Automated Code Review

Catch critical issues
before they reach production

Buggers automatically reviews your pull requests, detects bugs, security risks, and code quality issues — so you can ship with confidence.

CODE REVIEW & REGRESSION PROTECTION

Deterministic PR triage with whole-repo context

Buggers inspects the raw unified diff against historical fault lines. In-process scanners catch side-channel timing flaws, plaintext secrets, and SQL injections in 140ms before synthesising AST-grounded patches.

INTELLIGENCE & VOLATILITY ENGINE

Eliminate phantom alerts with AST-level signals

Generic LLM wrappers hallucinate phantom line numbers and suggest libraries you don't even have installed. Buggers correlates modified functions with your real git commit history, defect frequency, and coverage deltas to score real regression risk.

CI / CD & MERGE GATES

Enforce quality gates with declarative repository rules

Define review thresholds with a simple .buggers.yml in your repository root. Set GitHub check runs to automatically block pull request merges when critical severity findings or high risk are detected.

Required Check

FIG 0.1

Instant Webhook

PR openings and pushes trigger AST evaluation via HMAC-verified webhooks without poll delays.

FIG 0.2

Commit Churn

Correlates changed functions with past rollback commits and defect density in that file.

FIG 0.3

Risk Scoring

Deterministic 0-100 score weighing cyclomatic complexity, test delta, and mutation paths.

FIG 0.4

Grounded Fixes

AI remediations cite real diff line numbers only. Hallucinated file paths are discarded.
