// SETUP
Three steps. A few minutes.
Connect Vortex, open a PR, and get reviews on every push. Full walkthrough →
$ step.1
Sign in & connect GitHub
Create your Mergestorm account with Google or GitHub. No credit card required to start.
$ step.2
Deploy Vortex
On Automation, install the Vortex GitHub App on the repos you want reviewed — one install, same as other PR review tools.
$ step.3
Open a pull request
Vortex reviews on every push. Cyclone auto-patch is optional later in Settings if you want fixes committed for you.
// BEHIND THE SCENES
How the Mergestorm feedback loop works
It is not magic. Vortex reviews on every push; Cyclone can patch when you opt in later.
Vortex reviews
On every open PR and push, Vortex posts inline comments and a check run — a fast first pass on what changed.
Cyclone fixes
When auto-patch is on, Cyclone takes actionable findings from those reviews and commits fixes straight to the PR branch.
The loop continues
New commits trigger another review pass and another round of fixes. That back-and-forth is the Mergestorm feedback loop.
Manual trigger too
Comment @mergestorm-vortex review on any PR when you want an on-demand pass. Auto-fixes stay off until you enable them.
// STORM AGENTS
Review and fix on autopilot
Start with Vortex for reviews. Add Cyclone later if you want auto-patch — it is never required to get value from Mergestorm.
