10K+ prize pool, people are expected to build crazy AI agents, source connectors, enterprise workflows…

Check out the Hackathon which runs from 25th — 31st May 2026 https://www.wemakedevs.org/hackathons/coral

…and then Windows developers collectively discovered:

“Wait… Coral officially supports only macOS and Linux?”

Pain. Absolute pain.

As someone who primarily works on Windows, this immediately became a problem because:

I wanted to build connectors
I wanted to participate in the hackathon
I did NOT want to dual boot Linux at 2 AM
And I definitely didn’t want 47 Docker + WSL + Ubuntu + ancient Stack Overflow tabs open together

So after spending quite some time building Coral connectors entirely on Windows, I decided to put together a proper guide for everyone else trying to do the same.

Good news?

Coral works perfectly on Windows.
You just need to build it from source.

No WSL required.
No Linux VM required.
No “bro just switch OS” required.

This guide will help you go from:

“coral.exe not found”

to

building AI agents and connectors on Windows like a civilized developer.

What Even Is Coral?

If you somehow landed here before hearing about Coral:

Coral is an open-source platform that lets you query APIs, databases, SaaS tools, files, and services using SQL.

Think:

GitHub
Slack
Cloudflare
Langfuse
Datadog
APIs
Internal tools

…all queryable together.

Example:

SELECT *
FROM github.pull_requests g
JOIN slack.messages s
ON g.author = s.user

And yes, this is exactly why the hackathon is blowing up right now.

The Problem: Windows Isn’t Officially Supported

At the moment:

Coral’s install scripts support macOS + Linux
Official binaries are only released for macOS/Linux
The docs mostly assume Unix systems

Which means Windows developers open the docs and immediately get emotionally damaged.

But here’s the important part:

Coral itself is written in Rust and is cross-platform.

So technically, Windows works fine.

The missing piece is just:

build setup
Rust toolchain
MSVC build tools
a proper guide

That’s exactly what we’re doing here.

What You’ll Need

Before we begin, here’s what Coral needs on Windows:

Microsoft C++ Build Tools

Rust needs MSVC linker + Windows SDK

Rust + Cargo Compiles Coral

Git -> Clone the repo

That’s it.

No black magic.

Step 1 : Install Microsoft C++ Build Tools

This is the step almost every “Windows setup guide” forgets to explain properly.

And then people wonder why cargo build explodes.

Go here:

Microsoft C++ Build Tools

Download:

Build Tools for Visual Studio

Install it

Open Visual Studio Installer

During installation:

Follow this Guide GIF below

Select:

✅ Desktop development with C++

Now IMPORTANT:

Inside installation details, make sure these are checked:

MSVC v143
Windows 11 SDK / Windows 10 SDK (Depends on your TASTE and Machine Ofcourse)
CMake tools
vcpkg package manager

You do NOT need:

C++ ATL
MFC
ancient SDKs from the dinosaur era
14 different compiler versions

Now wait while Microsoft downloads approximately:

“the entire internet”

(roughly 5–10 GB)

Once done:

Restart your machine.

Yes seriously.

Do not ignore this.

Step 2 : Install Rust

Now install Rust from:

Rustup

Run:

rustup-init.exe

Choose:

1) Default installation

Just Press Enter , it is by default

This installs:

stable-x86_64-pc-windows-msvc

Which is EXACTLY what we want.

Verify installation:

rustc --version
cargo --version

If both commands work:
Congratulations.

You are now legally allowed to compile Rust projects.

Step 3 : Install Git

If you already have Git:
skip this section and pretend you’re productive.

Otherwise:

Git for Windows

Install with default settings.

Verify:

git --version

Done.

Step 4 : Clone Coral and Build It

NOW THE FUN PART.

Remember me for faster sign in

Open:

PowerShell
Windows Terminal
or your favorite terminal that makes you feel like a hacker

Run:

git clone https://github.com/withcoral/coral.git
cd coral

cargo build --release --locked -p coral-cli

Now wait.

And wait.

And wait.

And maybe question your life choices slightly. or Touch some grass

The first Rust build compiles hundreds of crates so:
5–10 minutes is completely normal or even 30 Minutes😱Totally Fine !!

Eventually you’ll get:

target\release\coral.exe

AND THAT’S THE MOMENT.

You now officially have Coral running on Windows 🎉

Step 5 : Add Coral to PATH

You probably don’t want to type:

.\target\release\coral.exe

for the rest of your existence.

So let’s add it to PATH.

Create a local bin folder:

New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.local\bin"

Copy Coral:

Copy-Item "target\release\coral.exe" "$env:USERPROFILE\.local\bin\coral.exe"

Then add this to PATH:

C:\Users\<YourUsername>\.local\bin

Let me make it more easy to set the environment variables

Copy the Path to your ‘coral.exe’ release from the bin folder , i.e in my case `C:\Users\Jishanahmed Shaikh\.local\bin`
Open “Run” from Start / Press Win + R, type sysdm.cpl

Click on Environment Variables
Click on Path

Click on New

Now Add your Copied Path, i.e in my case “C:\Users\Jishanahmed Shaikh\.local\bin”

Click on Ok on all Dialog Boxes

Open a NEW terminal and run:

coral --version

If it works:
you win. I win. we all win

Step 6 : Run Coral Onboarding

Now initialize Coral:

coral onboard

This walks you through connecting your first source.

GitHub, APIs, connectors, whatever you want to use.

Credentials are stored locally inside:

AppData\Roaming\coral\

Step 7 : Test MCP Server

This is important if you’re building:

AI agents
Coral Intelligence integrations
MCP workflows
hackathon projects

Run:

coral mcp

If it starts without errors:
you’re good.

That means the MCP transport is functioning correctly.

Lets Talk about Errors Now

Common Windows Errors (AKA Character Development)

`link.exe not found`

This means:

Build tools weren’t installed properly
OR machine restart was skipped
OR PowerShell is confused spiritually

Usually reinstalling Build Tools + restarting fixes it.

OpenSSL Errors

Rust developers see OpenSSL errors so often it’s basically a personality trait now.

Thankfully Coral’s setup already includes vcpkg support.

Use:

vcpkg install openssl:x64-windows-static-md

Then retry build.

Why This Matters for the Hackathon

A LOT of developers participating in the Coral Hackathon might be Windows users.

And many would assume:

“Oh Coral doesn’t support Windows yet, guess I can’t participate.”

That’s not true.

You absolutely can:

build connectors
build AI agents
contribute to Coral
participate in the hackathon
run MCP workflows
build locally

…entirely from Windows.

Hopefully official Windows binaries arrive in the future.

But until then:
this setup works beautifully.

Final Thoughts

Honestly?

The funniest part is:
after setup, Coral behaves almost identically to Linux/macOS.

The hardest part is just getting through the initial Windows tooling setup.

Once done:
everything feels normal.

So if you’re a Windows developer staring at the Coral Hackathon thinking:

“Maybe I’ll skip this one…”

Don’t.

Your OS should not stop you from building cool things. We can build anything

Useful Commands

# Build Coral
cargo build --release --locked -p coral-cli

# Verify installation
coral --version# Connect data sources
coral onboard# Run SQL queries
coral sql "SELECT * FROM github.pulls LIMIT 5"# Start MCP server
coral mcp

Hope this guide helps whoever intends to Build with Coral from Windows
