A Go bot framework with stateful commands, rich lifecycle management, and customizable components for chat service integration.
Sarah is a Go-based bot framework that enables developers to build customizable bots for chat services like Slack, Gitter, XMPP, and LINE. It solves the problem of creating interactive, state-aware bots by providing features such as stateful commands for conversational flows and robust lifecycle management for reliability.
Go developers building chatbots for multiple platforms, especially those needing advanced features like conversational context, live configuration updates, and customizable components.

Enables bots to maintain conversational context for multi-step interactions, allowing features like guided forms or games, as shown in the guess example with user-specific state tracking.
Fine-grained, replaceable components let developers customize every aspect, from adapters to storage, reducing complexity for adapter developers who only need to focus on chat service protocols.
Supports dynamic configuration changes without restarting the bot, improving uptime and flexibility in production, as detailed in the wiki for seamless operation adjustments.
Panic-proofed concurrent execution and customizable alerting mechanisms ensure reliability, with components designed to handle failures gracefully and notify administrators of critical events.
The modular architecture requires understanding multiple interfaces and lifecycles, which can be overwhelming for new users, as evidenced by the extensive wiki and example code needed for setup.
Only provides adapters for four chat services; integrating with others like Discord or Telegram requires implementing the Adapter interface from scratch, adding development overhead.
Major version updates (v2, v3, v4) have introduced breaking interface changes, as noted in the IMPORTANT NOTICE, potentially disrupting existing projects and requiring migration efforts.
