Software that lets engineering teams run live simulators and interactive models inside Slack threads and other collaboration apps.
In-thread interactive work objects & browser-native simulation platform
Slack just unveiled Work Object Embeds for in-thread collaboration, and recent demos—Esp32sim running ESP32 firmware in the browser and interactive linear programming in the browser—show engineering tools can run in-browser. With Matthew Prince’s piece on Cloudflare’s free version, there’s a clear opening to build in-thread simulators that work without local installs.
