Overview
Post+ is a comprehensive social media management platform that lets content creators publish to 6 major platforms simultaneously. With LinkedIn, YouTube Shorts, Facebook, Instagram, X/Twitter, and TikTok integrations, creators save hours of manual posting while maintaining platform-specific optimization and perfect mobile previews.
The Challenge
Content creators were drowning in repetitive work, manually posting the same content across multiple platforms with inconsistent formatting and constant authentication headaches. Existing tools forced expensive per-platform pricing and required manual reconnections when tokens expired. Creators needed an affordable, unified solution that just works.
Our Solution
We built a full-stack SaaS platform with smart automation at its core. The Multi-Platform Publisher handles 6 platforms with a single interface, automatic thread creation for X, and platform-specific character validation. Our OAuth Management system uses PKCE-secured flows with automatic 30-minute token refresh, handling each platform's unique requirements (Google non-rotating, LinkedIn 60-day rotation, TikTok 24-hour rotation). The Credit System offers two plans: Free (10 posts per platform on 5 platforms) and Créateur (€9.99/month for 50 posts per platform across all 6). Mobile Previews show pixel-perfect iPhone frames with platform-specific UI for TikTok, Instagram, YouTube Shorts, and X. Stripe Integration manages billing seamlessly, while Edge Functions power all platform connections and publishing workflows.
The Results
Post+ is now live and serving content creators across Europe. We've achieved operational integrations with all 6 platforms, automatic token refresh that eliminates manual reconnections, and €9.99/month pricing that's 80% cheaper than competitors. The Créateur plan offers 300 posts per month versus competitors' 50-100 post limits. As a registered PostPlus SASU company (SIREN 993 858 646), we're fully GDPR-compliant with complete French legal documentation. The platform handles all OAuth complexity, rate limits, and API versioning automatically—creators just focus on creating great content.
