GreatWait

GreatWait schedules reliable one-off and recurring HTTPS callbacks for apps and agents. Create a callback through the REST API, dashboard or hosted MCP server. Choose a delay, interval or time-zone-aware cron schedule, with your chosen HTTP method, headers and JSON body. Requests are signed, recoverable failures are retried, and delivery attempts are recorded so you can inspect outcomes and cancel future work. Forecast upcoming scheduled deliveries to inform your own capacity and scaling decisions. Your application runs the business logic; GreatWait handles the waiting and delivery.

Pricing is usage-based: US$1 per 100,000 delivery attempts, with retries counted as attempts. Prepaid credit starts at US$10 and never expires. New accounts receive US$1 of trial credit, valid for 14 days. One project is included; each additional project costs US$5 per month. Prices are before tax.
