It"s true to size with a slim fit. If you usually wear a medium, it should fit just right.

We needed chat and didn't want to build it ourselves because it needs to be really great. The TalkJS team is laser-focused on chat, and we're focused on building a great auction marketplace.

Because implementing TalkJS was as fast and easy as it was, we were able to greenlight and move this project along very quickly. Had we not chosen this path, the feature would have either been delayed, or shelved due to the resources needed to implement it.

TalkJS offered a great balance of features and support at an affordable price. The integration process was one of the smoothest we've experienced.
Sergiej Rewiakin
Head of Tech at Caspar Health
The power of TalkJS is that it's highly customizable and user-friendly. We can offer our customers a plug and play solution and give them the possibility to adjust the chat widget to their needs.
Paul Van Den Broek
Product Manager, Coosto
The flexibility lets us implement as we wish—starting simple and adding custom functionality as we go.
Ben Klenk
Co-founder & CEO, Hotplate
I was able to demo a working end-to-end chat conversation in our platform in just a 2 to 3 day timeframe. The POC took less than an hour.
Jun Minon
Product Engineer, Xolo
The main reason we chose TalkJS was their reputation, APIs and ability to host the solution.
Peter Lu
Head of Product, RapidSOS
We chose TalkJS because it aligned well with our usage, as we have a large number of users but low usage per user.
