Local RTMP Server
Local RTMP Server is a lightweight macOS utility that runs an RTMP (Real-Time Messaging Protocol) streaming server on the user's machine, typically on localhost. It allows content creators, streamers and developers to test streaming workflows locally without uploading to a remote service — for example, streaming video from OBS (Open Broadcaster Software) to a local RTMP endpoint for testing, debugging, or recording before going live. The app provides a GUI interface to start and stop the server and typically displays connection information and logs. It is commonly used by live streamers during setup, by software developers testing broadcast pipelines, and by educators demonstrating streaming concepts.
AI Recommendation
1 suggestionLocal RTMP Server is distributed via GitHub as an open-source project by the original developer, and the last visible update was in 2020. The search results do not show evidence of an active native Apple Silicon build being maintained or released. Given that the app was last updated around six years ago and no clear sign of ongoing native support exists, the project appears to be in a minimally maintained or dormant state. The Intel-only build will continue to run under Rosetta 2 for now, but Apple is removing Rosetta 2 in macOS 28 (September 2028), at which point this app will stop launching entirely. If you rely on Local RTMP Server for streaming tests or development, consider reaching out to the original developer (check the GitHub repository) to ask about native Apple Silicon support. Alternatively, evaluate SRS (Simple RTMP Server), an actively maintained open-source RTMP server with documented native macOS support that can be installed via Homebrew and run from the command line — it offers broader protocol support (WebRTC, HLS, SRT, MPEG-DASH) but lacks a GUI. Docker is another option if you are comfortable containerising the RTMP service.
