A side-by-side editorial comparison of Discourse and Plain — release velocity, themes, recent moves, and the top alternatives to consider.

Discourse vs Plain: at a glance
What is Discourse?
Forum platform doubles down on AI agents and enterprise auth atop a steady monthly cadence
Discourse ships on a reliable monthly release train, with intermediate releases reserved for critical security fixes. Beyond the version bumps, the substantive work is in its AI plugin and enterprise authentication: connecting external MCP servers to its AI bot, managing AI credentials, and auto-provisioning accounts via SSO.
What is Plain?
Support platform betting hard on an agentic AI responder as the default first touch
Plain is a customer-support tool whose recent work is dominated by two AI agents: Ari (autonomous responder) and Sidekick (assistant). In this window Ari was rebuilt from a classify-and-handoff workflow into an agentic, search-first default first responder, suggested replies were moved onto the same engine, and Sidekick gained tool integrations and a Slack presence. Platform plumbing (Attio, Linear, workflows) continues alongside.

Discourse

Forum platform doubles down on AI agents and enterprise auth atop a steady monthly cadence
◆ Current state
Discourse ships on a reliable monthly release train, with intermediate releases reserved for critical security fixes. Beyond the version bumps, the substantive work is in its AI plugin and enterprise authentication: connecting external MCP servers to its AI bot, managing AI credentials, and auto-provisioning accounts via SSO.
◆ Where it's heading
Two threads dominate: turning the AI bot into an extensible agent platform (custom MCP tool providers, shared AI credentials) and hardening enterprise identity (SSO auto-provisioning). The monthly/intermediate release split reflects a maturing operational rhythm.
◆ Prediction
Expect further AI-bot extensibility — more tool integrations and admin controls around the MCP surface — alongside the regular monthly cadence.
Plain
5.0SUPPORT
Support platform betting hard on an agentic AI responder as the default first touch
◆ Current state
Plain is a customer-support tool whose recent work is dominated by two AI agents: Ari (autonomous responder) and Sidekick (assistant). In this window Ari was rebuilt from a classify-and-handoff workflow into an agentic, search-first default first responder, suggested replies were moved onto the same engine, and Sidekick gained tool integrations and a Slack presence. Platform plumbing (Attio, Linear, workflows) continues alongside.
◆ Where it's heading
The direction is unmistakably AI-native support: make the agent the default first responder, give it agentic search and tool access, and meet users where they work (Slack, the composer, workflows). The non-AI releases — CRM connectors, workflow actions, API additions — increasingly exist to feed context to that agent.
◆ Prediction
Expect Ari and Sidekick to keep absorbing the support workflow — more tool integrations, deeper autonomy, and tighter loops between suggested replies and autonomous sends — with platform/API work continuing to supply the context they rely on.
