Best Alternatives to hi.new in 2025

hi.new is an open-source multiplayer Grok Bot platform that enables your bot to autonomously interact with other bots for scheduling, introductions, and file sharing—all under your access control. If you're exploring similar tools or need a different approach to bot-to-bot communication, here are the best alternatives to hi.new, ranging from open-source frameworks to hosted automation platforms.

Botpress

Botpress is a powerful open-source conversational AI platform that supports multi-bot orchestration and channel integration. While it doesn't focus on bot-to-bot direct messaging like hi.new, it offers a visual flow builder and NLU engine to create complex bot ecosystems that can share context via APIs and webhooks.

Rasa

Rasa is an open-source machine learning framework for building contextual AI assistants. It excels at handling multi-turn conversations and can be extended to enable inter-bot communication through custom actions and external services, making it a flexible alternative for developers who want full control over bot interactions.

Microsoft Bot Framework

This enterprise-grade framework from Microsoft supports building and connecting bots across multiple channels. It includes a Bot Connector service that can route messages between bots, and its open-source SDK allows for custom bot-to-bot protocols, though it requires more setup than hi.new's simple handle-based approach.

BotKit (by Howdy.ai)

BotKit is an open-source toolkit for building bots for Slack, Facebook, and other platforms. It provides a middleware system that can be used to create bot-to-bot message relays, and its simple JavaScript API makes it easy to prototype multiplayer bot interactions without a heavy platform.

Dialogflow (Google Cloud)

Dialogflow is a hosted NLU platform that lets you build conversational agents. While not designed for bot-to-bot chat, you can use its fulfillment webhooks to connect multiple Dialogflow agents, enabling them to exchange intents and data. It's a good choice if you prefer a managed service with built-in Google infrastructure.

Hugging Face Chat UI + Gradio

For AI-focused developers, Hugging Face's open-source Chat UI and Gradio can be combined to create custom bot endpoints. You can deploy multiple bots and use Gradio's API to let them call each other, offering a lightweight, research-friendly alternative that emphasizes model interoperability over a dedicated multiplayer protocol.

Mattermost + Bot Commands

Mattermost is an open-source messaging platform that supports bot accounts. You can create multiple bots that listen to each other's messages in channels or direct messages, effectively enabling bot-to-bot coordination. It's a practical alternative if you already use Mattermost for team collaboration and want to leverage its permissions and audit logs.

hi.new stands out for its simplicity and focus on autonomous bot-to-bot communication with granular access control. However, depending on your needs—whether you require enterprise integration, advanced NLU, or a lightweight DIY approach—alternatives like Botpress, Rasa, or even Mattermost can provide similar or extended capabilities. For most users seeking a drop-in replacement, open-source frameworks like Botpress or Rasa offer the most flexibility, while hosted options like Dialogflow are better for teams that want minimal infrastructure management. Evaluate your technical stack and desired level of control to choose the best fit.
