Devolyn

Download

Deploy Devolyn Guard on your own host.

Three ways to get the same self-hosted stack. Pick the one that matches how much you want to inspect before you run it.

  1. 01  /  One command

    Run the installer

    Fetches the setup script and runs it. About five minutes on a fresh host. Docker is installed for you if it is missing.

    $ curl -fsSL https://get.devolyn.com | bash

  2. 02  /  Setup script

    Download, read, then run

    The same script the one-liner runs, as a file you can read first.

    devolyn-setup.sh
    chmod +x devolyn-setup.sh
sudo ./devolyn-setup.sh

  3. 03  /  Source

    Tarball and checksum

    For the security-conscious: the full source archive with a SHA-256 checksum to verify before you extract.

    devolyn-guard.tar.gzdevolyn-guard.tar.gz.sha256
    sha256sum -c devolyn-guard.tar.gz.sha256

What it sets up

A complete stack on one host.

  • Docker Engine and Docker Compose, if they are not already installed
  • The Devolyn Guard services: verification API, dashboard, PostgreSQL and Redis
  • An nginx reverse proxy with TLS termination in front of the services
  • The append-only, hash-chained audit trail and its integrity checks
  • Health-gated startup, so the stack only reports ready when every service is

Requirements

Linux host with sudo.

Host
A Linux server or VM you administer
Privileges
sudo, to install Docker and bind the proxy ports
Docker
Installed automatically if it is missing
Network
Outbound access during install only; nothing is sent to Devolyn afterwards

Signed native installers for Windows & macOS coming soon.

After install

Then wire it to your repo.

The quickstart walks through connecting Guard as a CI status check and, optionally, as a real-time hook.
