Slashes agent token costs by 7.4x while parallelizing fleet-wide AWS commands.

Strengths

•Rigorous 150-session benchmark proves 5.4x speedup and massive token savings for agents.
•Built-in approval boundary prevents AI agents from executing destructive commands safely.
•Single Go binary with stdlib only; spins up a 100-account LocalStack sandbox for testing.

Weaknesses

•Niche appeal limited to teams already managing complex multi-account AWS organizations.
•MCP startup race conditions caused 12 session failures in the author's own benchmarks.

Post Description

awsmux fans one AWS CLI command out across hundreds of accounts and regions in parallel and merges the results into a single stream. There's an MCP server built in for agents.

In a 150-session benchmark, agents using awsmux beat agents using the raw AWS CLI in every test: up to 5.4x faster, up to 2.9x cheaper, up to 7.4x fewer tokens.

Single Go binary, stdlib plus cobra only. Feedback welcome.
