1.Favicon of Pylon

Pylon

Direct replacement
B2B support in the customer's own Slack channel
Sales-gated

The closest competitor for B2B support run out of shared Slack channels. Plain publishes a custom API migration path for Pylon specifically, and unlike Pylon it publishes seat prices on its own pricing page.

2.Favicon of Front

Front

Direct replacement
Shared inbox with per-conversation AI billed separately
$25/seat/mo·+$0.05 per conversation

Both sell a per-seat inbox to B2B teams, but Front prices purely per seat where Plain bundles the first 1 or 3 seats into a base fee, and Front's guest access is conversation-scoped rather than an unlimited free viewer seat.
