Two readings on one pull request: Copilot code review doing its review, and Aevral, through its PR review, live on install, adding its security reading.
| Row | Copilot code review | Aevral |
|---|---|---|
| Question it answers | How can this pull request improve? | Who has access to what, and does this change widen it? |
| Stated job | Reviews pull requests for bugs, quality, and security issues | Security reading of the PR diff: access control, business logic, injection, XSS, SSRF, path traversal, LLM integration |
| Where it runs | In the GitHub pull request, per GitHub's docs | GitHub Check and inline comments, live on install |
| Unit of work | The review comment and suggested fix | Up to five findings per review, grounded on the added lines |
| Complementary? | Yes | Yes |
Copilot code review runs where you already merge: it reviews each pull request for bugs, code-quality issues, and security issues, and suggests fixes in the GitHub UI. Aevral is built for a security reading of the diff: whether it widens who has access to what, or carries injection, XSS, SSRF, path traversal, or LLM-integration flaws. Good code and safe access are separate properties; a change can read well while moving the other.
With Aevral's PR review, live on install, the two reviews sit side by side on the same pull request: Copilot code review doing the review it states, and Aevral adding its security reading. Aevral also reads the repository snapshot at rest, for access control and business logic only. This page keeps the framing complementary; it makes no claim about results on your pull requests.
Copilot
GitHub Copilot code review is GitHub's built-in AI reviewer. It reviews pull requests for bugs, code-quality issues, and security issues, and suggests fixes directly in the pull request.
Aevral
Security review, handled. PR review, live on install, looks for access control, business logic, SQL and command injection, XSS, SSRF, path traversal, unsafe deserialization, token and session flaws, and LLM-integration risks on the diff. Paid PR plans are live in the console. The whole-repo scan is live and self-serve, and reads authorization, IDOR, and business-logic access control only. A finding is a lead with evidence, and a human decides. No patches are auto-applied.
This change adds a listing endpoint so a teammate can debug user reports, copied from an existing route and mounted without a guard. The code is valid, it works, and it is genuinely useful.
export async function GET() { const users = await db.users.list() return Response.json(users)}The route works, which is the problem: it has no authorization gate at all, and it returns every user row. New route, no gate, sensitive data, production mount. Aevral is built to read an added route for the access question first: who can call this, and what do they get.
Keep Copilot code review for bugs, quality, and security on every pull request; run Aevral for its security reading of the same diff, live on install.
No. Copilot does its stated job and keeps doing it. Aevral runs alongside it with its own reading: its PR review, live on install, looks for access control, business logic, injection, XSS, SSRF, path traversal, and LLM-integration security on the pull requests it reviews, and its whole-repo scan reads access control and business logic across the repository at rest.
No. This page states each product's job and shows one worked example of Aevral's own reading. Results on your code depend on your code; evaluations belong to you.
Aevral is self-serve: install the GitHub App and log in to the console. The waitlist form is a launch-updates channel; joining does not reserve a price, access, or a contract.
