GreatWait - 2026 Pricing, Features, Reviews & Alternatives

GreatWait is a cloud-based scheduling API that enables developers and AI agents to dispatch HTTP calls to their own services or authorized third-party APIs at a future time, on a delay, on a recurring interval, or via cron expression with full time zone support. Every outgoing request is cryptographically signed over exact bytes with a timestamp and occurrence ID, automatically retried on failure with exponential backoff up to five attempts, and logged with status, timing, and up to 10 KiB of the server response per attempt. Signing keys can be rotated without downtime, and secret header values are encrypted and never exposed after entry.

GreatWait is accessible via REST API, JavaScript SDK, command-line tool, and a web dashboard, targeting software development teams, SaaS application backends, and AI agent tooling workflows. A 24-hour forecast of upcoming occurrences supports autoscaling decisions. The platform exposes a remote MCP (Model Context Protocol) server, allowing AI coding agents such as Claude Code, Codex, and Cursor to create, read, and cancel schedules in natural language without custom integration wiring. Documentation is published in llms.txt, SKILL.md, and OpenAPI formats for agent-readable consumption.

GreatWait eliminates the infrastructure overhead of maintaining a pending-jobs table, polling worker, or cron server. Pricing is pay-per-use at $1 per 100,000 attempts, with retries included and no charge accrued while schedules are in a waiting state. Failed or missed calls are fully visible and diagnosable through attempt logs, and receiving servers can verify request authenticity and reject replays using the built-in signing mechanism.
