Matterbridge
Matterbridge 是一个多协议聊天桥接器和消息网关，可实时同步不同通信平台之间的消息、媒体和用户身份。它作为一个协议无关的消息总线，将各种聊天协议转换为通用的内部格式，以实现不同服务之间的无缝通信。
该系统的独特之处在于多平台媒体代理，它下载并重新上传文件和附件，以确保跨协议的可访问性。它还利用 Webhook 身份代理在各平台间复制原始发送者的用户名和头像，通过可自定义的映射和格式化保持身份清晰度。
该网关通过聊天流量中间件提供广泛的流量管理，允许使用正则表达式和可脚本化逻辑进行消息转换、过滤和路由。它支持复杂的消息生命周期管理，包括编辑、删除和线程化对话的同步，同时为第三方服务提供程序化协议集成。
该桥接器可以作为后台服务或在容器内部署，并支持环境变量配置和安全管理 API。
Features
- Messaging Gateways - Functions as a messaging gateway that synchronizes messages, media, and identities across disparate communication platforms.
- Protocol-Agnostic Message Routing - Translates disparate chat protocols into a common internal format to enable seamless message routing between services.
- Cross-Protocol Attachment Handling - Handles file uploads by converting private links to public ones or re-uploading files natively across platforms.
- Cross-Platform Media Bridging - Downloads and re-uploads images, video, audio, and documents between platforms that handle media differently.
- Chat Media Transfers - Transfers files and attachments between different chat services to ensure content reaches all bridged users.
- Scriptable Message Logic - Executes custom Tengo scripts for every message to dynamically modify content and control routing.
- Media Asset Managers - Manages the downloading and uploading of media assets, including format conversion for stickers and images.
- Multi-Platform Gateways - Links accounts and channels across different chat protocols to enable unified communication within isolated gateways.
- Custom Protocol Integration - Provides programmatic interfaces to develop and connect new third-party chat platforms to the bridge.
- Isolated Bridge Gateways - Organizes connected channels into isolated gateways to prevent cross-talk and manage independent conversation streams.
- Multi-Protocol Chat Bridges - Synchronizes chat messages, media, and user identities across disparate communication platforms in real time.
- Cross-Platform Chat Bridges - Synchronizes messages, media, and user identities across different communication platforms to enable unified conversations.
- Cross-Platform Message Relaying - Synchronizes chat messages in real time between different communication platforms to keep conversations consistent.
- Media Synchronization - Provides synchronization of images and file attachments across different chat protocols to ensure cross-platform accessibility.
- Message Content Transformation - Modifies message content and metadata using regular expressions and custom scripts before routing to target platforms.
- Chat Traffic Middleware - Provides a system for transforming, filtering, and routing chat messages using regular expressions and custom scripts.
- Message Routing - Synchronizes and directs chat messages between different protocols using predefined account and channel mapping rules.
- Asynchronous Media Proxying - Implements asynchronous downloading and re-uploading of media files to ensure compatibility across different chat protocols.
- Route Mapping Configurations - Directs message flow by linking accounts and channels across different platforms using structured configuration maps.
- Event-Driven Architectures - Uses an event-driven architecture to decouple connection handlers, ensuring system resilience if individual bridges fail.
- Identity Mimicry via Webhooks - Replicates original sender usernames and avatars by injecting messages through service-specific webhook interfaces.
- Edit and Deletion Synchronization - Propagates message edits and deletions across bridged platforms to keep conversation histories synchronized.
- Programmatic - Executes custom scripts on incoming and outgoing messages to programmatically modify text and sender identity.
- Regex Message Filters - Blocks or replaces specific messages and usernames using regular expression patterns before they reach target platforms.
- Message Lifecycle Management - Provides comprehensive end-to-end state management for the sending, receiving, and updating of chat messages.
- Message Threading - Preserves and synchronizes threaded conversations between platforms that support nested message structures.
- Private Group Synchronization - Synchronizes restricted or private chat groups across compatible platforms to maintain privacy and membership access.
- Protocol Extension Interfaces - Exposes a REST API enabling the integration of third-party chat services not natively supported.
- Multi-Account Protocol Support - Supports simultaneous connections to multiple servers or bots of the same messaging protocol.
- Resilience Mechanisms - Maintains system uptime by allowing the gateway to function even if some bridge connections fail during startup.
- General Platform Authentications - Secures connections to messaging platforms using bearer tokens, service-specific passwords, and certificate verification.
- Cross-Protocol Identity Mapping - Maps usernames and avatars to ensure users are recognizable across different messaging protocols.
- User Identity Customization - Customizes the appearance of users from external platforms using templates to include usernames and protocol origins.
- Channel State Synchronization - Relays user join/leave events and topic changes between messaging platforms in real time.
- Communication Bridges - Multi-protocol bridge connecting IRC to various chat platforms.
- Media & Communication - Bridge between various chat protocols.
