Nah, I don’t think that’s the case. But, these tools are getting more powerful and I would start paying attention if I were you.

I’m mostly saying this to myself as well because I saw all these AI agent platforms pop up last year and they were basically just automation tools that have existed (with new branding to get investors excited).

So I held off on creating an article like this. I don’t like trend-hopping.

But, now I think there are a few tools that are actually promising. So I went through and tested a bunch over the past two months. And I’m excited to show you all the cool tools I’ve found.

So in this article, I’m going to show you what you need to be aware of when evaluating AI agent builders and then go over some of my favorite ones.

Okay, no more rambling. Let’s get into it.

What is an AI agent platform?

An AI agent platform is software that allows you to create, deploy, and manage autonomous agents. These programs are generally no-code tools that help you automate repetitive tasks in your everyday life.

Today, tech workers mostly use AI agents to help automate routine tasks. Think of it this way: if you can create a list of steps to accomplish a specific task, that you would have given to an associate or intern, AI agents can now do them.

If you can create a step-by-step process for doing something, it can be automated. And that is the ultimate goal of AI agents.

On the plus side, AI agents will help you do a lot more with fewer people. This is great if you’re a solopreneur or freelancer. What you would have given to a virtual assistant can now be done with an AI agent platform — and they don’t need coffee breaks (although who doesn’t love those).

Now that we know what these tools are, let me go over some things you should be aware of when evaluating AI agent companies and how to know if they make sense for you.

What to look for in an AI agent platform

We all know that artificial intelligence is here to stay and grow. Innovation is inevitable. But, with any new technology, there will be opportunists who look for a quick cash grab.

Today, many tools that advertise themselves as “AI agents” aren’t really all that promising — or anything new. But, there are a few new tools in the recent months that have come up and I am so excited about it.

I wanted to write this article a year ago, but I felt it wasn’t a good idea because I don't like deceiving people. But now that these tools have evolved more, and I’m actually being mind-blown by many of them, I’m here to give you a list of AI agents I truly believe in.

But before we dive into that, let’s talk about some things you should be aware of when going through these tools.

Here’s what you consider when signing up for an AI agent builder:

• Integrations with LLMs and APIs: You hands down need to find a builder that can integrate easily with a wide range of LLMs (large language models) and software APIs. ChatGPT, Claude, Gemini, or any other LLM — the AI agent platform needs to integrate with these. At the same time, you need a tool that can integrate with a wide range of software in your tech stack. This way, you can combine your software tools with the AI capabilities brought by LLMs.
• Costs and credits: AI tools can get expensive. This is mainly because they work on a “credit” basis. Each API call to an LLM or software tool costs money. Albeit it’s pennies. But these add up. Make sure you understand the pricing structure. For example, some of these tools require you to integrate with your own OpenAI API, while others eat the cost and have native LLM integrations. Just be aware of this.
• Autonomous task execution: You want to make sure whatever AI agent platform you use has the ability to run complex tasks automatically without you having to get involved. Some of these platforms will allow you to set the frequency at which you want these programs to run. Just be aware of the ones that do and don’t.
• Speed: These tools use a lot of energy. Because they’re bouncing between different API calls, some of them will execute tasks kinda slower than others. Make sure to test out trials of each tool and run some complex workflows to get a feel for how fast (or slow) they are.
• Security: It’s no secret that AI tools, like LLMs, work because they are trained on millions of data points and documents from the past (and present). If you have sensitive data or information that you don’t want to get leaked, make sure the tool you use will not use your information as training data.
• Community & support: Lastly, make sure the platform you use actually cares about your success. What I mean by this is that you want to find a tool that has amazing customer support and resources to help you when you get stuck or confused. If you can find a community of people using the tool on Reddit or Slack, even better.

Okay, now that we know what to look for, let’s go over some of my favorite AI agent platforms and builders.

10 best AI agent platforms your team should be using

Here are my top picks for the best AI agent platforms:

1. Gumloop
2. Relay.app
3. HockeyStack
4. Stack AI
5. Voiceflow
6. OpenAI's Operator
7. Devin AI
8. AirOps
9. Zep
10. Postman

Alright, let’s dive deeper into each of these AI agent builders.

1. Gumloop

• Best for: Marketing teams (SEO, ads, web scraping).
• Pricing: Free plan, then starts at $97 per month.

