Show HN: Awsmux – Multi-account AWS CLI, up to 5.4x faster, 7.4x fewer tokens
Awsmux is a new tool designed to execute AWS CLI commands across multiple accounts and regions in parallel. It significantly improves performance and reduces token usage for AI agents interacting with large-scale cloud infrastructure.
Why it matters
It provides a more efficient and cost-effective way for developers and AI agents to manage complex, multi-account cloud environments, reducing latency and operational overhead.
Run one AWS CLI command across your whole fleet in parallel: hundreds of accounts in seconds, safely.
One command fanned out across every account and region at once (100 parallel workers by default, --concurrency raises it), identities verified before anything runs, results merged into one stream. No more shell loops that take a coffee break to crawl the fleet. And anything that mutates is stopped by an approval boundary that even an AI agent with your admin credentials cannot talk its way past. The demo above is a real terminal against the bundled 100-account sandbox fleet; replay it yourself in one command with make build fleet-up .
