A portable Agent Skills package for Proxylity UDP Gateway is now on GitHub. Use it with GitHub Copilot, Claude Code, Cursor, Gemini CLI, and dozens of other AI coding tools to design, deploy, and troubleshoot UDP Gateway solutions on AWS.

Send UDP packets to connected clients at any time — no inbound request required. Packet Sources are now generally available to all AWS Marketplace subscribers, with full WireGuard support and all formatters.

WireGuard Listeners can now accept connections from any client without pre-registration — like HTTPS for public services. Lambda destinations can now be invoked asynchronously to trigger durable workflows without the Gateway waiting for a reply.

How avoiding a traditional MQTT/Kafka/Kubernetes IoT stack with serverless UDP yields simpler firmware, longer battery life, and near-zero backend costs — demonstrated with two ESP32 platforms.

We open sourced raptor, a native CLI that sends small files to S3 faster and with 10x less CPU time than the AWS CLI/API by using RaptorQ forward error correction over UDP with WireGuard encryption — no HTTPS, no slow-start, no TLS overhead.

Set Formatter: coap on any destination and UDP Gateway automatically decodes binary CoAP packets into structured JSON — no glue code, no binary wrangling, just serverless CoAP.

We're looking for feedback and design partners on server-initiated delivery to connected clients without waiting for an inbound packet.

Everyone knows WireGuard as a VPN. Fewer know it as a stateless cryptographic protocol you can use as a drop-in encryption layer for any UDP workload — no VPN, no PKI, and none of TCP's head-of-line blocking, connection resets, or lossy-link penalties.

WireGuard Listeners now support Decapsulated Delivery, forwarding only the inner UDP payload to Destinations — enabling shared Destinations, simpler integrations, and advanced routing without custom code.

Few people Google bloom filters. Many Google oil filters. A look at the things developers build that most people will never think about — and why that's our gig.

How to add a minimal NTP server to a Lambda Destination handling WireGuard-encapsulated traffic, enabling embedded devices like ESP32 to sync time through Proxylity UDP Gateway.

One year of building Proxylity and moving beyond traditional virtual machine constraints.

A little story about reliability, idempotency, and why UDP can be the right choice for customer friendly APIs.

Proxylity UDP Gateway now supports AWS Lambda response streaming, enabling functions to send reply packets to remote clients progressively throughout execution.

Proxylity UDP Gateway now supports Amazon Kinesis Data Streams with dynamic partition key extraction, enabling real-time processing of UDP traffic at scale.

BREX (Binary Range Expression) enables dynamic AWS service integrations without intermediaries, simplifying architectures and accelerating innovation cycles for UDP Gateway destinations.

How to leverage CloudWatch Metrics and Logs for comprehensive observability in Proxylity UDP Gateway, from traffic monitoring to error diagnosis.

Proxylity UDP Gateway now supports Amazon SQS FIFO queues with dynamic message group IDs and deduplication, plus new message formatting options for Standard queues.

Proxylity UDP Gateway now supports AWS Lambda's new tenant isolation mode, enabling strict tenant isolation for multi-tenant SaaS applications processing UDP traffic.

IoT Core Data destinations are now available in Proxylity UDP Gateway, enabling seamless integration of UDP-based device protocols with AWS IoT Core's MQTT infrastructure.

How API Gateway destinations enable UDP-to-HTTP integration, unlocking cross-cloud capabilities like calling GCP Cloud Functions, Azure Functions, and external webhooks from UDP traffic. Discover new architectural possibilities for multi-cloud and hybrid integration.

How Proxylity prioritizes Infrastructure as Code (IaC) to enhance developer experience, streamline deployments, and ensure consistency across environments. Discover the benefits of an IaC-first approach in modern cloud infrastructure management.

Exploring the concept of UDP as a "convertible" protocol that can adapt to various networking needs through minimal encapsulation. Learn how this flexibility allows UDP to serve diverse applications effectively.

How Proxylity's UDP Gateway enables syslog services that are reliable, scalable, and free from the traditional server management headaches. Discover how to implement a syslog solution that adapts to your needs without the usual operational burdens.

How Proxylity's UDP Gateway enables custom DNS services that adapt to your specific needs, providing flexibility and control over your network infrastructure. Building a custom DNS service "in house" may have been a non-starter in the past, but today is easy and approachable.

Clarifying network terminology: what "servers," "services," "endpoints," and "serverless" actually mean in practice -- and how understanding the distinctions leads to better architecture decisions when building modern network applications.

UDP is a niche protocol. And for those that need it innovation is stifled by the lack of support for major cloud providers. This article explores the reasons why UDP is often overlooked and how Proxylity is changing that.

Bringing serverless innovation to UDP and beyond -- making complex network protocols as accessible as modern web services. Turn "impossible" ideas into afternoon projects and watch what happens when we remove the cost, risk, and time barriers to network innovation.
