ReviewGate vs Cursor BugBot

BugBot is Cursor's cloud reviewer: it scans GitHub PRs and leaves bug-finding comments, tightly integrated with the Cursor editor workflow. ReviewGate is a self-hosted CLI gate that reviews any git diff with the model you choose and returns a verdict CI can act on. Both are built for the same reality — AI writes a lot of the code now — but they sit at different points in the pipeline.

At a glance

Capability ReviewGate Cursor BugBot
Deployment / data residency Self-hosted CLI; diffs go only to your configured LLM endpoint Cloud service; code processed on Cursor's side
LLM provider choice Any OpenAI-compatible or Anthropic endpoint Vendor-managed models
Where it runs Anywhere git runs: local pre-push, GitHub, GitLab, air-gapped CI GitHub PRs
Output form BLOCK / WARN / pass verdict + exit codes (0/1/2) for CI gating PR comments; "Fix in Cursor" hand-off to the editor
Review dimensions Parallel security / logic / perf / AI-smell dimensions + optional intent review against acceptance criteria Bug hunting focus
Incomplete review handling Timeout / oversized diff → WARN + explicit incomplete marker; never a fake PASS No public incomplete-review contract
Pricing model MIT open source; pay only your LLM usage Part of Cursor subscription / usage
Public evaluation logs Raw runs committed under docs/evals/ Not public

When BugBot is the better fit

When ReviewGate is the better fit

Different layers, not enemies

BugBot optimizes the developer's inner loop: find a bug in the PR, jump to Cursor, fix it. ReviewGate optimizes the merge boundary: decide, with auditable confidence handling, whether this diff should be allowed in at all — and refuse to pretend an unfinished review passed. If your policy allows a cloud reviewer, running BugBot for feedback and ReviewGate as the final CI gate is a coherent combination.
