| Support quality | No support evidence in reviewed sources. | No support evidence in sources |
| Public sentiment | Reviews are positive but sparse: 4.6/5 on G2 (195 reviews) and 4.0 on Trustpilot (13), with users praising fast adoption and less tool-switching.² | Users praise consolidation power but many report bloat, pricing changes, and trimming usage down to a few features.10 |
