Anlyon Relay is a message queue API designed for serverless teams seeking reliable background job processing without managing traditional infrastructure. The platform enables users to publish a single HTTP request, after which Anlyon Relay manages delivery, retries with exponential backoff, scheduling, fan-out, and dead-letter queues. This approach eliminates the need for Redis, dedicated worker runtimes, or cron daemons, reducing operational overhead for teams deploying on serverless platforms.
The service supports integration with environments such as Vercel, Cloudflare Workers, AWS Lambda, Netlify, Railway, and Deno Deploy. Users can interact with Anlyon Relay through official SDKs for TypeScript and Python, or via its REST API for other languages capable of making HTTP requests. Message publishing is streamlined to a single HTTP call, specifying parameters like URL, body, optional delay, and retry policy. Upon acceptance, Relay returns a message ID, with operations typically completing in under 40 milliseconds.
Anlyon Relay handles delivery attempts automatically, applying exponential backoff with configurable limits. If a message exhausts its retry attempts, it is moved to a dead-letter queue, which retains the full request and response history for debugging and replay. The platform also supports recurring cron schedules and one-off delayed sends, with timezone awareness, allowing users to specify cron expressions and have Relay compute and execute the next run. For more complex automation, Anlyon Relay offers durable multi-step workflows where steps can be chained, paused, or triggered by events, with per-step persistence ensuring that failed steps can be retried independently without re-executing completed ones.
The tool provides real-time visibility into message delivery, including a live event feed, full-text search, and traceable delivery attempts. Users can inspect payloads and monitor the status of messages directly through the dashboard. Anlyon Relay offers a free tier with up to 10,000 messages per month and does not require a credit card to get started. 99% SLA is available on the Pro plan, supporting teams that need high reliability for their background job processing.
In the Messaging, queues & streaming space, anlyon-relay takes a focused approach. Enabling developers to schedule and deliver messages reliably and programmatically via a type-safe Python SDK. It is built as an open-source project for python developers. anlyon-relay is open source under the MIT license. It runs on the web, the command line, and API, and it can be self-hosted.
It is developed by Anlyon, and the product first shipped in 2026. Key capabilities include type-safe scheduling, async support, and message queue integration. It exposes integrations via a public API.
