ChatterAPI is a chat API for developers who want to add messaging to their apps without building it from scratch. Instead of setting up your own real-time infrastructure, message storage and delivery logic, you call ChatterAPI and ship chat and messaging features in far less time. It's made for startups, indie hackers and product teams who'd rather spend their time on their core product than on maintaining chat backends. There's a free plan to start, so you can test it in your own app before upgrading.
