Iron.io

Iron.io provides hosted serverless infrastructure for background processing and asynchronous messaging. Its flagship products are IronMQ, a high-performance hosted message queue for passing messages and events between processes and systems with support for push queues, subscribers, and long-polling; IronWorker, a container-based, multi-language, work-on-demand platform for running background jobs and scheduled tasks at scale; and IronCache, a hosted key/value store. All services share a single REST/HTTP API authenticated with per-project OAuth tokens obtained from the Iron.io HUD, and a broad set of official client libraries across Go, Ruby, Python, PHP, Java, Node.js, .NET, and Rust.

Iron.io publishes 2 APIs on the APIs.io network. Tagged areas include Company, Infrastructure, Message Queue, Serverless, and Background Jobs.

The Iron.io catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Iron.io’s developer surface includes documentation, getting-started guide, engineering blog, support, pricing, signup flow, CLI, and 20 more developer resources.
