The verdict: can you vibe code Bito?
You can build a personal subset that indexes a single local repository and serves context over MCP, but replicating Bito's multi-repo enterprise knowledge graph and automated PR review fleet requires serious engineering.
Bito bridges scattered engineering silos into a unified knowledge graph. While a solo developer can spin up a Next.js frontend and a basic vector search pipeline over a single git repo in a weekend, building an incremental AST parser that maps cross-service dependencies across multiple repositories, handles GitHub webhook queues reliably, and exposes a performant Model Context Protocol (MCP) server is a substantial undertaking. The enterprise compliance layer (SOC 2, zero data retention) is entirely out of reach for a personal clone.
Estimated effort: 4-6 weeks of focused development
What you can't replicate
- SOC 2 Type II enterprise compliance certification and zero code retention architecture
- Native enterprise connectors for Jira, Confluence, and self-hosted GitLab/Bitbucket instances
- Battle-tested scale processing tens of thousands of weekly enterprise pull requests

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js project with Tailwind CSS, configure Supabase with pgvector extension, and set up better-auth for personal dashboard access.
Create a new Next.js TypeScript project using App Router and Tailwind CSS. Configure Supabase as the database client with the `pgvector` extension enabled. Define Prisma or Drizzle schema models for `repositories`, `code_nodes` (storing file paths, AST symbols, and vector embeddings), `pull_requests` (storing diffs and review comments), and `technical_designs`. Implement better-auth with email/password authentication restricted to your personal user account. Ensure clean separation between database connection logic and frontend UI components.02Repository Ingestion & Vector Embedding Pipeline
Build an ingestion script that clones local repositories, parses code files into semantic chunks, generates embeddings, and stores them in Supabase.
Build a TypeScript service inside the Next.js app that accepts a GitHub repository URL, clones or reads the file tree, and chunks code files by functions and classes using basic AST heuristics or regex-based parsing. Integrate the Anthropic embeddings API or OpenAI embeddings API to generate vector embeddings for each code chunk. Insert these chunks along with their file paths, function signatures, and vector embeddings into the `code_nodes` table in Supabase. Include an API route to trigger this indexing process manually.03Model Context Protocol (MCP) Server Implementation
Develop a lightweight Model Context Protocol (MCP) server that exposes the indexed codebase knowledge graph to AI coding assistants like Cursor and Claude Code.
Create a Model Context Protocol (MCP) server module in TypeScript that can run locally or be queried via HTTP. Implement MCP tools `search_codebase` and `get_service_topology` that query the Supabase vector database for relevant code chunks and dependency relationships based on natural language queries from AI coding agents. Test the server connection locally to verify that tools return structured markdown context suitable for injection into Claude Code or Cursor.04AI Architect: Technical Design & Scoping Engine
Build the AI Architect planning engine that analyzes requirements and generates technical design documents grounded in the knowledge graph.
Implement the AI Architect planning module. Create a backend service that takes a feature specification or issue description, queries the Supabase knowledge graph for relevant existing code patterns, and prompts Claude Sonnet to generate a structured output containing: (1) Feasibility analysis, (2) Technical design document, (3) Impact assessment across files, and (4) Scope breakdown into work items. Build a UI page in Next.js to display these generated designs and allow iterative refinement via prompt inputs.05GitHub Webhook & AI Code Review Agent
Set up a GitHub webhook endpoint to listen for pull request events, fetch the git diff, run an AI code review, and post comments directly back to GitHub.
Create a GitHub webhook ingestion endpoint in Next.js that handles `pull_request` events (specifically `opened` and `synchronize`). When a PR event fires, fetch the full git diff using the GitHub REST API. Pass the diff along with relevant context retrieved from the Supabase knowledge graph to Claude Sonnet with a system prompt instructing it to perform a strict code review checking for bugs, security risks, and regressions. Format the AI review output into markdown and post it as a comment on the GitHub pull request using the GitHub API.06Dashboard UI & Analytics Polish
Build the central dashboard interface for managing indexed repositories, viewing code review analytics, and monitoring system status.
Build a polished admin dashboard in Next.js using Tailwind CSS. Include views for: (1) Connected repositories list with status indicators and manual re-index buttons, (2) Recent AI code reviews with line count statistics and review summaries, (3) Technical design history log, and (4) Usage analytics tracking total indexed files and token consumption. Ensure responsive layouts and clean error states across all dashboard screens.
