He gave Muse access to his staging site to test plugin updates. It tested everything, including edge cases he specified, and replaced an abandoned plugin with new code, saving him two days of work every few weeks.

Renaming his company, he had Muse design a new logo, reskin the website and make all the DNS changes in GoDaddy. He says it went flawlessly and estimates $7,000–10,000 saved (his own estimate).
Alexandru built a multi-agent coding workflow: he first works out a plan with Muse, has Codex review that plan, then uses Muse Spark via OpenCode to implement it, and finally has Codex review it again. Muse can also run his project locally and open a browser for him to click-test. He says it feels like agents nested inside agents, but the dev experience is smooth.
