Two readings on one pull request: Bugbot doing its review, and Aevral, through its PR review, live on install, adding its security reading.
| Row | Cursor Bugbot | Aevral |
|---|---|---|
| Question it answers | What problems does this change carry? | Who has access to what, and does this change widen it? |
| Stated job | Flags likely bugs, quality problems, and security issues on the PR | Security reading of the PR diff: access control, business logic, injection, XSS, SSRF, path traversal, LLM integration |
| Where it runs | The Cursor workflow and the GitHub pull request, per Cursor's docs | GitHub Check and inline comments, live on install |
| Unit of work | The review flag on the change | Up to five findings per review, grounded on the added lines |
| Complementary? | Yes | Yes |
Bugbot is built to review the change itself: likely bugs, quality problems, and security issues, in the Cursor workflow, before merge. Aevral is built for a different reading: whether this diff breaks access control or business logic, or carries injection, XSS, SSRF, path traversal, or LLM-integration flaws. Those are different readings of the same change, and a change can look clean while quietly redefining access.
The framing is addition, not replacement: Bugbot doing the review it states, and Aevral adding its security reading, side by side on the same pull request with Aevral's PR review, live on install. Aevral also reads the repository at rest, for access control and business logic only. This page makes no claim about results on your code.
Bugbot
Cursor Bugbot is an AI code reviewer. It reviews each pull request and flags likely bugs, code-quality problems, and security issues before they merge.
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 removes the server-side check on coupon usage, because the new frontend already validates the cap before submitting. The code is clean and the redemption flow works exactly as designed.
export async function POST(req: Request) { const { cart, code } = await req.json() if (coupon.uses >= coupon.maxUses) throw new Exhausted() return applyDiscount(cart, code)}The client validates nothing that matters: callers are not the client. With the server check gone, the usage cap is advisory, and any caller can redeem past the limit. The program still runs exactly as designed, and the rule behind it is gone, which is the class Aevral reads for: a change that keeps the feature working while quietly removing the control.
Keep Bugbot for problems in the change on every pull request; run Aevral for its security reading of the same diff, live on install.
No. Bugbot 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.
