# Codeward vs CodeRabbit

> Both review pull requests. One reads the diff. The other runs the code.

CodeRabbit is a fast AI reviewer. Codeward boots a sandbox, runs real analysis tools, and verifies its fixes before it suggests them.

## The short version

Use CodeRabbit if you want an AI to summarize every PR and leave line-by-line feedback, and you already have separate tools for security and tech debt. Use Codeward if you want a PR check that executes code in an isolated sandbox, scores 122 debt, security and compliance checks, and can block a merge on a confirmed critical finding.

## What CodeRabbit does

Summaries, walkthroughs, diagrams, line comments, and chat about the diff. Learns from your feedback.

## What Codeward does

Guardian agent plus 8 analyzers. Sandbox execution, Tree-sitter AST analysis, Trivy and OWASP ZAP, verified fixes, merge gating.

| Feature | CodeRabbit | Codeward |
| --- | --- | --- |
| PR summaries and walkthroughs | ✔ (with diagrams) | ✔ |
| Line-by-line PR comments | ✔ | ✔ with suggested diffs |
| Chat with the reviewer about the diff | ✔ | ✔ (Chat agent with run-log access) |
| Executes your code in an isolated sandbox | Static and AI analysis, plus linters/SAST integrations | ✔ ephemeral microVM per run |
| Verifies a fix before suggesting it | ✕ | ✔ tests patch in sandbox |
| Flaky test detection | ✕ | ✔ 10× rerun |
| Hard merge block on critical findings | ✕ comments and status | ✔ deterministic policy |
| Technical debt health score and trend | Limited | ✔ repository health matrix |
| Compliance checks (EU AI Act, GDPR, WCAG) | ✕ | ✔ 10 checks |
| AI-era risks (prompt injection, PII in LLM context) | ✕ | ✔ 18 checks |
| Unit test and docstring generation | ✔ | ✕ not a focus |
| Learns from natural-language feedback | ✔ | ✕ |
| GitLab support | ✔ GitHub and GitLab | GitHub today, GitLab on roadmap |
| Self-host, open source | ✕ | ✔ Apache 2.0 |
| SOC 2 Type II | ✔ | Not yet published |

## Honest take

CodeRabbit is the more mature product for pure PR conversation. It supports GitHub and GitLab, learns your team's preferences, and generates tests and docstrings. If your pain is slow human review, it addresses that well.

Codeward targets a different pain: code that *looks* fine in a diff but fails when run, or debt that never shows up in a single PR. Because it executes code and runs tools in a sandbox, it can catch runtime and flaky-test failures a diff-only reviewer can only guess at.

Pick by problem: faster reviews of diffs, or a gate that checks what actually happens when the code runs.

## Pricing

CodeRabbit: free for open-source repos; paid plans from about $24 per developer per month on annual billing, with higher tiers above that and usage-based overage per reviewed file. Codeward: open source and self-hostable at no license cost; managed cloud pricing, see [codeward.cloud](https://codeward.cloud).

## Frequently asked questions

### Is Codeward a CodeRabbit replacement?

If you only want AI summaries and comments on PRs, CodeRabbit does that well. If you also want sandbox execution, security and debt checks, and merge gating, Codeward covers more of that ground. Some teams run both.

### Do I need to connect my own repository?

Yes. Codeward installs as a GitHub App and clones the repo into an ephemeral sandbox so it can parse the full AST. GitLab and Bitbucket are on the roadmap.

### Are both tools secure?

Both take security seriously. CodeRabbit publishes SOC 2 Type II. Codeward runs untrusted PR code only inside ephemeral sandboxes that are destroyed after each run, and you can self-host the whole stack.
