Hi CHT community, I wanted to share something I have been building and see if it is useful to anyone here. TriageOS is a free, open-source progressive web app that gives community health workers structured WHO IMCI triage protocols with zero installation and zero connectivity required at point of care. CHWs open a URL once, it installs as a PWA, and from that point it runs fully offline on any Android or iOS device. It is not a replacement for the CHT. It is designed for contexts where programs want structured clinical decision support but do not yet have the infrastructure for a full CHT deployment, or as a lightweight complement to an existing stack. On the technical side: all clinical data is encrypted on-device with AES-256-GCM before storage, records are chained with SHA-256 hashes for tamper evidence, and the sync layer exports to OpenMRS via FHIR R4. It runs as a bilingual PWA (English and Greek right now) and supports offline background sync when connectivity returns. Demo link: [https://triageosglobal.netlify.app/](https://triageosglobal.netlify.app/) GitHub (MIT): [GitHub - Triageos/triageos: Offline-first WHO IMCI clinical decision support for community health workers in low-resource environments · GitHub](https://github.com/Triageos/triageos) I am specifically looking for pilot partners in CHW programs operating in low-connectivity environments, any scale. If you are running a program and think this could be useful to test, or if you are a CHT implementer who wants to explore whether TriageOS could serve as an entry-point tool before a full CHT rollout, I would love to hear from you. Happy to answer technical questions here or in a call. Amrin ---

Hi @Amrin - thanks for the post. I see this is your first post on the forum - welcome! A new comer to the world of offline first CHT apps is most welcome. While the TriageOS [demo site](https://triageosglobal.netlify.app/) seems functional, the GitHub repo has [no code yet](https://github.com/Triageos/triageos) (though happy to see a very liberal MIT license in there!). Is there a plan to share the code? As well, it would be great to see some documentation on how to set up and configure the app. I think it’s important [we cite the readme](https://github.com/Triageos/triageos#triageos) which does a good job of calling out where TriageOS is in its development lifecycle: > **Important:** TriageOS is currently a Draft v0.1 unvalidated research prototype. It is not clinically validated and must not be used as a substitute for professional clinical judgment or real-world patient diagnostics. Finally, given TriageOS syncs upstream with [OpemMRS](https://openmrs.org/), I would be sure to post [on their forums](https://talk.openmrs.org/) as well (I didn’t see any search results for `TriageOS` just now). Best of luck!
