The verdict: can you vibe code Less Annoying CRM?
Build a personal single-user subset in 2 weekends, but keep paying if you rely on frictionless multi-provider email/calendar sync.
The core CRUD logic—contacts, notes, custom fields, and task lists—is a standard full-stack web application that an AI coding agent can scaffold rapidly. The real friction surfaces with OAuth token management and webhook processing for Google and Microsoft email/calendar integrations, which break frequently when upstream APIs change. For personal use, building a local-first version with manual notes and task lists is straightforward; maintaining robust background sync across multiple mail providers turns a weekend build into an ongoing maintenance chore.
Estimated effort: 2-3 weekends of part-time development

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js application with Tailwind CSS, shadcn/ui, Turso, and better-auth, establishing core relational tables for contacts, companies, notes, tasks, and pipelines.
Scaffold a new Next.js project using App Router, TypeScript, Tailwind CSS, and configure shadcn/ui. Set up Turso client connectivity using libSQL and configure better-auth with email/password authentication for single-user personal access. Create a comprehensive relational database schema with tables for users, contacts (with fields for name, email, phone, company_id), companies, interaction_notes (linked to contacts with timestamps), tasks (with due dates, completion status, and contact linkage), and sales_pipelines (with stages and deal cards). Ensure proper foreign key constraints, indexes on frequently queried foreign keys, and migration scripts.02Contact & Company Management UI
Build the core contact directory, detail view with interaction timelines, and company grouping interface.
Create a responsive dashboard layout in Next.js featuring a searchable, filterable data table for contacts and companies. Implement detailed contact profile pages that display complete interaction history, including automatically timestamped notes, associated tasks, and company details. Add full CRUD server actions for creating, editing, and deleting contacts and companies. Ensure forms support custom fields stored flexibly as JSON or dynamic columns, and include a CSV data export action that formats and downloads all user contact records.03Task Management & Morning Summary Engine
Implement task tracking linked directly to contact records alongside a background cron routine to generate morning summary emails.
Build a task management module integrated into contact profiles and a centralized daily task list view. Create server actions to mark tasks complete, reschedule due dates, and attach follow-ups to specific leads. Implement a Vercel Cron job that executes every morning, queries tasks due on the current day for each user, compiles them into a markdown list, and dispatches an automated summary email using the Resend API. Handle error logging and retry logic for failed email deliveries.04Sales Pipelines & Custom Fields
Build customizable sales pipeline boards and dynamic field management to track deals across stages.
Develop a drag-and-drop or column-based pipeline view for tracking sales deals across customizable stages (e.g., Lead, Qualified, Proposal, Won, Lost). Implement pipeline management settings allowing users to create custom pipeline boards, add custom stages, and define custom data fields for contacts and deals. Write robust server actions for updating deal stages and persisting custom field key-value pairs in Turso.05Google & Outlook Calendar/Email OAuth Sync
Integrate Google and Microsoft Graph OAuth flows to ingest calendar events and log email correspondence directly into contact timelines.
Implement Google OAuth and Microsoft Graph OAuth authentication flows allowing users to connect their Google and Outlook accounts. Build background webhook endpoints and polling scripts that fetch upcoming calendar events and recent sent/received emails, automatically matching sender/recipient addresses to contact records in Turso. Display synced calendar meetings and email threads chronologically inside each contact's interaction timeline. Handle token refreshes securely and manage API rate limits gracefully.06Polish, Error Handling & Deployment
Add comprehensive error boundaries, loading skeletons, responsive mobile views, and deploy the application to Vercel.
Review the entire Next.js application for error resilience, adding loading skeletons for async data fetches, toast notifications for successful actions, and robust form validation using Zod. Ensure mobile responsiveness across all dashboard views. Configure production environment variables for Turso, better-auth, Resend, and Google/Microsoft OAuth credentials, and prepare the project for seamless deployment on Vercel.
