Webhook Based Asynchronous Prediction Callbacks

via “webhook-based asynchronous prediction delivery”

Run ML models via API — thousands of models, pay-per-second, custom model deployment via Cog.

Unique: Replicate's webhook implementation includes HMAC signature verification built-in, reducing the need for custom authentication logic. The platform abstracts webhook management from the prediction API, allowing webhooks to be configured per-prediction or globally, enabling flexible event routing.

vs others: More straightforward than AWS SNS/SQS for simple event delivery, but lacks the durability guarantees and retry policies of message queues; better suited for best-effort notifications than critical workflows.
