toolJul 31, 2024, 5:11 AMmultipostter - Effortless Multi-Posting ToolI created a multi-posting tool called "multipostter." To seamlessly share posts across different networks like Misskey, Twitter, and Bluesky, I adopted a pull-type multi-posting method. This approach detects posts from the primary network and mirrors them to other networks, reducing effort while enabling post sharing. Specifically, I set Misskey.io as the primary network and Bluesky and old Twitter as mirror targets. Considering the constraints of each SNS, I defined a universal posting format and utilized AWS Lambda and DynamoDB to achieve a serverless configuration. If you're interested, please refer to the source code on Github.
