Expo launches cloud iOS simulators and Android emulators for AI coding agents

Nov 12, 2026
Agents can reproduce a bug, fix it and test it on cloud simulators in parallel, leaving recordings on the pull request, for $0.10 a minute.

Expo, whose tools developers use to build iOS, Android and web apps, has launched Expo Simulators, cloud-hosted iOS simulators and Android emulators for AI coding agents, according to a press release.

Expo argues that verification is now the bottleneck in mobile development: agents write code quickly but often cannot run the app to check it, iOS simulators need Apple hardware, and running several agents means several memory-hungry emulators on one laptop. With the new service, a bug report can go to an agent that reproduces, fixes and tests it on cloud simulators in parallel, leaving a screen recording, screenshots and logs on the pull request. It works with Cursor, Claude Code and Codex, and lets teams run the iOS simulator without a Mac.

Expo Simulators is available now on paid plans at $0.10 per simulator minute, with 60 minutes a month included. "The agent was the fast part," said co-founder and CTO James Ide.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
