Convo is a software development kit (SDK) designed to enhance LangGraph agents by providing persistent memory, observability, and resilience without the need for traditional databases. It allows developers to create agents that retain facts, preferences, and goals across sessions, making them stateful and capable of handling multi-user interactions automatically. The SDK emphasizes ease of use, requiring no complex setup or infrastructure, which can streamline development processes significantly. Key features include time-travel debugging, which lets users rewind and restore the agent's state at any moment, and built-in checkpointers for recovering run states. The SDK supports up to 10,000 checkpoint operations per month for free, making it accessible for side projects and prototyping. Paid tiers, starting at $29 per month for startups, offer increased operations, memory, and support options, scaling up to $99 for enterprise-level needs. Convo's advantages over traditional checkpointers are clear. It eliminates the need for extensive boilerplate code and complex database setups, which can often lead to errors and maintenance challenges. Instead, Convo provides a plug-and-play solution that manages memory and threads seamlessly, allowing developers to focus on building better agents rather than troubleshooting infrastructure issues. This positions it as a strong choice for teams looking to advance their AI capabilities without the usual headaches of setup and maintenance.
