Deciding to build a chatbot is just the first step. Next, you’ll need to consider the different bot frameworks that are available and choose the one that’s right for you. There are quite a few to sort between and the industry is pretty new, so finding the important stuff on each can be a bit tricky. 

We’ve run through all of the latest blogs, press releases and lengthy LinkedIn posts to find the biggest and best chatbot frameworks. 

Really, really good chatbot frameworks

1. Microsoft Bot Framework

  • build, publish and manage intelligent chatbots. 
  • create bots that will speak, listen, understand and learn. 
  • use to interact with users on Skype, Slack, Facebook Messenger, Kik and your own website. 
  • supports Node.js, C# and .NET languages.

Top of many shortlists from those in the know is the Microsoft Bot Framework. It’s robust, customisable and offers developers serious power. The framework uses Microsoft Bot Builder to allow developers the freedom to plug-and-play with the builder’s pre-existing code blocks. 

The bot uses a really clever component that’s called the Language Understanding Intelligent Service, or LUIS (brilliant, love that), which makes sure all of the bot’s responses are natural and conversational. 

It’s already being used by Adobe to ease friction as customers search for error codes as they experiment with the software and Spanish football’s top division LaLiga is using it too. If you’ve been living under a rock and you’re not sure who Lionel Messi is, then you can ask the bot and it will respond with everything you could ever need to know about the 🐐 (G.O.A.T)

2. Amazon Lex

  • build, test and deploy chatbots from the easy-to-use Amazon Lex console. 
  • high-quality speech recognition and natural language understanding. 
  • integrations with Salesforce, HubSpot and Zendesk. 
  • create a bot that works on Slack and Facebook Messenger.

Versatile and powerful, Amazon Lex could be the framework for you. Developers can use the framework to create bots that communicate via text or voice. You can create actual spoken conversations with Amazon Lex. As you’d expect, the framework integrates with Amazon’s virtual assistant Alexa too. 

The natural language understanding component of Amazon Lex works out the intent of someone’s query, leading to highly engaging and effective conversations. There’s no higher praise than from our friends over at HubSpot. 

CTO and Founder of HubSpot, Dharmesh Shah (who we pestered in a Boston bar until he had drinks with us - true story) is a big fan of Amazon Lex. His clever team have used the framework to create GrowthBot which gives marketers and salespeople access to the data they need quickly via a conversational interface.

3. Botpress

  • based on modular architecture so new features can be added via the Botpress Marketplace. 
  • used by over 40,000 developers and businesses, including LinkedIn and Deloitte.
  • built-in connector tools.
  • active community of developers who are making improvements all the time. 

If you’re like us and you love a good interface, then Botpress is the framework for you. Pack it up, blog over - we’re done. It’s created “by developers, for developers” but the interface makes bot-building simple and loads of fun for anyone with a passing interest in conversational marketing.

It’s a bit different from other frameworks in that you download Botpress to your computer, so everything is done there rather than on the cloud. This isn’t really a negative in any way. You just build your bot locally and deploy it wherever you’d like. 

Like the others, the framework uses natural language understanding components that make sure every message is responded to in the right way. Once everything’s up and running, the analytics tool gives you the data you need to make the bot more and more intelligent.

4. Dialogflow

  • optimised for the Google Assistant. 
  • build bots for users on Facebook Messenger, Twitter, Skype, Slack and other places. 
  • supports over 20 languages, including PHP, Node.js and Java.
  • especially good for developing NLP based applications. 

Last, but by no means least, is Dialogflow - Google’s contribution to the growing number of chatbot frameworks. You might have encountered this one in the past under its previous guise of API.AI. After a rebrand and quick coat of paint in 2017, Dialogflow is now ready to help you create the perfect bot. 

Dialogflow is powered by Google’s machine learning, allowing you to build both voice and text-based conversations for users. Like the others on this list, Dialogflow will listen closely to each user, determine their needs and respond in the most effective way. 

It’s used by some pretty big names like ticketmaster, Giorgio Armani and most importantly of all - Domino’s Pizza. Hungry users can place orders through the bot which is clever enough to deal with your really weird request for pineapple, tuna, gherkins and extra olives pizza.

These are just four of the biggest and best chatbot frameworks currently available. There’s no real winner to declare here, I’m afraid. All of them are intuitive, customisable and more than capable. Most frameworks offer free trials so it’s absolutely worth having a play around to see which feels right for you.
