The verdict: can you vibe code Litmaps?
Build a personal-use subset with Next.js, Turso, and an open academic dataset API, but expect significant debugging around force-directed graph performance and citation traversal.
Replicating Litmaps for personal research is a rewarding side project if you scope it down to importing a few seed papers and visualizing their immediate citation neighborhood via OpenAlex. The primary hurdles are handling the sheer volume of academic metadata without expensive enterprise databases and keeping the browser canvas buttery smooth when rendering complex citation graphs. While you won't match their proprietary indexing of 270M papers instantly, plugging into OpenAlex or Semantic Scholar APIs gives you a functioning engine in a few weekends.
Estimated effort: 3-4 weeks part-time
What you can't replicate
- Proprietary aggregated user behavioral data and custom graph ranking weights
- The combined user base and brand footprint following the ResearchRabbit acquisition
- Direct institutional licensing integrations

Build guide
01Project Scaffolding and Database Setup
Initialize the Next.js application with TypeScript and Tailwind CSS, configure better-auth, and set up Turso database schema for users, maps, and saved papers.
Create a new Next.js 16 app with TypeScript, Tailwind CSS, and App Router. Set up better-auth with email/password authentication backed by a Turso SQLite database. Create database tables for users, maps (id, title, userId, createdAt), map_papers (mapId, paperId, positionX, positionY), and user_bookmarks. Include proper migration scripts and environment variable validation.02Academic API Integration Service
Build a robust wrapper service around the OpenAlex or Semantic Scholar API to search papers, fetch metadata, and extract incoming/outgoing citation edges.
Create a TypeScript service layer in `lib/academic.ts` that interacts with the OpenAlex API. Implement functions to search papers by keywords (returning title, abstract, publication year, citation count, DOI, and open access status) and fetch inbound/outbound citation lists for a given paper ID. Add robust error handling, rate-limiting protection, and caching using local memory or Turso.03Seed Mapping and Graph Traversal Logic
Implement the backend logic that accepts seed paper IDs, queries their citation networks, and computes network proximity scores for recommendations.
Implement server actions or API routes in Next.js for seed mapping. When a user inputs seed paper IDs, query the academic API to fetch first-degree and second-degree citation connections. Calculate a basic proximity score based on shared citations and co-references, and format the output nodes and edges for network visualization. Save the generated map state to the Turso database.04Interactive Citation Graph Visualization
Build the core interactive 2D canvas/SVG graph interface mapping papers across time and citation metrics using D3.js or React Flow.
Build an interactive citation graph component using D3.js force simulation or React Flow. The graph should plot papers with X-axis as publication year and Y-axis as citation count or network centrality. Nodes should be clickable to view paper details in a side drawer, support zooming and panning, and visually distinguish seed papers from recommended papers with clear connection edges.05Library Management, Zotero Sync, and Exports
Add bookmark management, BibTeX export functionality, and a basic Zotero collection import option.
Add library management views where users can organize saved papers into custom folders, export selected papers as BibTeX or RIS citation files, and implement a mock/real OAuth sync endpoint to import collections from a Zotero account via the Zotero Web API.06Automated Email Alerts and Polish
Set up a cron job or scheduled task using Resend to send periodic literature summary alerts for user maps matching new publications.
Configure a Vercel Cron route that runs weekly, checks user maps for newly published papers added to the academic index matching their seed topics, and uses Resend to send an automated digest email summarizing new relevant research. Polish the UI with toast notifications, loading skeletons, and dark mode support.

Vibe code Litmaps: FAQ
- Can you vibe code Litmaps yourself?
- Solid side project — 62/100 vibecodeable. Build a personal-use subset with Next.js, Turso, and an open academic dataset API, but expect significant debugging around force-directed graph performance and citation traversal.
- How long does it take to vibe code Litmaps?
- 3-4 weeks part-time — roughly 25-35 hours of hands-on time with an AI coding agent.
- How do you build your own Litmaps?
- Scoped to personal use: Next.js with React and Tailwind CSS, utilizing D3.js or React Flow for citation graph rendering on the front, Next.js API routes handling graph traversal and third-party API orchestration behind it, Turso (SQLite at the edge) for user maps and saved paper bookmarks for data. Follow the 6-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Litmaps without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 3-4 weeks part-time. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Litmaps instead of paying?
- About ~$32 one-time to start and $0/mo to run, versus $10/mo for Litmaps. Break-even: Free build (purely for learning and personal workflow customization).
- What stack should you use to vibe code Litmaps?
- Next.js with React and Tailwind CSS, utilizing D3.js or React Flow for citation graph rendering; Next.js API routes handling graph traversal and third-party API orchestration; Turso (SQLite at the edge) for user maps and saved paper bookmarks; plus Vercel AI SDK, Resend for email alerts.
