All-in-one time tracking, billing, and budgeting across your tools

The verdict: can you vibe code Everhour?
You can build a standalone personal web dashboard for time tracking and budgeting, but replicating the multi-platform footprint and browser extensions injected into 40+ third-party tools is a massive undertaking.
Everhour is not just a simple timer app; it is an integration-heavy ecosystem spanning a full-stack SaaS web app, a macOS menu bar client, native mobile apps, an Apple Watch extension, and browser content scripts that manipulate foreign DOM trees. While an AI coding agent can scaffold the core Postgres database, Next.js frontend, and basic timer logic quickly, maintaining browser extension injection scripts across changing third-party SaaS apps (Asana, Linear, Jira) introduces endless maintenance drag. Furthermore, managing dated billing rates, complex budgeting alerts, and multi-currency invoices requires rigorous relational database architecture. For personal use, paying for the tool is infinitely more pragmatic unless you restrict your scope strictly to a self-hosted standalone timer.
Estimated effort: 3-5 months of serious development

Build guide
01Database Schema & Core Relational Data Model
Initialize the Supabase PostgreSQL database schema with tables for organizations, users, projects, tasks, time_entries, budgets, and billable rates.
Using Supabase and PostgreSQL, write a comprehensive SQL migration script for a time-tracking and project-billing SaaS. Create tables for: 'organizations', 'users' (with role-based access control: admin, manager, member), 'clients', 'projects' (with fields for budget type: fixed_fee vs non_billable, budget amount, and hourly rate), 'tasks' (linked to projects), and 'time_entries' (tracking user_id, task_id, start_time, end_time, duration_seconds, billable boolean, and dated rate snapshot). Add foreign key constraints, indexes on user_id and project_id for performance, and Row Level Security (RLS) policies ensuring users can only access data within their organization.02Authentication & Workspace Setup
Implement authentication and workspace organization management using better-auth.
Set up better-auth in a Next.js App Router project connected to our Supabase PostgreSQL database. Configure email/password authentication and Google OAuth. Implement multi-tenant workspace logic where a user belongs to an organization and can be invited via email. Create onboarding pages for creating a new workspace or joining an existing one, and protect all dashboard routes behind an auth middleware check.03Time Tracking Dashboard & Manual Entry UI
Build the core time tracking web interface supporting both running timers and manual time logs.
Build a full-featured time tracking dashboard in Next.js using Tailwind CSS and Shadcn UI. Create a top bar with a live active timer component that persists state across page reloads using local storage and server sync. Add a weekly timesheet matrix view grouped by project and task, showing days of the week (Mon-Sun) with input fields for logging hours. Include a modal for creating manual time entries with date, project selector, task selector, billable toggle, and notes.04Project Budgeting, Cost Tracking & Alert Engine
Implement project budget management and an automated alert system checking consumption thresholds.
Create a project budgeting and financial calculation module in Next.js. Build a project settings view to define total budget caps (hours or monetary value) and hourly cost vs billing rates. Implement server-side calculation logic to aggregate total tracked time and compute burn percentage. Build a background job or server action check that evaluates projects when time entries are saved, triggering simulated email notifications via Resend when a project hits 75%, 90%, and 100% of its budget.05Reporting & Profitability Analytics
Develop flexible reporting views analyzing billable hours, team utilization, and project profitability margins.
Develop a comprehensive Reports analytics page in Next.js using a data table component and charting libraries. Allow users to filter time entries by date range, team member, client, project, and billable status. Calculate total tracked hours, billable amount, effective hourly rate, and profit margins. Implement functionality to save custom report views and export report data to CSV format.06Invoicing Module from Tracked Time
Build an invoicing generator that converts unbilled billable hours into professional client invoices.
Build an Invoicing module in the Next.js web application. Create an 'Invoices' database table and an interface allowing users to select unbilled billable time entries for a specific client and project range. Automatically aggregate hours and line items into a clean, printable invoice view with customizable tax rates and company details. Include status tracking (draft, sent, paid) and an option to mark invoices as paid.07Browser Extension Scaffolding for Third-Party Injection
Build a companion browser extension using WXT to inject simple timer buttons into target web tools.
Using the WXT (Web Extension Tools) framework, scaffold a browser extension supporting Chrome and Firefox. Implement a content script configured to run on match patterns for a mock task board (or local development testing page). The content script should detect task item headers in the DOM and inject a lightweight 'Start Timer' button next to them. When clicked, authenticate against our main Next.js SaaS backend via API token to start a running timer associated with that task title.
