Social Batcher

Batch post to Bluesky, Threads, Mastodon, Substack, and LinkedIn from a single tab. No servers, no tracking.

Stop juggling tabs. Start batching. Social Batcher is the lightweight, privacy-focused extension that lets you write one post and schedule it across your favorite platforms instantly. Designed for creators, developers, and privacy advocates who want powerful scheduling without handing their data over to a third-party server. 🚀 SUPPORTED PLATFORMS Bluesky (Direct API) Threads (Official Meta API) Mastodon (Any Instance) Substack (Notes & Posts) LinkedIn (Pro Feature) ✨ KEY FEATURES Smart Compose: Write in the "Master" box and sync text to all platforms instantly. Platform Overrides: Want to add hashtags for Mastodon but keep it clean for Threads? Customize the text for each platform individually before sending. Smart Counters: Character limits adjust dynamically (500 for Threads, 3000 for LinkedIn, etc.) so you never get cut off. Local Scheduling: Schedule posts to run automatically in the background. Privacy First: Your tokens and drafts are stored locally on your device. We do not have a server. We cannot see your posts. 🔥 PRO FEATURES (Unlockable) Support development to unlock power-user tools: LinkedIn Support: Post to your professional network. First Comment Automator: Automatically post a "Link in comments" reply immediately after your main post goes live. Bulk CSV Import: Schedule a month of content in one click via spreadsheet. "Share Tab" Button: Instantly draft a post with the link and title of your current active tab. 🔒 PRIVACY & PERMISSIONS Social Batcher is a local-only application. Storage: Your drafts and API keys are saved in your browser's local storage. Host Permissions: We request access only to the APIs required to publish your posts. Dynamic Access: We now support any Mastodon instance or custom Substack domain by asking for permission only when you add the server. 🆕 PATCH NOTES: Version 1.3 New Features First Comment Automator (Pro): You can now set a "First Comment" (e.g., for external links) that will automatically reply to your own post seconds after it goes live. Select All: Added a global checkbox to toggle all platforms at once. Dynamic Permissions: Improved security model. The extension no longer requests "All URLs" access. It now dynamically requests permission only for your specific Mastodon instance or custom Substack domain. Fixes & Improvements Threads API Update: Updated authentication logic to Graph API v24.0.