Number one on our list is Gumloop. Founded in 2023 by two Canadian prodigies, this AI agent platform has quickly become one of my favorite tools in recent months.

At its core, Gumloop is a no-code tool that allows you to automate any workflow in a visual interface. If you’ve used Zapier, or know what it is, Gumloop is like that but with an AI-first approach. I would describe it as if Zapier and ChatGPT had a baby.

Gumloop works through three parts:

• Nodes: These are elements you drag onto a canvas. Think of different software tools and LLMs.
• Flows: These are the connections you make between nodes to create an automated workflow. This is the main value of Gumloop.
• Subflows: These are flows that you can isolate and use as part of a bigger workflow. It’s like a Flow within a Flow. This part blows my mind because I have yet to see another AI agent software do this.

Gumloop also has a wide range of templates you can use to automate different workflows. This is what I think makes it different from some other AI agent builders. Right away, you can see the different use cases and what you can do with the tool.

I also already wrote a full Gumloop review on this blog if you want to go check that out. So, I’m not going to go into much detail in this post to keep it fluff-proof.

To be honest, I’m really excited about this tool. And they did not pay me to say that. But, Max (the CEO) is extremely nice and gave me a promotional code. He allowed me to share it with my readers too, so if you want 20% off your monthly subscription, use the code MARKETERMILK at checkout.

Gumloop pricing

Gumloop has a freemium SaaS pricing model. You get 1,000 free credits when you complete the onboarding process. After that, you have a few different paid plans you can pick from that are based on credit usage.

Here are Gumloop’s pricing plans:

• Free: Gives you up to 1,000 credits.
• Starter: Starts at$97 per month with 30,000 credits.
• Pro: Starts at $297 per month with 75,000 credits.
• Enterprise: Unlimited everything, request pricing from their website.

Overall, this is a great AI marketing tool to check out if you work in marketing and want to automate parts of your job.

2. Relay.app

• Best for: Agencies, service providers, or customer success teams.
• Pricing: Includes free plan, then starts at $11.25 per month.

Founded in 2021, Relay is a clean and simple AI agent builder designed to help automate different workflows in your agency, firm, or freelance business.

It’s very similar to Gumloop in how visually appealing and nice it is to use. There are also tons of app integrations built in, so it makes it easy to connect with other tools you may already be using or paying for.

They also have an inspiration gallery so you can see examples of different workflow automations and intelligent agents you can create. For example, you can create an AI Discord bot with DeepSeek. Or, you can create an AI agent that enriches your CRM contacts with their personal LinkedIn information.

It’s a great tool if you run an agency and you deal with a lot of leads and contacts. It’s also great for customer success teams if they want to automate some of their support tickets.

Relay.app pricing

Relay.app has a free pricing plan and it also works on a credit usage basis.Here are Relay’s pricing plans:

• Free: Free for up to 500 LLM credits.
• Pro: Starts at $11.25 per month for 1,000 LLM credits and 1 seat.
• Team: Starts at $73.75 per month for 2,000 LLM credits and unlimited seats.
• Enterprise: A custom plan based on your needs. See pricing here.

You can also get a 20% discount if you pay for an annual plan upfront.

Relay.app ratings

Here’s what customers of Relay.app rate the platform on 3rd-party review sites:

• G2: 4.9 out of 5-star rating (from +58 reviews)
• Capterra: 5 out of 5-star rating (from +1 review)

3. HockeyStack

• Best for: Enterprise B2B marketing teams.
• Pricing: Starts at $2,200 per month.

Founded in 2021, HockeyStack is an AI agent builder designed for enterprise marketing teams. Originally, the company was designed for B2B revenue operations but it looks like they’ve made a pivot into the AI agent space.

HockeyStack is definitely on the premium side compared to the tools we’ve gone over so far. It’s not really a self-serve tool (as of writing this). And it’s mostly used by larger enterprises with big budgets.

But, HockeyStack is more than just an AI agent software. The platform also integrates with your data to give you internal insights with AI. It also has analytics and attribution data so you can measure multi-touch attribution.

It’s a powerful tool, and it makes sense why they went up-market and focused on larger enterprises. I recommend booking a demo if you work at a large company and are at the executive or director level.

HockeyStack ratings

Here’s what customers of HockeyStack rate the platform on 3rd-party review sites:

• G2: 4.7 out of 5-star rating (from +67 reviews)
• Capterra: 4.9 out of 5-star rating (from +26 reviews)

4. Stack AI

• Best for: Enterprise companies and SMBs.
• Pricing: Has a free plan, then starts at $199 per month.

