# How to Vibe Code Your Own Serene (and Stop Paying for It)

> The Mac focus app for remote teams

- Site: https://sereneapp.com
- Category: Productivity & Focus
- Verdict: **Serious undertaking** (45/100 vibecodeable)
- Estimated effort: 3-4 weeks of part-time development and system-level debugging

## Verdict

Build a web-based subset in a weekend, but the native macOS app blocker is a serious undertaking requiring low-level system scripting.

If you just want a timer and a daily todo list in a browser, an AI coding agent can scaffold it in an afternoon. However, Serene's true core value lies in aggressively locking down your Mac by force-quitting background apps and modifying system files to block websites. Implementing these OS-level hooks without breaking user permissions or crashing system processes requires deep systems programming that AI agents often struggle to get right on the first few tries.

### What you can't replicate

- Serene's established brand and customer base
- Years of edge-case bug fixes around macOS permission prompts for process management

## What it does

Desktop productivity app that combines goal planning, website and app blocking, Pomodoro timers, and focus music to drive deep work sessions.

### Core features

- One Daily Goal macro-planning interface
- Pomodoro-style session timers
- System-level app process detection and termination
- Website blocking via local hosts file modification or proxy
- Ambient focus audio playback
- Daily deep work analytics and distraction logs

## The business

### Pricing

- Annual Plan: $4/mo — Billed annually for full desktop app access

Founded 2018.
Team size: Small studio team.

## The hard parts

- Writing native macOS background scripts to forcefully close or hide distracting apps (Slack, email clients)
- System-wide URL blocking via hosts file manipulation or local proxy requires admin privileges and error handling
- Syncing blocking states reliably between the native app and browser extensions

## How to vibe code Serene

### Prerequisites

- macOS: Required to build and run native macOS system APIs and automation scripts
- Node.js (free): Required for running the Tauri frontend build tools and TypeScript backend scripts
- Cursor (Free tier / $20/mo): AI code editor for iterating on both the web frontend and system integration logic

### Recommended AI tools

- Cursor: Best editor for reviewing multi-file diffs when combining web UI components with native desktop bridge code
- Claude Code: Handles complex multi-file scaffolding and terminal shell script generation for macOS process management

### Stack

- Frontend: React with Tailwind CSS, packaged via Tauri for native macOS deployment
- Backend: Rust (Tauri core commands for system execution)
- Database: SQLite (via Tauri plugin for local data persistence)
- Auth: None (single-user personal local app)
- Payments: None (personal use)
- Other: macOS AppleScript / shell commands for process management, Howler.js for ambient focus sound playback

### Hosting

- Cloudflare (Hosting static documentation or auxiliary landing pages if needed): $0/mo

### Build guide

1. **Scaffold Tauri macOS Desktop Shell** — Initialize a Tauri v2 project using React and TypeScript, configuring window dimensions, titlebar styling, and system tray integration for macOS.

```
Initialize a new Tauri v2 project with React, TypeScript, and Tailwind CSS configured. Set up the window configuration to create a clean, borderless or modern desktop layout suitable for a productivity app. Implement a system tray icon that toggles the main window visibility. Ensure the build pipeline runs locally on macOS without errors, and establish a modular directory structure for components, hooks, and backend rust commands.
```

2. **Build the One Daily Goal and Task Planner UI** — Implement the core macro-planning interface where the user defines their single primary daily objective and breaks it into actionable sub-tasks with local SQLite persistence.

```
Build a React-based productivity dashboard featuring a prominent 'One Daily Goal' input block at the top, followed by a prioritized sub-task checklist. Integrate local SQLite persistence using Tauri plugins so tasks survive app restarts. Implement smooth animations for completing tasks, checking off items, and rolling over unfinished goals to the next day. Ensure keyboard shortcuts allow rapid task entry.
```

3. **Develop Pomodoro Focus Timer and Ambient Audio Engine** — Construct a robust session timer paired with an audio playback module for ambient focus soundscapes.

```
Create a countdown focus timer component supporting custom work intervals and breaks. Integrate HTML5 audio / Howler.js to stream looping ambient focus soundscapes and binaural beats from local or royalty-free online assets. Build play, pause, volume control, and session-state persistence so timers accurately track elapsed focus time even if the app loses focus.
```

4. **Implement macOS App Process Killer & Distraction Shield** — Write Rust backend commands and Node/Shell scripts to detect running distracting applications on macOS and forcefully hide or close them during focus sessions.

```
Write secure Rust backend commands for Tauri that execute macOS shell scripts (using 'osascript' or 'pgrep'/'killall') to detect and terminate pre-selected distracting native desktop applications (like Slack, Mail, or Twitter clients) when a focus session starts. Handle permission requests gracefully, instructing the user on accessibility permissions if required. Implement a strict toggle state that prevents the user from opening those apps while the shield is active.
```

5. **Add Distraction Logging and End-of-Day Analytics** — Build an analytics view that logs interrupted attempts, tracks daily deep work hours, and renders simple productivity statistics.

```
Build an analytics dashboard view within the React app that queries local SQLite tables to calculate total daily deep work hours, completed goals, and logged distraction attempts. Render clean charts or summary cards showing productivity streaks and interruption frequency over the past week. Add an end-of-day review modal that summarizes accomplishments.
```

### Cost vs paying

**Starting costs (one-time):**

- Cursor Pro (1 month): $20
- Total: ~$20 one-time

**Ongoing costs (monthly):**

- Total: $0/mo

- Paying for the SaaS instead: $4/mo
