Defer
Defer was a Paris-based, Y Combinator-backed (W23) zero-infrastructure background jobs platform for Node.js and TypeScript developers, founded in 2022 by Bryan Frimin and Charly Poly. The product converted regular JavaScript/TypeScript async functions into managed background jobs with configurable retries, throttling, concurrency controls, scheduled crons, multi-environment support, alerting, and a hosted dashboard — removing the need for developers to operate their own queues, workers, and Redis-style infrastructure. Defer shipped client SDKs and framework integrations (Next.js, RedwoodJS) and a CLI/build pipeline that uploaded function bundles to the Defer cloud for execution. The company appears to have wound down its hosted service in 2024 — the defer.run domain now 301-redirects to digger.tools, no end-of-service post-mortem is publicly linked from the homepage, and the GitHub organization (github.com/defer-run) last saw meaningful activity in July 2024 with the final defer.client release v2.3.0 cut on 2024-03-06. The open source client libraries remain available but are effectively unmaintained and the hosted backend they depended on is no longer operational. This catalog entry preserves the historical footprint of Defer as part of the 2022-2024 wave of "zero-infrastructure" background-job and durable- execution startups (Inngest, Trigger.dev, Hatchet, Temporal Cloud, Restate) so the design pattern and the players who pursued it remain discoverable in the API Evangelist network.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Defer the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Defer scores 9.2/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Defer
Each block below is one kind of artifact we hold for Defer. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
