Don't just take our word for it. Real feedback from the community.
“Running Kimi K2.6 on my Android phone via Termux with Fusion CLI feels like pure magic.”
“Unified gateway latency is insane. Shifted our entire team off individual API keys to Fusion.”
“Finally an open source agentic development environment that runs standalone without bloat.”
“The ~4MB Rust binary starts instantly inside Termux. I build microservices on the train now.”
