Vortex and Cyclone, working in real time

This feed is live — not a replay. Every line is Vortex reviewing pull requests or Cyclone applying patches as it happens across Mergestorm, refreshed every few seconds.

  • Vortex — reviews and check runs
  • Cyclone — auto-patches on PR branches

// 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 Agents, 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 for auto-patch and Tempest for deep systemic passes when you need them — Vortex alone is enough to get value.

Code review

Meet Vortex

Vortex

Repo-aware PR reviewer. Reads your codebase, diff, and linked GitHub Issues when the PR closes a ticket — then posts inline comments plus a GitHub check on every push.

  • Repo-aware passes
  • Linked issue context
  • Inline on every push

Auto-fix

Meet Cyclone

Cyclone

Optional auto-patch agent. Takes actionable fixes from Vortex review comments and commits them to the PR branch when you enable auto-patch — not required to start reviewing.

  • Optional add-on
  • Fixes from reviews
  • Opt-in in Settings

Deep review

Meet Tempest

Tempest

Deep systemic review for hard PRs — cross-file contracts, config drift, and architecture. On-demand when a push-by-push Vortex pass is not enough.

  • Systemic pass
  • Cross-file contracts
  • On-demand deep review
