PostBot: Open-Source Multi-Platform Content Sync Tool

What is PostBot?

PostBot is an open‑source, browser‑native tool that turns your web browser into a single‑stop shop for publishing to dozens of social‑media and content distribution platforms. Whether you’re an individual blogger, a marketing team, or a developer wanting to integrate publishing into a workflow, PostBot gives you:

• One‑click multi‑platform publishing – create content once and push it simultaneously to WeChat, Weibo, X, TikTok, LinkedIn, Bilibili, and many others.
• Local credential handling – PostBot uses the browser’s existing login state, so your username, password, and OAuth tokens never leave your machine.
• Support for multiple media types – text, Markdown, HTML, images, videos, audio, and even custom card‑style posts.
• Smart content adaptation – automatic truncation, slug generation, and platform‑specific metadata (e.g., image aspect ratio, character limits).

The project is maintained on GitHub (https://github.com/gitcoffee‑os/postbot) and follows the Apache‑2.0 license with a few small additions for community safety.

Why PostBot? The Pain Points it Solves

1. Fragmented workflows – Traditional tools force you to copy‑paste each post into separate apps or use multiple browser tabs. PostBot reduces context‑switching with a unified interface.
2. Security concerns – Cloud‑based publishers often require you to upload credentials or API keys to third‑party servers. PostBot keeps everything on your local machine.
3. Limited platform coverage – Many free tools support only Western platforms. PostBot covers major Chinese media outlets (WeChat, Weibo, XiaoHongShu, Bilibili) and expands to international sites easily via plugins.
4. Lack of extensibility – PostBot offers a plugin SDK and public API so developers can add new integrations or customize existing ones.

Getting Started

1. Install the Browser Extension

PostBot is distributed as a browser extension for Chrome, Edge, and Chromium‑based browsers.

1. Visit the GitHub releases page: https://github.com/gitcoffee-os/postbot/releases
2. Download the latest .crx file.
3. Drag‑drop the file into your browser’s extensions page (chrome://extensions/).
4. Enable Developer mode and click Load unpacked if you prefer working from source.

2. Add Platforms

When you first open the PostBot panel, a small floating button will appear. Click it to open the configuration panel:

1. Login – The extension will detect any existing login session in the current tab. If not, simply log into the target platform in a new tab and return.
2. Add a new platform – Click Add Platform, then choose from the drop‑down list. PostBot supports over 20 platforms by default; you can also add custom ones via the API.

Tip: For platforms that require OAuth, simply follow the on‑screen prompts; PostBot will store the token locally.

3. Create a Post

1. In any content editor (a blog post, a Facebook comment, a tweet, etc.), click the PostBot floating button.
2. Select the platforms you want to publish to from the multi‑select dropdown.
3. Input the title, body, and attachments. PostBot automatically formats text as Markdown or plain text, depending on the platform.
4. Click Publish – the extension will call each platform’s API sequentially and report success or failure.

4. Advanced Features

• Smart Reader – For web pages, PostBot’s built‑in article extractor pulls the headline, summary, and main image for you.
• Scheduling – PostBot can push posts on a schedule by integrating with cron or a simple JS timer.
• Plugins – Developers can load custom plugins from the marketplace or build their own via the SDK. Example plugins include a Chinese‑to‑English auto‑translating layer or a plagiarism checker.

Use Cases

Contributing

PostBot’s open‑source community thrives on contributions:

1. Fork the repository on GitHub.

4. Join the discussion on the repo’s issues page or the dedicated WeChat group linked in the README.
