When you're building a smart lock brand or choosing a lock platform for a property management deployment, the platform choice matters as much as the hardware. Tuya and TTLock are common OEM routes. This comparison covers app workflow, connection interfaces, white-label options, data privacy, ownership and support scope.
Platform Overview
Tuya is a broad IoT cloud platform covering many device categories. Smart locks are one category among many; review the selected model, account ownership and published connection interfaces before committing to a route.
TTLock is a dedicated smart lock cloud platform developed by Sciener Technology (Beijing). It is lock-specific — every feature in the platform exists for one purpose: managing door locks. It is the dominant B2B lock management platform in the Chinese market and has significant adoption in European and US property management.
Feature-by-Feature Comparison
| Feature | Tuya | TTLock |
|---|---|---|
| App (consumer-facing) | Tuya Smart / Smart Life — polished, widely installed | TTLock — functional but less polished |
| White-label app (OEM) | Full white label via Tuya Industry App SDK | Limited white label via TTLock OEM program |
| API quality (REST) | OpenAPI 3.0 — documented scope | REST API — scope varies by route |
| Lock-specific API depth | Standard (PIN, e-key, access log) | Deep (time-bound credentials, event webhook, card-type control) |
| Property-system connection | Review named interface and event scope | Review lock workflow and current connection scope |
| Smart home ecosystem | Alexa, Google Home, Apple Home, SmartThings natively | Limited (no native Matter) |
| Additional ecosystem requirements | Confirm current model and roadmap | Confirm current model and roadmap |
| Private cloud / on-premise | Confirm current enterprise scope | Confirm current enterprise scope |
| Data storage location | Global servers (US, EU, China selectable) | China servers (GDPR risk for EU) |
| GDPR compliance path | EU server region available; DPA signable | Complex — no EU data residency option |
| OEM hardware ecosystem | Broad device range — confirm selected models | Lock-focused ecosystem |
When to Choose Tuya
- You are building a consumer or prosumer smart lock brand where a named smart-home connection matters to your buyers
- You need a white-label app under your brand for iOS and Android
- Your target market includes smart home installers who already work with the selected Tuya device route
- You need a defined future ecosystem path; confirm the current model roadmap in writing
- You need GDPR-compliant EU data residency — Tuya's EU server region is available with DPA
- You want the lock to connect with video intercom, sensors or other smart-home devices; name each target and review the path
When to Choose TTLock
- You are deploying for managed property or access control where detailed access reports, time-bound credentials and lock-specific API controls matter more than smart-home ecosystem
- Your buyers are facilities managers who care about access logs, reports and defined workflows
- You need card type management (controlling which RFID technology each door accepts) at a granular level
- You are serving Chinese market or markets where TTLock brand recognition is established (TTLock has strong brand recognition among property managers in China and Southeast Asia)
- Your deployment does NOT involve EU personal data — if it does, TTLock's China-only data storage creates GDPR complications
Data Privacy: The Critical B2B Consideration
For EU-market deployments, TTLock's data storage situation is a significant problem. TTLock stores all access log data on servers in China. Under GDPR, this is a third-country transfer that requires Standard Contractual Clauses (SCCs) — and the practical enforceability of SCCs with Chinese companies has been questioned by EU data protection authorities following the Schrems II ruling.
Tuya may offer regional hosting options, but the actual server region, data roles and DPA must be confirmed for the selected account and model. Document the data path before deploying in EU residential or commercial buildings.
The Third Option: Custom Backend
For OEM partners with the required volume and technical team, neither Tuya nor TTLock is the only option. Trudian locks can be reviewed for a custom backend using the selected BLE or Wi-Fi path. This gives you:
- Full IP ownership of the platform
- On-premise deployment (fully GDPR-controlled)
- A separately scoped hosting and account model
- Custom feature development without waiting for platform roadmap
The trade-off is a separate development, security, hosting and maintenance scope. Request a project-specific assessment before choosing this route.
Frequently Asked Questions: Tuya vs TTLock for OEM Smart Locks
Tuya is a broad IoT platform covering many device categories with a wide device range and white-label app options. TTLock is purpose-built for smart locks, with lock-specific features such as time-bound credentials, offline PIN management and access schedules. Compare the required workflow, account ownership, data path and selected lock model before choosing a platform.
Neither platform is automatically GDPR-compliant. Review the actual server region, data roles, retention, transfer mechanism and DPA for the selected account and lock model. For EU deployments, document the data path and obtain legal or privacy advice before committing to either platform.
Both platforms may offer white-label app options, but the available branding, store-account, cloud and support scope must be confirmed in the current OEM terms. Rebranding the app does not transfer ownership of the underlying cloud service. If you need a separately controlled backend, request a project-specific technical and commercial review.
TTLock may be the better fit where time-bound credentials, offline PINs and lock-specific access workflows are central. Tuya may be better when a broader smart-home device ecosystem or white-label application route is the priority. Confirm the current API, account ownership, event scope and selected lock model before committing to either platform.
This is a genuine platform dependency risk. If the cloud platform shuts down or discontinues your product tier, cloud-dependent features — remote unlock, app-based key management, audit log sync — cease to function. Offline features (PIN codes, RFID cards, Bluetooth proximity unlock) continue to work as they do not require cloud connectivity. To mitigate this risk: ensure your OEM contract includes source code escrow for firmware, verify the lock supports offline credential methods as primary fallback, and avoid deploying locks where cloud connectivity is the only access method.
Tuya and TTLock are separate cloud environments. A mixed deployment should be planned around separate administration or a named property-system connection that is reviewed for both models. Confirm event scope, account ownership, data path and acceptance tests; do not assume a shared dashboard.
Tuya, TTLock and a custom backend each have different licensing, hosting, support and development terms. Fees and limits change by account, region, model and volume, so request the current written terms for the selected route. Compare ownership, data path, offline fallback, support and lifecycle obligations alongside the commercial scope.
