| Who it's not for | Support-widget-only needs . use a live-chat tool | Solo founders needing a basic chat widget by Friday |

| Support quality | No evidence in sources reviewed | Review base too thin to judge |
| Public sentiment | The few public commenters praise TalkJS as customizable and easy to integrate, but review volume is tiny.⁴ | Third-party reviews are sparse: G2 names it a High Performer with mostly positive feedback, while at-scale pricing draws the loudest criticism.12 |
