What Is AllPub?

Every content creator faces the same headache: write a blog post, then manually reformat and copy-paste it to Medium, Dev.to, Hashnode, your own site, maybe a newsletter. Each platform has its own quirks — headings, code blocks, images, embedding. Doing it by hand is error-prone and time-consuming.

AllPub solves this with a “write once, publish everywhere” workflow. You compose in AllPub using a structured editor, and it handles the formatting translation to each target platform automatically.

The pitch from the HN announcement was straightforward: save hours of manual cross-posting and reach your entire audience across all platforms without the repetitive work.

Setup Workflow

AllPub is a web-based tool — no installation required.

Step 1: Create an Account

Step 2: Compose Your Content

Use the AllPub editor to write your article. The editor supports:

• Rich text with headings, bold, italic, links

• Tables and blockquotes

Step 3: Connect Your Publishing Platforms

Link your accounts for each target platform:

• Medium
• Dev.to

Step 4: Publish with One Click

When your content is ready, select your target platforms and hit Publish. AllPub handles the format conversion for each platform’s specific requirements.

Deeper Analysis

What Makes It Different

Most cross-posting tools either use RSS feeds or require you to paste content into their UI. AllPub takes a more structured approach — content is stored as structured data (not just HTML), and the publishing layer handles platform-specific transformation.

This means if Medium doesn’t support a specific formatting feature, AllPub degrades gracefully rather than mangling your layout.

Supported Platforms

Based on the site and HN discussion, AllPub supports:

• Medium
• Dev.to
• Hashnode
• Ghost
• Substack
• Custom webhook (for headless CMS integration)

Content Deduplication

Platforms like Medium and Dev.to may flag or penalize duplicate content. AllPub generates platform-native content rather than scraping HTML, which helps avoid content-scraping detection from search engines.
