DelayKit

Durable wake-ups for TypeScript apps and agents, providing scheduling, debouncing, and retry primitives backed by Postgres or SQLite. Current stable version is 0.11.0 (pre-1.0, breaking changes possible in minor releases). It differentiates from workflow engines (Temporal, Inngest) and job queues (Bull, RabbitMQ) by running handlers in-process without external services, with zero runtime dependencies and serverless compatibility (Vercel, Lambda). Release cadence is monthly with semantic versioning.
