What people buildwith Siar.

Publish text, images, video and carousels to 15 social networks with one REST request. Per-network payloads, validation up front, and the network's own error when something fails.

Schedule posts to 15 social networks with a UTC timestamp. Siar publishes on time, never twice, retries failures and tells you through a webhook.

Run social publishing for many customers from one organization: a team per customer, isolated accounts and posts, and pricing that does not scale with the number of accounts.

Read post and account metrics from 15 networks through one API, with a normalised shape and the raw network payload kept alongside.

Publish comments and replies, import the comments people leave on your posts and moderate them through one API, on the networks that expose comments.

Subscribe to 16 signed event types: posts, comments, accounts, X credit and conversations. HMAC-SHA256 signatures, retries with backoff, a delivery log and resend.

A hosted connect page for 15 networks: send a link, the user signs in with the network, and the account lands in their team. Branded with your logo and name.

An MCP server, a JSON-first CLI and a typed SDK for AI agents that post, schedule and read analytics across 15 networks, generated from the same contract as the API.
