letmepost.dev: The Unified Social Media Publishing API

Introduction

letmepost.dev is a tool designed to make sharing content on social media much easier for developers. It acts as a central hub that lets users send one message to multiple social networks at the same time. Instead of writing separate code for each platform, developers can use a single request to post to services like X, Bluesky, and Pinterest. The tool is built with an open-source license called Apache 2.0, which means anyone can use it for free or host it on their own servers.

Benefits

The main advantage of letmepost.dev is that it saves time and reduces errors. It handles the complex work of connecting to different social media platforms so developers do not have to. Here are the key benefits:

• One Request for Many Platforms:Users can send a single post to several social networks simultaneously. This eliminates the need to maintain separate integrations for each site.
• Smart Error Checking:Before sending a post, the tool checks if the content fits the rules of each platform. For example, it ensures a message is not too long for Bluesky. If a post fails, the tool gives a clear message about why, saving API credits and preventing silent failures.
• Faster Setup:The tool uses a pre-approved connection method for big platforms like Meta and LinkedIn. This bypasses long approval processes that usually take weeks, allowing developers to start posting much faster.
• No Duplicate Posts:The system includes a safety feature that prevents the same message from being posted twice if a network connection fails and the user tries to resend it.
• AI Friendly:The tool works well with AI agents. It provides special tools that allow AI programs to log in and post content without needing custom code.

Use Cases

letmepost.dev is useful for anyone who needs to manage social media accounts programmatically. Here are some common ways it is used:

• AI Automation:Developers can build AI agents that automatically post updates about software deployments. The tool ensures these agents do not accidentally post the same update multiple times if they encounter a network error.
• Marketing Agencies:Agencies that manage many client accounts can use the tool to avoid expensive monthly fees charged by other services. They can self-host the software on their own servers to keep data private while still using the easy connection methods for platforms like Instagram and LinkedIn.
• Cross-Platform Sharing:Any developer who wants to share a blog post or news update on X, Bluesky, and Pinterest at the exact same moment can use this service to handle the distribution.

Pricing

letmepost.dev uses a freemium pricing model. This means there is a free version available for testing and basic use. For organizations that need more features or higher limits, there is a flat-rate paid option. Developers who prefer to keep their data on their own servers can self-host the software using a Docker image. This version is completely free and has no hidden fees or limited features.

Vibes

The tool has received positive attention from the developer community for its focus on reliability and ease of use. Users appreciate the clear error messages that help them fix issues quickly. The ability to bypass long approval processes for major platforms like Meta is seen as a major advantage over traditional social media APIs. Reviews highlight that the open-source nature of the project builds trust, as developers know they can inspect the code or host it themselves without restrictions.

Additional Information

letmepost.dev was launched in April 2026. It is built using modern technologies like Astro and Vercel. The project supports several major social platforms, with Bluesky, X, and Pinterest currently fully live. Other platforms like Instagram, Facebook, Threads, and LinkedIn are under review and will be added soon. The tool is compatible with popular AI assistants like Claude and Cursor, making it a strong choice for teams using artificial intelligence in their workflows.
