Custom rules (Kodus)
– Natural-language policies applied at the repo, folder, file, or even a specific PR level.
If you’re trying to decide which AI should review your team’s PRs, this benchmark will help. We put Kodus and GitHub Copilot side by side, focusing on what actually impacts engineering work: review depth, customizable rules, external context, metrics, and the freedom to choose the model and how you run it.
– Natural-language policies applied at the repo, folder, file, or even a specific PR level.
– Pull CI results, Jira/Linear issues, Notion specs, tests, logs, scripts... all unified in a single review comment.
– Native VS Code/JetBrains integration to review changes before you push.
– A panel that shows what shipped to production plus an automatic backlog of ignored suggestions, organized by severity and category.
– Use your own API key and run whichever model makes the most sense for your team (OpenAI, Gemini, Claude, etc.).

To evaluate real-world performance, we compared Kody and GitHub Copilot reviews across several PRs from projects like Sentry, Cal.com, Grafana, Discourse, and Keycloak.

Use any model you want — and keep every review fully under your control.
Run with your own API keys — GPT-5, Claude, Gemini, or any model you choose.
Locked to a single provider — no model choice or cost control.
Version-controlled guidelines you can scope from the whole repo down to a single file — or import ready-made in one click.
Granular, version-controlled rules for any file, folder or PR, with a one-click community library ready to import.
A single ruleset per repo or branch. You only control when Copilot reviews. No natural-language code rules, no library, and no file or folder-level granularity.
If your team values precision, visibility, and control, Kodus is the most complete choice. It allows you to:
GitHub Copilot works well for teams that want something simple and fully managed. You turn it on and that is it, it comments on PRs, generates summaries, and helps directly in the IDE. But it stops there. There are no structured rules by file or PR, no automatic backlog of suggestions, no deep quality metrics, and no option to run outside GitHub’s cloud.
For teams looking for convenient plug and play inside GitHub, Copilot does the job. But if you want real customization, deep context, and the freedom to run however you prefer, Kodus gives you more without locking you into anything.
No, they are two features inside the same Copilot subscription. Inline completions ship in your IDE as you type. Code review is a separate PR-time feature that GitHub runs against pull requests on demand or automatically. Both are bundled with the Copilot Pro, Pro Plus, Business, and Enterprise plans. The Copilot Free plan does not include code review.
Kodus Teams is $10 per developer per month monthly or $8 annual prepay, plus your own model bill (BYO LLM). GitHub Copilot Business is $19 per user per month with code review bundled in; Copilot Enterprise is $39 per user per month. Both Copilot tiers include code review across all repos that the org has activated. Kodus self-hosted is free under AGPLv3 if you want zero per-seat cost. Starting June 2026, Copilot code review runs consume GitHub Actions minutes.
Kodus yes, full BYO LLM. Point three env vars at OpenAI, Anthropic, Gemini, Groq, Cerebras, vLLM, Ollama, or any OpenAI-compatible endpoint. GitHub Copilot routes through their internal model selection (default GPT-5 family, with Anthropic Claude as an option on some plans). You cannot route Copilot at your own provider key.
Both do. Kodus uses markdown files in .kody/rules/ with YAML frontmatter (scope, path globs, severity) plus plain-English instructions. Kodus also auto-detects .cursorrules, CLAUDE.md, .windsurfrules, and .github/copilot-instructions.md as rule sources. GitHub Copilot reads custom instructions from .github/copilot-instructions.md directly and supports Copilot Memory on Pro and Pro Plus for repository-specific learned context.
GitHub Copilot code review only reviews pull requests on GitHub.com and GitHub Enterprise Server / Enterprise Cloud. It does not work on GitLab, Bitbucket, or Azure DevOps. Kodus runs on all four (GitHub, GitLab, Bitbucket, Azure DevOps) plus the self-managed variants of each.
Kodus self-hosted is free under AGPLv3 and runs with Docker Compose. Source code, LLM calls, and review history stay on your infrastructure. GitHub Copilot is a SaaS-only product. You can use it inside GitHub Enterprise Server, but the model calls still leave your perimeter to GitHub-managed infrastructure.
When you already have Copilot for inline IDE completions and want PR review as a separate signal. Copilot review acts on PRs you assign to it; Kodus runs automatically on every PR with your policy rules enforced. Many teams use Copilot for the IDE loop and Kodus for the PR loop because the latter ships customizable rules, metrics dashboard, technical-debt backlog, and self-host. They are not mutually exclusive.
