Everything you need, and more.

We've done the heavy lifting, so you can ship fast, without the maintenance multiplier every platform brings.

Hosted OAuth

Multicast hosts the OAuth flow for you. No dev apps, or platform approvals.

Rate-limit orchestration

We track every platform's limits per account and queue inside them. Platform 429s become our problem, not yours.

Retries & idempotency

Transient platform failures retry with exponential backoff. Idempotency keys make double-posts impossible.

Media pipeline

Upload once. We transcode, resize, and validate to each platform's spec automatically.

Publishing

Create, update, and delete posts across every connected account with one request.

Scheduling

Queue content for any time, any timezone. Change your mind up to the minute it ships.

Webhooks

Delivery confirmations, failures, and engagement events, pushed to your endpoint in one consistent format.

Engagement

Read and reply to comments across platforms through one model

Analytics

Impressions, engagement, and audience metrics, normalized across platforms.
