Crossposter launches local-first multi-platform publishing dashboard

Crossposter simplifies multi-platform syndication by keeping credentials and draft history entirely local. While this architecture provides excellent privacy, the tool relies on a mix of official APIs and fragile session scraping that will likely require frequent maintenance as platforms update.

• –Keep credentials, drafts, and configuration stored locally in poster.config.local.json rather than on a third-party server.
• –Connect with services ranging from X and LinkedIn to developer hubs like Dev.to and Hacker News.
• –Validate character and media limits for each selected platform before posting to prevent silent submission failures.
• –Include local utilities for image compression, video transcoding, and aspect-ratio cropping.
• –Unofficial integrations using local cookie sessions can trigger security checks or account restrictions.
