The verdict: can you vibe code TimeHero?
Build a personal subset for your own schedule or keep paying, because writing a reliable auto-scheduling constraint solver that syncs bidirectionally with calendars requires non-trivial algorithmic work.
While an AI coding agent can scaffold the Next.js frontend, database schemas, and standard CRUD boilerplate quickly, TimeHero's core value rests entirely on its scheduling engine. Replicating an adaptive interval solver that continuously recalculates task start dates around shifting calendar meetings without breaking requires significant algorithmic logic. Furthermore, managing bi-directional webhook sync with Google and Microsoft Outlook calendars introduces brutal state-sync edge cases.
Estimated effort: 6-8 weeks of focused engineering

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js project with Tailwind CSS, configure Drizzle ORM with Neon Postgres, and define core relational schemas for users, tasks, projects, and calendar events.
Scramble a new Next.js project using TypeScript and Tailwind CSS. Install Drizzle ORM and configure connection pooling for Neon Postgres. Create database schemas in `db/schema.ts` for users, projects, tasks (with fields for duration_minutes, due_date, start_date, priority, status, and assigned_user_id), calendar_events (with external_id, start_time, end_time, and user_id), and task_dependencies. Write a migration script and verify database connectivity.02Authentication & User Management
Integrate better-auth for credential and OAuth sign-in, tying user sessions directly to the Neon database.
Install and configure `better-auth` in the Next.js application using Drizzle adapter to persist users and sessions in Neon Postgres. Implement sign-in, sign-up, and session-provider hooks. Create protected routes for the main dashboard layout and ensure user context flows cleanly through server actions.03Calendar OAuth & Bi-Directional Sync
Implement Google OAuth scopes for Google Calendar API, store encrypted refresh tokens, and build an ingestion service for external calendar events.
Implement Google OAuth login specifically requesting calendar read/write scopes (`https://www.googleapis.com/auth/calendar.readonly`). Store OAuth tokens securely in a dedicated user_tokens table. Build a background cron job using Next.js route handlers that fetches upcoming calendar events for authenticated users every hour, upserting them into the `calendar_events` table so the scheduling engine knows when users are busy.04Adaptive Interval Scheduling Engine
Develop the core algorithmic constraint solver that computes optimal task 'do' dates around calendar events and deadlines.
Write a robust TypeScript scheduling algorithm module in `lib/scheduler.ts`. The algorithm must take a user's uncompleted tasks (each with duration and due date), their existing calendar events (meetings where busy = true), and working hours (e.g., 9 AM to 5 PM, Monday-Friday). It must compute contiguous free time blocks and assign tasks into those slots without overlapping meetings. When a new meeting or task is added, the engine must recalculate subsequent task slots. Write unit tests covering edge cases like packed calendars and tight deadlines.05Task Inbox & Kanban / Timeline UI
Build the interactive dashboard views for managing tasks, viewing auto-scheduled slots, and tracking project workflows.
Build a responsive dashboard UI using Tailwind CSS and shadcn/ui components. Include an Inbox view for quick task capture, a project list view, and a timeline/calendar view that visualizes both calendar meetings and auto-scheduled task blocks side-by-side. Implement drag-and-drop or manual overrides for task rescheduling that trigger the scheduling engine recalculation via server actions.06Recurring Tasks & Workflow Templates
Implement smart recurring tasks and reusable project workflow templates with dependency linking.
Implement smart recurring task logic: allow users to set tasks that repeat within a flexible timeframe (e.g. once a week between Monday and Friday) where the scheduler automatically places the next iteration upon completion. Build a workflow template builder allowing users to save sets of dependent tasks as reusable templates that instantly instantiate full project timelines when triggered.07Time Tracking, Polish & Deployment
Add built-in timers, timesheets, error monitoring, and deploy the application to Vercel.
Add a global active timer component that logs elapsed time against tasks into a `time_logs` table and updates automated timesheet aggregates. Configure Sentry for error tracking. Write the final deployment configuration and verify that all environment variables for database connection and Google OAuth are properly set up on Vercel.
