WhatA lightweight client SDK and server middleware that lets API clients generate globally unique resource IDs before creation requests, turning all POST-create operations into idempotent PUTs without custom idempotency key infrastructure.
SignalDevelopers express frustration that POST is inherently non-idempotent and wish they could simply let clients generate IDs and use PUT for creation, but worry about the complexity of globally unique ID generation, collision handling, and convincing teams to adopt the pattern.
Why NowULIDs and UUIDv7 have recently gained broad adoption as time-sortable, collision-resistant IDs that are safe to generate client-side, removing the historical objection that client-generated IDs are unreliable.
MarketAPI developers and platform teams building CRUD services; millions of developers use REST frameworks; no existing library packages this pattern end-to-end with both client generation and server validation.
MoatWeak — this is more of a pattern than a product, easily replicated by any framework, limiting long-term defensibility.
