Stream is a very reliable and scalable product. I've never had any issues, downtime, or required special maintenance. The pricing is very competitive, and the support team is very helpful and responsive.

Ghulam Zaky

Product Manager

Chat is working great for us. We have many features that we didn’t have using our old chat provider. Our audience grew by 1,000%, so we have seen a steep increase in chat usage with a stable chat solution.

Ady Levy

VP of Engineering

The #1 Chat API & SDK for Custom Messaging Apps (60)

Stream is working great. We had so many limitations to what we wanted to do with Codepen before we found Stream. Stream unlocked fundamental activities that make Codepen what it is today

Chris Coyier

Co-Founder

One problem with vendors claiming to provide an OOTB experience is that, at some point, you find the edge of that box. But with Stream, there is always an escape hatch at the edge of the box that prevents us from looking elsewhere, especially as we continue to create more experiences with custom and branded UI elements.

Jonathan Blair

CTO

The #1 Chat API & SDK for Custom Messaging Apps (61)

When we began our search for vendors, we found Stream. It had a great Javascript SDK and documentation that would accelerate and streamline the integration process for our customers.

Samuel Abraham

SVP of Corporate Development & Channel Partnership

The #1 Chat API & SDK for Custom Messaging Apps (62)

Integrating Stream Chat with our existing systems was smooth, thanks to its well-documented API and support from its customer success team. This ease of integration allowed us to quickly implement the chat functionality without causing disruptions in our ongoing operations.

Jerome Muldoon

Chief Customer Officer

The #1 Chat API & SDK for Custom Messaging Apps (63)

Instead of just telling us a price and a plan, Stream is committed to understanding our business so we can architect, build, and customize our apps exactly how we want them.

Todd Zander

VP & GM

The #1 Chat API & SDK for Custom Messaging Apps (64)

When we started the migration, we started routing the data to Stream from our previous chat provider. Stream's migration process made it really easy for us to do that. The entire migration went off without a hitch. It was phenomenal.

Ashik Manandhar

Director of Engineering

The #1 Chat API & SDK for Custom Messaging Apps (65)

Our development team did two MVP builds—one with Sendbird and one with Stream. Their feedback was that the Stream SDK was easier to work with; it only took three days to complete. They liked the available functionality and thought it would be the fastest route to market.

Jerome Muldoon

Chief Customer Officer

We've leveraged Stream to provide innovative audience engagement via chat, with custom reactions, verified status indicators, and user metadata to create immersive experiences. We wrapped all the features of Stream into a simple module that can be dropped onto a page to add robust chat functionality to any experience in seconds.

Jonathan Blair

CTO

We chose Stream because of its ease of integration, impressive documentation, and robust feature catalog. It only took one developer a few hours to integrate the React Native SDK. Now, we see an average of 50% growth YoY thanks to the newfound ability for our members to communicate via Stream Chat.

Swapnil Saurav

Co-Founder

The #1 Chat API & SDK for Custom Messaging Apps (66)

Stream Chat's global edge network was a huge selling point for us. Now, we can confidently say to our customers it doesn't matter where our servers are; messages will always be delivered and feel instantaneous.

Jefferson Heard

VP of Product Development

The integration with Stream Chat was remarkably quick. We rewrote the entire system, addressing not just the migration but also running both systems in parallel. The transition involved collaboration with Stream developers, ensuring a seamless process and no disruption to user experience.
