Mux is a cloud video platform that provides developers with APIs for video encoding, streaming, and real-time performance analytics. Unlike traditional video infrastructure, Mux offers a unified solution with built-in analytics (Mux Data) to optimize viewer quality of experience. The company was founded by the team behind Zencoder and Video.js, the most widely deployed open-source HTML5 video player, and is trusted by leading brands such as Substack, HubSpot, and Vimeo. Mux has raised over $174M from top investors including Coatue, Accel, and Andreessen Horowitz.

Mux has launched a new metric called Playing time by rendition for its Mux Data platform, allowing engineers to track the actual wall-clock time viewers spend on specific video renditions. This feature aims to help streaming teams identify underutilized bitrate rungs and validate the real-world impact of encoding ladder adjustments.
Mux has transitioned to an internal CDN routing system that utilizes independent health probes and pre-calculated availability scores to manage traffic. By shifting from third-party real-user monitoring to this proprietary architecture, the company achieved a p99 selection latency of 9.9ms.
Mux published a customer story about Cutsio using Mux to turn an audio-only tool into a full video platform and make large video libraries searchable.
Mux announced Find Scenes in Mux Robots, which turns video into structured scene data and uses Shots, a new Mux Video primitive.
Mux published a technical post explaining the algorithm behind Shots, the company’s newest video primitive for detecting shot boundaries.
Mux published an article detailing the complexities of implementing multi-DRM for video streaming, covering Widevine, FairPlay, and PlayReady, along with various encryption modes and packaging considerations for DASH and HLS. The article explains how Mux's platform simplifies these challenges through a unified API for developers. It also contrasts DRM with signed tokens, outlining appropriate use cases for each security measure.
Mux Data has launched custom Monitoring dashboards, allowing users to create persistent, multi-metric views with saved filters for active streams. This feature enables streaming professionals to build tailored, near real-time metric views using various visualization types. The functionality is available for Custom Media and Self-service Media plans.
Mux has launched two new endpoints, `/heatmap` and `/hotspots`, for its Data Engagement API. These features provide per-moment viewer engagement insights and identify the most or least-watched video segments. This allows professionals to optimize content and user experience based on granular consumption data.
An article from Mux analyzes the strengths and weaknesses of RTMP, SRT, and WebRTC as live streaming ingest protocols, providing a decision framework for their use. It details how each protocol works and when to select it based on latency, network conditions, and encoder constraints. Mux notes its native support for RTMP and SRT, while indicating WebRTC ingest requires a dedicated infrastructure provider currently.
Mux has rolled out per-environment rate limits and token priority controls for its API requests. This enhancement allows for better isolation of development, staging, and production environments, and enables users to prioritize API calls to prevent background jobs from affecting user-facing operations. Standard X-RateLimit headers have also been added for monitoring.
