The ability to create AI agents without upfront costs has become a reality, thanks to platforms offering free tools with powerful features. Latenode, for instance, provides 1,000 monthly credits and advanced integrations, enabling businesses to automate workflows effectively. Meanwhile, Rasa Open Source offers unlimited usage but requires technical expertise. Whether you're a small business or a developer, these platforms cater to diverse needs, from testing ideas to deploying full-scale solutions. Here's what you should know about the top free AI agent builders.
Latenode stands out among free AI agent builders by offering a generous free tier with 1,000 monthly credits and unlimited workflow executions. This makes it an excellent choice for small businesses looking to create and operate multiple AI agents without upfront costs. The free plan is designed to support real-world applications, enabling teams to test their AI agent ideas and achieve meaningful automation before committing to a paid plan.
The free tier includes unlimited workflow executions up to a cap of 1,000 monthly credits, along with access to 3 active workflows and 3 connected accounts. This setup is ideal for small-scale operations, as simple tasks consume just a few credits. For instance, a customer support AI agent that uses 2–3 credits per interaction could handle hundreds of support tickets each month entirely free of charge.
On top of these generous limits, Latenode integrates advanced AI models, opening the door to deeper customization.
Latenode’s free plan includes access to advanced AI nodes, allowing seamless integration with popular large language models like OpenAI’s GPT series and Claude. Users can also incorporate other leading AI APIs. With built-in JavaScript support, it’s easy to add custom logic, such as decision trees, response parsing, or business rules, without upgrading to a paid plan. The integration process is straightforward: authenticate your AI service account and drag the relevant AI nodes into your workflows.
With its robust integration capabilities, Latenode also provides an array of powerful workflow tools.
Users on the free plan gain access to the same visual interface and AI features as paid users, with the only limitation being the 1,000-credit monthly cap. The drag-and-drop builder includes features like conditional logic, branching, loops, and error handling. Additionally, enterprise-grade integrations allow AI agents to connect with CRM platforms, email services, databases, and communication tools. Workflow monitoring tools are also available, helping users refine and optimize their AI agents for better performance.
When free tier limits are reached, Latenode offers seamless upgrade options to support growth. The Start plan, priced at $19/month, increases the credit limit to 5,000 and allows up to 10 active workflows. This upgrade path ensures businesses can scale incrementally without having to rebuild their workflows, making it easier to grow based on actual usage. This approach reduces financial risks and provides a clear path for businesses to expand their AI automation efforts as their needs evolve.
Dialogflow is a platform designed to create conversational AI agents using natural language processing and voice interactions. While it offers a free tier, its usage limits make it more suitable for testing and smaller-scale projects rather than full-scale production deployments.
The free tier of Dialogflow imposes restrictions on the number of monthly text and audio requests. This can limit its usability for larger or production-level applications. Additionally, it provides only basic analytics and caps the number of concurrent sessions. These limitations make it a great option for experimenting with ideas but less practical for handling higher demands. When scaling up becomes necessary, many users find themselves needing to upgrade to a paid plan.
Dialogflow comes equipped with features like sentiment analysis, entity recognition, and intent classification, which help it understand the nuances of human language. The free tier also includes small talk modules and spell-checking capabilities. However, for advanced needs - such as integrating custom AI models or third-party language models - users must switch to the Enterprise Edition. Free-tier users are limited to Google's pre-trained models, though these still integrate smoothly with the platform's intuitive visual flow builder.
Dialogflow's free tier supports native integrations with platforms like Google Assistant, Facebook Messenger, and Slack, making it easier to deploy conversational agents across popular channels. Webhook fulfillment allows these agents to trigger external actions, while rich response formats - such as cards, quick replies, and carousels - improve the quality of interactions. Developers can also use the testing console to simulate conversations in real time, which aids in refining and optimizing their agents.
