Twelvet
Free Apache-2.0 microservices starter pairing Spring Boot 3 with Spring Cloud Alibaba/Tencent and a React + Ant Design admin.
TwelveT is worth a look if your team is already committed to Spring Cloud Alibaba or Spring Cloud Tencent and you want a pre-assembled Spring Boot 3 base with a React + Ant Design admin, RBAC menus/roles/users, a code generator and Seata transactions already wired together. You skip a lot of boilerplate. The realistic caveats come from the project's own material: the documentation site is Chinese-language, the seed data reports no stable v1.0.0, and the AI pieces (RAG, TTS, STT, LLM) are experimental rather than documented features. Compare it against hand-rolling Spring Cloud plus your own React admin (more control, far more work) or a commercial Java microservice starter (support

Skip TwelveT if your team writes no Java or Spring Boot, or if you need English documentation and a stable versioned release before you ship.
Experimental AI features (RAG, TTS, STT, LLM) are advertised but thinly documented, so anything you build on them is your own engineering time.
TwelveT is Apache-2.0 open source, so there is no licence line item at any team size; your cost is developer time. Against a hand-rolled Spring Cloud + React admin build it is cheaper up front but you own the untangling. Against a commercial Java microservice starter you trade a licence and support contract for a framework with no stable v1.0.0 and Chinese-language docs. Fit is small-to-mid Java teams, not organisations that need a vendor SLA.

What is Twelvet?
Twelvet — Free Apache-2.0 microservices starter pairing Spring Boot 3 with Spring Cloud Alibaba/Tencent and a React + Ant Design admin. Best for Enterprise Java teams building microservices on Alibaba or Tencent cloud, Teams that need a pre-built RBAC admin panel and code generator, Projects needing Seata-based distributed transactions. Free to use.
TwelveT is a free, open-source microservices framework built on Spring Boot 3, Spring Cloud Alibaba, Spring Cloud Tencent and Spring OAuth2, with a React and Ant Design admin frontend. Its homepage describes it as a way to explore microservice development on the most widely used stack pieces, and it ships a built-in permission architecture: menus, roles, users, dictionaries, parameters, code generation, distributed file storage, distributed transactions and aggregated Swagger documentation. The stated rationale is splitting business domains into services you can scale horizontally for availability rather than running one monolith. It is licensed Apache-2.0 (the site footer reads Copyright © 2019-2021 twelvet.cn), so commercial use carries no license fee, and the code is hosted on both GitHub and Gitee. The seed data also flags experimental AI hooks — RAG, TTS, STT and LLM — that are early-stage and lightly documented. This is not a low-code platform: you are expected to be fluent in Java and Spring Boot, and the documentation site at doc.twelvet.cn is written in Chinese.

Behind the verdict
TwelveT's pitch is assembly, not invention. The homepage names the stack plainly — Spring Boot 3, Spring Cloud Alibaba, Spring OAuth2, React, Antd — and the value is that the wiring is already done: service split, Spring OAuth2 authentication, RBAC menus/roles/users, dictionary and parameter management, code generation from database tables, distributed file storage, Seata-based distributed transactions, and aggregated Swagger docs behind one entry point. If you have ever spent the first three weeks of a Java microservices project gluing those pieces together and building an admin UI from scratch, that bundle is the actual product here, and it is Apache-2.0 licensed so the cost is your time, not a licence fee. The stated design goal — split business domains so each service can be developed and scaled independently for availability — is standard microservice reasoning, honestly stated rather than dressed up. The friction is real and you should price it in. Documentation lives on a Chinese-language site, so English-only teams will be reading translated pages or source code when they hit an edge case. The seed data reports no stable v1.0.0 release, which means APIs and module structure can move under you mid-project; treat any adoption as a fork-and-pin decision rather than tracking upstream. The AI features advertised in the seed data (RAG, TTS, STT, LLM) are experimental and thinly documented, so plan around them being demos, not deliverables. Community support skews to Chinese forums, so unusual combinations of Spring Cloud Tencent plus Seata plus your own modules may leave you self-reliant. Where it fits: Chinese-speaking or bilingual Java teams standing up an internal admin-heavy microservice system on Alibaba or Tencent cloud, teams that want a code generator and an Ant Design back office on day one, and developers who want a working reference implementation of Spring Cloud patterns to learn from. Where it does not: teams without Java/Spring Boot depth, anyone shopping for low-code, and organisations that need a vendor SLA, English documentation and a stable versioned release before they will ship to production. One structural note — TwelveT is a framework, not an LLM product, so the usual question about which foundation model it wraps does not apply; it is source code you own and run.
Models under the hood
as of 2026-11-13
Limitations
- Documentation is primarily Chinese, so English-only teams will translate or read source when they hit edge cases.
- The seed data reports no stable v1.0.0, meaning APIs and module structure can shift mid-project — fork and pin rather than tracking upstream.
- The AI integration (RAG, TTS, STT, LLM) is experimental and not documented in depth, so treat it as demo material.
- Community support is small and mainly in Chinese forums, leaving unusual stack combinations self-reliant.
- It assumes Spring Boot and Java fluency and is not a low-code tool.

