Docker 运行需同时映射 8080 和 9000 两个端口，UI 在 8080；GPG 提交签名、merge proposals、Vault 等密钥后端属 Pro 功能，需许可证；v2 与 v1 代码分属不同分支，找 v1 需切到 main 分支

flipt server 硬件要求按 README 说明
README 未说明硬件要求，只强调单二进制、默认无数据库等外部依赖，可本地或 Docker 运行
有 Docker 镜像
把功能开关当代码存进你自己的 Git 仓库，用分支和 CI/CD 管理发布
基于 Git 原生的特性开关管理方案，把开关配置纳入版本控制，方便团队在持续交付中安全地灰度发布和回滚。
核心能力
- 功能开关直接存放在自有 Git 仓库，带完整提交历史与 blame
- 环境可映射到 Git 分支、目录或独立仓库，彼此完全隔离
- 用 SSE 流式 API 实时推送开关变更，客户端无需轮询
- 单二进制零外部依赖，默认不需要数据库
- 提供 REST、gRPC 接口并支持 OpenFeature 标准
容易踩的坑

[!NOTE]
Looking for Flipt v1? You can find the v1 code on themainbranch and documentation at docs.flipt.io.
Why Flipt v2?
Finally, feature flags that work with your existing Git workflow.
Flipt v2 is the first truly Git-native feature management platform that treats your feature flags as code. Store your flags in your own Git repositories, use your existing branching strategy, and deploy flags alongside your code using the tools you already know and trust.
🚀 Git-Native by Design
- Own your data: Store feature flags directly in your Git repositories
- Version control: Full history and blame for every flag change
- Branch and merge: Test flag changes in branches before merging to production
- Deploy together: Feature flags deploy with your code using existing CI/CD pipelines
🌍 Multi-Environment with Git Flexibility
- Environment per branch: Map environments to Git branches for seamless workflows
- Environment per directory: Organize flags by microservice or team within a single repo
- Environment per repository: Separate repos for different products or security domains
- Complete isolation: Each environment has its own namespaces, flags, and configurations
⚡ Developer Experience First
- Zero infrastructure: No databases, no external dependencies by default
- GitOps ready: Works with existing Git-based deployment workflows
- Real-time updates: Server-Sent Events (SSE) streaming API for instant flag propagation to client-side SDKs without polling
- Modern UI: Intuitive interface with full Git integration and dark mode support
🔒 Enterprise Security & Control
- Self-hosted: Keep sensitive flag data within your infrastructure
- Secrets management: Secure storage and retrieval of sensitive configuration data (OSS)
- GPG commit signing: Cryptographically sign all flag changes for enhanced security (Pro feature)
- Merge proposals: Code review workflow for flag changes (Pro feature)
- Audit trails: Complete history of who changed what and when
- OIDC/JWT/OAuth: Enterprise authentication methods supported
Flipt v1 vs v2: What's New?
| Feature | Flipt v1 | ✨ Flipt v2 |
|---|---|---|
| Storage | Database-centric (MySQL, PostgreSQL, SQLite) | Git-native with optional SCM sync (GitHub, GitLab, BitBucket, Azure DevOps, Gitea, etc.) |
| Environments | Single namespace model | Multi-environment with Git flexibility |
| Branching | Not supported | Full Git branching with environment branches |
| Data Ownership | Stored in a database (MySQL, PostgreSQL, SQLite) | Stored in your Git repositories alongside your code |
| GitOps | Read-only Git integration | Full read/write Git integration |
| Deployment | Requires database setup | Zero dependencies - single binary |
| Version Control | Basic audit logs | Full Git history and blame |
| Merge Process | Direct flag changes | Merge proposals with code review |
| Real-time Updates | Polling required | Server-Sent Events (SSE) streaming API for instant updates |
| Multi-tenancy | Manual namespace management | Environment-based isolation |
| Secrets Management | None | File-based providers available in OSS, HashiCorp Vault, cloud secrets management (AWS Secrets Manager, GCP Secret Manager, Azure Key Vault) available in Pro |
Use Cases
Perfect for engineering teams that want to:
- Ship faster with confidence: Deploy flags with your code using existing Git workflows
- Enable trunk-based development: Merge incomplete features behind flags without risk
- Implement proper GitOps: Treat infrastructure and feature flags as code
- Maintain security compliance: Keep sensitive flag data within your infrastructure
- Scale with multiple environments: Manage flags across dev, staging, and production seamlessly
- Enable team collaboration: Use familiar Git workflows for flag reviews and approvals
