The verdict: can you vibe code Missinglettr?
You can build a functional personal clone of the drip campaign and scheduling engine, but maintaining multiple brittle social media API integrations is a continuous maintenance headache.
Replicating the core loop—ingesting an RSS feed, parsing it with Claude, generating a multi-month queue of posts, and displaying them on a calendar—is entirely achievable as a solid side project. However, production social APIs (Meta, LinkedIn, X) require constant maintenance, token refreshes, and app verification hurdles that will consume far more time than building the database schema. If you only want a personal scheduler, building it is a great learning exercise; if you just need content distribution, paying the $15/mo Solo subscription is vastly more rational.

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js project with Tailwind CSS, shadcn/ui, Turso, and better-auth.
Scaffold a new Next.js 16 application using App Router, TypeScript, and Tailwind CSS. Integrate better-auth with email/password authentication configured for a single personal user. Set up a Turso (libSQL) database connection with Drizzle ORM containing tables for: users, content_sources (url, type, last_synced_at), campaigns (title, original_url, content_summary, status), and scheduled_posts (campaign_id, platform, content, scheduled_for, status). Ensure clean folder structure and robust error handling.02RSS Ingestion and AI Drip Extraction Engine
Build an RSS parser and an Anthropic-powered extraction pipeline to generate multi-month social campaigns.
Implement a backend utility using Vercel AI SDK and the Anthropic API that accepts a blog RSS feed URL or YouTube channel ID, fetches the latest items, extracts the full article text, and uses Claude to generate a 3-month schedule of 12 distinct social posts across X, LinkedIn, and Facebook. Each post object must include the target platform, post body copy, extracted hashtags, suggested image prompt, and a calculated scheduled timestamp spaced out over weeks. Store these generated posts in the scheduled_posts table with a 'draft' status awaiting user approval.03Unified Social Calendar UI
Build an interactive calendar view to review, filter, and edit scheduled drip campaigns and posts.
Create a responsive social media calendar dashboard page in Next.js. The UI must display a month/week grid view showing scheduled posts across all platforms with distinct platform icons and status badges (draft, approved, published, failed). Include an intuitive sidebar filter by platform and campaign, and build a modal allowing the user to click any scheduled post, edit its text or timestamp, and approve or delete it.04Background Job Queue & Social API Dispatcher
Set up a durable background worker to execute and dispatch approved posts to social channels at their scheduled times.
Integrate Inngest into the Next.js application to handle scheduled background jobs. Create a cron-triggered function that runs every minute, queries the database for approved scheduled_posts where scheduled_for <= NOW() and status == 'approved'. For each post, attempt to publish it via mock API handlers (or real Meta/LinkedIn Graph API endpoints if credentials are provided in user settings). Update the post status to 'published' or 'failed' with error logging, and handle rate-limit backoffs gracefully.05Analytics Dashboard & Polish
Build a central analytics view summarizing post performance, platform distribution, and campaign reach.
Build an analytics dashboard page visualizing personal social marketing metrics. Implement charts (using lightweight libraries like Recharts) showing total posts published per month, engagement breakdown by platform (X vs LinkedIn vs Facebook), and a list of top-performing campaigns ranked by simulated click-through rates. Polish the entire application interface with consistent dark/light styling using Tailwind and shadcn/ui components.
