MeeeetUp FaceID

id.meeeetup.comconsole.meeeetup.com
Face recognition check-in platform for events, offices, hotels, and venues — people register their face once through an invite link, then cameras at entry points recognize them automatically and mark them as arrived, with no tickets, scanning, or app needed. Currently in active development. Sold as a face-ID provider service other products integrate with. Built as a Turborepo monorepo: a Hono + Bun API with layered repository/domain/service architecture, Drizzle ORM + PostgreSQL, a versioned public API with auto-generated OpenAPI docs, Vite + React + TanStack Router consoles, and a distributable cross-platform face-capture SDK (web MediaPipe + React Native ML Kit) that scores faces on-device and uploads only the best frame per person.

Sargalay — AI API Gateway

sargalay.com
AI API gateway for Myanmar developers — one OpenAI-compatible endpoint in front of 400+ models, billed per token with MMQR top-ups from any local banking app (no USD card). Edge-first Hono API with end-to-end typed RPC and shared Zod schemas across a public Next.js site and four Vite dashboards. Spendable credit is derived from the transaction ledger rather than a mutable balance, metered from real upstream token counts, and confirmed on screen over SSE. The same tool-calling assistant answers on the site, in Telegram, in Messenger and behind Discord commands; an MCP endpoint exposes the account to the user's own agent. A second product, Bizsite, turns pasted text and uploaded documents into a published Burmese business site with its own visitor assistant, billed to the owner's gateway credit.