Founded in 2022, Stack AI is a no-code platform designed to help you deploy automated workflows and AI apps (aka agents). Similar to HockeyStack, it was designed initially for larger enterprises over small businesses.

However, that’s what they advertise on their site. The pricing structure says otherwise, so it does feel more like a mid-market SaaS tool.

Similar to Gumloop, Stack AI also has a large library of templates you can pick and choose from. They also have some really cool customers across industries like healthcare, finance, and education. So if you’re also in those spaces, this tool is worth looking into.

Stack AI pricing

Stack AI has a generous free plan that includes up to 500 runs per month. However, if you need more runs, you’ll want to upgrade to a paid plan.

Here are Stack AI’s pricing plans:

• Free: $0 per month and comes with 500 runs per month.
• Starter: $199 per month and comes with 2,000 runs per month.
• Team: $899 per month and comes with 5,000 per month.
• Enterprise: Custom pricing with a custom amount of runs per month. Contact for pricing.

All paid plans come with a 7-day free trial so it’s worth signing up for and playing around with. You’ll also get a nice discount if you pay for an annual subscription.

Stack AI ratings

Here’s what customers of Stack AI rate the platform on 3rd-party review sites:

• G2: 4.7 out of 5-star rating (from +14 reviews)
• Capterra: Still needs to be reviewed (see link)

5. Voiceflow

• Best for: Customer support teams.
• Pricing: Includes a free plan, then starts at $50 per month.

Voiceflow has been around for some time now. And over the years, they’ve become the go-to platform for creating voice apps. Now, with AI and LLM capabilities, Voiceflow allows you to create customer support AI agents.

It has a visual editor that makes it easy to drag and drop elements onto a page. This makes it a great no-code tool if you don’t have extensive coding experience.

I highly recommend checking out this platform if you need help answering support tickets or need more bandwidth on the customer service side of your team or business.

Voiceflow pricing

Here are Voiceflow’s pricing plans:

• Sandbox: Free for 100K monthly AI tokens.
• Pro: $50 per month for 4M monthly AI tokens
• Team: $125 per month for 20M monthly AI tokens
• Enterprise: Custom pricing.

If you’d like to compare their plans or request enterprising pricing, be sure to check out their pricing page.

Voiceflow ratings

Here’s what customers of Voiceflow rate the platform on 3rd-party review sites:

• G2: 4.7 out of 5-star rating (from +39 reviews)‍
• Product Hunt: 4.5 out of 5-star rating (from +99 reviews)

6. OpenAI's Operator

• Best for: Consumer AI agents.
• Pricing: Starts at $199 per month.

OpenAI’s Operator recently launched and it looks like the ultimate AI agent platform the market has seen. I only included it higher in the list because it is still very new (and in beta) and out of reach for many users. That may change in the near future though.

You can give Operator pretty much any web-based task and it will go do it like a human. As Dharmesh Shah (CTO of HubSpot) said on LinkedIn: Operator’s launch means “every website suddenly becomes ‘programmable’ (even without APIs).” Which is a game changer for how we will automate tasks in the future.

For example, you will be able to tell Operator to go and book an entire trip for you — from booking your flights, all the way to your hotel.

There aren’t a lot of reviews on the platform yet, but this is a cool Reddit thread to go through if you want to see the power of the platform.

7. Devin AI

• Best for: Programming assistant.
• Pricing: Starts at $500 per month.

Devin AI has made a lot of buzz on tech X (Twitter) recently. It’s an AI agent for developers to help them code programs. It’s pretty much a junior developer who is your AI teammate.

The platform advertises it as a co-worker who can program. It can help you set up development environments, has its own shell, a built-in code editor, and even its own browser.

It’s a very promising tool for the development space. But, it has some mixed reviews. Then again, people in tech (especially engineers) are super skeptical about new technologies that claim to take over their jobs. And with good reason.

But, Devin AI seems to be promising and I can imagine it getting better over time.

8. AirOps

• Best for: SEO teams at large agencies or companies.
• Pricing: Includes free plan, then starts at $199 per month.

Founded in 2021, AirOps is an AI agent builder for SEO and organic growth teams (like me!). It’s another tool I’m really excited about for the marketing and content space.

