Picking the right AI Agent building platform is like online dating; lots of pretty profiles, most of them leaving you wondering why you wasted your time.

The worst part is that most people pick platforms based on hype rather than functionality. You need to choose the right platform based on your needs and skills.

 

So, let’s dive in and discover the one for you. But before that, let’s decode AI Agents.

What are AI Agents?

The term “Agent” has multiple definitions:

• Classical AI characterizes Agents as systems capable of sensing their surroundings and taking action within those surroundings.
• Some describe Agents as fully autonomous systems that function independently over extended timeframes, leveraging resources such as functions or APIs to engage with their environment and make contextual decisions.
• Other perspectives apply this term to more structured implementations that follow defined operational sequences.

Rather than a rigid definition, it is better to classify these variants as Agentic systems, where LLMs autonomously:

• Focus on workflow completion. They control operations and tool utilization.
• Determine the timing for tool execution to accomplish the main goal and establish methods for task completion.

Which AI Agent builder platform is the best for you?

1. Tars

Tars is a No-Code AI Agent builder platform, making it accessible for everyone to use.

The platform’s main advantage is its accessibility. It has a free plan, and it is not a “free trial for 7 days” or “credit card required” situation. They have over 2,000 pre-built templates for multiple use cases. This makes it easy for users to customize AI Agents to suit their needs.

The pricing is straightforward for both internal teams and customer-facing solutions. The free plan gives you 50 messages per month. The Pro plan for teams starts at $20 per month, while the Premium plan for customer-facing solutions starts at $499 per month.

2. n8n

n8n is a platform best suited for developers.

The setup is simple but not cheap. It starts at €20 per month with no permanent free plan. You get a 7-day trial, and then you have to pay. It comes with a lot of technicalities, which is great if you are building complex workflows and are comfortable with the platform’s technical depth.

This platform is ideal for developers who enjoy complexity and have the skills to take full advantage of it.

3. CrewAI

CrewAI is a multi-Agent platform. Users can either code from scratch or use existing templates along with a No-Code builder. It is enterprise-focused and offers an open-source version that requires technical know-how.

It doesn’t show pricing on its website. Some may view this lack of transparency as a red flag. While you can start a cloud trial, pricing is only visible after you create a free account. Once you’re in, the basic plan starts at $99 per month, while the ultra plan can reach up to $120,000 a year.

4. Relevance AI

Relevance AI targets operations teams specifically. However, Relevance AI doesn’t require you to be a developer to figure out how to build Agentic workflows.

The platform uses a credit-based model. The free plan gives you 100 credits per day, which is quite useful. The pro plan costs $19 per month for 10,000 credits. The catch in the credit system is that you may run out of credits faster than you expect because almost every action consumes them.

This platform, as the website suggests, is best for operations professionals who want to automate repetitive tasks.

5. Gumloop

Gumloop is yet another No-Code Agent Builder that is perfect for people looking to build solutions with ease.

The messaging is simple, but the pricing is not. The free plan includes 1,000 credits. The Starter plan costs $97 per month for 30,000 credits.

This platform suits those who want ease of use and are willing to pay extra for it.

In a nutshell

Pick a platform that helps you automate without overwhelming you, and you’ll be ahead of 90 percent of businesses still doing everything manually.

Don’t overthink it. The one that best fits your technical ability, automation needs, and budget is the right choice. Like most things in life, there is no perfect answer. It depends on your unique requirements.

The productivity gains are real, but only if you choose the right platform and know how to use it effectively.
