Oxylabs Launches MASQUE-Powered Residential Proxies for Real-Time AI and HTTP/3 Data Pipelines
Industry-first native UDP proxying eliminates TCP packet stalls and head-of-line blocking, setting wire-speed transport for large-scale data ingestion.

VILNIUS, Lithuania – 6 October 2026 – Oxylabs, a global web intelligence platform serving biggest AI labs, has announced support for the Multiplexed Application Substrate over QUIC Encryption (MASQUE) protocol across its enterprise proxy infrastructure, becoming the first provider to deliver native HTTP/3 and QUIC proxying over a residential proxy network – a crucial breakthrough for real-time AI development, market intelligence, and digital innovation.
The move sets a new benchmark for data pipeline speed, reliability, and modern protocol compatibility as the wider web continues its transition to HTTP/3.
“As the web transitions to HTTP/3 and agentic AI systems demand continuous, real-time web grounding, legacy TCP proxying is becoming a severe data collection bottleneck. Bringing native MASQUE support to our network ensures enterprise pipelines and AI systems ingest live web data at wire speed without transport stalls,” said Justinas Lapienis, Product Manager at Oxylabs.
For years, enterprise proxy networks have relied on transport mechanisms built around TCP. That worked well enough when most of the web ran on HTTP/1.1 and HTTP/2, but it creates real friction in an HTTP/3 world. Traditional proxies switch a request back to the older HTTP/2-over-TCP style before it reaches the website, adding overhead and inheriting TCP's weaknesses.
When a single packet is lost, TCP holds up every other request traveling over that connection, a problem known as head-of-line blocking, and every new connection pays a repeated handshake cost before any data can flow.
The more of the web that runs on HTTP/3, the more often a proxy has to do this downgrade, so the extra handshakes and the stalls from a single lost packet add up across millions of requests into slower, less reliable data collection.
MASQUE was developed and standardized by the IETF's MASQUE Working Group precisely to close that gap. It is not a single specification but a family of IETF standards for carrying proxied traffic over QUIC and HTTP.
The piece Oxylabs has built into Residential Proxies is CONNECT-UDP, which carries UDP traffic. Instead of forcing a modern connection back through an older TCP tunnel, MASQUE opens a UDP path so a real QUIC/HTTP-3 connection runs all the way to the target.
That passes the benefits of QUIC straight through to data pipelines: independent handling of packet loss so one dropped packet no longer stalls everything behind it, faster connection setup with fewer round trips, and sessions that survive network changes instead of dropping.
It is the same approach already running behind the scenes in Chrome's own IP Protection feature, at a very large scale. Those gains matter most in the industries moving fastest to large-scale data collection.
For teams building AI agent infrastructure, running real-time e-commerce and market intelligence, or supporting cybersecurity work that depends on large-scale data ingestion, the network layer determines whether a pipeline keeps up or falls behind.
A proxy that speaks QUIC end to end lets those teams collect at the pace their work demands, without the transport layer becoming the bottleneck.
Modernizing the transport layer enhances security without changing Oxylabs’ compliance standards. Every connection is authenticated at the gateway with TLS 1.3 encryption before traffic reaches an exit node, backed by the company’s established KYC protocols, 24/7 misuse monitoring, and full adherence to GDPR and CCPA guidelines.
MASQUE support is available on Oxylabs Residential Proxies now. Existing customers do not need new credentials or a different endpoint, and integration documentation and technical developer guides are available to support adoption.
