CodeRabbit reviews the pull request.
Rotwise fixes the repository.

The short version

CodeRabbit is an AI reviewer for pull requests. Install it on GitHub, GitLab, Bitbucket or Azure DevOps and it reviews every pull request when it is opened and again on every commit pushed to it: comments with one-click fixes, an agentic chat, linter and SAST results, and learnings that carry your team's conventions from one review to the next. It also reviews from the IDE and the command line before you push, and on the higher plans it ranks the pull request queue by value and risk and reviews every pull request for security. If your problem is the flow of new pull requests, CodeRabbit is built for exactly that and this page will not try to talk you out of it.

Rotwise starts from the other end. It does not review pull requests at all. It clones the whole repository, scores the technical debt AI assistants leave behind, ranks the findings, and turns them into small pull requests that a human approves one batch at a time. If your product was written largely with Cursor or Claude Code, you have one to ten engineers, and the question on the table is "what is already wrong in here, what do we fix first, and who is going to do it", Rotwise was built for that question.

Side by side

Where CodeRabbit is the better choice

• You need a reviewer, not a backlog. Every pull request reviewed the minute it opens and again on every push, fixes you apply with one click, and a reviewer that learns the conventions you correct it on. Rotwise reviews nothing on the way in. It works on the debt that is already in the repository.
• Your team is bigger than its founders. Ten engineers opening pull requests all day need triage of the queue, custom pre-merge checks, post-merge actions and the Jira and Linear integrations. That is what the Team plan sells, and Rotwise has no equivalent.
• You host on GitLab, Bitbucket or Azure DevOps, or your stack is outside seven languages. CodeRabbit reads any language on any of the four hosts. Rotwise is GitHub-only and reads Ruby, JavaScript, TypeScript, Python, Go, Rust, and PHP.
• Compliance is the deliverable. Custom roles, SSO, audit logging, a self-hosting option and an SLA are Enterprise plan features at CodeRabbit. Rotwise has none of them.

Where Rotwise is the better choice

A pull request reviewer sees the diff in front of it. The forty thousand lines an assistant generated before you installed anything never come up for review, and neither does the pull request that merged them three months ago. CodeRabbit sells full codebase scans separately, on usage-based pricing, as part of its security product. For Rotwise, the scan of the whole repository is the product, and it covers eight categories of debt, not only security.

• The debt is already merged. Rotwise reads every file in the repository, not the changes since Tuesday: the route that never had an auth check, the key pasted from a dashboard in the first week, the query inside a loop that was fine with ten users. It finds what was there before anyone was reviewing.
• Order, not volume. Every finding is scored by severity and category, then sequenced: security, correctness, tests, performance, configuration, maintainability. The first batch is the one that would embarrass you on a diligence call, not the longest one.
• Fixes arrive as pull requests you approve. An approved batch becomes one branch, one pull request and one commit per finding, so a single revert undoes it. You see the dry-run diff before approving anything, and you decide when to merge. One batch, one pull request, one revert explains why the batches stay small.
• Priced for a small team, and honestly. For a solo founder, CodeRabbit Essentials at $24 a month billed annually costs less than Rotwise Indie at $49. You are buying different things: a reviewer for the pull requests you open from now on, or a scan and fixes for the 25,000 lines you already have. Rotwise charges one flat price per plan with a line cap and no per-seat pricing, and the free scan needs no card and shows you the score before you pay for anything.

What a batch looks like

An illustrative example from a Next.js app. A scan flags a route handler that returns every invoice in the database to whoever asks:

// app/api/invoices/route.ts
import { NextResponse } from "next/server";
import { db } from "@/lib/db";

export async function GET() {
  const invoices = await db.invoice.findMany();
  return NextResponse.json(invoices);
}

Rotwise reports it as a P0 security finding, "API handler route.ts has no visible auth check", because nothing in the file reads a session, a token or an Authorization header before doing its work. The finding goes into the first batch with the other P0 and P1 findings from the scan, and the proposed fix verifies the caller and scopes the query to them:

// app/api/invoices/route.ts
import { NextResponse } from "next/server";
import { auth } from "@/auth";
import { db } from "@/lib/db";

export async function GET() {
  const session = await auth();
  if (!session?.user) {
    return NextResponse.json({ error: "Unauthorized" }, { status: 401 });
  }

  const invoices = await db.invoice.findMany({ where: { userId: session.user.id } });
  return NextResponse.json(invoices);
}

A reviewer would have caught this on the pull request, if there had been a pull request. There was not: the route was generated in a chat window and pushed to main with two hundred other files. The diff is checked with git apply --check before you see it, lands on a branch named after the batch, and nothing merges until a human merges it. Next.js API routes with no authentication: find and fix them walks through the pattern in detail.

Using both

Many teams should. CodeRabbit on every pull request your team opens from now on, so new problems are caught while the diff is small. Rotwise for the code that was already there when you installed it, delivered as pull requests you merge between features. The two meet on the pull request: a Rotwise batch is an ordinary pull request against your default branch, so CodeRabbit reviews it like any other and you get a second opinion on the fix before you merge.

If the tool you are weighing is a static analysis platform rather than a reviewer, Rotwise vs SonarQube covers that. How Rotwise handles your code along the way, including the permissions the GitHub App asks for, is on the security page.
