SocialRelay

Free during early access. No credit card required.

Create once. Publish everywhere.

Manage, review, schedule and publish content across Facebook, Instagram, TikTok, X, and Threads from one workspace — without copying the same post between five apps.

Start Publishing FreeSee How It Works

One workflow. Five platforms.

Each platform has its own rules. SocialRelay enforces them while you write, so you find out a post is too long before you publish it, not after.

Facebook

One image or one video.

  • One image or one video per post
  • Caption and hashtags
  • Publish now or schedule

Instagram

Every post, a Reel.

  • Up to 10 images composited into one Reel
  • Upload an MP4 to publish it as a Reel directly
  • Reorder the images before rendering

TikTok

Photo posts, up to ten.

  • Photo posts with 1–10 images
  • Caption and hashtags
  • Publish now or schedule

X (Twitter)

Text or up to four images.

  • Text-only posts, or 1–4 images
  • 280 characters including hashtags, counted live
  • Overflow highlighted in the preview

Threads

Longer text, bigger carousels.

  • Text-only posts, or up to 20 images
  • 500 characters including hashtags, counted live
  • Carousel publishing

From content to published in minutes.

  1. 01Receive

    Content arrives from your pipeline over MCP, or you create it directly.

  2. 02Review

    See each platform’s version rendered the way it will actually appear.

  3. 03Customise

    Edit captions, reorder carousel images, drop what does not fit.

  4. 04Schedule

    Publish now, or pick a time. Scheduling is timezone-aware.

  5. 05Publish

    A background worker posts to each platform and retries what is worth retrying.

  6. 06Track

    Every attempt is recorded, with the platform’s own error if it fails.

Built for AI workflows.

AI agents and production pipelines can send structured content straight into your review queue over MCP — the same open protocol Claude and ChatGPT use to talk to external tools.

Content arrives automatically. Nothing publishes until it passes validation and someone approves it.

Automation without losing control.

Content can arrive on its own, but publishing stays a decision. Review each platform’s version, edit the caption, reorder the carousel, drop a platform entirely — then publish or schedule when you are ready.