Given I run an SEO agency and have a content marketing course, I’m always on the lookout for tools that can help me, my clients, and my students. This is one of those tools I’m actively using and playing around with right now so I thought I’d mention it in this list.

They also have an AirOps Academy which aims at teaching you how to use the platform and the different use cases it has. I highly recommend checking it out.

AirOps pricing

AirOps has a free plan for up to 1,000 credits (with 1 user seat). However, if you want more credits you will have to upgrade. And the tool does run a little more on the premium side so it’s probably best for larger agencies or companies.Here are AirOps’ pricing plans:

• Solo (free): $0 per month for up to 1,000 credits
• Solo (paid): $199 per month for up to 10,000 credits
• Scale: Custom pricing for businesses.
• Agency: Custom pricing for larger agencies.

If you want to compare plans or contact them for their Scale or Agency plans, be sure to check out their pricing page.

AirOps ratings

Here’s what customers of AirOps rate the platform on 3rd-party review sites:

• G2: 5 out of 5-star rating (from +1 review)
• Product Hunt: 5 out of 5-star rating (from +24 reviews)

9. Zep

• Best for: Enterprise AI agent development.
• Pricing: Includes free plan, then starts at $99 per month.

Zep (also known as Zep AI) is an AI tool that gives developers the “scalable blocks” to create production-ready AI agents and apps.

It’s not a no-code AI agent builder like the tools we’ve gone over so far. Rather, it’s a memory layer designed to enhance already existing AI agents. The tool helps developers programing technical AI agents to add better memory capabilities to their apps.

So if you develop AI apps had large companies, like WebMD or Athena (some of their customers), this is a tool you might want to look into. But if you’re a smaller business or Solopreneur, this is not the typical AI agent software you’d be looking for.

Zep pricing

Here are Zep’s pricing plans:

• Free: $0 per month, and includes 2,000 messages/month.
• Team: $99 per month, and includes 75K messages/month.
• Growth: $640 per month, and includes 500K messages/month.
• Enterprise: Contact for pricing.

If you want to compare the different plans or contact their sales team for enterprise pricing, check out their pricing page here.

10. Postman

• Best for: Engineers developing AI agents.
• Pricing: Includes free plan, then starts at $19 per month.

Founded in 2014, Postman is a powerful API platform created to help developers design, develop, test, and manage custom APIs. Over the years, Postman has also integrated a customer AI agent builder into their software as well.

The AI agent builder allows you to effortlessly do LLM testing, verify APIs, and simplify agent testing. It’s a very technical and developer-heavy platform. But, this AI agent builder does aim to make things a bit easier for less tech-savvy folks but integrating a no-code visual builder.

If you already have a programming background, this is a tool I highly recommend checking out. But if you’re looking for something more intuitive, you’re better off using something like Gumloop.

Postman pricing

Here are Postman’s pricing plans:

• Free: $0 per month, and includes 25 collection runs.
• Basic: $19 per user/month, and includes 10K monitor requests.
• Professional: $39 per user/month, and includes 25 packages.
• Enterprise: Custom requirements with custom pricing.

If you want to compare what each plan includes, or contact their sales team for enterprise pricing, check out their pricing page here.

Postman ratings

Here’s what customers of Postman rate the platform on 3rd-party review sites:

• G2: 4.7 out of 5-star rating (from +1,217 review)
• Capterra: 4.7 out of 5-star rating (from +493 reviews)

AI agents: Is it hype or the future?

This is it, AI agents are going to take your job (and mine). Just kidding. I think we are still a long way away from AI agents completely taking over our jobs.

But, these tools are getting more powerful. And I think you should actually be excited about that. This means that the side project you had can now be achievable with less work. It also means your job can become more creative and fun by automating the repetitive tasks you used to do.

If your job solely relies on manual tasks with no thinking, then these tools can feel like a threat. But if you’re in a creative field, these tools are going to be amazing for your growth in your career and work. I know I’m excited.

So are AI agents hype or the future? I believe they are the future. However, I do think there is a bit of hype around them currently. Tools like Gumloop or Postman have already proven themselves to be great. And pretty much every tool I mentioned in this list is amazing.

But I would be weary of other “cheap” tools that come out claiming to be AI agents. And we will see a lot of them in the next year as investors throw their money at founders creating the next AI craze.

Anyway, I hope you got some value from this post and enjoyed it as much as I enjoyed researching and writing it in Philz Coffee (one of my favorite coffee spots).

Happy creating!