For those needing to manage higher request volumes or access advanced features, upgrading to Dialogflow CX is essential. The paid version introduces enhanced flow management, A/B testing capabilities, and detailed analytics. However, its pay-per-use pricing model can become costly for high-volume applications, making it important to weigh the benefits of the upgrade against its potential expenses.
Microsoft Power Virtual Agents is a user-friendly platform designed to create chatbots without requiring coding knowledge. It integrates seamlessly with Microsoft services, making it a convenient choice for businesses already using Microsoft's ecosystem. The free tier provides basic chatbot capabilities but comes with usage limitations, making it ideal for smaller projects or initial testing.
The free tier is tailored for those exploring chatbot development or working on small-scale projects. While it allows users to build and test conversational workflows, scaling up for more complex or high-traffic applications would require moving to a paid plan.
This platform taps into Microsoft's advanced AI services to power its natural language processing. It supports essential features like recognizing user intents and extracting relevant entities. However, more advanced tools and capabilities are reserved for premium subscriptions.
Microsoft Power Virtual Agents includes an easy-to-use drag-and-drop flow designer, simplifying the process of building conversational paths. Additionally, it integrates smoothly with Microsoft applications, enabling deployment across multiple channels with minimal effort.
For users looking to expand their chatbot's capabilities, upgrading to a paid plan unlocks higher usage thresholds, enhanced analytics, and access to more integrations. These features are essential for businesses requiring more sophisticated or large-scale chatbot solutions.
This overview of the free tier highlights its strengths and limitations, providing a foundation for comparing it with other chatbot solutions like Rasa Open Source.
Rasa Open Source is a free AI agent builder that offers developers unparalleled flexibility and control over conversational AI projects. As a fully open-source framework, it eliminates licensing costs and avoids vendor lock-in, making it an appealing choice for those who want to customize, extend, and deploy their solutions without restrictions. Unlike cloud-based platforms, Rasa provides complete autonomy over your deployment and data.
Rasa Open Source operates under the Apache 2.0 license, which means there are no fees or usage limits. You can build as many conversational agents as needed, process unlimited conversations, and deploy across multiple servers without incurring any costs. This makes it especially appealing to organizations with tight budgets or those prioritizing data sovereignty.
However, using Rasa does require managing your own infrastructure, handling dependencies, and configuring deployments. While this setup demands technical expertise, it offers unmatched scalability and access to all features without additional expenses. For those willing to invest in the technical setup, Rasa provides a cost-free solution that supports expansive development.
Rasa includes built-in natural language understanding (NLU) models for tasks like intent classification and entity extraction. Additionally, it allows integration with external language models through custom setups. Pre-trained models for dialogue management are included, and they work offline, ensuring reliability even without constant internet access.

Rasa excels in managing complex conversation flows through its visual story format and rule-based system. Developers can design multi-turn dialogues, handle context switching, and implement fallback strategies using domain configuration files. Features like slot filling, form handling, and Python-based custom actions allow for deep customization and integration of business logic.
One standout feature is Rasa's interactive learning tool, which enables developers to fine-tune their agents by reviewing and correcting conversations in real time. This creates a feedback loop where the agent improves with each interaction, eliminating the need for costly annotation services or external training data. These workflow management tools make Rasa a strong foundation for building scalable, high-performing conversational agents.
While the open-source version of Rasa provides all core features for free, organizations can choose to enhance their systems with Rasa Pro. This premium offering includes advanced tools like analytics dashboards, conversation testing, and enhanced deployment options. However, many businesses successfully operate production systems using only the free version, provided they have the technical resources to support it.
The upgrade path focuses on streamlining operations rather than adding essential features, ensuring that the time spent learning Rasa's framework continues to deliver value. Whether or not you opt for premium support, Rasa Open Source remains a powerful, cost-effective choice for conversational AI development.
Choosing the right platform for building AI agents requires a clear understanding of each option's strengths and limitations. These factors can shape your development experience and influence how well the platform supports your long-term goals, including scalability and cost-efficiency.
