Coterie How to install
Getting started · b 0.1.3
Install Coterie on Windows, connect the coding agents you already use, and start your first project.
01 · Get ready
You need Windows 10 or 11 (64-bit), git, and at least one supported coding CLI installed and signed in. Provider subscriptions and usage are separate.
02 · Download & install
Coterie is new. For now, the beta installer is unsigned to keep development costs down. This is a temporary limitation of the early beta, and Windows may not yet recognize each new release.
If you downloaded Coterie from this official site and decide to continue, choose More info, then Run anyway, when those options are available.
These are labels in the Windows prompt, not buttons on this page. “Unknown publisher” is expected for this unsigned beta.
That can be a different protection. Smart App Control can block an unsigned app outright and does not offer an exception for one app.
Some managed PCs also prevent continuing past SmartScreen. If Windows does not offer a way to proceed, stop here: this beta may not run under your device’s current policy.
You do not need to switch off Defender or your PC’s protections to follow this guide. Read Microsoft’s explanation
Already past the Windows prompt? Follow the installer, then open Coterie from the Start menu. Only continue with files downloaded from this site.
03 · Make it yours
Pick a language, appearance and level of detail. The welcome guide walks you through the rest.
Coterie detects the supported CLIs on your PC. Complete their own installation and sign-in if needed.
Open a test repository, describe a small goal and check the proposed plan before starting work.
A little context
It may. SmartScreen builds reputation from download history and other signals, including whether the file is signed. Microsoft does not publish a guaranteed download threshold or timetable. An unsigned update must build reputation again for its new file.
For the moment, we are keeping early development costs down rather than paying for a Windows code-signing certificate. This is a temporary beta limitation, not a subscription you need to buy. We will keep this guide up to date as distribution changes.
Use the update notice in the app when a new version is available. You can update from earlier betas and keep your projects and settings.
No. One supported CLI is enough to start. You can connect more later. Their subscriptions and usage limits remain separate from Coterie.
