BugViper: AI Code Review with Codebase Awareness

BugViper is a GitHub App that performs AI-powered code review on every pull request. Unlike tools that only read the diff, BugViper clones your repository into a secure E2B sandbox, builds a real-time call graph with tree-sitter to understand which functions and files are affected by each change, then dispatches codebase-aware DeepAgents to find bugs, security issues, and performance problems before they merge. Results arrive as inline PR comments, a structured review summary, and persistent issue tracking — all visible in the BugViper dashboard.

What BugViper does

Feature	Description
🤖 AI DeepAgents	Codebase-aware agents that understand cross-file function interactions, not just isolated snippets
🫡 Normal Mode	Single generalist agent — fast, efficient reviews for everyday PRs
🔬 Deep Mode	Three specialized sub-agents (correctness, security, performance) run in parallel for thorough analysis
🏝️ E2B Sandboxes	Secure isolated sandboxes to clone and review code — no access to your environment
🔍 Blast Radius + Call Graph	Builds a call graph on the fly so agents see the real impact of every change
🔧 Static Analysis	ESLint, Ruff, golangci-lint — fast lint-only mode with support for Python, JS/TS, Go, and more
✅ Verifier Pass	Validates every finding against the actual diff — removes false positives and classifies issues as `nitpick`, `valid`, or `outside_diff`
🔀 Dedup	Deduplicates findings across batches and agents so the same issue is never reported twice
🧠 Any LLM Model	Use any model — open source or closed source — via OpenRouter, Gemini, or MiniMax
💬 Inline Comments	Posts high-confidence issues directly on the relevant lines in the PR
📊 Analytics Dashboard	Tracks bugs caught, resolved, merge times, and PRs reviewed per day
🔁 Resolve Detection	Automatically marks issues as `fixed` when the same issue no longer appears in a subsequent PR
📈 Per-Repo Analytics	Stacked bar charts per repo for reviews per day, PRs reviewed, average merge time, and addressed rate
🐛 Issue Lifecycle	Full issue tracking — open, resolved, fixed — with per-issue GitHub comment linkage

Coming soon

BugViper is actively developed. The following capabilities are in progress and will be available in future releases.

Global Knowledgebase — Agents will learn from review feedback across all repos so common patterns get smarter over time.Repo Knowledgebase — Per-repo memory so agents remember past issues and avoid re-reporting the same findings.More Static Analysis Tools — Hadolint (Dockerfile), ShellCheck, and Terraform (HCL) support are on the roadmap.
