What it does
Cut EV charging testing costs by 90%. Simulate 1000+ virtual charge points with OCPP 1.6, 2.0.1 & OCPI 2.1.1. Cloud-based protocol testing, automated QA, and load testing for CSMS platforms.
Platform OCPP & OCPI simulator for CSMS testing — run virtual chargers, debug protocol traffic, and validate roaming flows. No hardware. Free to start.
Browser-based OCPP and OCPI emulator for CSMS and roaming QA. Spin up virtual charge points, inspect every message in real time, and share replayable logs with your team. A quick view of the browser-based OCPP simulator and OCPI testing workspace your team uses to validate EV charging software against a CPMS. Simulate the EV charger profiles your team actually deploys. Vendor-style profiles with realistic connector layouts, current types, supported kWh, and OCPP behavior for CPMS testing. The workspace tests OCPP 1.6 / 2.0.1 / 2.1 and OCPI 2.1.1 / 2.2.1 / 2.3.0. EEBUS and Modbus are adjacent energy and industrial standards, not product modules.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
