PostSail is a publishing API and dashboard for apps and teams that post the same video or text to several social accounts. One HTTPS request creates the post. PostSail checks it against each platform's rules, publishes it to every account, retries temporary errors without posting twice, and reports the result for each account.
What works today: X and Bluesky. YouTube Shorts and TikTok open when Google's and TikTok's app reviews finish; LinkedIn is coming soon; Instagram, Facebook and Threads come later. Every workspace also has a sandbox account for testing an integration.
Built for automation:
- dry runs that run every check without publishing;
- idempotency keys and external ids, so a repeated request never creates a second post;
- scheduling up to 30 days ahead;
- video uploads up to 100 MB;
- an OpenAPI 3.1 file.
On X, links are kept out of the main post, where X charges $0.200 instead of $0.015, and can go in a first comment.
Plans: Starter $19/month (10 connected accounts, 1 user) and Pro $49/month (50 accounts, team of up to 10), both with a 7-day free trial. Payments are handled by Paddle.
