Postier
Social media management platform — create, schedule, and publish from one place.
Role
Full-stack development of the platform: content generation, visual calendar, multi-platform scheduling, and analytics.
Architecture
NuxtJS, NodeJS — SSR platform with AI content generation, visual calendar, bulk scheduling, and RSS feeds.
Results
Production SaaS with transparent pricing, multi-platform support (Bluesky, LinkedIn, Mastodon, X), and made-in-France development.
Context
Postier is a social media management platform that combines content generation, smart scheduling, and analytics. The product targets creators, teams, and agencies managing multiple social accounts who want to centralize their workflow without juggling between tools.
The main challenge was building a platform flexible enough to handle content creation, adaptation, and scheduling across multiple platforms (Bluesky, Discord, Dribbble, LinkedIn, Mastodon, Slack, X) while remaining simple to use.
Goals and Constraints
- Centralize content creation, scheduling, and publishing across all social networks
- Provide an AI-powered content generator based on niche (hooks, captions, hashtags)
- Automatically adapt a single piece of content to each platform's format
- Offer a visual calendar for planning and previewing scheduled posts
- Support bulk upload via CSV and RSS feeds for evergreen content recycling
- Maintain transparent and accessible pricing
Solution and Architecture
The platform is built with NuxtJS for server-side rendering and performance, with a NodeJS backend handling multi-platform scheduling and social API integrations.
The 3-step workflow — brainstorm, create, schedule — guides users from idea to publication. The content engine generates hook, caption, and hashtag suggestions based on the user's niche, then the adaptation system transforms a single piece of content into platform-specific posts.
The visual calendar provides an overview of the schedule with drag-and-drop, while the bulk upload and RSS feed features enable automated content recycling.
