Meeting Management — Private-Deployed Platform
A ¥19,800 perpetually licensed, self-hosted meeting platform — 8 modules, any BCP 47 language, 4-channel international payment, AI site builder + Copilot, dual-QR check-in. v0.6.0 in production.
In short
This is a perpetually licensed, self-hosted meeting system from YGG for enterprises, government bodies, universities/hospitals and event agencies. Eight modules — registration, international payment, QR check-in, live streaming, hotel & transport, agenda & news, AI site builder and Copilot — are natively integrated and deployed on the customer's own servers for a one-time ¥19,800 licence. Two things separate it from generic SaaS registration tools billed per event and per registrant: attendee phone numbers, IDs and payment records stay in the customer's own Postgres, and after the buy-out there are no caps on events, registrants or channels.
What the agent takes off people's plates
Core capabilities
Any BCP 47 language
25+ display labels, with Locale as a plain string so any BCP 47 tag can be added · four-layer localization across UI, registration fields, SMS and email · per-meeting subset of enabled languages · AI one-click translation never overwrites human translations. Domestic and overseas guests open the same link and each see their native language.
4-channel international payment
Native WeChat V3 + Alipay + Stripe + PayPal · 8 settlement currencies (CNY/USD/HKD/SGD/JPY/KRW/EUR/GBP) · payment-channel whitelisting per registrant group (VIP tickets PayPal-only, student tickets WeChat-only) · webhook auto-verification and dedupe · combined checkout for hotel sub-orders · cascading refunds.
HMAC-SHA256 dual-QR check-in
The organiser posts one meeting QR at the desk and paid attendees check themselves in by scanning; attendees can also present an order QR for staff to scan — closed loop in both directions. Links are signed server-side with HMAC-SHA256, so a leaked screenshot still cannot be forged. Every scan is written to `meeting_checkins` (order ID + timestamp + device fingerprint) with live arrived/not-arrived counters.
AI site builder + ⌘K Copilot
6 preset themes (default / minimal / corporate / academic / tech / festival) + AI-generated site config + 12-module drag-and-drop + cross-window iframe live preview + desktop/tablet/phone toggle, with meeting-level overrides on top of business defaults. ⌘K opens the Copilot bubble anywhere: scope-aware conversation (global / meeting:<id>), a 50+ tool registry, 6 generative-UI component classes, business-card OCR with field translation, and 5-minute-TTL confirmation on destructive operations.
Attendee Portal — 7-page mobile loop
Login (phone/email dual verification + language switcher) → home → meeting hub (4-state filter + posters) → my orders (6-bucket filter + pay now) → profile → my hotels (aggregated across meetings) → invoices (7 status colours + cancel request), plus an order-level check-in QR. Attendees go from registration to invoice without ever contacting the organiser's support desk.
Live streaming, hotel and transport in one system
Tencent Cloud LSS with RTMP ingest and authenticated HLS playback — multi-track sessions, paid-only viewing, credentials encrypted with AES-256-GCM. Hotels and shuttles are booked in the same flow: multiple room types and departures, main order plus hotel sub-order kept in sync, three-stage semantics (open / read-only / hidden), and a cross-meeting "my hotels" view. No separate streaming platform or accommodation spreadsheet required.
Perpetual license · 100% self-hosted
¥19,800 one-time licence (1 year of support, deployment and training included) · no caps on registrants, events or channels · data resides in your own Postgres · single-command Docker deploy, intranet or internet · GDPR / China Cybersecurity-Classified-Protection / cross-border-data friendly · perpetual right-to-use, independent of the vendor's survival.
Side by side
Generic SaaS registration tools vs the DataWeaver self-hosted meeting platform
| Dimension | Generic SaaS registration tool | DataWeaver self-hosted |
|---|---|---|
| Data residency & compliance | Data sits on the vendor's servers; compliance risk is yours | Data lands in your own Postgres; compliance stays under your control |
| Payment channels | WeChat / Alipay only — overseas attendees are excluded | Four channels — WeChat / Alipay / Stripe / PayPal — settling in 8 currencies |
| Multilingual support | Chinese plus partial English; registration fields untranslated | Any BCP 47 language, fully translated across UI, fields, SMS and email |
| Billing model | Billed per event / registrant / channel, on an ongoing subscription | One-time buy-out with no registrant or event caps |
| Feature coverage | Incomplete — you end up stitching several vendors together | Registration, payment, check-in, streaming and site building natively integrated |
| Vendor shutdown risk | If the vendor shuts down, you lose access to your data | A perpetual right-to-use that does not depend on the vendor surviving |

Numbers and sources
The data layer comprises 31 PostgreSQL tables covering every business entity — registration, orders, payments, check-in, hotels and site configuration.
The API layer exposes 130+ Admin endpoints and 31+ Public endpoints; the admin console is a single-page app with 11 sub-menus.
Registration supports 13 custom field types (text / select / file / signature and more) and an 11-state registration machine with a dual review track.
The AI Copilot registry holds 50+ tools, and the AI site builder ships with 6 preset themes.
Payments run over 4 channels (WeChat V3 / Alipay / Stripe / PayPal) and settle in 8 currencies (CNY/USD/HKD/SGD/JPY/KRW/EUR/GBP).
The attendee-facing Portal is a 7-page mobile loop: login, home, meeting hub, my orders, profile, my hotels and invoices.
Standard delivery is go-live within 30 days of contract signing: days 1–3 environment onboarding, days 4–14 deployment and configuration, days 15–21 UAT, days 22–30 training and production cutover.

Where it fits
When this approach does not apply
- This is a self-hosted delivery, not a turnkey SaaS: the customer supplies the servers or cloud resources, the domain and SSL certificate, merchant accounts for WeChat Pay / Alipay / Stripe / PayPal, and an SMS gateway account. Getting those approved usually takes longer than the deployment itself.
- Two capabilities have external dependencies: live streaming requires a Tencent Cloud LSS subscription with its own traffic charges, and the AI site builder and Copilot require your own model API key (Qwen, OpenAI or similar). Without them the remaining modules still work, but those two features are unavailable.
- The ¥19,800 covers standard features and a standard deployment. Deep customisation (brand colours, logo, bespoke modules) and integration with CRM, HIS or finance systems are not included; they are quoted separately at ¥800 per person-day after an effort estimate.
- If you run only one or two small free events a year, have no cross-border registration or data-compliance requirement and do not want to maintain a server, a pay-per-event SaaS is usually the better deal. Self-hosting pays off when event volume, internationalisation and data ownership all matter at once.