Where the pricing makes sense
The company stage and team size where Twelvet's pricing actually pencils out — and where peers do it cheaper.
TwelveT is Apache-2.0 open source, so there is no licence line item at any team size; your cost is developer time. Against a hand-rolled Spring Cloud + React admin build it is cheaper up front but you own the untangling. Against a commercial Java microservice starter you trade a licence and support contract for a framework with no stable v1.0.0 and Chinese-language docs. Fit is small-to-mid Java teams, not organisations that need a vendor SLA.
Has Twelvet's pricing changed?
No plan price for Twelvet has moved since we began logging in Aug 2026; the pricing page is re-read on every verification pass.
Who should pick Twelvet?
Pick Twelvet if you are Enterprise Java teams building microservices on Alibaba or Tencent cloud, Teams that need a pre-built RBAC admin panel and code generator, Projects needing Seata-based distributed transactions, Chinese-speaking Spring Boot developers wanting a modern stack starter.
Look elsewhere if you are Non-Java teams or developers without Spring Boot experience, Projects that need a low-code or no-code platform, Teams requiring extensive English-language documentation, Organisations that need a stable versioned release before shipping to production.
Skip it if Skip TwelveT if your team writes no Java or Spring Boot, or if you need English documentation and a stable versioned release before you ship.
GeneratedReal-world workflow fit
Concrete scenarios for the personas Twelvet actually fits — and what changes day-one when you adopt it.
You scaffold a new microservice system: clone TwelveT, split your first two domains into services, and use the built-in RBAC so menus, roles and users exist before your team writes business logic.
Outcome: You reach a logged-in Ant Design admin backed by OAuth2 in the first days instead of spending weeks on authentication and permission plumbing.
You wire order and inventory services through Spring Cloud Alibaba and route the cross-service writes through Seata, then expose both through the aggregated Swagger docs.
Outcome: Distributed transactions and a single API reference page work without you assembling each Spring Cloud component by hand.
You try the experimental RAG or TTS hooks inside a Spring Boot 3 service to see whether they fit your product.
Outcome: You get an honest read on how early those modules are before committing roadmap to them.
Use cases
- Stand up a microservices admin dashboard with RBAC and code generation already built in.
- Deploy a distributed backend where Seata handles cross-service transactions.
- Build an OAuth2-authenticated SaaS backend with an Ant Design admin UI.
- Try experimental RAG or TTS hooks inside an existing Spring Boot 3 project.
- Use it as a working reference to learn Spring Cloud Alibaba and microservice patterns.
Setup time & first value
How long it actually takes to get something useful out of Twelvet — broken out by persona, not the marketing-page minute.
For a Java/Spring Boot developer: clone from GitHub or Gitee and get a running admin shell the same day. First real value (your own domain services plus generated CRUD) is typically a week or two, depending on how much Spring Cloud you already know. Non-Java teams should budget far longer or not start.
Switching to or from Twelvet
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a hand-rolled Spring Cloud monolith split: swap your custom auth and permission code for TwelveT's OAuth2 and RBAC modules, then port services one at a time.
- →From a standalone React admin plus separate Java backend: point the Ant Design frontend at TwelveT's aggregated Swagger-backed APIs and retire the duplicate admin.
- →From another Java microservice starter: re-map your modules onto TwelveT's Spring Cloud Alibaba/Tencent structure and move code-generated CRUD to its generator.
- ↗To a fully hand-rolled Spring Cloud setup: keep your domain services, replace TwelveT's admin and permission modules with your own, and re-implement OAuth2 wiring.
- ↗To a commercial Java microservice platform: export your service boundaries and schema, then rebuild auth, RBAC and code generation on the vendor's stack.
